Halothane and Forane drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Halothane (halothane) and Forane (isoflurane). Common drug interactions include anaphylactic reaction among females.

The phase IV clinical study analyzes what interactions people have when they take Halothane and Forane. It is created by eHealthMe based on reports of 6 people who take the same drugs from the FDA, and is updated regularly.
