Mounjaro (tirzepatide) is a breakthrough injectable medication for type 2 diabetes and weight loss that has helped many patients in the UK improve their health. However, like any medicine, it can cause side effects. While most are mild and temporary, learning how to manage and reduce side effects of Mounjaro will help you stick to your treatment comfortably and safely.
This guide offers practical, NHS-aligned advice for UK patients on recognising, coping with, and preventing common Mounjaro side effects, so you can get the most from your treatment.
Understanding Why Side Effects Occur
Mounjaro works by activating hormones that regulate appetite, blood sugar, and digestion. This can slow your stomach emptying and reduce hunger, which helps with weight loss and glucose control. However, these changes can also cause side effects, especially during the first weeks or after dose increases.
Common side effects include nausea, diarrhoea, constipation, and abdominal discomfort. Knowing why they happen helps us find ways to reduce them.
Start Slow: The Importance of Gradual Dose Increase
Your healthcare provider will usually start you on a low dose (2.5 mg) of Mounjaro and increase it gradually. This helps your body adjust and lowers the risk of side effects like nausea and vomiting.
If you experience side effects, do not stop the medication abruptly without consulting your doctor. Sometimes a slower dose increase or temporary pause can help.
Diet Tips to Reduce Side Effects
1. Eat Small, Frequent Meals
Instead of three large meals, try eating smaller portions 4-6 times a day. This reduces the workload on your stomach, making nausea and fullness less likely.
2. Choose Low-Fat, Bland Foods
Fatty or greasy foods slow digestion and can worsen nausea or bloating, especially with Mounjaro slowing stomach emptying.
Focus on foods like:
- Bananas
- Plain rice
- Toast or crackers
- Boiled potatoes
- Steamed vegetables
These are easier on your stomach while providing essential nutrients.
3. Avoid Spicy and Acidic Foods
Spicy foods and citrus fruits may irritate your digestive tract and increase discomfort. Opt for milder flavours during dose escalation.
4. Stay Hydrated
Drink plenty of water—at least 1.5 to 2 litres a day—and herbal teas such as peppermint or ginger, known for soothing digestion.
Avoid sugary or caffeinated drinks as they may worsen dehydration or upset stomach.
Managing Specific Side Effects
Nausea and Vomiting
- Eat slowly and avoid lying down right after eating.
- Ginger tea or ginger candies can reduce nausea.
- Acupressure wristbands (used for motion sickness) may help some people.
- Consult your healthcare provider if nausea is severe or persistent; they may suggest medications to help.
Diarrhoea
- Stay hydrated with water and electrolyte drinks.
- Eat binding foods like bananas, white rice, and applesauce.
- Avoid high-fibre foods until symptoms improve.
- Contact your doctor if diarrhoea lasts more than 48 hours or you notice blood.
Constipation
- Increase fibre intake gradually with foods like oats, beans, fruits, and vegetables.
- Drink plenty of fluids to help fibre work effectively.
- Gentle exercise, like walking, stimulates bowel movements.
- If constipation persists, speak to your pharmacist about safe laxatives.
Lifestyle Tips to Minimise Side Effects
1. Take Your Time Eating
Chew food thoroughly and eat in a calm environment without distractions. This helps digestion and allows your body to signal fullness early, preventing overeating.
2. Avoid Alcohol
Alcohol can increase side effects like low blood sugar, nausea, and dehydration. It’s best to limit or avoid alcohol while on Mounjaro.
3. Monitor Blood Sugar Levels
If you are on insulin or other diabetes medications, Mounjaro can increase the risk of low blood sugar (hypoglycaemia). Regular monitoring helps you catch symptoms early.
When to Contact Your Healthcare Provider
Seek medical advice if you experience:
- Severe or persistent nausea and vomiting
- Signs of dehydration (dizziness, dark urine, rapid heartbeat)
- Severe abdominal pain (possible pancreatitis)
- Symptoms of allergic reactions (swelling, rash, difficulty breathing)
- New or worsening symptoms like neck lumps or jaundice
Your healthcare team may adjust your treatment or suggest supportive therapies.
