Month 1 (starting dose 0.25 mg)
Most patients experience some nausea and reduced appetite within days. Weight loss is minimal in the first month — 2–4 pounds is typical. The starting dose is intentionally low to build tolerance.
Months 2–3 (dose escalation)
Dose increases to 0.5 mg, then 1.0 mg. Appetite suppression deepens. Most patients lose 4–8% of starting body weight by end of month 3.
Months 4–6 (therapeutic dose)
Dose typically reaches 1.7–2.4 mg. Weight loss accelerates and plateaus alternate. 10–15% body weight loss is common by month 6.
Months 7–12
Continued loss but slower. Long-term studies show ~15% body weight loss at month 12 with semaglutide and ~20% with tirzepatide.
Maintenance
Stopping medication without lifestyle changes typically results in regain. Some patients reduce dose for long-term maintenance under physician supervision.
