Peptobismol and increased fluid intake!
Hi and thanks so much for this query.
I am so sorry to hear about what your husband is experiencing. I recommend he drinks more water and also takes peptobismol for symptoms relief. I caution against taking any antidiarrheal medication such as loperamide
as this is not appropriate though commonly used.
I hope this guides and helps. I wish your husband well. Feel free to follow up with me if need be.
