Colchicine and Tamiflu drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Colchicine (colchicine) and Tamiflu (oseltamivir phosphate). Common drug interactions include neurogenic bladder among females and chronic kidney disease among males.

The phase IV clinical study analyzes what interactions people have when they take Colchicine and Tamiflu. It is created by eHealthMe based on reports of 92 people who take the same drugs from the FDA, and is updated regularly.
