GLP-1 medications are prescription medicines that act like a natural hormone called glucagon-like peptide-1. Your gut releases this hormone after you eat. It helps the body release insulin when blood sugar rises, slows how fast the stomach empties, and signals fullness to the brain.
Which GLP-1 medicines are FDA-approved?
Several are approved in the United States. The ones our doctors can discuss with you include:
- Semaglutide: Ozempic® for type 2 diabetes, Wegovy® for chronic weight management and cardiovascular risk reduction in eligible adults.
- Liraglutide: Victoza® for type 2 diabetes, Saxenda® for chronic weight management.
- Dulaglutide: Trulicity® for type 2 diabetes.
- Tirzepatide (Mounjaro®, Zepbound®) works on GLP-1 and a second hormone, GIP.
How are they taken?
Most are injections under the skin, either once a week or once a day depending on the medicine. Your doctor explains how to use the one prescribed for you. EKO Labs does not publish dosing instructions.
Who should not take them?
GLP-1 medicines carry a boxed warning about thyroid C-cell tumors. They should not be used by people with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia type 2 (MEN 2). Tell your doctor about any history of pancreatitis, gallbladder disease, kidney problems or diabetic eye disease.
Common side effects
The most common side effects are stomach-related: nausea, vomiting, diarrhea and constipation. They are often worse when starting or increasing a dose. Call your doctor if they are severe or do not improve.
