What Is Mounjaro Tirzepatide Injection?
Mounjaro is a once-weekly injectable prescription medication that mimics two natural hormones (GLP-1 and GIP) involved in blood sugar control and appetite regulation. It is approved for managing type 2 diabetes and is being increasingly used off-label for weight loss.
Mounjaro works by:
- Slowing digestion
- Reducing appetite
- Increasing insulin secretion
- Lowering blood glucose
Common Side Effects and How to Manage Them
Many users of Mounjaro tirzepatide injection experience mild to moderate side effects, particularly during the first few weeks of use. These symptoms are typically related to the gastrointestinal system.
1. Nausea
Why it happens: The drug slows down stomach emptying, which can cause discomfort or queasiness.
Tips to manage:
- Eat smaller, more frequent meals
- Avoid fatty or spicy foods
- Stay hydrated with electrolyte-rich fluids
- Ginger tea or peppermint may offer natural relief
2. Diarrhoea or Constipation
Why it happens: Mounjaro affects gut motility, sometimes increasing or decreasing it too much.
Tips to manage:
- For diarrhoea: Stick to a bland diet (bananas, rice, applesauce, toast)
- For constipation: Increase fiber intake and drink more water
- Consider over-the-counter remedies as needed (but consult your GP)
3. Loss of Appetite
This is often welcomed by those using Mounjaro for weight loss, but it’s important to maintain proper nutrition.
Remedy:
- Choose nutrient-dense meals even if smaller
- Use meal replacement shakes or supplements, especially if you’re buying weight loss products online
4. Injection Site Reactions
What to watch for: Redness, itching, or swelling.
Tips:
- Rotate injection sites
- Clean the area with alcohol before injecting

5. Fatigue or Headaches
May occur due to dehydration or blood sugar fluctuations.
Solutions:
- Monitor blood sugar levels regularly
- Increase fluid intake
- Ensure you’re eating balanced meals
