Boxed warning
Wegovy has a boxed warningTrusted Source. A boxed warning is the most serious warning from the Food and Drug Administration (FDA). It alerts doctors and patients about drug effects that may be dangerous.
Risk of thyroid cancer. Semaglutide, the active drug* in Wegovy, increased the risk of cancerous thyroid tumors in animal studies. It isn’t known whether this risk is also increased in humans.
Symptoms of a thyroid tumor may include:
- trouble swallowing
- hoarse voice
- lump or swelling in your neck
- shortness of breath
Due to this risk, doctors usually will not prescribe Wegovy if you have a personal or family history of medullary thyroid carcinoma (a type of thyroid cancer). They also typically won’t prescribe Wegovy if you have multiple endocrine neoplasia syndrome type 2. This is a genetic (inherited) disorder of the endocrine system that may cause thyroid cancer.Wegovy UK,wegovy uk price,wegovy weight loss,buy wegovy uk,wegovy where to buy,buy wegovy online

Call your doctor right away if you notice symptoms of a thyroid tumor while using Wegovy. They’ll examine you and will likely recommend lab tests to evaluate your symptoms. They’ll determine whether it’s safe for you to keep using Wegovy.
Nausea
Nausea was the most common side effect reported in Wegovy’s studies
Nausea may go away with time as you continue using Wegovy. In studies, it was rare for people to stop taking the drug due to nausea.
Injecting too much Wegovy can cause severe nausea. (See “What should be done in case of overdose?” below to learn more.) But when Wegovy is used in its approved dosage, severe nausea isn’t an expected side effect.
What might help
Contact your doctor if you experience nausea that’s bothersome or doesn’t go away during Wegovy treatment. They may suggest a medication to reduce nausea. If your nausea still doesn’t go away, they may recommend that you stop using Wegovy.
Constipation
Constipation is possible with Wegovy treatment. This was among the more common side effects reported by people who took Wegovy in studies. But no one in these studies stopped taking Wegovy due to constipation.
Constipation caused by Wegovy may go away on its own as you continue treatment.
What might help
Contact your doctor if you have constipation while taking Wegovy, especially if it’s bothersome or doesn’t go away. They may recommend medication to relieve your constipation. If this doesn’t help, they might recommend stopping Wegovy treatment.
Allergic reactionSome people may have an allergic reaction to Wegovy. Allergic reactions weren’t reported in studies of Wegovy, but they have occurred since the drug was approved.
Symptoms of a mild allergic reaction can include:

- flushing (temporary warmth, redness, or deepening of skin color)
A more severe allergic reaction is rare but possible. Symptoms of a severe allergic reaction can include swelling under your skin, typically in your eyelids, lips, hands, or feet. They can also include swelling of your tongue, mouth, or throat, which can cause trouble breathing.
Call your doctor right away if you have an allergic reaction to Wegovy.

If you get a Wegovy prescription through Calibrate or Ro Body, we encourage you to tell your doctor. It’s important that your doctor know about all medications you take.
Find answers to some commonly asked questions about Wegovy.
Is Wegovy similar to the diabetes drugs Ozempic, Trulicity, and Victoza? Why isn’t Wegovy also used for diabetes?
Wegovy, Ozempic, Trulicity, and Victoza all belong to the same group of drugs, called glucagon-like peptide-1 (GLP-1) receptor agonists. These drugs work in similar ways, but Wegovy isn’t approved for diabetes treatment.
Wegovy and Ozempic both contain semaglutide as their active drug.* Trulicity contains dulaglutide, and Victoza contains liraglutide.
Ozempic, Trulicity, and Victoza are all approved to treat type 2 diabetes in adults. None of these medications are used for type 1 diabetes.
Wegovy has been found to be effective for weight loss and weight management in certain adults, but it is not approved for diabetes treatment.
If you’d like to know more about how these medications compare, talk with your doctor or pharmacist.
How does Wegovy compare with weight-loss alternatives Saxenda and phentermine?
Wegovy and Saxenda are both GLP-1 receptor agonists. These drugs act like the GLP-1 hormone in the body, which helps regulate your appetite and how many calories you consume. Phentermine is a type of appetite suppressant, meaning it works to reduce your appetite.
Phentermine is used short term for weight loss. Wegovy and Saxenda can be used for long-term weight loss and weight management.
Phentermine is only approved for weight loss and management in certain adults. Saxenda and Wegovy may be prescribed for this use in certain children 12 years and older.
To learn more about how these drugs compare, you can talk with your doctor or pharmacist.
How does Wegovy work? Does it give you energy?
Wegovy works by acting like the GLP-1 hormone. This hormone works in your brain to regulate your appetite. By mimicking the activity of GLP-1, Wegovy can help reduce your appetite and lower the amount of calories you consume. This can lead to weight loss and help with weight management over time.
Wegovy doesn’t give you energy. But losing weight often helps people feel more energetic.
If you’d like to know more about how Wegovy works, talk with your doctor or pharmacist.
Do Wegovy pens need to be refrigerated?
Yes, Wegovy pens should be refrigerated at a temperature of 36°F–46°F (2°C–8°C).
If needed, you can store Wegovy pens at 46°F–86°F (8°C–30°C) for up to 28 days. However, the pens cannot be refrigerated again after they are stored at room temperature.
Do not freeze Wegovy pens. Keep the pens in the original carton to protect them from light until you’re ready to inject a dose.
Talk with your pharmacist if you have more questions about handling and storing Wegovy pens.
Is Wegovy a controlled substance?
No, Wegovy isn’t a controlled substance.
Certain other weight loss drugs, such as phentermine, are controlled substances. This means there are additional rules for how the drug can be prescribed and used. But this doesn’t apply to Wegovy.
Your doctor or pharmacist can tell you more about controlled substances.
You may wonder how Wegovy compares with Ozempic. These medications contain the same active drugs,* but have different approved uses.

- sulfonylureas, like glipizide (Glucotrol XL) and glimepiride (Amaryl)

Boxed warning
Wegovy has a boxed warningTrusted Source about the possible risk of thyroid cancer. A boxed warning is the most serious warning from the Food and Drug Administration (FDA) about drug effects that may be dangerous. See “What are Wegovy’s side effects?” above for details.
Other warnings
Wegovy may not be right for you if you have certain medical conditions or other factors that affect your health. Talk with your doctor about your health history before you take Wegovy. Factors to consider include those in the list below.
- Kidney problems. Wegovy can rarely cause kidney problems, including sudden kidney failure. Your risk of this side effect may be higher if you already have kidney problems, such as chronic kidney disease. Your doctor can help determine whether Wegovy is safe for you to use if you have kidney problems.
- Pancreas problems. Sudden pancreatitis (swelling and damage in your pancreas) is a possible side effect of Wegovy. The drug wasn’t studied in people with a history of pancreatitis. So, it’s not known whether these people can safely use Wegovy. Your doctor can help determine whether Wegovy is safe for you.
- Type 2 diabetes or diabetic retinopathy. If you have type 2 diabetes, taking Wegovy could cause diabetic retinopathy. And if you already have diabetic retinopathy, taking Wegovy could make it worse. Talk with your doctor to help determine whether treatment with Wegovy is safe for you. They may want to check your eye health before prescribing the drug to you.
- History of suicidal thoughts or behaviors. Suicidal thoughts or behaviors have been rarely reported in studies of other weight loss drugs. These side effects weren’t reported in Wegovy’s studies. However, there’s still a risk that suicidal thoughts or behaviors could occur in someone with a history of this. Due to this risk, doctors typically won’t prescribe Wegovy if you’ve experienced suicidal thoughts or actions in the past.
- Allergic reaction. If you’ve had an allergic reaction to Wegovy or any of its ingredients, your doctor will likely not prescribe Wegovy. Ask your doctor what other medications are better options for you.
