Hello,
Black stools after pepto bismol is temporary and harmless condition.
Pepto bismol (bismuth subsalicylate) may cause black stool in some patients. After taken it combines with sulfur in the colon and forms insoluble black salt - bismuth sulfide. The condition harmless and temporary.
I hope I have answered your question. Please, feel free to ask me more in HCM if there is anything else you need to know.
Thank you, Malik Amonov MD
