Wegovy Uses


Wegovy Uses

Wegovy helps with weight loss when taken along with a lower-calorie diet and increased physical activity. It can also reduce the risk of major adverse cardiovascular events such as heart attack, stroke, and death in overweight and obese individuals with cardiovascular disease. 

There may be other uses of Wegovy—your doctor or pharmacist can give you further drug information.

Wegovy Mechanism of Action

Wegovy (semaglutide) is almost identical to a natural hormone in the human body called glucagon-like-peptide-1 (GLP-1). GLP-1 helps to regulate appetite and food intake. Wegovy (semaglutide) binds to and activates GLP-1 receptors in the brain, slows movement of food through the stomach, suppresses appetite, and thereby leads to reduced caloric intake and weight loss. It is unclear how Wegovy lowers the risk of heart attack, stroke, and cardiovascular death in people with established cardiovascular disease.

Wegovy Doses

Wegovy comes in a single-dose, pre-filled, disposable pen for subcutaneous injection (under the skin of the upper arm, abdomen, or thigh) once a week. You should take a Wegovy injection on the same day of the week every week. You can take it at any time of the day without regard to meals. 

The dosage strengths of Wegovy pens are 0.25 mg/0.5 mL, 0.5 mg/0.5 mL, 1 mg/0.5 mL, 1.7 mg/0.75 mL, and 2.4 mg/0.75 mL. The dose of Wegovy is gradually increased as follows:

  • Weeks 1 through 4: 0.25 mg once weekly
  • Weeks 5 through 8: 0.5 mg once weekly
  • Weeks 9 through 12: 1 mg once weekly
  • Weeks 13 through 16: 1.7 mg once weekly
  • Week 17 onwards: 1.7 mg or 2.4 mg once weekly (maintenance dose)

Wegovy Directions


How To Use Wegovy

Wegovy (semaglutide) comes as a liquid solution in a prefilled single-use dosing pen for injection subcutaneously (under the skin). It can be injected at any time of the day, with or without food. However, you should inject Wegovy on the same day of the week every week. If you want to change the day of the week that you inject Wegovy, you can do so as long as at least 48 hours (2 days) have passed since your last injection. 

Read the prescription label carefully and follow your doctor’s dosing instructions. Use Wegovy exactly as prescribed. Do not change the dose or dosing frequency without your doctor’s approval.

Your doctor will likely start you on a low dose of Wegovy and increase the dose slowly every 4 weeks until you reach a maintenance dose. 

You can inject Wegovy in your upper arm, stomach, or thigh areas. Rotate (change) the injection site every week. You may inject Wegovy (semaglutide) and insulin in the same general area of your body, but not immediately next to each other. 

Wegovy can help you lose excess weight when used with a reduced-calorie diet and increased physical activity, but it is not a cure for either obesity or being overweight. Continue taking Wegovy as long as your doctor advises. Do not stop treatment without talking to your healthcare provider.

Your doctor or pharmacist will show you how to correctly inject Wegovy. Make sure you understand these instructions. Ask your healthcare providers if you’re unclear about any part of the process. 

Wegovy pens that are stored in the refrigerator should be left to warm to room temperature before the injection. Check the injection solution in the Wegovy pen before injecting it. The solution should be clear and colorless without any visible particles. Do not inject Wegovy if the solution appears thickened, cloudy, colored, or has visible solid particles. Also, do not use Wegovy pens that are past the expiration date.

Never reuse a Wegovy pen or share it with others. This is a single-dose disposable pen and should be disposed of in a puncture-resistant container as explained by your doctor and pharmacist.

Missed dose: If you miss a dose of Wegovy, take it as soon as you remember as long as your next dose is at least 48 hours (2 days) away. If there are less than 48 hours left for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take a double dose or extra medicine to make up for a missed dose. If you miss more than two doses of Wegovy, call your doctor. You may need to go back to a lower dose.

Storage: Store Wegovy pens in the refrigerator (36°F to 46°F or 2°C to 8°C). You can also store the pens at room temperature (46°F to 86°F or 8°C to 30°C) in the original carton, as long as the cap hasn’t been opened, for up to 28 days. Do not freeze Wegovy. Do not use Wegovy pens that were frozen and thawed.

Unused medicine: Unused Wegovy should be disposed of in a way that children, other people, and pets cannot get to them. Do not throw Wegovy in the trash or flush it down the toilet. The best way to dispose of expired or unneeded Wegovy is through a drug take-back program. Learn more about proper medication disposal

Wegovy Warnings


Wegovy Risks, Warnings, and Complications


Wegovy can cause or worsen health problems in certain people. Talk to your doctor or pharmacist about other options for chronic weight management if you are at an increased risk of complications from this drug. Some of the risks of Wegovy use include:

  • RISK OF THYROID CANCER: Animal studies have shown that taking Wegovy can increase the risk of thyroid C-cell tumors. This risk has been found to be dose- and treatment-duration dependent, meaning a higher dose and longer treatment duration are associated with a greater risk. 

    It is not known if Wegovy causes thyroid C-cell tumors, including medullary thyroid carcinoma, in humans. There are case reports of medullary thyroid cancer in patients treated with liraglutide, which is also a GLP-1 receptor agonist. However, the link between thyroid cancer and GLP-1 receptor agonists has not been definitively established.

    People with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia type 2 (MEN 2) should not take Wegovy. You should seek immediate medical care if you develop a mass in your neck, difficulty swallowing, trouble breathing, or persistent hoarseness while on this medicine.

  • ACUTE PANCREATITIS: There are reports of acute pancreatitis (an inflammation of the pancreas), including both fatal and non-fatal hemorrhagic or necrotizing pancreatitis, in patients treated with semaglutide and other GLP-1 receptor agonists. 

    Call your doctor immediately if you develop severe persistent abdominal pain that may spread to the back and may be accompanied by vomiting. You will need to stop Wegovy if you have suspected or confirmed acute pancreatitis.

  • GALLBLADDER PROBLEMS: There is an increased risk of cholelithiasis (gallstones) and cholecystitis (gallbladder inflammation) while on Wegovy. This risk is higher in pediatric patients taking Wegovy. Additionally, rapid or significant weight loss also increases the risk of cholelithiasis (gallstones). Tell your doctor without delay if you develop right upper or middle stomach pain, right shoulder pain, fever, chills, nausea, vomiting, jaundice (yellowing of the eyes or skin), or light-colored stools. 

  • HYPOGLYCEMIA (LOW BLOOD SUGAR): Wegovy contains the generic drug semaglutide which is the same active ingredient as the diabetes medication Ozempic. In addition to helping you lose weight, Wegovy (semaglutide) can also cause hypoglycemia or low blood sugar.

    If you have diabetes and are taking insulin or oral diabetes medications alongside Wegovy, you may be at an increased risk of severe hypoglycemia. Talk to your doctor about what to do if you develop signs and symptoms of hypoglycemia, such as dizziness, weakness, sweating, hunger, nausea, fast heartbeat, or confusion. 

    If you have diabetes, your healthcare provider will monitor your blood glucose before starting Wegovy and during treatment. You may need to reduce the dose of your insulin or oral diabetes medications to lower the risk of hypoglycemia (low blood sugar).

  • ACUTE KIDNEY INJURY: There are reports of kidney damage and worsening kidney failure in patients treated with semaglutide. In some cases, the acute kidney injury was severe enough to require hemodialysis. Before starting Wegovy, tell your doctor if you have a history of kidney problems. Call your doctor if you develop vomiting, diarrhea, or dehydration. Your doctor will monitor kidney function when you first start Wegovy and during the dose escalation if you have underlying renal impairment or severe adverse gastrointestinal side effects that may lead to volume depletion.

  • ALLERGIC REACTIONS: There are reports of serious hypersensitivity reactions including anaphylaxis (throat closing) and angioedema (swelling) leading to difficulty breathing in patients who took Wegovy. Stop taking Wegovy and seek emergency medical care if you develop an allergic reaction to this drug. Tell your doctor if you have had allergic reactions to other GLP-1 receptor agonists in the past. 

  • DIABETIC RETINOPATHY: Clinical trials have shown that adults with type 2 diabetes and BMI 27 kg/m2 or greater can develop diabetic retinopathy (eye complications). This is because of the rapid improvement in blood glucose control on Wegovy which can temporarily worsen diabetic retinopathy. If you have a history of diabetic retinopathy, your doctor will monitor you closely during Wegovy treatment for signs of progression.

  • INCREASED HEART RATE: Adults and children taking Wegovy may have an increased resting heart rate. Your doctor will monitor your heart rate regularly. Call your doctor if you develop palpitations or a racing heartbeat while at rest during treatment with Wegovy. You may need to stop Wegovy if your heart rate remains high.

  • SUICIDAL IDEATION AND BEHAVIOR: There are reports of suicidal behavior and ideation with other drugs used for chronic weight management. Tell your doctor if you or your family members notice new or worsening depression, changes in mood, or suicidal thoughts or behavior while you are being treated with Wegovy. Avoid taking Wegovy if you have active suicidal ideation or a history of suicide attempts.


Precautions Before Starting Wegovy

Tell your doctor if you have ever had an allergic reaction to semaglutide (Wegovy, Ozempic, Rybelsus), any of the active or inactive ingredients in Wegovy, any other GLP-1 receptor agonist, or any other drugs. Your pharmacy can give you a list of ingredients. Examples of other GLP-1 receptor agonists include dulaglutide (Trulicity), liraglutide (Victoza, Saxenda), exenatide (Byetta, Bydureon), and lixisenatide (Adlyxin, in Soliqua). 

Give your doctor and pharmacist a complete list of your medications, including prescription medicines, over-the-counter medicines, dietary supplements, and herbal products. This can help avoid potentially dangerous interactions between your medications.

Give your doctor a complete medical history. Wegovy may not be safe for people with certain medical conditions, such as pancreatitis, gallbladder disease, kidney disease, diabetic retinopathy, or mental health issues. Also, tell your doctor if you have recently had diarrhea, vomiting, or dehydration.

Tell your doctor if you are pregnant, could be pregnant, or are planning a pregnancy soon. Your provider may recommend stopping Wegovy 2 months before a planned pregnancy. Also, tell your doctor if you are breastfeeding.

Talk to your doctor about what to do if you have major changes in your diet or activity levels or have an infection, injury, or unusual mental stress. These conditions can affect your blood sugar levels.

Precautions During Use of Wegovy

Keep all your medical and lab appointments while using Wegovy.

Contact your doctor if you experience any changes in mental health while on Wegovy, including changes in mood and behavior, new or worsening depression, or suicidal ideation or behavior. Members of your household should know how and when to seek help from healthcare professionals if you are unable to do so yourself.

Call your doctor if you become pregnant while on Wegovy.

Tell all your doctors you are on Wegovy, especially before any surgical procedures, including dental treatments.

Wegovy Drug Interactions

Taking Wegovy with certain other drugs can affect how the medications work. Interactions between Wegovy and other medications may increase the risk of severe adverse effects. Your health care professionals may change your dose, monitor you carefully for side effects, or switch you to a different medication if you are at a risk of drug interactions.

Give your doctor and pharmacist a complete list of your medications, including prescription drugs, over-the-counter medications, dietary supplements, and herbal remedies. Also, tell your healthcare professional if you smoke, drink alcohol, or use recreational drugs because some of these substances can cause serious health complications when used with prescription medications.

Wegovy Common Questions


Common Questions about Wegovy


Who can take Wegovy?

Wegovy is approved for use in adults with either obesity or overweight (a body mass index (BMI) of 30 kg/m2 or higher or a BMI of 27 kg/m2 or higher and at least one weight-related health condition). It is also approved for use in children 12 years of age and older who have a BMI at the 95th percentile or higher.



How much weight can you lose in a month with Wegovy?

A clinical trial sponsored by Novo Nordisk, the manufacturer of Wegovy, compared patients who received Wegovy with those who received placebo. The results showed that adults with obesity (with a starting body weight of 232 lbs and BMI of 38.5 kg/m2) who received Wegovy lost approximately 35 lbs or -15% of their body weight on average after taking Wegovy for 2 years. The weight loss of -15% of body weight in the Wegovy group was significantly more than the weight loss of -2.6% of initial body weight in the placebo group.



How fast will I lose weight on Wegovy?

The initial low doses of Wegovy during weeks 1 through 16 are for escalation purposes only and do not result in significant weight loss. You will likely start noticing rapid weight loss once you are on the maintenance dose of Wegovy (1.7 mg or 2.4 mg once a week) from the 17th week onwards.



Is Wegovy the same as Ozempic?

Wegovy and Ozempic contain the same active ingredient, semaglutide. However, Wegovy is for weight loss, and Ozempic is for diabetes, and they are dosed differently.



Can I take Ozempic for weight loss?

Ozempic is not approved for chronic weight management. However, it is sometimes used off-label for this purpose.



How long can you stay on Wegovy?

There is no fixed treatment duration for Wegovy. You will likely take this drug for at least a few months. Your dose will be slowly increased over the first 5 months. Then you can continue taking Wegovy at the maintenance dose as long as you continue losing weight and don’t have bothersome side effects.



How to inject Wegovy?

Wegovy comes in a pre-filled single-dose disposable pen for injection under the skin of your upper arm, thigh, or abdomen. Wash your hands before injecting the medicine. Clean the injection site with soap and water or an alcohol swab. Remove the pen cap when you’re ready to inject. You cannot start and then stop the injection midway and restart. Press the pen into your skin. You will hear two clicks. The first click tells you the injection has started and the second click tells you the medicine is still being injected. Continue holding the pen against your skin until the yellow bar in the pen window is not moving anymore.



What is the list price of Wegovy?

The list price of Wegovy is $367.32 per package. You may be able to obtain Wegovy at a lower price with a BuzzRx prescription discount card or manufacturer coupon.
