Tenormin and Lactobacillus drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Tenormin (atenolol) and Lactobacillus (lactobacillus). Common drug interactions include diarrhoea among females and bursitis among males.

The phase IV clinical study analyzes what interactions people have when they take Tenormin and Lactobacillus. It is created by eHealthMe based on reports of 21 people who take the same drugs from the FDA, and is updated regularly.
