SURMOUNT-1 trial result
average body weight lost over 72 weeks on the 15 mg dose
Adults with obesity or overweight, without diabetes (Jastreboff et al., NEJM 2022). Averages, not a promise; everyone in the trial also made lifestyle changes.
Tirzepatide acts on two gut hormones, GLP-1 and GIP, which together affect appetite, fullness and how the body handles sugar.
Zepbound starts at 2.5 mg and can step up by 2.5 mg every four weeks. Many people stay at 5 or 10 mg; 15 mg is the highest dose. Your physician may hold a step or go slower.
Darker bars are the maintenance doses (5, 10 or 15 mg). Once-weekly injection under the skin of the belly, thigh or upper arm. If you take birth control pills, ask about a backup method after starting and after each increase. Schedule from the Zepbound Prescribing Information.
The most common side effects are nausea, diarrhea, vomiting, constipation, stomach pain, indigestion and tiredness. They are usually worst in the first weeks after each dose increase.
Less common but serious risks include pancreatitis, gallbladder problems, kidney problems from dehydration, low blood sugar with some diabetes medicines, and serious allergic reactions. Call us, or 911 in an emergency, if you have severe stomach pain that won't go away.

Do not use it if you or a family member has had medullary thyroid carcinoma or if you have Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). Not for use during pregnancy.
