PS. They really should have gone through this with you! And as Kath says, the chemist, not just salesperson!, is a wonder at giving you info ... they will print the flyer for you and provide good info. I sometimes reckon my chemist is more on top of drugs than my GP but that's playing favourites! Guess the chemist is continually updated on new stuff. Both both should be able to help as this is not a new drug.
