How Long Do Zepbound Side Effects Last

Linda Girgis | MD

Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 20th, 2026.

Most Zepbound side effects typically last 2-4 weeks as your body adjusts to the medication. The most common side effects include nausea, vomiting, diarrhea, and constipation, with nausea being reported in up to 29% of patients during clinical trials. These gastrointestinal symptoms usually peak within the first few weeks of starting treatment or increasing dosage, then gradually subside. Some patients may experience side effects for up to 8 weeks, particularly when transitioning to higher doses. Serious side effects like pancreatitis or severe allergic reactions require immediate medical attention and may persist longer. If side effects remain severe or don't improve after 4-6 weeks, consult your healthcare provider about adjusting your treatment plan.
