Heathrow Scraps 100ml Rule – But What Does it Really Mean for Travellers with Medication?
With Heathrow scrapping the 100ml liquid rule, many travellers will be breathing a sigh of relief, particularly those who rely on liquid medication. But experts warn the change could give a false sense of security, especially once people leave the UK.

Hannah Mayfield, a money expert working with PayingTooMuch, speaks to YCB on Heathrow airport scrapping the 100-ml liquid rule: “Heathrow’s decision to scrap the 100ml liquid rule is welcome news for travellers. However, anyone travelling with pre-existing medical conditions should still take extra care with their medication, as the risks extend well beyond airport security.
Even if you’re no longer required to show the details of your prescription at Heathrow’s security point, it’s still important to carry one with you. If your medication is lost, stolen, or damaged while abroad, replacing it can be costly and time-consuming- and without the prescription, you may also struggle to make a travel insurance claim.
Always pack essential medication in your hand luggage and keep a copy of your prescription with you. Without it, you could face problems if your medication contains controlled substances, including delays at overseas airports or difficulties obtaining a replacement. It’s worth checking regulations with your airline and the countries you’re visiting well before you travel.
While some airports no longer require all items to be removed from hand luggage during security checks, rules can still vary around the world. Take time to familiarise yourself with the procedures at the airports you’re visiting to avoid any surprises.
Finally, having the right travel insurance can help cover the cost of prescriptions if something goes wrong. When looking for affordable cover comparing policies will ensure you get the protection you need so you can travel with confidence and peace of mind.” Says Hannah Mayfield.
We also spoke with Dr Asimah Hanif, a GP, working with travel insurance provider Staysure, and she says:
“For travellers who rely on liquid medication, the removal of the 100ml restriction at Heathrow is a reassuring change, as it reduces the likelihood of essential medicines being questioned or confiscated at security.
However, it’s important to remember that this rule may not apply at other airports – particularly on return flights – where liquid limits could still be enforced. This can catch people out, especially if they’ve already used some of their supply while away.
From a medical perspective, losing access to prescribed medication abroad can be serious, which is why having appropriate medical travel insurance in place is an important part of travelling safely with a health condition. I’d still advise patients to carry medicines in their original packaging, keep a copy of their prescription, and plan ahead in case different security rules apply on the way home.”
