Quick Answer

Most Ozempic side effects are short-term, but some can last months or years after stopping the medication, including pancreatitis, vision problems, kidney injury, and skin changes.
In one 2-year study, 3% of Ozempic injection users experienced vision complications compared to 1.8% taking a placebo.
Gastrointestinal issues like nausea, vomiting, diarrhea, or abdominal pain are among the most commonly reported side effects.
A recent meta-analysis of about 35,000 patients found semaglutide is not associated with a higher risk of pancreatitis compared to placebo.

Ozempic, known by its generic name semaglutide, is a medication approved for Type 2 diabetes and increasingly used for weight loss. While many of its side effects are temporary and improve as your body gets used to the drug, some potential long-term issues exist. These can include serious conditions like pancreatitis, vision problems, and kidney injury. For example, a 2-year study showed that 3% of Ozempic injection users developed vision complications, compared to 1.8% of those taking a placebo. Most commonly, people experience gastrointestinal problems such as nausea, vomiting, diarrhea, or abdominal pain. These symptoms usually appear when you first start Ozempic or when your dose is increased, and they often get better within about three months. It is important to know about these potential effects when considering Ozempic treatment.

What are the Most Common Ozempic Side Effects?

Most side effects that people experience when taking Ozempic are mild to moderate. These symptoms tend to improve over time as the body adjusts to the medication. Common issues include discomfort in the abdomen, a reduced desire to eat, indigestion, and heartburn. Some individuals also report reactions at the injection site, such as redness, swelling, or itching where the shot was given. These symptoms are most likely to show up when someone first starts taking Ozempic or after their doctor increases the dose. Generally, these temporary effects subside, and many people find that their Ozempic side effects improve after about three months of consistent use.

When we consider the full picture of Ozempic's effects, it's clear that the initial phase of treatment often involves a period of adjustment. This is when the body is learning to cope with the new medication and its impact on various systems. The gastrointestinal tract is particularly sensitive, leading to the common complaints of nausea, vomiting, and abdominal pain. These symptoms are a direct result of how Ozempic works, specifically by slowing down gastric emptying. While this mechanism helps with blood sugar control and weight loss, it can also lead to feelings of fullness and discomfort. Patients are often advised to start with a low dose and gradually increase it, a process known as titration, to help minimize these initial side effects. This slow approach allows the body more time to adapt, potentially making the treatment more tolerable in the long run. If these common side effects persist or become severe, it is crucial for individuals to discuss them with their healthcare provider. Managing these symptoms effectively is key to maintaining adherence to the medication and achieving its intended benefits.

Injection site reactions are another common, though generally minor, concern. These local reactions are typically mild and do not indicate a serious problem with the medication itself. They are often a response to the needle or the solution being injected, similar to reactions seen with other injectable medications. Applying a cool compress or using over-the-counter creams can sometimes help alleviate the redness, swelling, or itching. It is important to distinguish these local reactions from more widespread allergic responses, which are far less common but require immediate medical attention. The vast majority of people who experience injection site reactions find that they are temporary and do not interfere with their ability to continue treatment. The overall safety profile of Ozempic highlights that while common side effects are frequent, they are usually manageable and resolve with time. The focus remains on ensuring patients are well-informed and supported throughout their treatment journey, especially during the initial adjustment period.

Understanding Gastrointestinal Discomfort

Gastrointestinal issues are a hallmark of Ozempic treatment. Nausea, vomiting, diarrhea, and abdominal pain are frequently reported. These symptoms can range from mild to severe. In some cases, if not managed properly, they could lead to more serious issues like dehydration or malnutrition. This is especially true if a person experiences persistent vomiting or diarrhea. The medication works by mimicking a natural hormone called GLP-1, which affects digestion. It slows down how fast food moves through the stomach. While this helps people feel full longer and can lead to weight loss, it can also cause digestive upset.

Many people find that these symptoms lessen after the first few weeks or months. For most, Ozempic side effects after 3 months improve. This timeframe often aligns with the body's adaptation period. Healthcare providers often recommend starting with a low dose of Ozempic and slowly increasing it over several weeks. This gradual increase, known as titration, helps the body adjust to the medication, which can reduce the severity of these initial side effects. If symptoms become too bothersome, a doctor might suggest strategies like eating smaller meals, avoiding greasy foods, or taking anti-nausea medication. It's important for individuals to communicate openly with their healthcare team about any persistent or severe gastrointestinal discomfort.

Injection Site Reactions

Beyond the internal effects, some people may notice reactions where they inject Ozempic. These reactions include redness, swelling, or itching at the injection site. These are usually localized and not a sign of a severe systemic problem. They tend to be mild and temporary. Such reactions are common with many injectable medications. They happen because of the needle itself or the medication irritating the skin locally.

To minimize injection site reactions, it is important to rotate injection sites. This means not injecting into the exact same spot each time. Common injection sites include the abdomen, thigh, or upper arm. Using a different area for each injection can help prevent irritation and allow previous sites to heal. If a reaction occurs, a cool compress can often provide relief. Persistent or severe reactions, or any signs of infection, should be discussed with a healthcare provider. While uncomfortable, these reactions rarely lead to discontinuation of Ozempic. They are a minor inconvenience for most users, especially compared to the benefits of the medication for blood sugar control or weight management.

Can Ozempic Cause Long-Term Effects?

Yes, Ozempic has been linked to certain long-term side effects. While many common side effects are temporary, some problems may last for months or even years after a person stops taking the medication. These potential long-term effects include conditions such as pancreatitis, vision problems, kidney injury, and changes to the skin, sometimes referred to as "Ozempic face." Clinical trials have studied Ozempic for varying lengths of time to understand its effects. For instance, studies for type 2 diabetes lasted 30 weeks. Trials looking at cardiovascular outcomes, known as SUSTAIN trials, extended for 104 weeks. In adults with type 2 diabetes and chronic kidney disease, Ozempic was studied for as long as 41 months. This extensive research helps us understand the potential impacts of long-term use. Ozempic long-term side effects are a significant area of focus for patients and healthcare providers.

The discussion around long-term effects is critical because Ozempic is often prescribed for chronic conditions like type 2 diabetes and obesity, meaning many individuals may take it for extended periods. When we consider the duration of clinical trials—up to 41 months in some cases—it gives us insight into what might occur over several years of use. While the immediate benefits of blood sugar control and weight loss are often clear, understanding the potential for enduring complications is equally important. Pancreatitis, for example, is a serious inflammation of the pancreas that has been reported, though its direct link to Ozempic is still being investigated. Similarly, vision problems, particularly the worsening of diabetic retinopathy, have been observed, especially when blood sugar levels improve very quickly. This rapid change can sometimes stress the eyes, leading to temporary or even more lasting issues.

Kidney injury is another concern that has emerged in discussions about Ozempic's long-term profile. While Ozempic has shown protective effects on kidney health in some contexts, there have also been reports of kidney issues. This highlights the complex interplay between the medication, existing health conditions like diabetes, and individual patient responses. Changes in skin, sometimes colloquially termed "Ozempic face" or "Ozempic body," refer to alterations in facial or body fat distribution due to rapid weight loss. While not a direct medical complication, these cosmetic changes can be a significant concern for some users. It is essential for patients to have open conversations with their healthcare providers about these potential long-term effects, weighing the benefits against the risks for their individual health profile. The ongoing monitoring and reporting of side effects continue to refine our understanding of Ozempic's full impact over time.

Pancreatitis Risk

Pancreatitis, which is inflammation of the pancreas, has been reported in some people taking Ozempic. However, it is not entirely clear if Ozempic directly causes this condition. In one 2-year study, 8 people who received injectable Ozempic developed pancreatitis. In comparison, 10 people in the placebo group, who did not receive the active medication, also experienced pancreatitis. This suggests that the occurrence might not be solely due to the drug. In studies combining data from oral semaglutide (Rybelsus/Ozempic tablet), 6 people reported pancreatitis, while only 1 person in the comparison group did. However, a more recent meta-analysis, which looked at data from about 35,000 patients, found that semaglutide is not linked to a higher risk of pancreatitis when compared to a placebo. Despite this, cases of pancreatitis continue to be reported by people using the medication.

Vision Changes

Ozempic may also affect vision. It has the potential to worsen an existing eye condition called diabetic retinopathy. This can happen especially when blood sugar levels improve very quickly. In a 2-year study, 3% of Ozempic injection users experienced complications related to diabetic retinopathy, compared to 1.8% of those taking a placebo. In pooled trials, including both placebo and active-controlled studies, 4.2% of oral semaglutide users reported diabetic retinopathy. This was slightly higher than the 3.8% in the comparison group. Another potential eye condition that Ozempic might cause is non-arteritic anterior ischemic optic neuropathy (NAION). This condition occurs when the optic nerve does not receive enough blood supply, which can affect vision.

Kidney Damage and Function Loss

Kidney issues are another area of concern for long-term Ozempic users. While the medication is often used by individuals with type 2 diabetes, who are already at risk for kidney problems, there have been reports of kidney injury and a loss of kidney function. This is a serious consideration, as healthy kidney function is vital for overall health. The exact mechanisms by which Ozempic might contribute to kidney damage are still being investigated, but it is important for healthcare providers to monitor kidney function in patients taking the medication long-term.

Patients with pre-existing kidney conditions may be at a higher risk. Regular blood tests to check kidney function are typically part of the monitoring process for individuals on Ozempic. If any signs of kidney problems emerge, such as changes in urination or swelling, it is crucial to seek medical advice promptly. The balance between managing diabetes and weight, and protecting kidney health, is a delicate one that requires careful consideration and ongoing medical supervision for those on long-term Ozempic therapy.

Changes in Body Composition

Rapid weight loss, which is a common effect of Ozempic, can lead to noticeable changes in body composition. This is often described by terms like "Ozempic face" or "Ozempic body." These phrases refer to the loss of fat from areas like the face, leading to a more gaunt or aged appearance, or changes in overall body contours. While weight loss is often a desired outcome, the speed at which it occurs can sometimes result in these cosmetic changes.

These changes are not typically a direct medical complication of the drug itself, but rather a consequence of significant fat reduction. For some individuals, these body composition changes can impact self-image and satisfaction with the weight loss journey. It is important for patients to have realistic expectations about how their body might change with rapid weight loss and to discuss any concerns with their healthcare provider. Sometimes, a slower, more gradual weight loss approach might be preferred by some individuals to mitigate these effects.

What is the Risk of Pancreatitis with Ozempic?

The risk of pancreatitis, an inflammation of the pancreas, has been reported in some individuals taking Ozempic. However, it is not definitively clear if Ozempic directly causes this condition. In one 2-year study, 8 people who were taking injectable Ozempic developed pancreatitis. In the same study, 10 people who were taking a placebo, meaning they received no active medication, also experienced pancreatitis. This comparison suggests that pancreatitis can occur in both groups, making a direct causal link to Ozempic unclear in this specific instance. When looking at pooled studies involving oral semaglutide (the tablet form of Ozempic or Rybelsus), 6 people reported pancreatitis, compared to only 1 person in the group not taking the medication.

Despite these individual reports, a more recent and comprehensive meta-analysis, which included data from approximately 35,000 patients, found that semaglutide is not associated with a higher risk of pancreatitis compared to a placebo. This large-scale analysis provides strong evidence that the overall risk may not be elevated. Even with this evidence, there are still cases where people taking the medication report experiencing pancreatitis. "While more evidence is coming out showing no association between Ozempic and pancreatitis, there continue to be cases of people who are taking the medication reporting it," said the Official Answer by Drugs.com. This highlights the importance of being aware of the symptoms. Signs of pancreatitis can include severe upper stomach pain that might spread to the back, feelings of nausea or vomiting, and a rapid heartbeat. Pancreatitis usually resolves within two weeks, but in rare cases, it can last longer. One patient in clinical trials reported chronic, or long-term, pancreatitis while taking Ozempic. Potential complications of Ozempic for weight loss often include discussions around pancreatitis.

Clinical Trial Findings on Pancreatitis

The clinical trials provided varying insights into the connection between Ozempic and pancreatitis. The 2-year study comparing injectable Ozempic to a placebo showed a slightly lower incidence of pancreatitis in the Ozempic group (8 cases) compared to the placebo group (10 cases). This specific finding does not support a direct increase in risk due to the medication. However, when looking at oral semaglutide, the numbers shifted, with 6 reports of pancreatitis in the active treatment group versus 1 in the comparator group. These differing results across various study designs and forms of semaglutide underscore the complexity of establishing a clear link.

It's important to remember that these are relatively small numbers of events within large study populations. Pancreatitis itself can be caused by many factors, including gallstones, high triglyceride levels, and alcohol use, some of which may be present in the patient populations studied. Therefore, attributing every case directly to the medication can be challenging. The larger meta-analysis, which combines data from many studies and thousands of patients, offers a broader perspective. Its conclusion that semaglutide is not associated with a higher risk of pancreatitis compared to placebo is a significant finding for understanding the overall safety profile of the drug.

Symptoms and Management of Pancreatitis

Recognizing the signs of pancreatitis is crucial for anyone taking Ozempic. The most prominent symptom is severe pain in the upper part of the stomach, which can sometimes spread to the back. This pain is often described as sharp or burning. Other common symptoms include nausea and vomiting, which can be intense, and a rapid heartbeat. In some cases, people may also experience fever or tenderness in the abdomen. If you experience any of these symptoms, it is vital to seek medical attention immediately. Early diagnosis and treatment can help prevent more severe complications.

Pancreatitis can range from mild to severe. Mild cases often improve with supportive care, such as intravenous fluids and pain management, typically within a couple of weeks. However, severe pancreatitis can lead to serious complications, including organ failure, and may require intensive care. While most cases resolve, there was one report of chronic pancreatitis in a patient during Ozempic clinical trials. Chronic pancreatitis is a long-lasting condition that can lead to permanent damage to the pancreas and ongoing digestive issues. Therefore, any suspicion of pancreatitis warrants prompt medical evaluation to ensure appropriate management and monitoring.

How Does Ozempic Affect Vision?

Ozempic may impact vision, particularly by worsening an existing eye condition called diabetic retinopathy. This can occur when blood sugar levels improve very rapidly. Diabetic retinopathy is a complication of diabetes that damages the blood vessels in the retina, the light-sensitive tissue at the back of the eye. When blood sugar levels drop too quickly, it can sometimes put stress on these already fragile blood vessels, leading to a temporary worsening of the condition. In a 2-year study, 3% of Ozempic injection users experienced complications related to diabetic retinopathy. This was compared to 1.8% of those taking a placebo, indicating a higher incidence in the Ozempic group.

Furthermore, in pooled placebo and active-controlled trials, 4.2% of oral semaglutide (Rybelsus/Ozempic tablet) users reported diabetic retinopathy. This was slightly higher than the 3.8% reported in the comparator group. These statistics suggest a potential link, especially for individuals already prone to diabetic eye conditions. Beyond diabetic retinopathy, Ozempic might also cause a condition known as non-arteritic anterior ischemic optic neuropathy (NAION). NAION happens when the optic nerve, which carries visual information from the eye to the brain, does not receive enough blood supply. This lack of blood flow can lead to sudden vision loss in one eye. Given these potential effects, it is very important for patients to monitor for any changes in their vision and to discuss these promptly with their healthcare provider. Regular eye exams are especially crucial for individuals with diabetes who are taking Ozempic.

Impact on Diabetic Retinopathy

Diabetic retinopathy is a serious complication for many people with diabetes. It's caused by damage to the blood vessels in the retina due to high blood sugar levels over time. Ozempic helps lower blood sugar, which is generally good for managing diabetes. However, when this reduction happens too quickly, it can sometimes trigger or worsen diabetic retinopathy. This phenomenon is not unique to Ozempic and has been observed with other intensive blood sugar control treatments. The rapid metabolic changes can stress the delicate blood vessels in the eyes, leading to temporary swelling or leakage.

The clinical trial data provides specific numbers for this risk. In one 2-year study, 3% of people using Ozempic injections experienced complications with their diabetic retinopathy, compared to 1.8% of those on a placebo. This nearly double rate of complications in the active treatment group is a significant finding. For oral semaglutide, the numbers were 4.2% reporting diabetic retinopathy in the treatment group versus 3.8% in the comparator group in pooled trials. While the difference here is smaller, it still points to a potential concern. Patients with a history of diabetic retinopathy or those at high risk should be particularly vigilant and undergo regular eye examinations while on Ozempic. Close collaboration between endocrinologists and ophthalmologists is often recommended to manage this risk effectively.

Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION)

Another potential eye condition linked to Ozempic is non-arteritic anterior ischemic optic neuropathy, or NAION. This condition is characterized by a sudden, painless loss of vision in one eye, often occurring upon waking. It happens when the optic nerve, which is crucial for transmitting visual signals to the brain, does not receive an adequate blood supply. The exact mechanism by which Ozempic might contribute to NAION is not fully understood. However, changes in blood pressure or blood flow dynamics, which can be influenced by medications like Ozempic, might play a role.

NAION is a serious condition because the vision loss it causes can be permanent. While it is considered a rare side effect, its potential severity makes it important to be aware of. Any sudden change in vision, such as blurriness, loss of peripheral vision, or a dark spot in the field of vision, should prompt immediate medical attention. Early diagnosis and intervention may help manage the condition, although treatment options for NAION are limited. Patients should discuss their full medical history, including any previous eye conditions, with their healthcare provider before starting Ozempic. This allows for a thorough assessment of individual risk factors.

Are There Other Serious Long-Term Complications?

Yes, beyond pancreatitis and vision issues, there are other rare but serious long-term side effects associated with Ozempic. These can include problems with the gallbladder, kidney issues, and a potential risk of thyroid tumors. The medication can also lead to gastrointestinal complications such as gastroparesis, often called stomach paralysis, or intestinal blockage. While these conditions are uncommon, their potential severity makes them important to consider for long-term users. Ozempic long-term issues detailed outlines these concerns. Rapid weight loss, a common effect of Ozempic, can also result in changes to body composition that are sometimes described as “Ozempic face” or “Ozempic body.”

When we delve into these other serious complications, gallbladder problems frequently arise. Ozempic's mechanism of slowing digestion and affecting metabolism can sometimes contribute to the formation of gallstones. Gallstones can lead to painful attacks, inflammation of the gallbladder (cholecystitis), and in severe cases, may require surgery to remove the gallbladder. While not everyone on Ozempic will develop gallstones, individuals who experience rapid weight loss from any cause are known to have an increased risk. Therefore, symptoms like severe pain in the upper right abdomen, nausea, or vomiting should be evaluated promptly by a healthcare professional to rule out gallbladder issues.

Kidney issues, including kidney damage and loss of function, are another concern. Although Ozempic has shown some renoprotective (kidney-protective) effects in certain populations with type 2 diabetes, there have been reports of acute kidney injury in some users. This can be particularly concerning for individuals who already have compromised kidney function or other risk factors. Dehydration, often a consequence of gastrointestinal side effects like severe vomiting or diarrhea, can also contribute to kidney problems. Regular monitoring of kidney function through blood tests is essential for patients on long-term Ozempic therapy to detect any potential issues early.

The risk of thyroid tumors, including cancer, is a significant safety warning associated with GLP-1 receptor agonists like Ozempic and Wegovy. While studies in rodents have shown these medications can cause thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), it is not yet known if this risk translates to humans. However, due to this preclinical finding, a strong contraindication exists: Ozempic should not be used in individuals with a personal or family history of MTC, or in those with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2), a genetic condition that increases the risk of MTC. Patients are advised to report any symptoms such as a lump in the neck, hoarseness, trouble swallowing, or shortness of breath, as these could be signs of thyroid cancer.

Gastrointestinal complications like gastroparesis, or stomach paralysis, and intestinal blockage, while rare, are severe. Gastroparesis involves a significant slowing or stopping of stomach emptying, leading to symptoms like persistent nausea, vomiting, early fullness, and bloating. This can lead to malnutrition and dehydration. Intestinal blockage, where food or stool cannot pass through the intestines, is an emergency condition causing severe abdominal pain, vomiting, and inability to pass gas or stool. These conditions underscore the importance of careful monitoring of gastrointestinal symptoms, especially if they become severe or persistent.

Finally, the phenomenon of "Ozempic face" or "Ozempic body" refers to the aesthetic changes that can occur with rapid weight loss. Losing significant amounts of fat quickly can lead to a hollowed-out appearance in the face, making individuals look older or gaunt. Similarly, overall body fat reduction can alter body contours, sometimes in ways that individuals find undesirable. While not a medical complication, these cosmetic effects can impact a person's body image and satisfaction with their weight loss. It is part of the broader discussion that patients should have with their healthcare providers about the comprehensive effects of Ozempic treatment.

What Important Safety Information Should Users Know?

It is critical for anyone considering or currently using Ozempic, or its related medication Wegovy (which also contains semaglutide), to be aware of important safety information. Wegovy may cause serious side effects, including the possibility of thyroid tumors, which can include cancer. This is a significant concern that patients must understand. If you notice any unusual symptoms such as a lump or swelling in your neck, persistent hoarseness, difficulty swallowing, or shortness of breath, you must tell your healthcare provider immediately. These symptoms could be signs of thyroid cancer.

Studies conducted with rodents have shown that Wegovy and other medications that work in a similar way can cause thyroid tumors, including a type of thyroid cancer. However, it is not yet known whether Wegovy will cause these types of thyroid tumors or a specific type of thyroid cancer called medullary thyroid carcinoma (MTC) in humans. Because of this potential risk, there are specific situations where Wegovy should not be used. You should not use Wegovy if you or any of your family members have ever had medullary thyroid carcinoma (MTC). Similarly, if you have an endocrine system condition known as Multiple Endocrine Neoplasia syndrome type 2 (MEN 2), Wegovy is not recommended. This information is crucial for patient safety and guides prescribing decisions. Wegovy Important Safety Information details these warnings.

Thyroid Tumor Risk

The warning about thyroid tumors is one of the most serious safety messages for semaglutide medications like Ozempic and Wegovy. While the connection to human thyroid cancer, specifically medullary thyroid carcinoma (MTC), is not yet confirmed, the findings from animal studies are significant enough to warrant a black box warning. This means it is a serious potential risk that must be clearly communicated. The C-cells in the thyroid gland are where MTC originates, and these are the cells that were affected in the rodent studies.

For patients, understanding this risk means being vigilant for specific symptoms. A lump or swelling in the neck might be felt or seen. Hoarseness that doesn't go away, trouble swallowing food or liquids, or feeling short of breath can all be indicators. These symptoms are not always cancer, but they must be investigated by a doctor to rule out serious conditions. The presence of these symptoms requires prompt medical attention to ensure early diagnosis if cancer is present.

Contraindications for Use

Due to the potential for thyroid tumors, specific contraindications have been established for Wegovy and, by extension, Ozempic. A contraindication means that the medication should not be used under certain circumstances because the risks outweigh any potential benefits. The most critical contraindication is a personal or family history of medullary thyroid carcinoma (MTC). If anyone in your immediate family has had this rare form of thyroid cancer, you should not use these medications. This is because there might be a genetic predisposition that increases your risk.

Another absolute contraindication is having Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). MEN 2 is a rare genetic disorder that causes tumors in several endocrine glands, including the thyroid, where it significantly increases the risk of MTC. For individuals with MEN 2, using semaglutide-based medications could potentially exacerbate this pre-existing risk. Healthcare providers screen patients for these conditions before prescribing Ozempic or Wegovy to ensure patient safety. It is vital for patients to provide a complete and accurate medical and family history to their doctor to help make the safest treatment decisions.

Other Serious Side Effects

Beyond the specific thyroid tumor risk, Ozempic and Wegovy can have other serious side effects that require attention. These include the potential for acute pancreatitis, which we discussed earlier, characterized by severe abdominal pain. Gallbladder problems, such as gallstones, can also develop, leading to pain and potentially requiring surgical intervention. Acute kidney injury has been reported, especially in cases of severe dehydration from gastrointestinal side effects.

Severe allergic reactions are also possible, though rare. Symptoms can include swelling of the face, lips, tongue, or throat, difficulty breathing, severe rash, or dizziness. These are medical emergencies and require immediate attention. The medication's impact on blood sugar levels can also lead to hypoglycemia (low blood sugar), particularly if used with other diabetes medications like insulin or sulfonylureas. Symptoms of hypoglycemia include dizziness, confusion, sweating, or a fast heartbeat. Patients should be educated on how to recognize and manage hypoglycemia. Always refer to the full product information and discuss all potential risks with your healthcare provider.

Frequently Asked Questions

How long do Ozempic side effects last?

Most side effects of Ozempic are short-term and usually get better over time. They often appear when you first start the medication or after a dose increase. For many people, common side effects like nausea and abdominal pain improve within about three months. However, some serious long-term effects, such as pancreatitis, vision problems, or kidney injury, could potentially last for months or even years after you stop taking Ozempic.

Can Ozempic cause stomach paralysis?

Yes, Ozempic can cause gastrointestinal complications like gastroparesis, which is often called stomach paralysis. This condition involves a significant slowing down or even stopping of stomach emptying. While it is considered a rare side effect, it can lead to persistent nausea, vomiting, and feelings of fullness. This issue is one of the potential long-term Ozempic side effects.

Is there a risk of thyroid cancer with Ozempic?

Ozempic (semaglutide) and similar medications like Wegovy carry a warning about a potential risk of thyroid tumors, including cancer, observed in rodent studies. It is not known if this risk applies to humans. However, you should not use these medications if you or your family have a history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). If you notice a lump in your neck, hoarseness, trouble swallowing, or shortness of breath, tell your doctor right away.

Does Ozempic help protect heart and kidney health?

Ozempic may help protect heart and kidney health, especially in people with type 2 diabetes or obesity. Clinical trials, like the SUSTAIN trials, studied Ozempic for 104 weeks for cardiovascular outcomes. Studies also looked at its effects over 41 months in adults with type 2 diabetes and chronic kidney disease. While it offers benefits, it's important to be aware of potential complications like kidney injury in some individuals.

What are the signs of pancreatitis to watch for?

The signs of pancreatitis, an inflammation of the pancreas, include severe upper stomach pain that may spread to your back. You might also experience nausea or vomiting and a rapid heartbeat. In one 2-year study, 8 people taking injectable Ozempic experienced pancreatitis. If you notice these symptoms, it's important to seek medical attention quickly.
