Gralise and Morphine drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Gralise (gabapentin) and Morphine (morphine sulfate). Common drug interactions include nystagmus among females and weight decreased among males.

The phase IV clinical study analyzes what interactions people have when they take Gralise and Morphine. It is created by eHealthMe based on reports of 75 people who take the same drugs from the FDA, and is updated regularly.
