Ozempic (semaglutide) injection is a medication used in the treatment of Type 2 diabetes mellitus. Ozempic is in a class of medications called glucagon-like peptide-1 (GLP-1) receptor agonists. GLP-1 receptor agonists work by slowing down how quickly food leaves the stomach and helping the pancreas release insulin in response to high blood sugar levels after a meal.
The Food and Drug Administration (FDA) has approved Ozempic to be used in addition to weight loss, diet, and exercise to improve blood glucose control in individuals with Type 2 diabetes and to reduce the risk of major cardiovascular events in adults with Type 2 diabetes and cardiovascular disease. GLP-1 receptor agonists are not used in the treatment of Type 1 diabetes.
Ozempic may have some serious side effects. In this article, we will review important Ozempic side effects, warnings, and drug interactions.

Common side effects of Ozempic
Similar to other prescription drugs, individuals who use Ozempic may experience some common side effects. If any of these common side effects become bothersome, notify your healthcare provider.
Gastrointestinal symptoms Nausea Vomiting Diarrhea Constipation Eructation ( burping or belching) Abdominal pain Stomach pain Decreased appetite Dyspepsia (indigestion) Abdominal distension Gastroesophageal reflux disease (GERD) Flatulence (gas) Gastritis (inflammation of the lining of the stomach)
Excess weight contributes to worse health outcomes in people with Type 2 diabetes. Weight loss is usually part of treatment recommendations. Medication choices for diabetes are based on how much glucose control is needed, whether a person has heart or kidney disease or other medical conditions, the risk of low blood sugar, cost and access to the medication, possible side effects, and the potential impact on a person’s weight. Compared with some other medications for diabetes, Ozempic has a greater impact on weight loss. In a clinical trial published in the Lancet, when compared to liraglutide and placebo, individuals taking semaglutide lost more weight. As such, Ozempic may be a good choice for individuals with diabetes who would benefit from weight loss.

GLP-1 receptor agonists are associated with gastrointestinal side effects. In clinical trials, more of these side effects occurred as the dose increased. Greater than 5% of individuals experienced nausea, vomiting, diarrhea, abdominal pain, and/or constipation with Ozempic. Over 20% of individuals taking the highest recommended dose of Ozempic reported nausea. Nausea in particular tends to be worse if individuals continue to eat after they feel full. The dose of Ozempic should be increased slowly if these side effects persist.
Retinopathy
When blood sugar levels are elevated for a long time, the extra glucose in the blood can damage the lining of small blood vessels in the retina (the light-sensitive tissue at the back of the eye). When these blood vessels are damaged, changes such as blurred vision and floating spots or streaks may occur. In a clinical trial, 8.2% of individuals who had diabetic retinopathy when starting Ozempic experienced complications. As such, people with a history of diabetic retinopathy should be closely monitored for progression while taking this medication. Everyone with Type 2 diabetes should have a full eye exam every year.
Serious side effects of Ozempic
Some side effects of Ozempic may be serious or life-threatening. Notify a healthcare professional right away if you believe you are experiencing signs or symptoms of any of the adverse events listed below.
Thyroid tumors Hypersensitivity or serious allergic reactions including anaphylaxis (may be evidenced by itchiness; hoarseness ; tightness and swelling in the mouth, throat, neck, and chest (sweating, rapid heart rate, shortness of breath, and dizziness)
Angioedema (swelling of tissues in the face, eyes, and lips)
Acute kidney injury
Worsening of kidney disease
Pancreatitis (inflammation of the pancreas)
Cholelithiasis (gallstones)
Cholecystitis (inflammation of the gallbladder)
Syncope (fainting and loss of consciousness)
Pancreatitis
While Type 2 diabetes does not cause pancreatitis, it is a known risk factor for developing it. This risk is increased by certain lifestyle choices and medications. In glycemic control trials, acute pancreatitis was confirmed in seven patients taking Ozempic. As such, individuals taking Ozempic should be monitored for signs and symptoms of pancreatitis such as nausea, vomiting, and severe abdominal pain that may also be felt in the back. If pancreatitis is suspected, seek medical attention right away. If pancreatitis is diagnosed, do not continue Ozempic.
How long do Ozempic side effects last?
The severity of side effects often depends on how much medication is being taken. Some common side effects may go away with time, after dose adjustments, or once the body is used to a more normal level of glucose. Injection site reactions can be minimized by occasionally changing the location of your injections. More serious side effects such as kidney problems, gallbladder problems, tumors, and anaphylaxis will likely require the medication to be stopped.
