Key takeaways

  • Wegovy is FDA approved for chronic weight management in adults and in teens 12 and older with obesity (injection), always alongside diet and activity changes.[1]
  • In STEP 1, adults on weekly semaglutide 2.4 mg lost 14.9% of their body weight on average over 68 weeks, compared with 2.4% on placebo.[6]
  • In SELECT, semaglutide lowered the rate of heart attack, stroke or cardiovascular death from 8.0% to 6.5% in adults with heart disease and overweight or obesity.[7]
  • Nausea, diarrhea, vomiting and constipation are the most common side effects; Wegovy has a boxed warning about thyroid C-cell tumors seen in rodents.[1]
  • Self-pay through NovoCare Pharmacy was $349 a month for regular pens and $149 to $299 for pills, checked on 2026-10-06.[11]

In short: Wegovy is Novo Nordisk’s brand of semaglutide for weight. It is FDA approved, together with a reduced-calorie diet and more physical activity, to reduce excess body weight and keep it off long term in adults and teens 12 and older with obesity, and in adults with overweight plus at least one weight-related condition. It is also approved to lower the risk of heart attack, stroke and cardiovascular death in adults with heart disease and obesity or overweight. It comes as a once-weekly injection and, since December 2025, as a once-daily tablet (status checked on the FDA label on 2026-10-06).

This page explains what the official prescribing information says about Wegovy: who it is labeled for, how it is taken in general terms, what the main trials found, the side effects and warnings, and what it costs. It is general information to help you prepare for a conversation with your clinician, not personal medical advice.

What Wegovy is

The active ingredient in Wegovy is semaglutide, a medicine that acts like GLP-1, a hormone the gut releases after eating. Our semaglutide page explains the mechanism in detail; in short, it slows how fast the stomach empties and acts on appetite centers in the brain, so many people feel full sooner and eat less. Semaglutide belongs to the GLP-1 medication class.

The same molecule is sold under other brand names for other uses. Ozempic is semaglutide approved for type 2 diabetes, not for weight management. Wegovy is the semaglutide brand with the weight indication. The two are not interchangeable: the doses, devices and approved uses are different, and the Wegovy label says it should not be used together with other semaglutide products or any other GLP-1 receptor agonist.

FDA status and approved uses

According to Drugs@FDA, the Wegovy injection was first approved for chronic weight management on June 4, 2021. Later approvals added teens 12 and older with obesity (December 23, 2022), cardiovascular risk reduction in adults with established heart disease and obesity or overweight (March 8, 2024), and, under the FDA’s accelerated approval pathway, the treatment of noncirrhotic MASH (a fatty liver disease) with moderate to advanced liver scarring in adults (August 15, 2025). Accelerated approval means continued approval for MASH may depend on confirmatory results.

Wegovy tablets were approved on December 22, 2025 for adults only, for weight reduction and maintenance and for cardiovascular risk reduction. The tablets are not approved for teens or for MASH. Our Wegovy pill page covers the tablet in detail.

Who it is labeled for

The label describes the population in clinical terms: adults with obesity, adults with overweight in the presence of at least one weight-related comorbid condition, and pediatric patients 12 and older with obesity (injection only). It is always used together with a reduced-calorie diet and increased physical activity. Clinicians usually define obesity and overweight with BMI; the NIH describes weight-management medicines as generally considered for adults with a BMI of 30 or more, or 27 or more with a weight-related condition such as high blood pressure or type 2 diabetes. Whether Wegovy fits a particular person is a decision for that person and their clinician. Our BMI calculator can show where you stand, but it is not a diagnosis.

How it is taken, in general

The injection is given under the skin once a week. The label describes starting at a low dose and stepping up every four weeks over about four months, which gives the stomach time to adjust and reduces nausea. The label lists maintenance options and, in its current version, also a higher-strength Wegovy HD pen. The tablet is taken once a day in the morning on an empty stomach with a small amount of water, then waiting at least 30 minutes before eating, drinking or taking other oral medicines. Your prescriber decides the dose, the pace of increases and what to do about a missed dose; never change these on your own.

What the studies showed

In STEP 1, published in the New England Journal of Medicine in 2021, 1,961 adults without diabetes received weekly semaglutide 2.4 mg or placebo for 68 weeks, both with lifestyle support. Average weight change was -14.9% with semaglutide and -2.4% with placebo, and 86.4% of the semaglutide group lost 5% or more of their weight. Averages hide a wide range: some people lose much more, some much less.

In SELECT, 17,604 adults aged 45 or older with established cardiovascular disease and a BMI of 27 or more, but no diabetes, were followed for an average of about 40 months. A major cardiovascular event (cardiovascular death, nonfatal heart attack or nonfatal stroke) occurred in 6.5% of the semaglutide group and 8.0% of the placebo group, a 20% relative reduction. This trial is the basis for the cardiovascular indication.

STEP 4 looked at what happens when the medicine stops: people who switched to placebo after 20 weeks regained weight (+6.9% over the next 48 weeks), while those who continued kept losing (-7.9%). In the STEP 1 extension, participants had regained about two thirds of their earlier loss one year after stopping. Our guide to life after a GLP-1 covers what helps.

Side effects

Digestive side effects are the most common, especially while the dose is increasing. In the label’s pooled adult weight trials of the 2.4 mg injection, nausea was reported by 44% of people on Wegovy versus 16% on placebo, diarrhea by 30% versus 16%, vomiting by 24% versus 6%, constipation by 24% versus 11% and abdominal pain by 20% versus 10%. About 6.8% of people stopped Wegovy because of side effects, compared with 3.2% on placebo. Headache, fatigue, dizziness, bloating, burping, reflux and hair loss are also listed.

The label’s warnings cover acute pancreatitis, gallbladder problems, low blood sugar when combined with insulin or sulfonylureas, kidney injury from dehydration, severe stomach and bowel reactions, allergic reactions, diabetic eye complications in people with type 2 diabetes, a faster heart rate, and the risk of inhaling stomach contents during anesthesia or deep sedation, so tell any surgical team you take it. See GLP-1 side effects for how these are recognized and managed, and the dedicated Wegovy side effects page.

Boxed warning and who should not use it

Wegovy carries a boxed warning, the FDA’s most prominent warning: semaglutide caused thyroid C-cell tumors in rodents, and it is not known whether it causes these tumors, including medullary thyroid carcinoma (MTC), in humans. Wegovy should not be used by anyone with a personal or family history of MTC or with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2), or by anyone who has had a serious allergic reaction to semaglutide. The label tells patients to report a lump or swelling in the neck, trouble swallowing, hoarseness or shortness of breath.

Pregnancy and breastfeeding

The label states that weight loss offers no benefit during pregnancy and may cause fetal harm, and that Wegovy should be stopped when a pregnancy is recognized when it is used for weight or heart protection. Anyone planning a pregnancy, pregnant or breastfeeding should talk with their clinician before starting or continuing it.

Cost, insurance and savings

Prices checked on 2026-10-06 on Novo Nordisk’s NovoCare site: the list price is $1,349.02 per package for the pen, the HD pen and the pill. Through NovoCare Pharmacy, self-pay is $349 a month for the regular pen strengths and $399 a month for Wegovy HD, with an introductory $199 a month for the first two fills of the two lowest strengths for new patients (through December 31, 2026). Pills are $149 to $299 a month depending on strength. People with commercial insurance that covers Wegovy may pay as little as $25 a month with the savings offer; government beneficiaries are excluded. Novo Nordisk has announced a lower list price of $675 a month from January 1, 2027. Medicare’s temporary GLP-1 Bridge program (July 2026 to December 2027) includes Wegovy for weight management with a $50 copay for people who meet its criteria. The full breakdown is on our Wegovy cost page.

Compounded and counterfeit products

Compounded “semaglutide” is not Wegovy and is not FDA approved. The FDA declared the semaglutide shortage resolved on February 21, 2025, and has reported adverse events linked to compounded products, including dosing errors. The FDA has also seized counterfeit semaglutide pens found in the U.S. supply chain. Buy only with a prescription from a state-licensed pharmacy. Read more in compounded GLP-1s.

Alternatives and comparisons

Other FDA-approved options include Zepbound (tirzepatide, a weekly injection) and Foundayo (orforglipron, a daily pill), as well as older pills and the daily injection Saxenda; our medications hub lists them all with their status badges. For a side-by-side view, see Wegovy vs Zepbound.

How it is taken (in general)

Injection: once weekly under the skin of the stomach, thigh or upper arm, any time of day, with or without meals. The label describes a gradual dose increase every 4 weeks to a maintenance dose to reduce stomach side effects. Tablets: once daily in the morning on an empty stomach with up to 4 ounces of water, waiting at least 30 minutes before food, drink or other oral medicines. Follow your prescriber; never change the dose on your own.

This is what the label describes in general, never a personal dose or schedule. Follow your prescriber.

Warnings and who should not use it

Boxed warning

Risk of thyroid C-cell tumors: in rodents, semaglutide causes thyroid C-cell tumors at clinically relevant exposures. It is unknown whether Wegovy causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans. Wegovy is contraindicated in patients with a personal or family history of MTC or in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). Patients should be counseled on the risk and symptoms of thyroid tumors.

Who should not use it (per the label)

  • Personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2)
  • Prior serious hypersensitivity reaction to semaglutide or any of the product components

Interactions, pregnancy and breastfeeding

Drug or classWhat the label says
Other semaglutide products or GLP-1 receptor agonistsUsing them together is not recommended by the label.
Insulin or insulin secretagogues (such as sulfonylureas)Higher risk of low blood sugar; the prescriber may adjust those medicines.
Oral medicationsSemaglutide slows stomach emptying and may affect how other oral medicines are absorbed.

Supplements with reported interactions: Fiber Supplements for Weight Loss: psyllium, glucomannan and more

Pregnancy and breastfeeding

The label states that weight loss offers no benefit to a pregnant patient and may cause fetal harm; Wegovy used for weight reduction or cardiovascular risk reduction should be discontinued when pregnancy is recognized. Animal studies showed harm to the fetus. Discuss pregnancy plans and breastfeeding with the prescriber.

Questions to ask your doctor or pharmacist

  • Based on my health history, what are the possible benefits and risks of Wegovy for me?
  • Do I have any personal or family history that would rule it out, such as thyroid cancer or MEN 2?
  • How should my other medicines, especially diabetes medicines, be adjusted if I start it?
  • Would the injection or the tablet fit my routine better, and how does my insurance treat each?
  • What is our plan for nutrition, strength training and the long term if I stop?

Frequently asked questions

Is Wegovy the same as Ozempic?

Both contain semaglutide, but they are different products with different approvals. Wegovy is approved for chronic weight management and cardiovascular risk reduction in people with obesity or overweight; Ozempic is approved for type 2 diabetes and related heart and kidney outcomes. The doses and devices differ.

How much weight do people lose on Wegovy?

In the STEP 1 trial, the average was 14.9% of starting weight after 68 weeks, compared with 2.4% on placebo, with lifestyle support in both groups. Individual results vary widely.

Is there a Wegovy pill?

Yes. Wegovy tablets were approved on December 22, 2025 for adults, for weight reduction and maintenance and for cardiovascular risk reduction. They are taken once daily on an empty stomach.

What happens if I stop taking Wegovy?

In trials, most people regained a large part of the weight after stopping: in the STEP 1 extension about two thirds of the loss returned within a year. Any change should be planned with the prescriber.

Does insurance cover Wegovy?

Coverage depends on the plan. Some commercial plans cover it, often with prior authorization. Medicare Part D plans may cover it for the cardiovascular indication, and Medicare runs a temporary GLP-1 Bridge for weight management from July 2026 through 2027. Check with your plan.
