oh dear , I got caught out like this , I went to the area round the Esnaf hospital in fethiye, there are several good chemists shops there, i just went from one to another till I got what I needed, they dont speak much english,
Take the packet or wrapper of the meds with you if you have it, they may have to look it up and offer the Turkish equivalent... good luck I am sure you will get what you require!!! if you have to get the turkish equivalent its a bit of a leap of faith but it worked for me!!!
