Can You Take Medicines on British Airways? A Complete Guide

Travelling with medication can feel complicated, particularly when liquids, prescriptions or medical equipment are involved. The reassuring news is that British Airways allows passengers to carry essential medicines in their hand luggage, including certain liquid medicines above the standard 100ml limit, provided the correct checks and supporting information are in place.

Quick Answer: Yes. British Airways allows prescription medicines, tablets, inhalers, insulin and liquid medication in your cabin bag. Unlike ordinary toiletries, liquid medicine on British Airways isn't capped at 100ml and doesn't need to go in your clear plastic liquids bag — but it must be ready for separate inspection at security.

British Airways Medicine Rules at a Glance

• Prescription medicines, tablets and capsules are allowed in hand luggage.

• Liquid medicine has no 100ml limit and doesn't need to be bagged with your other liquids.

• Syringes are permitted for medical use but require a doctor's letter.

• CPAP machines and portable oxygen concentrators need prior approval via the British Airways online special assistance form.

• Extra medical supplies (ostomy equipment, PKU products, TPN feed, dialysis fluids) require a Medical Baggage Waiver Letter.

• Carry supporting documentation if appropriate.

• Declare essential liquid medicines at airport security

Liquid Medicines: The British Airways Rule Is Different From Standard Toiletries

This is the part many travellers get wrong. The usual 100ml airport security limit for liquids doesn't necessarily apply to essential medicines. British Airways advises that if you need liquid medication during your journey, you can carry as much as you need in your hand luggage, even if it exceeds the normal liquids limit, provided you have a supporting prescription or doctor's note where appropriate. The medication doesn't need to fit inside your transparent liquids bag, but you should keep it separate and ready for inspection at airport security. - Source: British Airways Help Centre – Travelling with medicines, medical supplies or medical equipment

Syringes and Sharps

If you're travelling with a diabetic condition or another need for syringes, British Airways permits them in the cabin — but airport security will expect a doctor's letter confirming why you're carrying sharp objects. Keep this with your medication, not packed away.

Tablets, Capsules and Everyday Medication

Painkillers, allergy tablets, prescription medication, vitamins and travel sickness tablets can stay in your hand luggage through screening, generally with no quantity limit for personal use.

CPAP Machines and Portable Oxygen Concentrators

This is a genuine British Airways-specific process, not a generic airline formality: if you need to use a CPAP machine or portable oxygen concentrator onboard, you must submit a request through the British Airways online special assistance form in advance. Their special assistance team reviews it and confirms approval before you fly — this isn't something you can sort out at the gate. Source: British Airways Help Centre — Carriage of Medical Equipment

Extra Medical Supplies Beyond Standard Baggage

If your condition means you need to carry additional medical items beyond your normal baggage allowance — ostomy equipment, PKU products, TPN feed or dialysis fluids, for example — British Airways requires a Medical Baggage Waiver Letter. Only the items listed on that letter travel free of charge, so it's worth applying well before your trip.

Should Medicines Go in Your Cabin Bag or Hold Luggage?

Always carry essential medication in your cabin bag. The British Airways baggage handling is no different from other airlines here: if hold luggage is delayed or goes missing, you don't want to be without medicine you need on arrival.

Packing Toiletries Alongside Medication

Ordinary toiletries — toothpaste, deodorant, sun cream, shampoo — still fall under the standard 100ml rule and must go in your liquids bag, separate from your medicine. See our British Airways Toiletries Guide for the full breakdown.

Rather than sourcing each item separately and checking every bottle against the 100ml rule, a pre-packed kit is already sized and compliant — pick the version that matches you:

British Airways Medicines Checklist

• Carry essential medication in your cabin bag, not hold luggage.

• Keep liquid medicine separate and accessible — no clear bag needed, but no hiding it either.

• Carry a doctor's letter if travelling with syringes or sharps.

• Submit a British Airways online special assistance form in advance for CPAP/POC devices.

• Apply for a Medical Baggage Waiver Letter if carrying additional medical supplies beyond standard allowance.

  
  

Frequently Asked Questions

Does British Airways limit liquid medicine to 100ml? 

No. British Airways explicitly exempts medically necessary liquid medicine from the standard 100ml rule, and it doesn't need to be packed in your liquids bag — though it should be presented separately at security.

Do I need permission to bring a CPAP machine on British Airways? 

Yes. CPAP machines and portable oxygen concentrators require prior approval through the British Airways online special assistance form — this needs to be arranged before you travel, not at the airport.

What is a British Airways Medical Baggage Waiver Letter? 

It is the British Airways authorisation for carrying essential medical supplies (such as ostomy equipment, PKU products, TPN feed or dialysis fluids) beyond your normal baggage allowance, free of charge.

Do I need a doctor's letter for syringes on British Airways? 

Yes, for sharps you should carry a letter confirming the medical need.

Can I take insulin on British Airways? 

Yes, insulin, pens and diabetes supplies are permitted in the cabin.

Medicine sorted — now sort everything else. CabinCleared's cabin-approved kits are packed to comply with the British Airways liquids rules without a second thought.

Final Thoughts

The British Airways medicine policy is more flexible than people expect, particularly on liquids — but the two areas that catch travellers out are the CPAP/POC approval process and the Medical Baggage Waiver Letter for extra supplies. Sort both in advance and the rest is straightforward.
