التداخل بين تحت سترات البزموت وميترونيدازول وتتراسيكلين وهيبارين

Metronidazole has been reported to potentiate the anticoagulant effect of warfarin, and other oral coumarin anticoagulants, resulting in a prolongation of prothrombin time.

Anticoagulants: Potentiation of the anticoagulant effect; Prothrombin time, International Normalized Ratio (INR), or other suitable anticoagulation tests should be closely monitored.

Anticoagulants Bismuth subcitrate potassium, metronidazole and tetracycline hydrochloride may alter the anticoagulant effects of warfarin and other oral coumarin anticoagulants.

Other Interactions Digitalis, tetracyclines, nicotine, or antihistamines, or intravenous nitroglycerin may partially counteract the anticoagulant action of heparin sodium.
