Just for clarity, most countries require BOTH a prescription and a LABEL on the packet with your name, the name of the drug, and the amount to be taken. If you have an on line prescribing system, it would be prudent to ask for a print out. And declare ALL drugs
The only differences are that some countries have an absolute ban on drugs that can be bought over the counter elsewhere - Beechams Powders are OTC in the UK but illegal in Australia. The US have an absolute ban on diamorphine, which is a controlled rug elsewher
The difference in Dubai is that if you dont declare and they find a drug they tend to be a bit more strict.
