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

Summary:

Drug interactions are reported among people who take Sular (nisoldipine) and Fosrenol (lanthanum carbonate). Common drug interactions include scar among females and back pain among males.

The phase IV clinical study analyzes what interactions people have when they take Sular and Fosrenol. It is created by eHealthMe based on reports of 20 people who take the same drugs from the FDA, and is updated regularly.
