Commonly reported side effects include nausea, diarrhea, constipation, vomiting, abdominal pain, fatigue, and injection-site reactions during titration. Many people find symptoms ease over time, but persistent or severe symptoms should always be discussed with your prescriber. See our side-effects guide for management tips members commonly share.

Roughly $1,000–$1,300/month at US list price without insurance; manufacturer savings and self-pay vial programs may lower cost for eligible patients.
