Hello,
The symptoms can be due to GI side effects of
Accutane. These include inflammatory
bowel disease, pancreatitis, colitis, esophagitis/esophageal ulceration, ileitis, nausea, other nonspecific gastrointestinal symptoms. I suggest you to consult your doctor and discuss these side effects with your doctor.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided.
