mounjaro_edited.jpg

Mounjaro contains tirzepatide, a dual-acting medication that mimics two natural hormones — GLP-1 and GIP. Together, they reduce appetite, slow stomach emptying, improve blood sugar control, and support clinically significant weight loss.

It is supplied as a once-weekly injection in a pre-filled pen for subcutaneous use.

Product Description

  • Inject once weekly, on the same day each week.

  • Can be injected in the abdomen, thigh, or upper arm.

  • Rotate injection sites to avoid irritation.

  • Your prescriber will provide a structured dose titration schedule to minimise side effects.

How to Use

Very common: nausea, diarrhoea, decreased appetite, constipation, vomiting.
Common: indigestion, abdominal pain, fatigue, injection site reactions, burping, hair loss.
Serious (seek urgent help): pancreatitis (severe abdominal pain), gallbladder problems (pain, fever, yellowing skin/eyes), allergic reactions, dehydration from vomiting/diarrhoea.

Possible Side Effects

  • Store in a refrigerator (2°C–8°C).

  • Can be stored at room temperature (below 30°C) for up to 21 days if needed.

  • Do not freeze. Keep in original packaging until ready to use.

Storage Information

  • Q: Can I take Mounjaro if I am trying for a baby?
    A: No. It should not be used if pregnant, planning pregnancy, or breastfeeding.

  • Q: Is Mounjaro different from Wegovy?
    A: Yes, Mounjaro activates both GLP-1 and GIP receptors, which may offer additional benefits for weight and metabolic control compared to GLP-1 only medicines.

  • Q: Can I use it with other weight loss medications?
    A: No. It should not be combined with other weight loss medicines unless prescribed by your doctor.

  • Q: How long will I need treatment?
    A: Treatment length depends on individual progress, tolerance, and prescriber review. Long-term use may be recommended to maintain results.
