Wegovy (semaglutide) and Zepbound (tirzepatide) share very similar side-effect profiles: nausea, constipation, diarrhea, vomiting, and fatigue, all most pronounced during dose escalation. Some patients report Zepbound nausea as stronger at equivalent weight-loss-effectiveness doses; others find Zepbound easier to tolerate. Both carry the same black-box warning for MTC/MEN2 risk and the same general contraindications. The only way to know how you'll respond is to start one and titrate carefully under clinical supervision.
