I have been on accutane (Zenatane) for two weeks now on 40mg. I'm confused because I only take one pill a day but I've seen so many people say that they take it twice a day and that its actually better for absorption that way. Also, my side effects haven't staryed yet- my lips are slightly more dry than usual but other than that nothing. I don't even think I've had an IB yet. I know accutane effects everyone different but when should I expect to see more side effects?
