Black Coating On Tongue, Had Taken Pepto Bismol For Diarrhea, History Of Acid Reflux. Help?

I woke up this morning with a black coating on my tongue . I had diarrhea the night before and took pepto bismol to help relieve the diarrhea. I have acid reflux and at one time I had ulcers on the back of my tongue which caused a small amount of brown when scraping my tongue, but nothing like this dark coating that covers my entire tongue that I am scraping dark substance from the back of my tongue.

Hello,

This is probably cause of Bismol you took the other day, anyway it will clear up after a few days, no need to panic.

Hope I have answered your query. Let me know if I can assist you further.

Take care
