For general education only. This information does not diagnose a condition or replace medical advice. Your provider will determine which evaluation or treatment is appropriate for you.
How to read this table
This table compares categories of options. It does not rank them, declare a winner, or suggest that any option is right for you. Your provider determines suitability after reviewing your health history, current medicines, labs, and goals. Nothing here replaces that evaluation.
Both options are prescription treatments taken once a week. The differences that matter most to most women are the exact product and its labeling, how the body responds, and what monitoring looks like.
Approval, off label use, and compounding
FDA approval applies to a specific product, formulation, indication, and population. Off label use means an approved medicine is prescribed outside its approved labeling. A compounded preparation is not FDA approved and has not undergone the same premarket review for safety, effectiveness, and quality.
Semaglutide and tirzepatide each exist as several products with different approved uses. A weight management indication belongs to some products and not others. An ingredient name alone does not establish approval. Ask for the exact product name, formulation, and current labeling of the medicine offered to you, and whether that use is approved, off label, or compounded.
What a useful conversation covers
Ask what weight and health changes are realistic for your circumstances, what side effects should prompt a call, and how long a trial is reasonable before reassessing. Discuss nutrition, activity, sleep, and other medicines alongside any prescription.
Cost and access matter too. Ask what the plan includes and what happens if a supply changes or a dose is missed.
Side by side
Considerations worth bringing to your provider. This is not a ranking, and it does not mean any option is right for you.
Semaglutide injection
Product details- What it is
- A medicine that acts on the GLP-1 hormone pathway involved in appetite, fullness, and blood sugar regulation.
- How it is used
- Injected once a week on a regular day. Your provider explains the routine and what to do about a missed dose.
- Approval and labeling
- Approved uses differ by product and brand. Some semaglutide products carry a weight management indication and others are labeled for diabetes. Ask which product is offered.
- What the evidence supports
- In studies, this class supported weight change alongside nutrition and activity. Response varies, and no result is guaranteed.
- Common considerations
- Nausea, vomiting, diarrhea, or constipation are common, especially early. Discuss how you will manage them.
- Often not appropriate when
- There is a personal or family history of medullary thyroid carcinoma or MEN 2, or during pregnancy. Tell your provider about pancreatitis history and all medicines.
- Cost and access
- Pricing is shared after your evaluation. Ask what your plan includes, such as consultations, medication, labs, and follow up, and what happens if your plan changes.
Tirzepatide injection
Product details- What it is
- A medicine that acts on two pathways, GIP and GLP-1, both involved in appetite and metabolism.
- How it is used
- Injected once a week on a regular day. Your provider explains the routine and what to do about a missed dose.
- Approval and labeling
- Approved uses differ by product and brand. Some tirzepatide products carry a weight management indication and others are labeled for diabetes. Ask which product is offered.
- What the evidence supports

- Common considerations

- Often not appropriate when
- There is a personal or family history of medullary thyroid carcinoma or MEN 2, or during pregnancy. Tell your provider about pancreatitis history and all medicines.

Questions to bring
- Which exact product and formulation are you offering me?
