GLP-1 medications are a class of prescription drugs that improve blood sugar control and frequently support weight management when combined with lifestyle changes. This class of drugs is commonly called glucagon-like peptide 1 (GLP-1) agonists. Weight loss outcomes vary depending on the specific GLP-1 drug used, the prescribed dosage, and your individual lifestyle factors. These medications are generally administered via a weekly injection.Some of the more common side effects include: Nausea, Vomiting, Diarrhea.Your medical provider will typically start you on a lower dose and gradually increase it (titration) to help your body adjust and minimize these effects. Taking your medication exactly as prescribed is critical. Anti-nausea medications such as ondansetron (generic Zofran) can also be prescribed to assist in mitigating nausea if needed.
Low blood sugar levels (hypoglycemia) are a more serious risk linked to the GLP-1 class of drugs, though this risk primarily increases if you are simultaneously taking other medications known to lower blood sugar, such as sulfonylureas or insulin. GLP-1s are not recommended if you have a personal or family history of medullary thyroid cancer or multiple endocrine neoplasia. Lab studies have linked these drugs with thyroid tumors in rats; however, until more long-term studies are completed, the exact risk to humans remains unknown. They are also not recommended if you have a history of pancreatitis.
