Take them in your hand luggage

I would rather die of 'embarassment' than be stopped for suspicious reasons. You could land yourself in all sorts of trouble in a foreign country, with pills with no label on. I personally (having travelled all over the world) play it safe, and always take any medicines in my hand luggage with the correct label on. It is always better to be safe than sorry. I was stopped and searched all over in Germany once all because I smiled at one of the guards. They thought I had something to hide.
