FDA Approved Weight Loss: What You Need to Know About Wegovy

FDA Approved Weight Loss: What You Need to Know About Wegovy

As a nutritionist with two decades of experience, I’m often asked about the latest medications and supplements claiming to be the “magic bullet” for weight loss. One such medication that’s been generating a lot of buzz is Wegovy. So, let’s cut through the noise and get to the facts:

Yes, the FDA has approved Wegovy (semaglutide) for chronic weight management in adults. This means it’s deemed safe and effective for long-term use in individuals struggling to lose weight, with obesity or those who are overweight with at least one weight-related health condition (like type 2 diabetes or high blood pressure). Wegovy is one of the newest weight loss drugs approved by the FDA, alongside other medications like Ozempic and Mounjaro.

However, it’s crucial to understand that FDA approval doesn’t make Wegovy a quick fix. It’s not a substitute for a healthy lifestyle. Wegovy works best when combined with a balanced, diet and exercise, regular exercise, and behavioral therapy. Think of it as a tool to support your weight loss journey, not a magic wand.

Here’s what you should discuss with your doctor:

  • Your individual health history: Wegovy isn’t suitable for everyone. Certain medical conditions may make it unsafe to use.

  • Realistic expectations: While Wegovy can significantly aid weight loss, it’s essential to set achievable goals and understand that individual results vary.

  • Potential side effects: Like all medications, Wegovy can cause side effects, some of which can be unpleasant. Your doctor can help you weigh the benefits against the risks.

What is the FDA criteria for Wegovy for chronic weight management?

The FDA has specific criteria for approving weight loss medications, including those for weight loss like Wegovy. Here's a breakdown of the key criteria Wegovy had to meet:

1. Safety and Efficacy:

  • Clinical Trials: Wegovy underwent rigorous clinical trials involving thousands of participants to assess its safety and effectiveness in promoting weight loss.

  • Significant Weight Loss: The trials demonstrated that Wegovy, combined with lifestyle changes, resulted in significant weight loss compared to placebo. The FDA typically requires a medication to achieve clinically meaningful weight loss, often defined as at least 5% greater weight loss than placebo.

  • Long-Term Effects: The FDA also considers the long-term effects of the medication. Wegovy trials included follow-up periods to evaluate its sustained impact on weight and overall health.

2. Benefits Outweighing Risks:

  • Side Effects: Like all medications, Wegovy has potential side effects, some of which can be significant. The FDA carefully weighs the potential benefits of the medication against its risks.

  • Target Population: Wegovy is specifically approved for adults with obesity (BMI ≥ 30 kg/m²) or those who are overweight (BMI ≥ 27 kg/m²) with at least one weight-related health condition. This targeted approach helps ensure that the benefits outweigh the risks for the intended patient population.

3. Manufacturing and Quality Control:

  • Good Manufacturing Practices: The FDA ensures that Wegovy is manufactured according to strict quality standards to guarantee its safety, purity, and effectiveness.

4. Ongoing Monitoring:

  • Post-Market Surveillance: Even after approval, the FDA continues to monitor the safety and effectiveness of Wegovy through post-market surveillance programs. This helps identify any rare or long-term side effects that may not have been apparent during clinical trials.

In summary, the FDA’s approval of Wegovy for weight loss signifies that the medication has met stringent criteria for safety, efficacy, and quality control. However, it’s essential to remember that Wegovy is not a magic bullet and should be used in conjunction with healthy lifestyle modifications. Consulting with a healthcare professional is crucial to determine if Wegovy for weight loss drugs is appropriate for you and to discuss potential risks and benefits.

GLP-1 Receptor Agonists:

  • Semaglutide (Wegovy): Semaglutide, marketed as Wegovy, is a GLP-1 receptor agonist that has been approved for weight loss. It works by mimicking a hormone that targets areas of the brain involved in regulating appetite and food intake.

  • Ozempic for Weight Loss: Ozempic, while primarily a diabetes medication, is also used off-label for weight loss. This highlights the versatility of GLP-1 receptor agonists in managing both diabetes and obesity.

  • Diabetes Medications: Diabetes medications like Ozempic and Mounjaro are also being used for weight loss. These medications not only help in controlling blood sugar levels but also contribute to significant weight reduction, making them valuable in treating both conditions.

Which weight loss drugs are FDA approved?

There are several drugs approved by the FDA for weight loss, each with its own mechanism of action, potential benefits, and side effects. Here are some of the most common ones:

GLP-1 Receptor Agonists:

  • Semaglutide (Wegovy, Ozempic): Originally developed for type 2 diabetes, semaglutide has also been approved for chronic weight management. It mimics a hormone that regulates appetite and food intake. It is important to monitor patients with kidney disease when using weight loss injections like semaglutide.

  • Liraglutide (Saxenda): Similar to semaglutide, liraglutide also acts on the GLP-1 receptor to promote weight loss.

  • Dulaglutide (Trulicity): While primarily used for type 2 diabetes, dulaglutide can contribute to weight loss as a secondary benefit.

Combination Medications:

  • Phentermine/topiramate (Qsymia): This combination drug suppresses appetite and increases feelings of fullness.

  • Bupropion/naltrexone (Contrave): This medication combines an antidepressant with an opioid antagonist to reduce appetite and cravings.

Other Medications:

  • Orlistat (Xenical, Alli): This medication blocks the absorption of dietary fat, leading to weight loss.

  • Setmelanotide (Imcivree): This drug is specifically approved for weight management in individuals with rare genetic disorders that cause severe obesity.

More Serious Risks:It’s important to note that this is not an exhaustive list, and new weight loss medications are constantly being developed and approved. When using weight loss injections, healthcare providers should be vigilant in monitoring patients with kidney disease, diabetic retinopathy, and depression or suicidal behaviors or thoughts. Additionally, Wegovy should not be used in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2) due to the potential risk of thyroid C-cell tumors.


What is the safest weight loss shot?

It's impossible to definitively declare one weight loss shot "the safest" for everyone. Safety is relative and depends on individual factors like your medical history, allergies, other medications you take, and how your body responds to the medication.

Here's a breakdown of things to consider:

1. No Medication is Risk-Free:

  • All medications, including weight loss injections, come with potential side effects. Some people experience mild side effects, while others might have more severe reactions.

2. Individualized Responses:

  • What's safe and well-tolerated by one person might cause problems for another. This is why a thorough medical evaluation is crucial before starting any weight loss medication.

3. Common Side Effects:

  • Most weight loss injections share some common potential side effects, often gastrointestinal in nature, including:

    • Nausea

    • Vomiting

    • Diarrhea

    • Constipation

  • These side effects are often temporary and lessen over time.

4. More Serious Risks:

  • While less common, some weight loss injections have been linked to more serious potential risks, such as:

    • Pancreatitis

    • Gallbladder problems

    • Kidney issues

    • Thyroid tumors (in animal studies)

5. Importance of Medical Guidance:

  • Never self-medicate. Consulting with a qualified healthcare professional is essential. They can:

    • Assess your individual risk factors.

    • Determine if a weight loss medication is appropriate for you.

    • Choose the medication and dosage most likely to be safe and effective for your needs.

    • Monitor you for side effects and adjust your treatment plan as needed.

What is the cost of Wegovy?

The cost of Wegovy (semaglutide) can vary significantly depending on several factors, including your insurance coverage, location, and the specific pharmacy you use.

Here's a general breakdown:

  • Without Insurance: The average retail price for a one-month supply of Wegovy (0.25mg, 0.5mg, 1mg, or 2.4mg doses) can range from $1,350 to $1,700 or more.

  • With Insurance: Coverage for Wegovy varies widely among insurance plans. Some plans may cover a portion of the cost, while others may not cover it at all. It's essential to contact your insurance provider to determine your specific coverage and out-of-pocket expenses.

  • Coupons and Discounts: Novo Nordisk, the manufacturer of Wegovy, offers a savings card that may reduce the cost for eligible patients. Additionally, some pharmacies may have discount programs or coupons available.

  • Consider Long-Term Costs: While Wegovy can be expensive, it's important to consider the potential long-term cost savings associated with weight loss, such as reduced healthcare expenses related to obesity-related conditions.

Tips for Managing Costs:

  • Talk to Your Doctor: Discuss your financial situation with your doctor. They may be aware of assistance programs or alternative medications that could be more affordable.

  • Contact Novo Nordisk: Reach out to Novo Nordisk directly to inquire about their savings card and eligibility requirements.

  • Shop Around: Compare prices at different pharmacies in your area to find the most competitive rates.

  • Negotiate with Your Pharmacy: Don't hesitate to ask your pharmacist if they offer any discounts or payment plans.

Is there a generic version of Wegovy available that could be more affordable?

As of right now, there is no generic version of Wegovy (semaglutide) available.

Here's why:

  • Patent Protection: Wegovy is a brand-name medication protected by a patent, which gives Novo Nordisk, the manufacturer, exclusive rights to sell it for a certain period. This patent protection prevents other companies from legally producing and selling generic versions.

  • Relatively New Drug: Wegovy was approved by the FDA for chronic weight management in 2021. It typically takes several years for generic medications to become available after the original brand-name drug loses patent exclusivity.

When might a generic Wegovy be available?

It's difficult to predict an exact date, but it's unlikely to happen for at least a few more years. Once the patent for Wegovy expires, other pharmaceutical companies can apply to the FDA to manufacture and sell generic versions of diabetes drugs.

What are the implications of not having a generic?

  • Higher Cost: Without generic competition, the price of Wegovy remains high, making it inaccessible for some individuals.

  • Limited Options: Patients seeking a more affordable alternative to Wegovy may have limited options, as other GLP-1 receptor agonists used for weight loss are also brand-name medications with their own costs.

What can you do in the meantime?

  • Talk to your doctor: Discuss your concerns about the cost of Wegovy with your doctor. They may be able to suggest alternative weight loss medications or strategies that fit your budget.

  • Explore insurance coverage: Check with your insurance provider to see if they cover Wegovy or offer any cost-assistance programs.

  • Contact Novo Nordisk: Inquire about Novo Nordisk's savings card program, which may help reduce the cost for eligible patients.


It's essential to stay informed about potential developments in the availability of generic Wegovy. As the medication is relatively new, the situation may change in the coming years.

In conclusion, embarking on a weight loss journey requires careful consideration and a personalized approach. While medications like Wegovy can be valuable tools for some, it's crucial to remember that they are not a magic bullet and work best as part of a holistic body weight and strategy that includes healthy lifestyle modifications.

Don't get caught up in searching for the "safest" or "best" among other weight loss medications, shot in a general sense. Instead, prioritize open and honest conversations with your healthcare provider. They can assess your individual health history, discuss potential risks and benefits of different options, and help you determine if a weight loss medication is appropriate for you. Together, you can create a tailored plan that aligns with your health goals and financial situation.

Ultimately, sustainable weight management is a marathon, not a sprint. It demands commitment, effort, and a multifaceted approach. While medications might offer a helping hand, lasting success excess weight often stems from a foundation of healthy habits and informed choices.
