I take antihistamines all the time for dust, pollen and skin allergies. I also get travel sick and have trouble sleeping on holiday.
We are off to Ibiza on Monday and I plan to take 8 Phenergan tablets with me as they cover all three of these things. Can you carry these in your hand luggage (with proof of purchase)? I got them from an online doctor who approved the purchase but I've had them on prescription before.
I will have my HRT medicine (plus proof of prescription) as well.
