GLP-1 medication
Semaglutide
Semaglutide is a GLP-1 medication typically administered by weekly injection as part of a broader, physician-guided plan.
What it is
Semaglutide belongs to a class of medications called GLP-1 receptor agonists, which act on the same receptors as a hormone your body produces naturally.
It was first studied for type 2 diabetes and has since also been studied for chronic weight management.
How treatment works
Semaglutide is generally started at a low dose, which a licensed provider may increase gradually over weeks or months based on how someone responds.
It's typically used alongside changes to nutrition and physical activity, not as a standalone approach.
Who might discuss semaglutide with a healthcare provider
- People interested in physician-guided weight management who want to understand whether a GLP-1 medication could be appropriate for their situation.
- People who have discussed weight-related health measures with a provider and want to explore medical options alongside lifestyle changes.
Eligibility isn't based on BMI alone. A licensed healthcare professional reviews your full health history before recommending any treatment.
What the process looks like
- 1Complete an online health intake so a licensed provider has the information they need to evaluate your situation.
- 2A licensed healthcare professional reviews your intake and determines whether semaglutide (or another option) may be appropriate.
- 3If prescribed, a pharmacy dispenses the medication and next steps — including dosing and follow-up — are explained clearly.
- 4Ongoing check-ins support any dose adjustments and let you raise questions as treatment continues.
Frequently asked questions
Does starting an intake mean I'll be prescribed semaglutide?
No. Completing an intake starts a clinical evaluation — it doesn't guarantee a prescription. A licensed healthcare professional determines whether semaglutide, a different option, or no medication at all is appropriate for you.
How is semaglutide taken?
For weight management, semaglutide is typically administered by subcutaneous injection on a weekly schedule. Your provider will confirm the specific plan for you.
Is semaglutide the same as tirzepatide?
No — they're related but distinct medications. See our comparison of semaglutide and tirzepatide for a closer look at the differences.
