Anything to do with prescription drugs should ideally be discussed with your GP, but presuming you just want personal opinions here goes...
I was given this drug by an over-enthusiastic Dermatologist when he noticed a single spot on my face (he was supposed to be treating my son, not me!) After a few days I started to feel really 'weird' and my skin felt tight, but I still continued. I then developed giddyness and chronic flu-like symptoms, and as I couldn't look after a small child in this condition I binned them.
The difference is Tia Mae that I didn't have a problem in the first place and I was put on a very high dose. Now you are probably on this drug for a very different reason, so if you are having worrying side-effects please see your GP or Dermatologist and I emphasize that any replies are purely individual.
