This medication works best combined with lifestyle changes like diet and exercise.

What Is Wegovy, and Is There a Generic?

Semaglutide is a GLP-1 receptor agonist, a class of medication that mimics a natural hormone in your body that controls hunger and blood sugar. Wegovy is the brand name for semaglutide when used for weight management in adults with obesity or overweight. There is no FDA-approved generic of Ozempic or Wegovy in the US. Compounded semaglutide is not a generic or the same as the brand. The semaglutide shortage ended in February 2025, and the FDA has warned telehealth sellers over "same as brand" claims.

This medication works by slowing digestion, reducing appetite signals to your brain, and helping you feel fuller longer. Semaglutide was first approved to treat type 2 diabetes, under the brand name Ozempic. Wegovy comes as a weekly injection (2.4 mg, or 7.2 mg as Wegovy HD) and as a daily pill. Treatment starts at a low dose and increases gradually over 16 to 20 weeks.

Doctors prescribe Wegovy for chronic weight management in people with a BMI of 30 or higher, or those with a BMI of 27 or higher plus weight-related health conditions like high blood pressure or type 2 diabetes. A licensed doctor can evaluate you online for Wegovy: see how to get Wegovy online, or refill Wegovy online if you already take it. Read how telehealth visits for semaglutide work.

Wegovy Doses: 2.4 mg, 7.2 mg and the Wegovy Pill

Dose Level	Dose	Frequency & Timing
Starting dose (injection)	0.25 mg	Once weekly for weeks 1 to 4
Dose increase 1 (injection)	0.5 mg	Once weekly for weeks 5 to 8
Dose increase 2 (injection)	1 mg	Once weekly for weeks 9 to 12
Dose increase 3 (injection)	1.7 mg	Once weekly for weeks 13 to 16
Maintenance dose (injection)	2.4 mg	Once weekly, ongoing
Wegovy HD (injection)	7.2 mg	Once weekly (higher-dose option)
Wegovy pill	25 mg	Once daily by mouth, in the morning on an empty stomach

Important: Never skip doses or stop taking semaglutide without consulting your doctor. Stopping suddenly may lead to rapid weight regain. If you miss a weekly injection, take it as soon as you remember if your next dose is more than 2 days away. If it's less than 2 days away, skip the missed dose. If you miss 2 or more doses in a row, ask your doctor, because you may need to restart at a lower dose. Always follow your doctor's dosing schedule and discuss any concerns about side effects or adjustments. See the Wegovy dosage guide for how each step works.

Side Effects

Most people tolerate semaglutide well, especially as their body adjusts. Side effects tend to be mild and temporary, though it's important to know what to expect.

Common Side Effects

Nausea: Often the most reported side effect, especially when starting or increasing doses. Usually improves within a few days to weeks as your body adapts.
Vomiting: May occur alongside nausea, typically mild and temporary. Eating smaller, lighter meals can help reduce this symptom.
Diarrhea or constipation: Digestive changes are common as semaglutide slows stomach emptying. Stay hydrated and maintain adequate fiber intake.
Decreased appetite: This is the intended effect, but some people find it too strong early on. Appetite naturally normalizes as your body adjusts.
Stomach pain or discomfort: Mild abdominal pain may occur, usually resolving within days to weeks.
Headache: Occasionally reported during the first few weeks of treatment.

Serious Side Effects

Pancreatitis: Severe, persistent stomach pain that radiates to the back may indicate inflammation of the pancreas. This requires immediate medical attention.
Gallbladder problems: Rapid weight loss can increase gallstone risk. Symptoms include severe upper right abdominal pain and yellowing of skin or eyes.
Thyroid concerns: Semaglutide may affect thyroid function. Wegovy isn't for people with a personal or family history of medullary thyroid carcinoma, or with MEN 2.
Severe allergic reaction: These are rare. Call 911 or get emergency care for swelling of the face or throat or trouble breathing, and get medical help right away for a rash.
Hypoglycemia: If combined with other diabetes medications, blood sugar may drop too low, causing dizziness, sweating, or confusion.

When to Seek Medical Attention

Contact your doctor if nausea or vomiting is severe, persistent, or prevents you from eating or staying hydrated. Call 911 or get emergency care if you have trouble breathing, swelling of the face or throat, or you faint. Get medical help right away for sudden, severe abdominal pain, yellowing of skin or eyes, or other signs of an allergic reaction.

If you notice unusual changes in mood, vision problems, or signs of high blood sugar (increased thirst, frequent urination), inform your doctor. Regular check-ins help ensure the medication is working safely for you.

Drug Interactions

Semaglutide can interact with other medications, particularly those that affect blood sugar or digestion. Always inform your doctor of all medications, supplements, and herbal products you take.

Insulin and Other Diabetes Medications

Using semaglutide with other medicines that also lower blood sugar increases hypoglycemia risk. Your doctor may need to adjust doses of these medications when starting semaglutide. Read about what to avoid when you're taking semaglutide.

Oral Contraceptives (Birth Control Pills)

Semaglutide slows stomach emptying, which can change how some pills are absorbed. Ask your doctor whether your birth control needs any change while you take Wegovy.

Medications That Slow Stomach Emptying

Drugs like anticholinergics or certain diabetes medications (like GLP-1 agonists) can have additive effects when combined with semaglutide. This may increase nausea or constipation. Your doctor will monitor and adjust if needed.

Warfarin (Blood Thinner)

Rapid weight loss from semaglutide can affect how your body processes warfarin, potentially changing its effectiveness. Your doctor may need to monitor INR levels and adjust warfarin dosing more frequently.

Thyroid Medications

Semaglutide may slow how your body absorbs thyroid medications such as levothyroxine. Ask your doctor whether you need extra thyroid level checks while you take Wegovy.

NSAIDs and Other Pain Relievers

Dehydration from nausea or vomiting combined with NSAIDs increases kidney stress. Use acetaminophen when possible, and stay well-hydrated if using NSAIDs.

No, there is no FDA-approved generic Wegovy. The generic GLP-1 option for weight management is liraglutide: a generic Saxenda, the liraglutide brand for weight management, launched in August 2025. Liraglutide is injected once daily, not weekly.

In the main Wegovy trial (STEP 1), adults without diabetes on 2.4 mg lost 14.9% of their body weight on average over 68 weeks, vs 2.4% on placebo. Results vary with starting weight, diet, exercise, genetics, and how well you tolerate the medication. Weight loss is typically gradual and most noticeable after 12 to 16 weeks.

There is no FDA-approved generic semaglutide in the US. Ozempic (type 2 diabetes) and Wegovy (weight management) are brand-name semaglutide; compounded semaglutide is not generic and not FDA-approved.

Yes. Wegovy can be used for weight management in people with type 2 diabetes; Ozempic is the semaglutide brand approved for blood sugar control. Your doctor may need to adjust your other diabetes medication doses to prevent low blood sugar.

Yes. The Wegovy pill (oral semaglutide 25 mg, once daily) was approved for weight management on December 22, 2025. Take it in the morning on an empty stomach with up to 4 ounces of plain water, then wait at least 30 minutes before eating, drinking or taking other oral medicines. Self-pay starts at $149 a month (2026 price). See Foundayo vs. Wegovy pill to compare the two GLP-1 pills for weight management.

Weight often returns within a few months to a year after stopping semaglutide, as appetite signals return to normal. To maintain weight loss long-term, most people need to continue the medication. Discuss your options with your doctor before stopping, and develop a plan to maintain healthy habits.

In SURMOUNT-5, a 72-week head-to-head trial in adults with obesity without diabetes, tirzepatide 10 or 15 mg led to more weight loss than semaglutide 1.7 or 2.4 mg (20.2% vs 13.7% on average). Both act on GLP-1 receptors, and tirzepatide also targets GIP receptors. Tirzepatide vs semaglutide key differences explained goes into more detail, and your doctor can help you decide which fits. If you're weighing a switch, see how semaglutide doses convert to tirzepatide.

The Bottom Line

Wegovy is brand-name semaglutide for chronic weight management, and there is no FDA-approved generic. It comes as a weekly injection (2.4 mg, or 7.2 mg as Wegovy HD) and a daily pill, and the injection dose is raised gradually to limit side effects. Nausea and digestive issues are common early on and typically improve as your body adjusts. It isn't for people with a personal or family history of medullary thyroid carcinoma, or with MEN 2. Cost can be a barrier, but there are lower-cost options, from TrumpRx self-pay to the Wegovy pill and the Medicare GLP-1 Bridge. It works best alongside healthy eating and regular physical activity. Talk with your doctor about whether it fits your health goals.
