Can You Take Medicines on Wizz Air? A Complete Guide (2026)

Wizz Air runs one of the more document-driven medical policies among Europe's low-cost carriers. Rather than case-by-case judgement calls at the gate, almost everything — from using a CPAP machine in flight to bringing a portable oxygen concentrator — routes through a single named document: the "Fit to Fly" form. Knowing when you need it, and when you don't, saves a lot of last-minute stress.

Quick Answer: Yes. Wizz Air allows prescription medicines, insulin and standard medical devices in the cabin. Essential medicines need a medical certificate confirming why you need them. Certain devices — CPAP/BiPap machines if you plan to use them in flight, and portable oxygen concentrators — require Wizz Air's specific "Fit to Fly" form, issued within 6 days of your flight.

Wizz Air Medicine Rules at a Glance

✔ Keep all medicine in your hand luggage — Wizz Air is explicit that it should never go in the hold.

✔ Essential medicines (including insulin) need a medical certificate confirming necessity, shown at security if requested.

✔ CPAP, BiPap, nebulisers and ventilators can travel switched off with no paperwork — but need the Fit to Fly form if you intend to use them during the flight.

✔ Portable Oxygen Concentrators need both equipment evidence and a Fit to Fly form, and must be an approved model.

✔ Contact the Special Assistance Call Centre at least 48 hours before departure if travelling with any of these devices.

✔ Wizz Air cannot refrigerate medication on board.

Liquid Medicines: Carry Your Certificate

Unlike some carriers that publish a blanket exemption for liquid medicine over 100ml, Wizz Air's own guidance centres on documentation rather than a stated bag exemption: keep essential medicines with you and carry a medical certificate confirming you need them for your trip, ready to present at security if asked. If you're travelling with a liquid medication over 100ml, it's worth having that certificate on hand regardless, since Wizz Air doesn't spell out the same no-bag-needed allowance that other airlines do.

Insulin and Essential Medicines

Insulin can be carried free of charge, but Wizz Air asks for a medical certificate confirming you need it during your trip, and Wizz Air can't provide a refrigerator bag on board — plan your own cooling if needed.

CPAP, BiPap, Nebulisers and Ventilators: Off vs In-Use

This is the detail that catches people out. If your device — CPAP, BiPap, nebuliser or ventilator — is staying switched off for the flight, it travels in the cabin with no form required. But if you plan to actually use it in flight, you need the Fit to Fly form, issued within 6 days of departure, and you must contact the Special Assistance Call Centre at least 48 hours ahead so they can verify your documents. Check in at least 2 hours before departure and be ready to present both the device and the paperwork. Skip this process and Wizz Air can refuse to carry you. The device itself travels as an additional free item, separate from your normal cabin bag. Source: Wizz Air — Special Assistance Information

Portable Oxygen Concentrators (POC)

POCs that don't contain compressed gas or liquid oxygen are allowed, but only specific approved models — Inogen One, Respironics SimplyGo and AirSep FreeStyle are among those on Wizz Air's approved list — and you'll need both evidence of the equipment and a signed Fit to Fly form. Carry enough charged batteries to cover the flight and any delays (maximum two spares, terminals protected against short circuits). Breathing aids containing compressed gas or liquid oxygen aren't permitted at all, in cabin or hold.

Extra Onboard Oxygen

If you need supplementary oxygen during the flight, you can't bring your own cylinder — Wizz Air can supply it instead, but only after you contact the Assistance Call Centre at least 48 hours ahead with a signed Fit to Fly form confirming you don't need more than 250 minutes of continuous oxygen at 2L/min, and accepting that oxygen can't be provided during take-off or landing. This service costs an additional €55.

Should Medicines Go in Your Cabin Bag or Hold Luggage?

Always the cabin bag. Wizz Air's guidance on this is unambiguous — medicine should stay with you at all times, not in checked baggage.

Packing Toiletries Alongside Medication

Ordinary toiletries — toothpaste, deodorant, sun cream, shampoo — still fall under the standard 100ml liquids rule and need to go in your clear bag, separate from any medical items or certificates. Rather than sourcing each item separately and checking every bottle against the limit, a pre-packed kit is already sized and compliant — pick the version that matches you:
