What are GLP-1 agonists?

GLP-1 agonists in brief

The group and the named medicine

GLP-1 agonists are a group of medicines. To learn what they do, read an overview of the whole group first, then the drug page for the one named medicine you are offered, and ask your prescriber how that medicine applies to you.

What to look at

The Cleveland Clinic GLP-1 agonists page explains what they are, how they work and their side effects. The MedlinePlus semaglutide injection drug information covers one named medicine in the group.

A skeptic's question: is a source describing the whole group of medicines, or one named drug? Details such as dosing and side effects can belong to one drug only. Check that before you apply what you read to a different medicine.

Questions about your named medicine

• Note the name of any medicine you are asked to consider, not only the group name.
• Ask your prescriber why this medicine and not another option.
• Ask what side effects to watch for and what to do if they appear.
