I am 21 years old and was prescribed this medication for "mild acne treatment." I have only been on this medication two days and already I am feel some side effects. My Dermatologist did not explain any side effects to me at all when prescribing this medication and gave me no instructions on even taking the medication. All he said was take one pill twice a day 1/2 hr - 1 hr after eating and thats all. I started feeling some symptoms this morning while at work. I got an upset stomach and started feeling extremely nauseous. I came home from work and immediately went to sleep. When I woke up, I felt even worse. I still feel nauseous and have upset stomach, but now I also have a loss of appetite, im tired, I feel weak and have no desire to do anything. I am debating still continuing this medication, since it is only for an acne treatment. I will probably continue for a few more days and if the side effects still persist, I will discontinue use. I had no idea why I all of a sudden felt this way, so decided to research a little. I am very glad I found this website, or else I would probably be wondering what the heck is going on. Thank you for all the posts about your side effects. Now I am aware of why I am feeling the way I am. Much appreciated...
