Hormonal

Tirzepatide is associated with a higher incidence of gastrointestinal adverse events (nausea, vomiting, diarrhea) compared to placebo and basal insulin, which can lead to treatment discontinuation.

Tirzepatide often causes stomach problems like nausea, vomiting, and diarrhea, especially at higher doses (10mg and 15mg). These side effects are more common than with placebo or basal insulin and can cause some people to stop taking the medication. Starting at a lower dose and increasing slowly may help.
