Drugs that Interact with Antara (fenofibrate)

Coumarin Anticoagulants

Antara may potentiate the anticoagulant effects of coumarin-type anticoagulants. Dosage reduction is advised to maintain desired PT/INR levels and prevent bleeding complications.

Immunosuppressants

Immunosuppressants like cyclosporine and tacrolimus can cause nephrotoxicity and decrease creatinine clearance. Careful consideration of benefits and risks is necessary when using Antara with immunosuppressants.

Bile-Acid Binding Resins

Bile-acid binding resins should be taken at least 1 hour before or 4 to 6 hours after Antara to avoid impeding its absorption.

Colchicine

Co-administration of fenofibrates with colchicine may cause myopathy, including rhabdomyolysis. Caution should be exercised when prescribing fenofibrate with colchicine.
