I am taking this medication for adult acne as all other antibiotics have not worked. I have been taking it 2 times per day for about a week. I have major burning sensations in my stomach/esophagus. I have woken up twice during the middle of the night and thrown from the spasms. The second time I vomitted, there was actually blood! And they gave me this wretched medication because they said accutane would be too hard on my system?!?
