Travellers on Mounjaro or Wegovy warned about travel insurance risk

Ed Milner | Last update: 20th June 2025

TL;DR:

• If you are travelling while on Mounjaro or Wegovy (or other weight loss drugs), declare your weight loss drugs and medical history when booking travel insurance
• Not disclosing Mounjaro or Wegovy could invalidate your cover
• Carry a doctor’s letter or prescription and check entry rules for your destination
• Store your medication correctly (fridge bags, carry-on only, no checked luggage)
• If your jab is for off-label use or not prescribed, that’s a red flag for insurers

Why your jab could void your insurance — even if it’s working

You’ve done all the hard work — stuck to your plan, lost weight, booked a holiday. But if you don’t declare your weight loss treatment when buying travel insurance, you could be left with no cover if something goes wrong abroad.

Insurers consider GLP-1 weight loss drugs like Mounjaro or Wegovy as prescription-only medications — and part of your medical history. If you fall ill or need medical help and haven’t disclosed your medication or condition? You may be refused a payout.

That includes:

• Needing medical care linked to the medication
• Cancelling due to a side effect
• Having a pre-existing condition (like type 2 diabetes or obesity) linked to the jab

Three things every SlimrChat traveller must do while on Mounjaro, Wegovy or other weight loss drugs

1. Declare everything when booking insurance

Yes, even if your weight loss jab is working perfectly. Yes, even if you feel fine. Insurers expect you to declare:

• Pre-existing conditions
• All prescription medications
• Any hospital visits or new diagnoses
• Off-label or private use of a drug

If your jab isn’t prescribed (e.g. you’ve bought it privately and off-label), some insurers may refuse cover completely. Others may charge more or apply exclusions. Always check.

2. Travel with proof of prescription and proper storage

You should always carry a copy of your prescription or a doctor’s letter, especially if you’re bringing injectable medication. Some countries — including parts of the Middle East and Asia — have strict rules about travelling with syringes or hormones.

• Keep your medication in its original packaging
• Bring a cool bag or medical travel case (your jab needs to stay chilled between 2°C–8°C)
• Store it in hand luggage — never in hold baggage
• Declare it at security if asked

3. Check the entry rules of your destination

Some countries ban or tightly regulate GLP-1 drugs — even with a prescription. You may need to apply for permission to bring them in, or have your paperwork checked at the border.

👉 Always check with the embassy or official government website before you fly
👉 If in doubt, ask your doctor or pharmacist to help you prepare the correct documents
