Fosrenol and Valcyte drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Fosrenol (lanthanum carbonate) and Valcyte (valganciclovir hydrochloride). Common drug interactions include urinary incontinence among females and nephrogenic anaemia among males.

The phase IV clinical study analyzes what interactions people have when they take Fosrenol and Valcyte. It is created by eHealthMe based on reports of 21 people who take the same drugs from the FDA, and is updated regularly.
