Levothroid and Chondroitin drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Levothroid (levothyroxine sodium) and Chondroitin (chondroitin sulfate). Common drug interactions include anaemia among females and anaemia among males.

The phase IV clinical study analyzes what interactions people have when they take Levothroid and Chondroitin. It is created by eHealthMe based on reports of 11 people who take the same drugs from the FDA, and is updated regularly.
