Levoxyl and Klonopin drug interactions - a phase IV clinical study of FDA data
Summary:
Drug interactions are reported among people who take Levoxyl (levothyroxine sodium) and Klonopin (clonazepam). Common drug interactions include back pain among females and hypersensitivity among males.
The phase IV clinical study analyzes what interactions people have when they take Levoxyl and Klonopin. It is created by eHealthMe based on reports of 474 people who take the same drugs from the FDA, and is updated regularly.
