Starting Mounjaro is a big step towards better health and weight control, but like all prescription treatments, it can cause some side effects — most of which are mild and temporary. Understanding what to expect helps you stay confident and make the most of your journey.
How Mounjaro Works in the Body
Mounjaro (tirzepatide) mimics two natural gut hormones — GLP-1 and GIP — which regulate blood sugar and appetite. As your body adjusts, these hormonal changes may cause digestive symptoms during the first few weeks.
Common Mounjaro Side Effects
- Mild nausea or stomach upset
- Constipation or diarrhoea
- Fatigue or mild dizziness
- Reduced appetite
- Burping or bloating
These symptoms usually appear early on and fade as your body adapts to the medication.
How to Manage Mounjaro Side Effects
- Eat smaller, slower meals and stop when you feel full.
- Avoid greasy or spicy foods for the first few weeks.
- Stay hydrated and increase fibre intake.
- If you feel nauseous, eat bland foods such as rice or crackers.
- Maintain your weekly injection schedule for consistent results.
When to Contact a Pharmacist
If you experience vomiting that prevents fluid intake, persistent pain, or any unusual reaction, contact your PPRX pharmacist immediately.
