Key takeaways
  • The main symptom of pancreatitis on Ozempic® (semaglutide) is severe pain in the upper belly that will not go away and may spread to your back, with or without vomiting. Fever and a fast heartbeat can also occur.
  • Pancreatitis on Ozempic® is uncommon. In the label's diabetes trials, it occurred at 0.3 cases per 100 patient-years, vs 0.2 on comparison drugs. Large studies have not shown that Ozempic® raises the overall risk.
  • Normal Ozempic® stomach side effects, like nausea, are usually mild to moderate and most common after a dose increase. Belly pain that is severe, constant or spreads to your back is not a normal side effect.
  • If you think you have pancreatitis, stop Ozempic® and call your provider right away, as the label says. For severe belly pain that will not go away, call 911 or go to the nearest ER.

Belly pain on a weekly diabetes shot can be worrying, because stomach upset is common and usually mild. Knowing the Ozempic® pancreatitis symptoms helps you spot the uncommon times it is something more serious.

In this guide, "Ozempic®" means the once-weekly semaglutide injection, which the FDA approved for type 2 diabetes, not for weight loss [13]. It is also approved to lower heart and kidney risks in some people with type 2 diabetes. We use the current label, revised May 2026, plus large trials and medical guidelines.

Read on to learn the warning signs, how to tell them from normal side effects, how common pancreatitis is, and what to do.

Ozempic® pancreatitis symptoms: what are the warning signs?

The main symptom of pancreatitis on Ozempic® (semaglutide) is severe pain in your upper belly that will not go away [13, 1]. The pain can shift to the left or right side and may spread to your back, with or without vomiting.

Acute pancreatitis is sudden swelling and inflammation of the pancreas, an organ behind the stomach that makes insulin and digestive enzymes [1]. People with acute pancreatitis usually look and feel very sick, says the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) [8].

The Ozempic® Medication Guide uses these words: "severe pain in your stomach area (abdomen) that will not go away, with or without vomiting" [13].

Pancreatitis pain on Ozempic® feels severe and steady, not like mild cramps or gas. The American College of Gastroenterology (ACG) says the pain is usually constant and severe, though it can vary[19]. Pain that is dull, crampy or low in the belly does not fit acute pancreatitis [19].

Watch for these signs of acute pancreatitis (sudden inflammation of the pancreas) while you take Ozempic®:

  • Where and how it hurts: acute pancreatitis pain sits in the upper middle, upper left or upper right belly. It may spread to your back or below your left shoulder blade. It is often sharp, dull, or boring and gradually intensifies into a constant and more severe pain, often lasting several days [1, 13].
  • Nausea ,vomiting and loss of appetite: they may or may not come with the pain [13].
  • Fever: people with acute pancreatitis often have a fever [1, 8].
  • Fast heartbeat (tachycardia): your heart may beat faster than usual [8].
  • Swollen or tender belly: your belly may look swollen or hurt when touched [8].
  • Pain that is worse after eating or lying flat: at first, pain may get worse within minutes of eating, especially fatty food. Lying flat on your back may also make it worse [1].
  • Sweating: people with acute pancreatitis often sweat and look ill [1].

Only a healthcare provider can confirm pancreatitis, using blood tests and sometimes a scan [19].

Normal Ozempic® stomach pain or pancreatitis: how can you tell?

Belly pain and other stomach upset are common, normal Ozempic® side effects on the label, usually mild to moderate and most frequent after a dose increase [13, 17]. Pancreatitis pain is severe, constant and often spreads to your back [13, 1, 19]. A gallbladder problem, a separate warning on the same label, can look similar.

Ozempic® stomach side effects have no set length on the label. A 2021 review by Smits and Van Raalte found they mostly occur in the first 8 to 12 weeks of treatment and then fade [17]. In label trials, most reports of nausea, vomiting and diarrhea came while the dose was being raised [13].

Sources: Ozempic® Prescribing Information (revised May 2026) and Medication Guide (revised January 2025) [13]; MedlinePlus (2025) [1]; NIDDK (2017) [8]; Xie et al. (2026) [20]; Wegovy® Prescribing Information (2026) [15]. Most side effect rates come from 2 placebo-controlled trials (placebo 262, 0.5 mg 260, 1 mg 261 people).

Ozempic® slows how fast food leaves your stomach (delayed gastric emptying), the label says [13]. In label trials, any stomach side effect affected 32.7% (0.5 mg) and 36.4% (1 mg) of people, vs 15.3% on placebo. Only 3.1% (0.5 mg) and 3.8% (1 mg) stopped treatment because of them, vs 0.4% on placebo [13].

On Ozempic®, the difference between pancreatitis and gas or indigestion is the pain: pancreatitis pain is severe and constant and can last for days [1]. Indigestion (dyspepsia) and burping are listed side effects on the label [13].

Upper belly pain on Ozempic® can also come from the gallbladder, especially if it is on the right side and comes with fever, yellow skin or eyes (jaundice) or clay-colored stools [13]. Our guide to GLP-1 side effects covers gallbladder problems in more detail.

What should you do if you think you have pancreatitis on Ozempic®?

If you think you have pancreatitis on Ozempic®, stop taking it and get medical care right away [13]. Acute pancreatitis needs tests and often a hospital stay [1].

  • Stop using Ozempic®. The label says to stop the medicine if pancreatitis is suspected, so do not take your next weekly shot until a provider checks you [13].
  • Get care right away. Call your healthcare provider right away [13]. If the pain is severe and will not go away, call 911 or go to the nearest ER.
  • Tell the ER team you take Ozempic® (semaglutide). Share your dose, the day of your last shot and any other diabetes medicines you take. This matters if you need a procedure with anesthesia or sedation, because Ozempic® slows stomach emptying [13].
  • Expect blood tests and sometimes a scan. Doctors check lipase, a pancreas enzyme that is a more specific sign of pancreatitis than amylase [1]. An ultrasound of the belly is usually done to look for gallstones or stones in the bile duct, the most common cause [19] If a stone may be stuck in the bile duct, an MRI scan of the bile ducts (MRCP) or an endoscopic ultrasound can check for it, and a procedure called ERCP may be needed to remove it [19]. A CT scan,or MRI of the belly may be done, but is not always needed [1].
  • Report it to the FDA. You or your provider can report the problem to FDA MedWatch at 1-800-FDA-1088 [13].

How is pancreatitis treated, and can you restart Ozempic®?

Acute pancreatitis on Ozempic® is often treated in the hospital with fluids through a vein (IV) and pain medicines, and most cases go away in a week or less [1]. MedlinePlus notes that some cases become life-threatening [1]. The weekly shot is stopped, and your provider decides whether you can restart it; the May 2026 label does not say [13]. Stopping does not clear the medicine away: semaglutide stays in the body for about 5 weeks after the last dose [13].

Acute pancreatitis leads to almost 300,000 hospital stays a year in the US, according to the 2024 ACG guideline [19].

  • Complications: almost 1 in 5 people with acute pancreatitis develop complications, such as tissue death (necrosis) or organ failure [19].
  • Fluids and monitoring:the ACG suggests moderate amounts of IV fluids, preferably lactated Ringer’s solution, given early. People with organ failure are cared for in a monitored bed or the ICU. Antibiotics are not given routinely to prevent infection [19].
  • Finding the cause: doctors look for the trigger, such as gallstones, stones in the bile duct, alcohol or very high triglycerides [19].
  • Eating again: for mild cases, the ACG advises eating again early, within 24 to 48 hours as tolerated, starting with low-fat solid food [19].In more severe cases, feeding through a tube into the stomach or intestine is preferred over IV nutrition [19].
  • If gallstones caused it: after a mild gallstone attack, the ACG advises taking out the gallbladder (cholecystectomy) before you go home [19]. If a stone is blocking the bile duct and causing infection (cholangitis), antibiotics are started right away [22] and ERCP (Endoscopic Retrograde Cholangio-Pancreatography] to remove the stone within 24 hours lowers complications and deaths [19].

Going back on Ozempic® after pancreatitis is a decision for your provider. The current label, revised May 2026, says to stop treatment if pancreatitis is suspected and to start appropriate care [13]. It does not say whether you can restart.

Good to know

Older Ozempic® labels, such as the November 2024 version, said not to restart the medicine if pancreatitis was confirmed [12]. The current label, revised May 2026, no longer includes that line [13].

If you cannot go back on Ozempic®, your prescriber can choose a type 2 diabetes medicine from a different drug class. Examples include SGLT2 inhibitors and sulfonylureas, comparison drugs in the Fang (2025) and Xie (2026) studies [5, 20]. See our guide to other type 2 diabetes treatment options.

Can Ozempic® cause pancreatitis?

Ozempic® can be linked to pancreatitis in uncommon cases: its May 2026 label lists acute pancreatitis as a warning, but studies have not proven a cause [13, 7, 2]. Trial reviews by Masson (2024) and Chiang (2025) found no clear rise in risk [7, 2].

Acute pancreatitis is a listed warning in section 5.2 of the Ozempic® label, under Warnings and Precautions [13]. Cases have been seen in people taking GLP-1 receptor agonists (GLP-1 medicines), the drug class that includes semaglutide.

Pancreatitis on Ozempic® can be fatal in severe cases. The label lists forms with bleeding or tissue death (hemorrhagic or necrotizing pancreatitis), and reports after approval include deaths [13]. Those reports cannot show how often it happens, and in the label's diabetes trials pancreatitis was uncommon.

The FDA-approved Ozempic® label does not say the medicine causes pancreatitis. It says acute pancreatitis "has been observed" in people taking GLP-1 medicines, which is not proof of cause [13]. The ACG guideline adds that medicines are rare causes of acute pancreatitis and are more often blamed by mistake [19].

Good to know

Pancreatitis is not Ozempic®'s boxed warning, the FDA's strongest label warning. The boxed warning is about thyroid C-cell tumors [13].

Pancreatitis is not the same as pancreatic cancer. We cover cancer questions in long-term effects of Ozempic® and Wegovy®.

For what this diabetes medicine treats and how it works, see our Ozempic® (semaglutide) guide.

Why might Ozempic® affect the pancreas?

No one knows for sure why Ozempic® might affect the pancreas. One possible link is gallstones, the leading cause of acute pancreatitis: a 2025 meta-analysis by Chiang found GLP-1 medicines raise gallstone risk [19, 2]. A 2014 lab study by Pyke also found GLP-1 receptors on some pancreas cells [16].

Ozempic® is a diabetes medicine that works partly through the pancreas. Semaglutide acts on GLP-1 receptors and helps the pancreas release insulin when blood sugar is high [13].

A 2014 lab study of human and monkey pancreas tissue found GLP-1 receptors mainly on insulin-making beta cells [16]. Levels were much weaker on acinar cells (the cells that make digestive enzymes). Whether this diabetes medicine affects these cells directly is not known [16, 17].

GLP-1 medicines raise the risk of gallstones, and gallstones are the leading cause of acute pancreatitis [2, 19]. In a 2025 meta-analysis of 55 placebo-controlled trials, gallstones were about 1.5 times as likely as on placebo (RR 1.46, 95% CI 1.09 to 1.97) [2]. That is about 2 more cases per 1,000 people.

Whether pancreatitis on Ozempic® comes from the drug itself or from weight loss is not known. Fast weight loss raises gallstone risk, but the Wegovy® (semaglutide) label says gallbladder problems were more common than on placebo even after accounting for weight loss [15]. Researchers think slower gallbladder emptying may also let sludge and stones form [17].

Researchers have not shown that Ozempic® damages the pancreas over the long term. Most animal studies found no pancreas damage, though a few showed inflammation, according to a 2021 review of semaglutide safety by Smits and Van Raalte [17].

How common is pancreatitis on Ozempic®?

Pancreatitis is uncommon on Ozempic®: in the label's type 2 diabetes trials, it occurred at 0.3 cases per 100 patient-years, vs 0.2 on comparison drugs [13]. That is about 3 in 1,000 people taking it for a year (about 0.3%), vs about 2 in 1,000 on other diabetes medicines. Expert reviewers confirmed each case (adjudication): 7 vs 3 [13].

People with type 2 diabetes already get pancreatitis more often than people without it. A 2009 US insurance study matched 337,067 adults with type 2 diabetes to 337,067 without it, using 1999 to 2005 data. The diabetes group's acute pancreatitis rate was about 2.8 times higher [9].

What do large studies show about Ozempic® and pancreatitis?

As of October 2026, newer studies have not changed the picture on Ozempic® and pancreatitis. Taken together, the evidence does not show that this diabetes medicine raises the overall risk. Two reviews of placebo-controlled trials, by Masson (2024) and Chiang (2025), found no clear increase with semaglutide or with GLP-1 medicines overall [7, 2].

Sources: Ozempic® label [13]; ClinicalTrials.gov [10, 11]; Masson et al. [7]; Chiang et al. [2]; Fang et al. [5]; Xie et al. [20]; Sodhi et al. [18]. Trial rows show serious events reported by investigators on ClinicalTrials.gov under each MedDRA term, not cases confirmed by expert review; adding terms may count one person twice. HR = hazard ratio; CI = confidence interval. Studies differ in design and people, so their numbers are not directly comparable.

SUSTAIN 6 tested Ozempic® for 2 years in people with type 2 diabetes; SELECT tested Wegovy® (semaglutide) in people without diabetes [10, 11]. In both, serious events reported as acute pancreatitis affected fewer than 2 in 1,000 people per group. Counting all pancreatitis terms, rates stayed under 5 in 1,000 and were not higher on semaglutide [10, 11].

In two large US studies of adults with type 2 diabetes, Fang (2025) and Xie (2026), GLP-1 medicines such as Ozempic® did not raise overall pancreatitis risk [5, 20]. The comparison drugs were SGLT2 inhibitors, DPP-4 inhibitors or sulfonylureas.

A 2026 study by Xie followed 333,687 US veterans for a year [20]. Those starting GLP-1 medicines had about 23 more suspected drug-related pancreatitis cases per 100,000 people than those starting sulfonylureas. These cases clustered early, about 4 in 10 in the first 3 months, and were offset by fewer cases caused by alcohol or high triglycerides [20].

A 2023 study by Sodhi, of people using GLP-1 medicines for weight loss, found a higher pancreatitis risk [18]. Its result was very uncertain because there were few cases, and the authors called the events rare.

Case reports and news stories about pancreatitis on Ozempic® each describe what happened to one person, so they cannot show how often it happens. That is why they can make pancreatitis sound more common than it is.

Who is at higher risk, and can you take Ozempic® after pancreatitis?

Gallstones, very high triglycerides, heavy drinking and past pancreatitis raise pancreatitis risk, per the ACG, but the May 2026 Ozempic® label does not bar people with past pancreatitis [19, 13]. If you have had pancreatitis, you and your provider decide together whether to start the weekly shot.

The ACG guideline, drug labels and a 2009 diabetes study point to these pancreatitis risk factors, which also apply to people taking Ozempic®:

  • Gallstones: gallstones are the leading cause of acute pancreatitis, accounting for 40% to 70% of cases [19].
  • Heavy alcohol use: alcohol is the second leading cause, which accounts for 25% to 35% of cases [19].
  • Very high triglycerides (hypertriglyceridemia): triglycerides, a blood fat, above 1,000 mg/dL can cause pancreatitis, in about 5% of cases [19].
  • Past pancreatitis: a repeat attack happens in about 20% to 29% of people after a first attack [19].
  • Fast or large weight loss: rapid weight loss raises the risk of gallstones, per the Wegovy® label [15].
  • Type 2 diabetes: people with type 2 diabetes have a higher starting risk than people without it [9].
  • Obesity: a BMI above 30 is linked to a more severe attack if pancreatitis happens [19].

Past pancreatitis is not a contraindication (a listed reason not to use a medicine) for Ozempic®. The label lists only 2: medullary thyroid cancer or MEN 2 in you or your family, and a serious allergy to semaglutide [13].

The Ozempic® Medication Guide asks you to tell your provider if you "have or have had problems with your pancreas" [13].

Older Ozempic® labels, such as the November 2024 version, said the weekly shot had not been studied in people with past pancreatitis [12]. They suggested other diabetes medicines for these people. The current label, revised May 2026, does not include that statement [13].

One 2024 real-world study looked at adults with type 2 diabetes who had acute pancreatitis before [6]. It suggests GLP-1 medicines were not tied to more repeat attacks. It was published as a short report, and its summary gives no study size or time frame, so the finding is hard to weigh.

How can you lower your pancreatitis risk on Ozempic®?

You can lower your pancreatitis risk on Ozempic® by limiting alcohol and telling your prescriber about gallstones or high triglycerides [1, 13]. These steps come from MedlinePlus, the Medication Guide and the ACG guideline [19]. No step can rule pancreatitis out.

  • Limit alcohol: about 4 to 5 drinks a day for 5 or more years can damage the pancreas, according to MedlinePlus [1]. If alcohol caused a past attack, MedlinePlus says not to drink [1].
  • Don’t smoke: smoking can make acute pancreatitis worse, according to MedlinePlus [1].
  • Share your history before you start: tell your prescriber about past pancreas problems, as the Medication Guide asks [13], and about gallstones, the leading cause of acute pancreatitis [19].
  • Ask about triglycerides: if yours have been very high, ask your prescriber whether to check them. MedlinePlus advises treating problems that lead to high triglycerides [1].
  • Follow the label's slow start: the Ozempic® label says a slow start lowers stomach side effects, but a slow start is not proven to prevent pancreatitis [13]. Treatment starts at 0.25 mg weekly for 4 weeks, then 0.5 mg, with further increases after at least 4 weeks, up to 2 mg. Your prescriber sets your Ozempic® dose schedule.
  • Know the warning signs early: watch closely in the first 3 months, when one 2026 veterans study saw extra suspected cases cluster [20].

Do Wegovy®, Mounjaro® and other GLP-1 medicines carry the same pancreatitis warning?

Yes, Wegovy® (semaglutide), Rybelsus® (semaglutide), Mounjaro® (tirzepatide) and Zepbound® (tirzepatide) carry the same acute pancreatitis warning as Ozempic®, though their label rates are not directly comparable [15, 14, 3, 4]. Each label says to stop treatment if pancreatitis is suspected.

Wegovy® and Rybelsus® contain semaglutide, the same medicine in Ozempic® [15, 14].

Semaglutide also comes as a daily pill called Ozempic® tablets, which shares a label with Rybelsus® and carries the same warning [14].

The Mounjaro® (tirzepatide) label also lists acute pancreatitis as a warning [3]. Mounjaro® and Zepbound® contain tirzepatide, a different medicine that acts on both GIP and GLP-1 receptors [3, 4]. Learn more in our Mounjaro® (tirzepatide) guide.

Ozempic® and Rybelsus® are approved for type 2 diabetes, not for weight loss [13, 14]. Wegovy® and Zepbound® are approved for weight management [15, 4].

Sources: each medicine's FDA Prescribing Information, revision month shown [13, 14, 15, 3, 4]. Rates come from different trials in different people and are not a head-to-head comparison.

Ozempic®, Rybelsus®, Wegovy®, Mounjaro® and Zepbound® all carry an acute pancreatitis warning, but a warning is not proof that a medicine causes pancreatitis [13, 14, 15, 3, 4]. Switching from the weekly shot to another GLP-1 medicine does not remove the warning.

When should you see a healthcare provider about belly pain on Ozempic®?

Call your healthcare provider right away for belly pain on Ozempic® that is severe or will not go away [13]. Get emergency care if the pain is severe and constant.

The Medication Guide says to call your provider for these problems [13]:

  • Nausea, vomiting or diarrhea that does not go away, which can lead to dehydration.
  • Stomach problems that are severe or will not go away.
  • Signs of a gallbladder problem, right away: pain in your upper stomach, yellow skin or eyes, fever or clay-colored stools.
  • Belly pain with shortness of breath.
  • Belly pain with fever or chills and yellow skin or eyes.
  • Any past pancreas problems, including pancreatitis, before you start Ozempic®.

Call 911 or go to the nearest ER if you take Ozempic® and have any of these possible signs of pancreatitis:

  • Severe belly pain that will not go away, with or without vomiting, especially if it spreads to your back. The Ozempic® Medication Guide names this pain as the pancreatitis warning sign [13].
  • Belly pain with a fever and a fast heartbeat.
  • Belly pain with vomiting so often that you cannot keep fluids down.

Bottom line

  • The key Ozempic® pancreatitis symptom is severe, constant upper belly pain that may spread to your back. Mild nausea after a dose increase is a normal side effect.
  • Pancreatitis is a warning on the Ozempic® label, but it is uncommon, and large studies have not shown that the weekly shot raises the overall risk.
  • If you suspect pancreatitis, stop Ozempic® and get care right away; call 911 or go to the nearest ER for severe pain that will not go away.
  • Your provider decides whether you can restart, and Wegovy®, Rybelsus®, Mounjaro® and Zepbound® carry the same warning.

The only way to know if Ozempic® is affecting your pancreas is a provider check, especially for severe upper belly pain that will not go away [13]. Per the ACG guideline, pancreatitis is diagnosed from symptoms plus a blood test or a scan [19]. In placebo-controlled label trials, lipase rose 22% and amylase 13% on average, unlike on placebo [13]. A 2021 safety review notes that a mildly high lipase alone does not mean pancreatitis [17].

What are the three cardinal signs of pancreatitis?

The three cardinal signs of acute pancreatitis, on Ozempic® or not, are typical upper belly pain, high pancreas enzymes and typical scan changes. Doctors diagnose it when 2 of the 3 are present, per the ACG guideline, based on the revised Atlanta criteria [19]. The enzyme sign means a lipase or amylase blood level more than 3 times the upper limit of normal.

What are the early warning signs of pancreatitis?

The earliest warning sign of pancreatitis, on Ozempic® or not, is pain in the upper belly that can start slowly or suddenly [8]. At first, the pain may get worse within minutes after eating or drinking, especially fatty foods [1]. Then it often becomes constant and more severe, lasting for several days. Nausea, vomiting and fever can also occur [8].

What organs is Ozempic® hard on?

The Ozempic® label warns about the pancreas (pancreatitis), gallbladder (gallstones), kidneys (injury from dehydration) and thyroid, among others [13]. Its boxed warning covers thyroid C-cell tumors seen in rodent studies; whether they happen in people is unknown. The label's most common side effects are stomach-related: nausea, vomiting, diarrhea, belly pain and constipation.

Should I stop taking Ozempic® if I have stomach pain?

Not for mild stomach upset: the Ozempic® label does not say to stop for that, and it is common during dose increases [13]. If the pain is severe and will not go away, stop the weekly shot and call your provider right away, as the label says. Also tell your provider about nausea, vomiting or diarrhea that does not go away, because it can lead to dehydration [13].

Is Wegovy® safer than Ozempic® for the pancreas?

No study shows that Wegovy® is safer than Ozempic® for the pancreas [15, 13]. Both contain the same medicine, semaglutide, and both labels carry the same acute pancreatitis warning. Their label rates come from different trials in different people, so they cannot be compared head to head.
