I’ve been on pantoprazole for about a week. The doctors think I have a GI bleed last week which was causing black stools since I have taken the meds I have normal colored stools now and some side effects of burning has gone away. They think I might have an ulcer but won’t be able to tell till I do my endoscopy. I’m still on pantoprazole this is the 5th day. It is my college grad party tonight is it okay if I drink? Please help
