The chatter about weight-loss medications is all around us these days—it pops up in your Instagram reels, in celebrity gossip magazines, and in your social circles. Even news outlets like National Public Radio are covering it. New weight-loss drugs have indeed reached a new level of popularity. And one, in particular, has been at the forefront of most talk: Wegovy®. 

Wegovy (semaglutide) has been all over the news not only because its results have been remarkable but also because of the nationwide shortages. In May, Novo Nordisk announced on its website that demand continues to exceed the company’s  current supply capacity, and patients may have difficulty filling their Wegovy prescription through September. 

Research suggests it can help patients lose up to 15 percent of their body weight over 68 weeks when combined with diet and exercise. Wegovy is one of two GLP-1s approved by the U.S. Food and Drug Administration (FDA) for weight loss. The other is Saxenda® (liraglutide), which works similarly for chronic weight management in people who have obesity or who have a BMI of 27 or greater with related health issues.

In addition to Wegovy and Saxenda,  Ozempic® (also semaglutide), which is FDA-approved for the treatment of type 2 diabetes, has also shown promise and is often prescribed off-label for weight loss. And to say demand for this drug is high among those looking to drop pounds—whether 10 or 100—would be a major understatement. 

With all the information circulating around, you may have questions about how Wegovy weight loss works and whether it’s right for you. We’re here to help sort through some of the claims and give you up-to-date information on what we know now.

What is Wegovy?

Wegovy, the brand name for semaglutide, is a once-weekly, injectable glucagon-like peptide 1 receptor agonist (GLP-1 RA).* Wegovy is manufactured by Novo Nordisk, which also produces popular diabetes drugs Rybelsus® and Ozempic. Interestingly enough, Novo Nordisk saw the weight loss success Ozempic had in patients with type 2 diabetes. So it began testing higher doses of semaglutide in clinical trials and received FDA approval for Wegovy in June of 2021.

Unlike Ozempic, Wegovy is FDA-approved for weight management in patients with a body mass index (BMI) of 27 or greater who have at least one weight-related condition—like high blood pressure, type 2 diabetes, or high cholesterol—or in patients with a BMI of 30 or greater.   

The medication imitates the GLP-1 hormone your body already makes and helps regulate appetite and slow gastric emptying. It also signals your pancreas to release insulin after eating or when blood sugar is high—ultimately reducing blood sugar levels. Essentially, what Wegovy does is help your gut and brain better communicate to make you feel fuller and help reduce appetite.

How much weight will you lose on Wegovy?

The Wegovy weight loss results are promising. In a double-blind 68-week clinical trial by Novo Nordisk, the manufacturer of Wegovy, 1,961 adults with obesity or overweight took either Wegovy or a placebo in addition to following a reduced-calorie diet plan and increased physical activity. Those on Wegovy lost an average of about 35 pounds, or about 15% of their body weight. Those taking the placebo lost an average of 6 pounds, or roughly 2.5% of their body weight.

How much weight you lose when taking Wegovy for weight loss completely depends on you. You’re wonderfully unique. And although the trial results are encouraging, they depend on factors like biology and behavioral healthy lifestyle changes. Your health care provider should cover all the information you need to make the best choice regarding weight-loss meds to see if Wegovy weight loss is a fit for you.

How quickly does Wegovy weight loss work?

In the 68-week trial, patients taking Wegovy began to lose weight at around four weeks, when doses increased from 0.25mg to 0.50 mg. And they continued to lose weight throughout the trial.

Keep in mind, Wegovy may be touted as a “quick-fix” drug, but that’s not how Wegovy weight loss works—with or without medication. So don't stress if it’s not working right away. It takes dedicated and continual use for results that last. Remember to keep your health care provider in the know about your weight loss and how you’re feeling during the journey. If Wegovy isn’t working for you, they’ll try other medications that may work better.

What’s the Wegovy dosage for weight loss?

The typical Wegovy weight loss dosing begins at 0.25 mg, injected under your skin once a week for four weeks (one month). You’ll use a higher dose every four weeks until you reach a weekly maintenance dose of 2.4 mg. The standard dosing schedule might look like this:

  • Month one: 0.25 mg once a week
  • Month two 0.5 mg once a week
  • Month three: 1 mg once a week
  • Month four: 1.7 mg once a week
  • Month five and beyond: 2.4 mg once a week (maintenance dose)

How long do you take Wegovy for weight loss?

Great question. Obesity is a chronic disease, which means that for many people, medication will need to be taken long-term for sustainable weight loss. Just like other medical conditions like asthma or arthritis, obesity needs to be treated continually. 

One review in the Journal of Investigative Medicine found that those who were given a placebo after 20 weeks of losing weight on semaglutide regained around 13 pounds. Meaning when they stopped using the drug, they didn’t sustain their weight loss. This shows that continual use is needed for ongoing weight management. Not only that, the most common side effects were pretty minor and included things like nausea and constipation—which subsided. And Wegovy has been proven to be well-tolerated by most patients for long-term use.

How does Wegovy work for weight loss?

Wegovy works similarly to other GLP-1 prescription drugs in one of three ways. First, semaglutide mimics the GLP-1 incretin hormone your body already makes that helps control your appetite. Second, it communicates with the pancreas letting the organ know how much insulin to produce after you eat, helping to manage blood sugar levels. And third, it delays gastric emptying, which means it slows digestion, supporting weight loss by promoting the feeling of fullness so you eat less. 

Wegovy works most effectively when used as prescribed in combination with a reduced-calorie diet (which means something different to everyone so chat with your health care professional about healthy meal changes) and increased physical activity.

What are the side effects of Wegovy weight loss?

We mentioned a few of the common side effects, but there are a few others you may potentially experience. Here’s what to be aware of:

  • diarrhea
  • vomiting
  • stomach (abdomen) pain
  • headache
  • tiredness (fatigue)
  • upset stomach
  • dizziness
  • feeling bloated
  • belching
  • gas
  • stomach flu
  • heartburn
  • runny nose
  • sore throat

And, although rare, you may experience more severe side effects. They include:

  • inflammation of your pancreas (pancreatitis)
  • gallbladder problems
  • increased risk of low blood sugar (hypoglycemia) in patients with type 2 diabetes, especially those who also take medicines for type 2 diabetes, such as sulfonylureas or insulin.
  • kidney problems (kidney failure)
  • serious allergic reactions
  • change in vision in people with type 2 diabetes
  • increased heart rate
  • depression or thoughts of suicide
  • possible thyroid tumors, including cancer

Wegovy also comes with a black box warning. You shouldn’t take it if you or your family have a history of a thyroid cancer called medullary thyroid carcinoma (MTC) or if you have an endocrine system condition called Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). 

Before taking Wegovy for weight loss, you’ll receive all the prescribing information from your healthcare provider.  And you’ll be advised about any possible interactions with other medications, over-the-counter or prescription drugs, or supplements you may be taking or how the drug may impact other health issues.

How do you use Wegovy?

Here’s a helpful step-by-step on what to expect after you’ve been prescribed Wegovy. When you fill your prescription for Wegovy, you’ll get your four-week supply of four single-use pens prefilled with your prescribed dose. There’s a tiny, hidden needle at the tip of each pen, which is how you’ll inject yourself. 

The weekly injection is inserted in your upper arm, upper thigh, or abdomen (stomach), and the manufacturer recommends rotating where you inject yourself to avoid irritation at the injection site. You’ll use one pen per week, and do your best to make sure you inject yourself on the same day each week.

Novo Nordisk also recommends keeping your Wegovy injection pens in the fridge at 36–46º, but they’ll still be okay to use if you keep them between 46–86º for up to 28 days.

Medication preparation

  1. Wash your hands before picking up your Wegovy pen. 
  2. Make sure the new pen shows the correct prescribed medication and dose and that it’s not past its expiration date. 
  3. Next, pull off the pen’s cap. 
  4. Through the pen window, look at the medication to make sure it’s clear and colorless. If it has any debris or particles in it, don’t use the medication; contact your pharmacy and your provider to see if you need a new pen. 
  5. Once you’ve determined the medication is clear, colorless, and particle-free, you can choose an injection site in either your stomach, thigh, or upper arm. 

Once you've decided on an injection site, it’s time to give yourself the Wegovy shot.

How to inject Wegovy

  1. Clean the selected area on your abdomen, thigh, or upper arm with an alcohol wipe. 
  2. Hold the pen in one hand while you pinch the skin with the other hand. Then press the pen firmly against your skin and hold down the button. 
  3. You will hear a click when you start the injection, and the yellow bar on the pen should start moving. If the bar does not start moving, press the pen more firmly against the skin.
  4. Keep holding the button down for 10 seconds. You’ll hear a second click to let you know the injection is still going. Once you hear the second click, keep holding the button down until the yellow bar has stopped moving. 
  5. The yellow bar will stop moving right before the end of the window. Once the yellow bar has stopped, you can slowly remove the pen from your skin. Don’t remove the pen until the yellow bar has stopped moving.

As a note, you can watch a video about how to administer your Wegovy dose here if you’d like a play-by-play on how to do it. After you’ve given yourself the dose, throw the used pen away in a sharps container or a heavy-duty plastic container with a screw-on lid. (Novo Nordisk will provide a free sharps container to patients using Wegovy through NovoCare.) Because the Wegovy pen contains a needle, it’s important not to throw it into your regular trash.

How much does Wegovy cost?

As of May 2023, the list price for Wegovy is $1,349.02/package for a 28-day supply. But, depending on your insurance coverage, you may end up paying way less. 

Novo Nordisk has a Savings Offer where you can pay as little as $0 per 28-day supply but there are terms and conditions for eligibility and you must have commercial insurance to qualify. Before you’re prescribed Wegovy, check with your health insurance to see if it’s covered and what your out-of-pocket expense may be. You can also refer to Novo Nordisk’s patient support network, NovoCare, to get a cost estimate for Wegovy.
