70 Year Old Female, Currently Being Treated For MS With
Peptobismol is appropriate for temporary treatment.
Hello and welcome to "Ask a Doctor " service.
I have read your query and here is my advice.
Yes, peptobismol is an appropriate treatment for temporary relief from stomach problems accompanied by nausea and even diarrhea.
However, if the symptoms persist or get worse it is advisable to see a Doctor and to get proper treatment.
It is probably a stomach flu that has caused those symptoms and there seem no relation with MS.
Hope you found the answer helpful.
Let me know if I can assist you further.
