What is Ozempic?
Ozempic is the brand name for a medicine called semaglutide. It’s mainly used to help people with type 2 diabetes lower their blood sugar levels. It’s also been found to help with weight loss, which is why some people who don’t have diabetes may take it under medical supervision for that purpose.Ozempic is given as a once-a-week injection under the skin (usually in the stomach, thigh, or upper arm). It comes in a pen-like injector, making it pretty easy to use at home.
How Does Ozempic Work? (Mechanism of Action)
Ozempic works by mimicking a natural hormone in your body called GLP-1 (glucagon-like peptide-1). This hormone is normally released after eating, and it helps to:- Stimulate insulin release when your blood sugar is high
- Lower the amount of sugar released by the liver
- Slow down how fast food leaves your stomach
- Reduce appetite and help with feeling full
Ozempic Generic
The generic name for Ozempic is semaglutide. Right now, there is no generic version of Ozempic available in the U.S. as of 2025, because it’s still under patent protection.
Semaglutide is also sold under other brand names:
- Rybelsus (oral tablet form for diabetes)
- Wegovy (higher dose injection for weight loss)
Ozempic is not available in a pill, but Rybelsus is the pill version of semaglutide.
All of these are made by the same company, Novo Nordisk.

Ozempic Drug Class
Ozempic (semaglutide) belongs to a group of medicines called GLP-1 receptor agonists. That stands for glucagon-like peptide-1 receptor agonist. These drugs copy the effects of a natural hormone in your body that helps control blood sugar, especially after meals. Other drugs in this class include Trulicity (dulaglutide) and Victoza (liraglutide).Ozempic Side effects
Short-Term Side Effects
Most of the short-term side effects of Ozempic are related to the stomach and digestive system. These are more common when you first start taking it or when the dose is increased. Common short-term side effects include:- Nausea
- Vomiting
- Diarrhea
- Constipation
- Stomach pain
- Loss of appetite
Long-Term Side Effects
Some long-term or serious side effects may develop over time, although they are less common. These include:- Pancreatitis (inflammation of the pancreas)
- Gallbladder problems (like gallstones)
- Kidney problems, especially if you become dehydrated
- Thyroid tumors – in animal studies, semaglutide caused thyroid tumors, but it’s not clear if this happens in humans. Still, people with a history of certain thyroid cancers should avoid it.
- Hypoglycemia (low blood sugar) – especially when used with insulin or other diabetes medications
Ozempic Side Effects in Females
Women taking Ozempic can experience the same side effects as anyone else, but some may feel them a bit differently. Common side effects in females include:- Nausea and vomiting
- Constipation
- Bloating
- Stomach cramps
- Fatigue
- Hair thinning or hair loss (reported by some, though not officially listed)
- Menstrual changes (rare, but some women report irregular periods)
Ozempic and Pregnancy
Ozempic is not recommended during pregnancy. It hasn’t been studied enough in pregnant women, and animal studies suggest it could harm the baby. If you’re planning to get pregnant, doctors usually recommend stopping Ozempic at least 2 months before trying to conceive, since it stays in your body for a while after you stop using it.If you become pregnant while taking Ozempic, you should let your doctor know right away. They will likely stop the medication and may suggest a safer alternative to help manage blood sugar during pregnancy.
Ozempic and Breastfeeding
Ozempic is not recommended during breastfeeding. That’s because we don’t have enough studies to know if semaglutide passes into breast milk or if it could harm a nursing baby. If you’re breastfeeding or planning to, talk to your doctor. They may suggest another treatment until you’re done nursing.Ozempic Contraindications
Who Should NOT Take Ozempic?
Ozempic is not safe for everyone. You should not take it if you:- Have a personal or family history of medullary thyroid cancer
- Have Multiple Endocrine Neoplasia syndrome type 2 (MEN 2)
- Are pregnant or breastfeeding
- Have serious stomach or intestinal issues, such as gastroparesis (a condition where the stomach empties too slowly)
- Are allergic to semaglutide or any ingredients in the pen
Ozempic and the Gallbladder
There’s a possible link between Ozempic and gallbladder problems, such as gallstones or inflammation of the gallbladder (cholecystitis). Some people using Ozempic have developed these issues, especially if they lose weight quickly. Symptoms might include:- Upper right belly pain
- Nausea or vomiting
- Yellowing of the skin or eyes (jaundice)
Ozempic and the Liver
Ozempic is not known to cause major liver damage, but like any medication, it can affect liver function in rare cases. It may slightly lower liver enzyme levels in people with fatty liver disease, which can actually be a good thing. But if you have existing liver problems, you should still be cautious and have your doctor monitor your liver function while on it.Ozempic and Zofran
Zofran (ondansetron) is an anti-nausea medication often used to help people taking Ozempic. Since Ozempic can cause nausea or vomiting, especially when you first start, doctors may prescribe Zofran to make it more tolerable.These two drugs can be used together, but only under medical guidance. Zofran is usually taken as needed, not daily, and it’s important to watch for side effects like constipation or headaches when using it regularly.
Ozempic and Joint Pain
Some people report joint pain while taking Ozempic, although it’s not one of the most common side effects. The pain can vary from mild to more uncomfortable. If you start having unexplained or lasting joint pain while using Ozempic, mention it to your doctor—it could be related or something else.Is Ozempic Linked to Cancer?
This is a tricky one. In animal studies, semaglutide (the active ingredient in Ozempic) caused thyroid tumors, including a rare type called medullary thyroid carcinoma (MTC). But it’s not clear if this happens in humans.Because of this, Ozempic has a warning about the potential risk, and it should not be used by people with a personal or family history of MTC or MEN2 (a rare genetic condition). As for other types of cancer, there’s no strong evidence showing a direct link between Ozempic and cancer, but more research is still ongoing.
Ozempic Dosing for Weight Loss
Ozempic is not officially FDA-approved for weight loss (that’s what Wegovy is for), but doctors sometimes prescribe it off-label to help people lose weight. The usual dosing schedule starts low to help prevent side effects:- Start with 0.25 mg once weekly for 4 weeks
- Increase to 0.5 mg once weekly
- If needed, your doctor may increase to 1 mg or 2 mg weekly
Ozempic Face
“Ozempic face” is a term people use to describe facial changes after weight loss on Ozempic. Since the medication helps reduce body fat, some people lose fat from the face too, which can make them look older or more gaunt. The skin might appear looser or more hollow in the cheeks. This effect isn’t harmful, but it can be emotionally noticeable. Some people choose to use fillers or skin-tightening treatments if it bothers them.Ozempic Butt
Similar to “Ozempic face,” “Ozempic butt” refers to fat loss in the buttocks area. This can lead to a flatter appearance or loose skin, especially if someone loses a lot of weight quickly. Again, it’s not dangerous—just a physical change from fat loss. Strength training and eating enough protein during weight loss can help reduce this kind of muscle and fat loss.Ozempic and Constipation
Constipation is a very common side effect of Ozempic. It happens because the medication slows down how quickly food moves through your digestive system. Tips to manage constipation on Ozempic:- Drink more water
- Eat fiber-rich foods (like fruits, vegetables, and whole grains)
- Take a mild stool softener or fiber supplement if needed (ask your doctor first)
- Stay physically active
Ozempic and Exercise
Ozempic can be a helpful tool alongside a healthy lifestyle, including exercise. In fact, regular exercise can boost the benefits of Ozempic, helping with both blood sugar control and weight loss. But you should be careful not to overdo it, especially when starting Ozempic, since nausea and low energy are common in the beginning.Start slow, stay hydrated, and listen to your body.
