Bringing medication on board doesn’t have to be stressful — as long as you understand airline and customs regulations. This guide explains which medicines can go in your carry‑on, which should be checked, and what documentation you’ll need to avoid issues during security or at international borders.
I. Two Core Principles
When deciding how to pack your medication, keep these two rules in mind:
1️⃣ Is it essential during the flight?For example, insulin or emergency medication (e.g., angina tablets) must stay with you, while common cold medicine can go in checked luggage.
2️⃣ What form is it in?Solid (tablets/capsules), liquid (syrups/gels), or special items (needles, alcohol‑based products) follow different security rules.
II. Carry‑On vs. Checked: Category by Category
The table below summarizes what can be carried on, what must be checked, and what proof you may need.
III. Required Medical Documentation
To pass security smoothly, prepare both originals and photocopies of the following when applicable:
• Liquid medication (required inflight): Hospital certificate issued within 72 hours, signed and stamped, specifying passenger name, dosage, and necessity.
• Controlled or narcotic substances / insulin: Doctor’s prescription (preferably with English translation) clearly marked ‘long‑term use, personal quantity.’
• Chronic condition medication (e.g., hypertension, diabetes):If carrying more than one‑month supply, include a copy of medical records or physician’s note.
