Boric acid and Synthroid drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Boric acid (boron) and Synthroid (levothyroxine sodium). Common drug interactions include basedow's disease among females and surgery among males.

The phase IV clinical study analyzes what interactions people have when they take Boric acid and Synthroid. It is created by eHealthMe based on reports of 16 people who take the same drugs from the FDA, and is updated regularly.
