Sinemet and Divalproex drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Sinemet (carbidopa; levodopa) and Divalproex (divalproex sodium). Common drug interactions include intervertebral disc degeneration among females and balance disorder among males.

The phase IV clinical study analyzes what interactions people have when they take Sinemet and Divalproex. It is created by eHealthMe based on reports of 64 people who take the same drugs from the FDA, and is updated regularly.

How the study uses the data?

The study uses data from the FDA. It is based on carbidopa; levodopa and divalproex sodium (the active ingredients of Sinemet and Divalproex, respectively), and Sinemet and Divalproex (the brand names). Other drugs that have the same active ingredients (e.g. generic drugs) are not considered. Dosage of drugs is not considered in the study.

How to use the study?
