Prilosec made my stools brown again.im happy after having yellow diarrhea for 3 months.im just curious why.what problem did it solve?thank you much.

Yellow stools: Prilosec shuts down acid secretion in the stomach. Yellowish diarrhea can be seen in irritable bowel, colitis, or intestinal infections when the stool has a rapid transit through the intestinal tract. Liver and gall bladder problems can cause yellowish stools but in your case the associated diarrhea suggests the other causes. In your case Prilosec possibly caused loose stools.

Ulcerative colitis: You are taking Asacol (mesalamine) and most likely also have ulcerative colitis. Your question has to do with normal pigment of stool by bile. The Prilosec may not have solved this. It is important to see your doctor if your stool changes color or if you experience diarrhea. You may have a flair up.

Rare side effect: It is very uncommon, but Prilosec can change the color of the stool.

Control GI bleeding: Zantac (ranitidine hydrochloride) is a h2 (histamine-2) receptor blocker used for treating and preventing ulcers in the duodenum and stomach. It is also used for treating heartburn, erosive esophagitis, and zollinger ellison syndrome. Side effects include constipation, diarrhea, fatigue, headache, insomnia, muscle pain, nausea/vomiting, GI pain, colored stools--due to GI bleeding solved by zantac.
