Verapamil hcl and Seroquel drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Verapamil hcl (verapamil hydrochloride) and Seroquel (quetiapine fumarate). Common drug interactions include cystitis among females and hypoglycaemia among males.

The phase IV clinical study analyzes what interactions people have when they take Verapamil hcl and Seroquel. It is created by eHealthMe based on reports of 36 people who take the same drugs from the FDA, and is updated regularly.
