Simvastatin and Theophylline drug interactions - a phase IV clinical study of FDA data
Summary:
Drug interactions are reported among people who take Simvastatin (simvastatin) and Theophylline (theophylline). Common drug interactions include anti-erythropoietin antibody positive among females and dyspnoea among males.
The phase IV clinical study analyzes what interactions people have when they take Simvastatin and Theophylline. It is created by eHealthMe based on reports of 823 people who take the same drugs from the FDA, and is updated regularly.
