Vile/ October 2, 2012/ Aleve & Naproxen
Fibrates The use of fibrates alone is occasionally associated with myopathy; use with statins may increase this risk.
A year-old man receiving a stable maintenance dosage of warfarin experienced an increased international normalized ratio INR without bleeding when his atorvastatin therapy was switched to fluvastatin. Careful monitoring is therefore needed, and maximum daily dose of simvastatin is 10 mg daily when used with fibrates except fenofibrate. This tool may not cover all possible drug interactions.

Home Drug Safety Update. Substrate kinetics of warfarin and pure enantiomers were performed with human liver microsomes to determine the kinetic parameters Km and Vmax for the formation of all 6 hydroxywarfarin metabolites, inhibition of warfarin metabolism in the presence of statins, was determined.
Monitor Closely Significant interaction possible monitoring by your doctor required. Available for Android and iOS devices.
Caution is needed with ciclosporin, erythromycin, and clarithromycin. For rosuvastatin, start with 5 mg and do not exceed 20 mg during use with fibrates. Add to My Bibliography.
The fluvastatin was switched back to atorvastatin, and the warfarin dosage was increased to maintain the patient's goal INR.

Monitor INR before starting treatment and regularly during treatment, especially with dose changes. It is unclear whether simvastatin interacts with warfarin, but it may increase INRs slightly or increase serum simvastatin levels.
