What Is the Recommended Dosage and Administration Method for Mounjaro?
The recommended starting dosage of Mounjaro (tirzepatide) is 2.5 mg once weekly for the first 4 weeks. This is a starter dose for tolerance, not for full blood-sugar control. The dose is then usually increased to 5 mg once weekly, with further gradual increases (7.5 mg, 10 mg, 12.5 mg, up to a maximum of 15 mg weekly) based on medical response and tolerance. In Malaysia, all dosing must be prescribed and adjusted by a licensed doctor.

How Mounjaro Is Administered
Mounjaro is given as a:
Subcutaneous injection (just under the skin)
Injected into the abdomen, thigh, or upper arm
Taken once every 7 days, on the same day each week
Can be taken with or without food
The injection pen is pre-filled and designed for single-use weekly dosing.
Standard Mounjaro Dosage Schedule
1. Starting Dose
2.5 mg once weekly for 4 weeks
Purpose: allow the body to adapt and reduce nausea
This dose is not intended for full glucose control
2. Therapeutic Dose
Increased to 5 mg once weekly
Many patients remain at this dose if blood sugar control is adequate
3. Dose Escalation (If Needed)
If further control is required, doctors may gradually increase every 4 weeks:
7.5 mg → 10 mg → 12.5 mg → 15 mg (maximum)
Dose escalation is strictly guided by:
Blood sugar response (HbA1c)
Side effects
Weight changes
Overall tolerance
Why Mounjaro Dosage Must Be Increased Gradually
Tirzepatide strongly affects:
Appetite
Digestion speed
Insulin release
Hormonal balance
Gradual increases help:
Reduce nausea and vomiting
Minimise dehydration risk
Improve long-term adherence
Prevent sudden metabolic stress
Skipping ahead to higher doses can cause severe gastrointestinal side effects.
What Happens If You Miss a Dose?
If your missed dose is within 4 days (96 hours) → take it as soon as possible
If more than 4 days have passed → skip it and resume on your next scheduled day
Never double dose
Always consult your doctor if multiple doses are missed.
Can the Dosage Be Changed Without Seeing a Doctor?
No. In Malaysia:
Mounjaro is prescription-only
Dose changes must be medically approved
Self-adjusting dosage increases risks of:
Severe nausea
Electrolyte imbalance
Low blood sugar (with other diabetes meds)
Dehydration
Hospitalisation
This is why structured programs such as OVA Malaysia’s medically guided care are important.
Is Mounjaro Dosed the Same Way as Ozempic?
Mounjaro and Ozempic (semaglutide) are both:
Once-weekly injections
Started at low doses
Gradually increased for tolerance
However:
Ozempic dosing ranges from 0.25 mg to 2 mg weekly
Mounjaro ranges from 2.5 mg to 15 mg weekly
Mounjaro acts on two hormone pathways (GLP-1 + GIP), while Ozempic works on GLP-1 only
Doctors decide between the two based on:
Blood sugar control
Weight-related goals
Side-effect profile
Individual tolerance
Who Needs Extra Caution With Mounjaro Dosing?
Extra monitoring is required if you:
Are elderly
Have kidney disease
Are on insulin or sulfonylureas
Have a history of severe vomiting
Have gallbladder disease or pancreatitis risk
Your starting dose may remain lower for longer in these cases.

The Takeaway
Mounjaro is taken as a once-weekly injection, starting at 2.5 mg and gradually increasing to a maximum of 15 mg weekly, depending on medical response. The slow dose-escalation process is critical for safety and tolerance. Similar injectables like Ozempic also follow a gradual weekly dosing model, but the exact dose ranges differ. In Malaysia, Mounjaro dosing must always be managed by a licensed doctor.
