Tirzepatide (Mounjaro) Dose Chart: 2.5 mg to 15 mg, Explained
Mounjaro's dose ladder has six rungs, and where you stop matters for both results and cost. Here is the standard titration schedule, what each dose delivers, and how doctors decide when you have climbed high enough.

Clinical Editorial
Tirzepatide dosing is a ladder with six rungs: 2.5, 5, 7.5, 10, 12.5 and 15 mg, all taken once a week. Unlike semaglutide, where most patients aim for a single target dose, tirzepatide maintenance is genuinely individual. In the SURMOUNT trials, meaningful groups of patients got full results at 5 mg and never went higher. Since each rung up costs more per month, finding your lowest effective dose is both a medical and a financial decision.
The standard schedule
- 1Weeks 1 to 4: 2.5 mg weekly. Adjustment dose. Not intended to drive weight loss; it teaches your gut what is coming.
- 2Weeks 5 to 8: 5 mg weekly. First therapeutic dose. Average 15% body-weight loss at this dose in SURMOUNT-1 over the full trial. A legitimate long-term maintenance dose.
- 3If needed, in 4-week minimum steps: 7.5 mg, then 10 mg. The middle rungs, used when loss plateaus at 5 mg with good tolerance.
- 4If still needed: 12.5 mg, then 15 mg. Maximum doses, averaging 20.9% loss in trials, with the highest side-effect and cost burden.
5 mg is a destination, not a waypoint
The biggest misconception about Mounjaro is that everyone must reach 15 mg. Fifteen percent average weight loss at 5 mg is a bariatric-surgery-class result. Climb only if your progress stalls and your doctor agrees.
How doctors decide when to step up
- Weight loss has slowed below roughly 0.5 kg a week for 3 to 4 consecutive weeks at the current dose.
- Appetite suppression has clearly faded (food noise returning, portions creeping up).
- Side effects from the last increase have fully resolved.
- You can afford the next rung for at least 3 months. Stepping up for one month and back down for cost reasons whipsaws your body for nothing.
The cost dimension
Every rung costs more per unit, and you take four units a month. Before starting Mounjaro at all, price out a realistic scenario: 2 months at 2.5 and 5 mg combined, then 6+ months at whatever maintenance dose you plausibly land on. If that total makes you flinch, a closely-supervised generic semaglutide program with real follow-up care (from around ₹3,499 a month) is the honest plan-B in the same medicine class, and switching between molecules under a doctor is routine.

Frequently asked questions
What is the maximum dose of Mounjaro?
15 mg once weekly. It is reached only after stepping through every lower dose with a minimum of 4 weeks at each, and many patients never need it.
How long should I stay on 2.5 mg tirzepatide?
Four weeks. It is an adjustment dose, not a treatment dose, and staying longer than 4 weeks is only done for tolerability reasons on a doctor's advice.
Can 5 mg of Mounjaro be a maintenance dose?
Yes. In SURMOUNT-1, the 5 mg group averaged 15% body-weight loss. If you are losing steadily at 5 mg, there is no medical reason to escalate.
What if I cannot afford the higher Mounjaro doses?
Tell your doctor before it becomes an emergency. Options include holding at your current effective dose or switching to supervised generic semaglutide, which costs far less monthly. Abruptly stopping without a plan usually leads to regain.
