Question: Prilosec: ab pain & black stools?

 JenX - Thu Dec 27, 2007 2:25 pm

I started Prilosec OTC several days ago to prep for a medical procedure that will require NSAIDs (I had a duodenal perforation in the past so the Prilosec was prescribed as a precaution). Two days ago I began having stomach pains and feeling very unwell. Thinking this was a reaction to a holiday meal, I took some Pepto-Bismal tabs but just felt worse and worse. I had stomach pain for 2 days, with burning and black stools, along with decreased bowel movements, and a severe headache. I was wondering if these are expected side effects with Prilosec? (I know the black stools could be a result of the Pepto Bismol.) I didn't feel I could keep down any food for 2 days and just sipped some Sprite.

Today I had some dry toast but still have some minor stomach pain and my stomach just generally feels dicey. I can't tell if these are just expected results with Prilosec OTC (ugh), or if I'm seeing signs of a perforation again. Any insight appreciated. Thanks!

User avatar Hi JenX,

There are a few possibilities. First, you may simply have coincidentally developed a stomach virus causing some gastritis at the same time you started the prilosec.

You may also be redeveloping some gastritis. The black stools can be from pepto-bismol; however, they can also be from bleeding that may be occurring due to the gastritis.

I would recommend you talk with your doctor about this. Prilosec can cause abdominal pain as one of its side effect but black stools would be unusual.

Best wishes.
