Important Safety Information

What is the most important information I should know about Wegovy®?

Wegovy® may cause serious side effects, including:

  • Possible thyroid tumors, including cancer. Tell your healthcare provider if you get a lump or swelling in your neck, hoarseness, trouble swallowing, or shortness of breath. These may be symptoms of thyroid cancer. In studies with rodents, Wegovy® and medicines that work like Wegovy® caused thyroid tumors, including thyroid cancer. It is not known if Wegovy® will cause thyroid tumors or a type of thyroid cancer called medullary thyroid carcinoma (MTC) in people
  • Do not use Wegovy® if you or any of your family have ever had a type of thyroid cancer called medullary thyroid carcinoma (MTC) or if you have an endocrine system condition called Multiple Endocrine Neoplasia syndrome type 2 (MEN 2)

When you’re taking Wegovy®, you may experience side effects. They can happen to anyone, but not everyone experiences them the same way. Many side effects can be managed, and the first step in managing them is to talk with your health care provider. Once you identify them, you can keep track of what might be aggravating them, like food and other activities.

There are many ways to manage side effects, but there’s no right way for everyone. For example, you may be able to reduce nausea by eating bland, low-fat foods like toast. Or you may find that it helps to stay sitting up after meals. Find what works for you.

Pay attention and keep track

Another known side effect of Wegovy® is belching. Does that mean that any time you belch, it must be a side effect? Not necessarily. Besides, a side effect like belching might not cause you concern. That said, if you’re belching regularly, definitely mention it to your health care provider.

So how can you tell if what you’re feeling is a side effect? It’s not always clear, but one thing is for sure:

If you feel something new, don’t ignore it. It could be a minor annoyance, or it could be a sign of a more serious issue. If you experience anything that bothers you or doesn’t go away, keep track of it and discuss it with your health care provider. And keep in mind that not all possible side effects of Wegovy® are listed below.

One way to keep track:

Use a journal or your phone to make a list of everything you notice, along with the details of how and when. Capture as much specific information as possible. Don’t just tell your health care provider that you had a headache; note when it started, how long it lasted, and how often it has happened.

Managing side effects and moving forward

Listen to your body. Whatever you’re experiencing, tell your health care provider about it. It’s also important to talk to them about what you want out of taking Wegovy®. Think about what’s meaningful to you, both day to day and in the long term. You can work with your health care provider to make progress toward your goals while keeping side effects at a manageable level.

Common side effects of Wegovy® may include nausea, diarrhea, vomiting, constipation, stomach (abdomen) pain, headache, tiredness (fatigue), upset stomach, dizziness, feeling bloated, belching, low blood sugar in people with type 2 diabetes, gas, stomach flu, heartburn, and runny nose or sore throat. Talk to your health care provider about any side effect that bothers you or does not go away. These are not all the possible side effects of Wegovy®.
