Riboflavin and Tryptophan drug interactions - a phase IV clinical study of FDA data
Summary:
Drug interactions are reported among people who take Riboflavin (riboflavin (vitamin b2)) and Tryptophan (l - tryptophan). Common drug interactions include asthma among females.
The phase IV clinical study analyzes what interactions people have when they take Riboflavin and Tryptophan. It is created by eHealthMe based on reports of 33 people who take the same drugs from the FDA, and is updated regularly.
