Indole-3-carbinol - Coumadin (Warfarin Sodium) Interaction

Interaction Details

Warfarin Sodium is classified as belonging to the following category: Cytochrome P450 1A2 (Cyp1A2) Substrates

There is some evidence that indole-3-carbinol induces CYP1A2 isozymes. Theoretically, indole-3-carbinol might increase the metabolism of CYP1A2 substrates and lower serum concentrations. Some substrates of CYP1A2 include clozapine (Clozaril), cyclobenzaprine (Flexeril), fluvoxamine (Luvox), haloperidol (Haldol), imipramine (Tofranil), mexiletine (Mexitil), olanzapine (Zyprexa), pentazocine (Talwin), propranolol (Inderal), tacrine (Cognex), theophylline, zileuton (Zyflo), zolmitriptan (Zomig), and others.

Interaction Details

Warfarin Sodium is classified as belonging to the following category: Anticoagulant/Antiplatelet Drugs

In vitro research shows that indole-3-carbinol inhibits platelet aggregation. Theoretically, indole-3-carbinol might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs. Some anticoagulant or antiplatelet drugs include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.

Warfarin Sodium Overview

• Warfarin is used to prevent blood clots from forming or growing larger in your blood and blood vessels. It is prescribed for people with certain types of irregular heartbeat, people with prosthetic (replacement or mechanical) heart valves, and people who have suffered a heart attack. Warfarin is also used to treat or prevent venous thrombosis (swelling and blood clot in a vein) and pulmonary embolism (a blood clot in the lung). Warfarin is in a class of medications called anticoagulants ('blood thinners'). It works by decreasing the clotting ability of the blood.
