Mounjaro patient information for New Zealand

Starting Mounjaro

Mounjaro is a prescription medicine used for adult weight management alongside food and activity changes. Your clinician checks the applicable prescribing criteria, your health history and other medicines; it is not for people under 18.

Tell us about stomach conditions, diabetes treatment, pregnancy plans and upcoming procedures. Prepare with our first consultation guide, and read the New Zealand Mounjaro consumer leaflet supplied with the medicine.

Your four-dose KwikPen

The New Zealand KwikPen contains four weekly doses of the prescribed strength. Ask your pharmacist to demonstrate it and confirm compatible needles, which are supplied separately.

Our Mounjaro dosage guide explains starting at 2.5 mg, gradual changes and maintenance doses. If a weekly injection is forgotten, use the missed-dose guide and contact your prescriber about a longer interruption.

Storage and everyday care

Keep KwikPen refrigerated at 2–8°C and protect it from freezing and excessive heat. The Mounjaro storage guide explains the room-temperature allowance and gives a travel checklist.

Discuss alcohol use with your clinician, particularly if you also use medicines that can cause low blood sugar. Our Mounjaro and alcohol guide helps you prepare that conversation.

Symptoms, contraception and safety

Nausea, diarrhoea, vomiting and constipation are common possible side effects. The side effects guide explains mild-symptom steps and when urgent assessment is needed.

Mounjaro can affect the oral contraceptive pill, so review contraception advice before starting or increasing a dose. Call 111 for breathing difficulty, collapse or swelling of the face or throat; severe persistent stomach pain needs urgent medical care.

Review treatment and plan the cost

At Stela, an initial doctor consultation costs $300 and a doctor follow-up $150. Medicine costs are separate, and Mounjaro is not publicly funded.

Monthly follow-up during the first three months reviews your response and symptoms. Use our treatment budget guide and follow-up checklist to plan ongoing care, including nutrition support when you need it.
