Frequently asked questions

  1. Does Wegovy burn fat? Wegovy (semaglutide) is a medication that helps with weight loss by reducing appetite and increasing feelings of fullness. It works by mimicking the activity of a naturally occurring hormone in the body called glucagon-like peptide-1 (GLP-1). While it doesn't directly "burn" fat, it can lead to weight loss, which may include loss of body fat.
  2. Can Wegovy make you tired? Fatigue is a known side effect of Wegovy, which may occur in some individuals who take the medication. It is important to discuss any side effects you experience with your healthcare provider, who can help determine if the benefits of the medication outweigh the risks.
  3. Who should not take Wegovy? Wegovy is not recommended for people with a personal or family history of medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia syndrome type 2 (MEN 2). It is also not recommended for people with a history of severe gastrointestinal disease, such as gastroparesis or inflammatory bowel disease. People who are allergic to semaglutide or any of the ingredients in Wegovy should not take this medication.
  4. How long can you take Wegovy? Wegovy is typically used as a long-term treatment for weight management. The duration of treatment may vary depending on individual needs and goals. It is important to discuss with your healthcare provider about how long you should take Wegovy and any potential risks or benefits associated with continued use.
  5. Can you drink wine on Wegovy? While there are no specific interactions between alcohol and Wegovy, it is generally recommended to limit alcohol consumption when trying to lose weight. Alcohol contains empty calories and can hinder weight loss efforts. It is important to discuss alcohol use with your healthcare provider, who can provide individualized recommendations based on your health status and goals.
  6. How does Wegovy make you feel? Wegovy may cause some side effects, including nausea, vomiting, diarrhea, and decreased appetite. However, it may also lead to feelings of fullness and increased energy levels due to weight loss.
  7. Are Wegovy and Ozempic the same? Wegovy (semaglutide) and Ozempic (also semaglutide) are both medications that work by mimicking the activity of GLP-1 in the body, but they are approved for different uses. Wegovy is approved for long-term weight management, while Ozempic is approved for the treatment of type 2 diabetes.
  8. Do you keep Wegovy in the fridge? Wegovy should be stored in the refrigerator at a temperature between 36°F to 46°F (2°C to 8°C) until the expiration date on the label. Once the medication is opened, it can be stored at room temperature (up to 86°F or 30°C) for up to 56 days.
  9. What happens when you stop Wegovy? When Wegovy is stopped, appetite may increase and weight loss may plateau or reverse. It is important to work with your healthcare provider to develop a plan for gradually stopping Wegovy, as sudden discontinuation may lead to rebound weight gain.
  10. What time of day should I take Wegovy? Wegovy is typically injected once a week at any time of day, with or without food. It is important to follow the dosing instructions provided by your healthcare provider.
  11. Do you gain weight back after Ozempic? Ozempic is a medication used to treat type 2 diabetes, and weight loss is a potential side effect of the medication. However, weight regain may occur after discontinuing the medication or if blood sugar levels are not well-controlled.
  12. What time of day should I take Wegovy? Wegovy should be injected once a week at any time of the day, with or without food. It is important to take it on the same day and time every week to maintain consistency and achieve the best results.
  13. Do you gain weight back after Ozempic? If an individual stops taking Ozempic or any other weight loss medication, it is possible to regain weight if they return to their previous eating habits and lifestyle. However, maintaining a healthy diet and regular exercise routine can help prevent weight gain.
  14. Does it matter where you inject Wegovy? Wegovy can be injected in the abdomen, thigh, or upper arm. The injection site should be rotated each week to reduce the risk of skin reactions or changes at the injection site.
  15. How quickly do you lose weight on Wegovy? Clinical trials have shown that individuals taking Wegovy can lose an average of 15% of their body weight within the first year of treatment. However, weight loss can vary from person to person, and it may take several weeks to see significant results.
  16. Can Wegovy be stored at room temperature? Wegovy should be stored in a refrigerator at a temperature between 2-8°C (36-46°F). However, it can be kept at room temperature (up to 30°C or 86°F) for a maximum of 4 weeks. After 4 weeks, it should be discarded and a new pen should be used.
  17. Can you take Wegovy and metformin together? Wegovy can be taken with metformin, a medication commonly used to treat type 2 diabetes. However, it is important to consult with a healthcare provider before combining medications to ensure they are safe and effective together.
  18. How much weight can you lose in a week on Wegovy? The amount of weight loss on Wegovy can vary from person to person and depends on several factors, such as diet, exercise, and overall health. In clinical trials, individuals taking Wegovy lost an average of 2-3 pounds per week.
  19. What is the difference between Wegovy and Saxenda? Wegovy and Saxenda are both medications used to treat obesity and promote weight loss. However, they contain different active ingredients and have different dosing regimens.
