Weight loss can be a challenging journey, and finding effective and safe medications to support your goals is crucial. Semaglutide, a medication initially used to treat diabetes, has emerged as a promising option for weight management. Approved by the U.S. Food and Drug Administration (FDA), semaglutide has gained attention for its potential to help individuals with obesity or overweight achieve sustainable weight loss. In this comprehensive guide, we will explore the duration of semaglutide usage, its effectiveness, potential side effects, and who can benefit from this medication.

Understanding Semaglutide

Semaglutide belongs to a class of medications called glucagon-like peptide-1 receptor agonists (GLP-1 RAs). It mimics the GLP-1 hormone released in the gut in response to eating. One of the roles of GLP-1 is to stimulate the production of insulin, which helps lower blood sugar levels in individuals with diabetes. Semaglutide has been used for over 15 years as a treatment for type 2 diabetes1.

Semaglutide for Weight Loss

While initially developed as a diabetes medication, semaglutide has shown significant potential for weight loss when used in conjunction with diet and exercise. The FDA has approved semaglutide, under the brand name Wegovy, specifically for weight management1. The typical dosage for weight loss is 2.4 milligrams, administered weekly as subcutaneous self-injections1.

Effectiveness of Semaglutide for Weight Loss

Clinical studies have demonstrated the effectiveness of semaglutide injections for weight loss. In one study involving 2,000 obese adults, participants who used semaglutide in combination with a diet and exercise program experienced remarkable results. After 68 weeks, half of the participants using semaglutide lost 15% of their body weight, and nearly a third achieved a weight loss of 20%. In comparison, participants who only made lifestyle changes without semaglutide lost about 2.4% of their weight1.

Long-Term Use and Weight Maintenance

Semaglutide is intended for chronic, long-term use, especially for individuals who have achieved significant weight loss with the medication. Like many other weight loss medications, there is a natural tendency to regain weight after losing it. A study conducted with patients taking Wegovy, which contains the same active ingredient (semaglutide) as Ozempic, found that when the medication was stopped, patients regained the weight they had lost2. Therefore, ongoing use of semaglutide is recommended for weight maintenance.

How Long Can Semaglutide Be Used?

The duration of semaglutide usage varies depending on individual factors and the recommendation of a healthcare provider. Generally, a person can stay on semaglutide as long as they tolerate the medication and their treating provider deems it appropriate. There is no specific time frame for when someone should stop taking semaglutide since it is intended for long-term use2.

Considerations for Weight Loss

If you are using semaglutide for weight loss, it is important to continue long-term use for weight maintenance. Weight loss medications, including semaglutide, can help jumpstart weight loss and assist in reaching a healthier weight. However, it is crucial to remember that sustainable weight loss is a long-term journey that requires ongoing lifestyle changes and support from healthcare professionals2.

Consultation with a Medical Provider

If you are currently taking semaglutide and considering stopping the medication, it is essential to discuss your plans with your medical provider. They can assess your individual circumstances and guide you on the best course of action. It is crucial not to make any changes to your medication regimen without consulting a healthcare professional2.

Potential Side Effects of Semaglutide

As with any medication, semaglutide may cause side effects. However, these side effects are generally mild and well-tolerated, especially when compared to the potential complications associated with obesity and overweight. Common side effects of semaglutide for weight loss may include:

  • Dizziness
  • Fatigue
  • Gastrointestinal issues (diarrhea, constipation, gassiness)
  • Headache
  • Stomach issues (nausea, vomiting, pain, or distension)1

If you experience any side effects while taking semaglutide, it is important to communicate with your healthcare provider. They can provide guidance on managing side effects and determine if any adjustments to your medication are necessary.

Who Can Benefit from Semaglutide for Weight Loss?

Semaglutide is recommended for individuals who meet specific criteria outlined by the FDA. Wegovy, the brand name for semaglutide used for weight management, is indicated for:

  1. Individuals with a body mass index (BMI) of 27 kg/m² or greater and at least one weight-related condition, such as high blood pressure, type 2 diabetes, or high cholesterol.
  2. Individuals with a BMI of 30 kg/m² or greater1.

However, there are certain contraindications for semaglutide usage. Semaglutide should be avoided if you have a history of medullary thyroid cancer, gallbladder disease, pancreatitis, or multiple endocrine neoplasia syndrome type 2 (MEN2)1. It is essential to consult with your primary care physician to determine if semaglutide is a suitable option for your weight loss journey.


Semaglutide has emerged as a valuable tool in the management of obesity and overweight. While it was initially developed as a diabetes medication, semaglutide has shown significant potential for weight loss when used in conjunction with lifestyle changes. It is important to remember that obesity is a chronic and complex condition that requires lifelong treatment. Semaglutide, in combination with diet and exercise, can offer substantial weight loss and improve overall health outcomes. However, the decision to start or stop semaglutide should be made in consultation with a healthcare provider to ensure individual suitability and ongoing support on your weight loss journey.

If you are considering semaglutide for weight loss or have any questions, reach out to your primary care physician. They can provide personalized guidance based on your medical history and help you make informed decisions about your weight management plan. Call us at 205-352-9141.
