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

Summary:

Drug interactions are reported among people who take Razadyne (galantamine hydrobromide) and Sinemet (carbidopa; levodopa). Common drug interactions include abdominal adhesions among females and death among males.

The phase IV clinical study analyzes what interactions people have when they take Razadyne and Sinemet. It is created by eHealthMe based on reports of 20 people who take the same drugs from the FDA, and is updated regularly.
