You may take over the counter medications with you subject to the usual restrictions. If you need to pack prescribed medication, check with your Doctor as some airlines and some medications may require a medical letter. It is wise to take a copy of your prescription with the matching medication that you can show if necessary. Always carry your medication in your hand luggage when permitted in case you are separated from your luggage. Ensure it is in the original, correctly labelled, pharmacist packaging. Liquid medications over 100ml may need to be packed into your main luggage.
