Semaglutide acts on the GLP-1 receptor, while tirzepatide acts on both GIP and GLP-1 receptors. Both have specific FDA-approved products and indications, and the appropriate option depends on diagnosis, eligibility, risks, access, and clinician guidance.

How semaglutide works

Semaglutide acts on the GLP-1 receptor

Semaglutide is the active ingredient in products with different approved uses. Wegovy is used for chronic weight-management indications, while Ozempic and Rybelsus are used for type 2 diabetes-related indications.

How tirzepatide works

Tirzepatide acts on both GIP and GLP-1 receptors

Tirzepatide is the active ingredient in Zepbound and Mounjaro. Zepbound and Mounjaro are not interchangeable labels; clinicians should explain which product fits the diagnosis and indication.

FDA-approved uses

Product distinctions matter

A medication name is not enough. Wegovy, Ozempic, Rybelsus, Zepbound, and Mounjaro have different labels, indications, forms, and warnings. Ask your clinician which product is being discussed and why.

Effectiveness

Clinical studies measure outcomes in specific populations

Weight and glycemic measures

Studies may measure weight, A1c, cardiometabolic markers, discontinuation, and adverse events in defined trial populations.

No universal winner

Trial results do not replace individualized assessment of eligibility, contraindications, tolerability, access, and clinical goals.

Safety

Side effects, contraindications, and warnings need product-specific review

Ask about thyroid C-cell tumor warnings, pancreatitis symptoms, gallbladder disease, severe gastrointestinal symptoms, kidney concerns related to dehydration, diabetic retinopathy warnings where relevant, hypoglycemia risk with insulin or insulin secretagogues, hypersensitivity, and peri-procedure considerations.

Dosing and administration

Discuss the plan without self-adjusting doses

FDA labels include product-specific administration and dose-escalation instructions. Patients should not personalize dosing from internet summaries; they should follow the prescribing clinician and product label.

Access and costs

Insurance and supply can shape real-world options

Costs vary by product, diagnosis, insurance coverage, prior authorization, pharmacy access, and whether the clinic is cash-pay. Ask what total treatment costs include.

Compounded products

Compounded products are not automatically equivalent to FDA-approved products

FDA warns that unapproved versions of semaglutide and tirzepatide do not undergo FDA review for safety, effectiveness, and quality before marketing. Ask how any medication is sourced and whether an FDA-approved product could meet your medical needs.

2

Is tirzepatide always better than semaglutide?

No. Studies measure specific outcomes in specific populations, but individual choice depends on indication, contraindications, tolerability, access, cost, and clinical judgment.

3

Are Ozempic and Wegovy the same?

They both contain semaglutide, but they have different product labels and approved uses. A clinician should explain the product being discussed.

4

Are compounded versions equivalent to FDA-approved products?
