How long can you safely take tirzepatide?

Clinical trial data shows tirzepatide is safe through 72 weeks (18 months) with consistent safety profiles. Real-world experience extends beyond 2 years in many patients. Like other chronic disease treatments, most people require ongoing use for sustained weight maintenance.

What happens when you stop taking tirzepatide?

Discontinuation typically leads to weight regain. SURMOUNT-4 showed average 14% weight regain within 52 weeks after stopping. Appetite returns, metabolic rate may decrease, and previous eating patterns often resume. This mirrors what happens with other chronic treatments when discontinued.

Does tirzepatide lose effectiveness over time?

No evidence of tolerance or tachyphylaxis. Weight loss continues through 60-72 weeks before naturally plateauing (not from reduced effectiveness). Metabolic benefits (HbA1c, blood pressure, lipids) maintain or improve with continued treatment. Some patients successfully reduce to maintenance doses.

What are the long-term side effects of tirzepatide?

72-week data shows: GI side effects (nausea, diarrhea) typically diminish significantly after months 3-6. No increased risk of pancreatitis, gallstones, or other serious events with extended use. Safety profile remains consistent throughout treatment duration. Ongoing CVOT trials will provide 5+ year data.
