Gabapentin and Tambocor drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Gabapentin (gabapentin) and Tambocor (flecainide acetate). Common drug interactions include asthenia among females and pneumonia among males.

The phase IV clinical study analyzes what interactions people have when they take Gabapentin and Tambocor. It is created by eHealthMe based on reports of 31 people who take the same drugs from the FDA, and is updated regularly.
