my son had one course of it and whilst it did clear the acne up, it returned almost immediately when the course was finished. the doctor suggested a second course but my son decided against it. it has left him with seriously dry skin on hands, face and lips. this was all about 10 years ago. he's been on oxytet for a number of years since, to keep the acne under control (which it has been) but since last october he decided he didn't want to take tablets anymore and stopped. his skin so far has been fine, but i'm not convinced it will stay that way. i too have suffered from acne rosacea since my teens and have taken oxytet almost continuously for the last 10-15 years. occasionally i stop taking it but the darned acne always returns.
you're the only one who can decide smurf, some people handle having acne better than others. as you're probably aware, it can have a devastating effect on a persons life. best of luck.
