Dermatologist has suggested the daily use of this oral (reinoid) drug which is used primarily to treat psoriasis. He feels it might help reduce the growth of skin cancer cells, has anyone else used Neotigasan (trade name) for this purpose? Research on line has come up with a horrible list of side effects. At this stage after reading some of the horror stories I’m reluctant to start taking. Any experienced/informed opinion would be greatly appreciated.
