Answers Comparison
What is the difference between semaglutide and tirzepatide?
The short answer
Semaglutide acts on the GLP-1 receptor. Tirzepatide acts on both GIP and GLP-1 receptors. They are different prescription medications with different approved products, labeling, clinical considerations and prices. Neither is automatically the better choice; a licensed clinician must decide whether either medication is appropriate for a particular person.
The two names are often placed side by side as though the choice were a product comparison. It is first a clinical decision.
What each medication does
Semaglutide is a GLP-1A class of medication that acts on a hormone your body already makes to regulate blood sugar and appetite. It is prescribed only when a licensed clinician judges it appropriate for a specific person.It is one possible part of a plan, never the whole plan. receptor agonist. Tirzepatide activates both GIP and GLP-1 receptors. That difference in mechanism does not create a universal ranking. It means the medications are not interchangeable labels for the same thing.
FDA-approved products have product-specific indications, prescribing information, contraindications, warnings and administration instructions. A clinician has to evaluate the actual product and the person—not the popularity of the ingredient name.
What the comparison should include
A useful conversation covers:
- why medication is being considered;
- medical history, current medications and relevant contraindications;
- prior response or intolerance;
- the exact FDA-approved or Compounded preparationA medication prepared by a pharmacy for a specific patient, rather than a commercially manufactured product that has been through FDA approval.These are different regulatory categories. A compounded preparation is not an FDA-approved drug, and any provider telling you otherwise is wrong. being discussed;
- the dispensing pharmacy and administration instructions;
- the full price at the recommended dose;
- the monitoring and progress-visit plan; and
- what happens if the medication is paused or stopped.
Approved products and compounded preparations are different
A compounded preparation is not a generic version of an FDA-approved drug. Compounded drugs do not undergo FDA premarket review for safety, effectiveness or quality. The FDA advises that compounded drugs should be used only when a patient’s medical needs cannot be met by an available FDA-approved drug.
If a compounded preparation is discussed, ask who compounds it, which state licenses the pharmacy, what concentration will be dispensed, how the dose is measured and who answers medication-specific questions.
The KÉRISSE position
KÉRISSE does not promise either medication before an assessment. If a clinician determines that medication is appropriate, the recommendation, exact price range and follow-up plan are explained before payment. The assessment can also conclude that neither medication is appropriate.

Hover, tap or tab to any of these for a plain-language definition.
- GLP-1 A class of medication that acts on a hormone your body already makes to regulate blood sugar and appetite. It is prescribed only when a licensed clinician judges it appropriate for a specific person. It is one possible part of a plan, never the whole plan.
- Compounded preparation A medication prepared by a pharmacy for a specific patient, rather than a commercially manufactured product that has been through FDA approval. These are different regulatory categories. A compounded preparation is not an FDA-approved drug, and any provider telling you otherwise is wrong.
- Titration Adjusting a medication dose in steps, guided by how a person responds and tolerates it, rather than starting at a target dose. It is a clinical decision made at a progress visit, not a schedule you follow on your own.
- Clinical assessment A structured review of your history, medications, goals and eligibility by a licensed clinician, ending in a decision about whether treatment is appropriate for you. An assessment is only real if no is a possible answer.
Related questions
- Is tirzepatide simply a stronger version of semaglutide?
- No. They are different molecules that act on different combinations of receptors. Marketing either one as a universally stronger or better version skips the individual safety, indication and treatment questions a clinician has to evaluate.
- Are compounded semaglutide and tirzepatide FDA-approved drugs?
- No. Compounded preparations are not FDA-approved drugs and do not undergo FDA premarket review for safety, effectiveness or quality. A provider should identify exactly what is being prescribed and where it will be dispensed.
- Does the lower price determine which medication is appropriate?
- No. Price matters to whether a plan is sustainable, but it does not establish clinical appropriateness. The clinical decision comes first; the exact product, dose, pharmacy and total cost should then be disclosed before payment.
