Uses

What Is Wegovy?

Wegovy is a prescription medication designed for chronic weight management in adults and adolescents aged 12 and older. It is used to help individuals with obesity or those who are overweight and have weight-related medical conditions. Wegovy works by regulating appetite and reducing calorie intake, which leads to weight loss. It is administered as a once-weekly injection and is part of the GLP-1 receptor agonist class of drugs, which mimic a natural hormone in the body to help control hunger and food intake.

Who Makes Wegovy?

Wegovy is manufactured by Novo Nordisk, a Danish pharmaceutical company known for its extensive work in diabetes care and hormone replacement therapies. Novo Nordisk has leveraged its expertise in GLP-1 receptor agonists to develop Wegovy, which has gained approval for its effectiveness in weight management and reducing the risk of cardiovascular events in individuals with obesity or overweight conditions.

How Does Wegovy Work?

Wegovy works by mimicking the action of the GLP-1 hormone, which is naturally produced in the gut. This hormone plays a crucial role in regulating appetite and food intake. By activating GLP-1 receptors in the brain, Wegovy helps to reduce hunger and increase feelings of fullness, leading to lower calorie consumption. Additionally, it slows gastric emptying, which prolongs the sensation of fullness after eating. These combined effects contribute to significant weight loss and improved weight management over time.

Warnings

Avoid using this medication if you have multiple endocrine neoplasia type 2 (MEN 2) or a personal or family history of medullary thyroid cancer (MTC).

If you notice symptoms such as swelling or a lump in your neck, difficulty swallowing, a hoarse voice, or shortness of breath, contact your doctor immediately. Research involving rodents has shown that Wegovy and similar medications can lead to thyroid tumors, including thyroid cancer. However, it is unclear whether Wegovy will cause thyroid tumors or a specific type of thyroid cancer known as medullary thyroid carcinoma (MTC) in humans.

Before Taking

Allergies and Contraindications

Do not use Wegovy if you are allergic to it or if you have:

  • Multiple endocrine neoplasia type 2 (MEN 2), which involves tumors in your glands

  • A personal or family history of medullary thyroid carcinoma (MTC), a type of thyroid cancer

  • Diabetic ketoacidosis (seek immediate medical treatment)

Medical History

Inform your doctor if you have ever experienced:

  • Stomach or intestinal disorders

  • Pancreatitis

  • Kidney disease

  • Eye problems related to diabetes, such as diabetic retinopathy

  • Depression, suicidal thoughts, or other mental health issues

Animal Studies

In animal studies, semaglutide, the active ingredient in Wegovy, has been linked to thyroid tumors and thyroid cancer. It is not yet known if these effects occur in humans. Discuss your risk with your doctor.

Pregnancy

If you plan to become pregnant, stop using Wegovy at least two months beforehand, as it may harm your baby. Consult your doctor for safer alternatives during this period. Proper diabetes management and appropriate weight gain are crucial during pregnancy. Losing weight while pregnant can be harmful to the unborn baby.

There is a pregnancy exposure registry for women using Wegovy during pregnancy to collect health information about you and your baby. Talk to your doctor about participating in this registry.

Breastfeeding

If you are breastfeeding or planning to breastfeed, inform your healthcare provider. It is unknown if Wegovy passes into breast milk. Discuss the best feeding options for your baby with your healthcare provider while using this medication.

Dosages

Wegovy dosages are designed to start low and gradually increase to help minimize gastrointestinal side effects. Below is the recommended dosage schedule for patients aged 12 years and older:

Initial Dose Escalation

  • Weeks 1 to 4: Begin with 0.25 mg injected subcutaneously once a week.

  • Weeks 5 to 8: Increase to 0.5 mg injected subcutaneously once a week.

  • Weeks 9 to 12: Further increase to 1 mg injected subcutaneously once a week.

  • Weeks 13 to 16: Raise the dose to 1.7 mg injected subcutaneously once a week.

Maintenance Dose

  • Week 17 and onward: The standard maintenance dose is 2.4 mg injected subcutaneously once a week.

Adjustments for Adults

If the 2.4 mg maintenance dose is not well-tolerated, it can be temporarily reduced to 1.7 mg once a week for up to four weeks. After this period, the dose should be increased back to 2.4 mg once a week. If the patient cannot tolerate the 2.4 mg dose, discontinuation of the medication may be necessary.

Pediatric Patients (12 Years and Older)

For pediatric patients, the recommended maintenance dose is also 2.4 mg injected subcutaneously once a week. If this dose is not tolerated, it can be reduced to 1.7 mg once a week. If the patient cannot tolerate the 1.7 mg dose, discontinuation of Wegovy may be required.

How to Take Wegovy

Instructions for Use

Follow the instructions provided with your prescription and use Wegovy exactly as directed by your healthcare provider. Ensure you receive proper training on how to use this medication before starting.

Injection Method

Wegovy is administered via a pen device, injected subcutaneously into the abdomen, thigh, or upper arm. Avoid injecting into muscles or veins.

Dosage Schedule

Use Wegovy once weekly, on the same day each week, at any time of day. It can be taken with or without food.

Preparing the Injection

Prepare the injection only when ready to use. Contact your pharmacist if the medication appears cloudy, discolored, or contains particles.

Changing Injection Days

If you need to change your weekly injection day, ensure at least two days have passed since your last dose before starting the new schedule.

Rotating Injection Sites

Rotate the injection site with each dose. You can use the same body area but choose a different spot each time. Avoid areas that are tender, bruised, red, or hard, and steer clear of scars or stretch marks.

Using the Pen

The Wegovy pen is single-use, with a pre-set dose. The needle is covered and not visible. Remove the pen cap only when ready to inject. Avoid touching or pressing the needle cover to prevent injury.

Administering the Injection

Press the pen firmly against the skin and hold until the yellow bar stops moving. If the yellow bar does not move, press the pen more firmly. You will hear two clicks: the first indicates the injection has started, and the second means it is ongoing. Do not remove the pen until the yellow bar stops moving to ensure you receive the full dose.

Post-Injection

If the yellow bar does not move or stops during the injection, contact your healthcare provider. The needle cover will lock once the pen is removed from the skin, preventing reuse. Dispose of the used pen in an FDA-cleared sharps container immediately. Do not dispose of it in household trash.

Special Considerations

Individuals who are blind or have vision problems should seek assistance from someone trained to use the pen.

What If I Miss a Dose?

If you miss a dose of Wegovy, take it as soon as you remember. However, if it is close to the time for your next scheduled dose, skip the missed one.

Avoid taking extra doses to compensate for the missed one, as this can lead to an overdose. Always maintain the prescribed dosing schedule for optimal effectiveness.

How Long Does It Take Wegovy to Work?

Wegovy typically begins to show its effects within a few weeks of starting treatment. Most users notice a decrease in appetite within the first few days, and significant weight loss can be observed by the four-week mark. On average, individuals may lose around 2% of their body weight in the first month. As the dosage is gradually increased to the maintenance level, more substantial weight loss is expected over the following months, with many users achieving around 15% weight loss after 17 months of consistent use. Results can vary based on individual factors and adherence to a healthy lifestyle.

FAQ

Frequently Asked Questions

Wegovy is a prescription medication used for chronic weight management in adults and adolescents with obesity or overweight conditions. It contains semaglutide, a GLP-1 receptor agonist that mimics a natural hormone to regulate appetite and calorie intake. By reducing hunger and increasing feelings of fullness, Wegovy helps individuals lose weight and maintain weight loss when combined with a reduced-calorie diet and increased physical activity.

Wegovy typically starts at a dose of 0.25 mg once a week for the first month, gradually increasing to the maintenance dose of 2.4 mg per week over several months. This gradual escalation helps minimize side effects like nausea. While some individuals may notice appetite suppression and initial weight loss within the first few weeks, significant weight loss usually becomes more apparent after reaching the higher doses.

On average, you may see a weight reduction of about 5% within the first three months of treatment. In a cohort study of 175 patients with overweight or obesity, the total body weight loss percentages achieved were 5.9% at 3 months and 10.9% at 6 months. Other studies have shown that individuals taking Wegovy can lose an average of 15% of their body weight over a period of 68 weeks. The amount of weight loss varies, with some people losing more and others less, depending on factors like adherence to the medication, diet, and exercise regimen.

There are several reasons why you might not be losing weight on Wegovy, including not following a reduced-calorie diet, insufficient physical activity, or not taking the medication as prescribed. Additionally, individual metabolic differences and underlying health conditions can affect weight loss outcomes. If you are not seeing the expected results, it is important to consult with your healthcare provider to adjust your treatment plan.

Nausea is a common side effect when starting Wegovy, typically occurring during the initial dose escalation phase. For most people, nausea tends to subside within a few days to a few weeks as the body adjusts to the medication. To manage nausea, it is recommended to eat smaller, more frequent meals and avoid high-fat foods. If nausea persists, consult your healthcare provider for further guidance.
