Below is a summary of the most important GLP-1 drugs, including Ozempic, Wegovy and others, with emphasis on their indications, results, dosing, adverse effects, and costs.

1. Ozempic (Semaglutide)

Primary Use: Managing Type 2 diabetes.

Secondary Use: Off label weight loss.

FDA Approval: Approval for the treatment of diabetes, although it is commonly recommended for weight loss which does not fall with the approval.

Dosage: Once a week injection.

Effectiveness: Allowing off label induction, average weight loss accounts for 10-12%, and its blood sugar level control is topnotch.

Side Effects: Risk of low blood sugar when used along with other medications, nausea, vomiting, constipation, diarrhea etc are some of the side effects of this medication.

Cost: For diabetes treatment this medication can be covered with insurance but when prescribed for weight loss, it can be costly and not many insurers cover it.

2. Wegovy (Semaglutide)

Primary Use: General weight management (26 BMI) or with qualifications (30 BMI) individuals.

FDA Approval: It has been prescribed and approved for weight loss specifically.

Dosage: Weekly dose that comes in higher concentration than Ozempic but once a week only.

Effectiveness: At least 10-15% of the bodyweight is what most patients lose, and there are notable patients who lose more than that.

Side Effects: Patients who take Ozempic and Wegovy will have similar side effects where the most reported one is nausea.

Cost: Relatively expensive, especially when purchasing it for weight loss purposes as there is not always insurance to cover the cost.

3. Saxenda (Liraglutide)

Primary Use: Weight management.

Secondary Use: Management of Type 2 diabetes (as Victoza).

FDA Approval: Approved for treatment of diabetes (as Victoza) as well as overweight.

Dosage: Injection is required everyday and there is more dosage for weight loss purposes than for diabetes.

Effectiveness: Most individuals notice loss in an average of 8 – 10 percent body weight.

Side Effects: Difficulty concentrating, fatigue, nausea and vomiting, diarrhea stand as the main side effects; however, all of them are tolerable after increment of dose.

Cost: Costly, in addition, the insurance cover also differs for the weight loss determination.

4. Trulicity (Dulaglutide)

Primary Use: Management of Type 2 diabetes.

Secondary Use: N/A, although some unintended instances exist but not approved for weight loss by FDA.

FDA Approval: For managing diabetes, only weight loss is not approved.

Dosage: Injection is given weekly.

Effectiveness: Helps in controlling blood sugar, even though weight loss is not significant and is lesser than what is achieved through ozempic or wegovy.

Side Effects: Same as other GLP-1 drugs such as nausea and diarrhea.

Cost: Effective management of diabetes and seen to be less expensive than Wegovy and Saxenda.

5. Bydureon (Exenatide)

Primary Use: Managing Type 2 diabetes.

Secondary Use: Used to a lesser extent for weight loss.

FDA Approval: Approved for control of diabetes even without the ability of losing weight.

Dosage: Once in a week such as with Exenatide injections. (extended release).

Effectiveness: Great for diabetes management but they do little to help with weight loss.

Side Effects: Similar to those manifested by other GLP-1 drugs of the kind but injection reactions may happen due to the style of extended release formulation.

Cost: In most circumstances, these costs are lower than compared to newer GLP 1 drugs as they are often reimbursed for diabetes.

Summary of Effectiveness and Considerations

Medication Primary FDA-Approved Use Secondary Use Weight Loss Potential Administration Typical Side Effects Ozempic Diabetes Off label for weight loss 10-12% Weekly injection Nausea vomiting Wegovy Weight Loss N/A 10-15% Weekly injection Nausea vomiting Saxenda Weight loss Diabetes (as Victoza) 8-10% Daily injection Nausea vomiting Trulicity Diabetes Off label weight loss Moderate Weekly injection Nausea diarrhea Bydureon Diabetes Limited weight loss use Minimal Weekly injection GI issues, injection site reactions

Cost Comparison

Ozempic and Wegovy: High, often not covered for off label weight loss use. Saxenda: High cost, very little insurance coverage for weight loss. Trulicity and Bydureon: Tend to be cheaper owing to long market exposure, more favourable insurance coverage for diabetes. Choosing the Right GLP 1

Those with diabetes seeking additional weight loss may benefit from Ozempic or Trulicity. For those who are strictly focusing on weight management, Wegovy or Saxenda are more effective and reaching a higher percentage of weight loss with Wegovy as there is more promise with the drug.
