Synthroid and Halotestin drug interactions - a phase IV clinical study of FDA data
Summary:
Drug interactions are reported among people who take Synthroid (levothyroxine sodium) and Halotestin (fluoxymesterone). Common drug interactions include blood pressure increased among females and abdominal discomfort among males.
The phase IV clinical study analyzes what interactions people have when they take Synthroid and Halotestin. It is created by eHealthMe based on reports of 11 people who take the same drugs from the FDA, and is updated regularly.
