        • Other: Ethchlorvynol, griseofulvin, spironolactone**, sucralfate.

        • Increased bleeding tendency: (Use of these agents with oral anticoagulants may increase the chances of hemorrhage.)
        • Inhibit platelet aggregation: Cephalosporins, dipyridamole, indomethacin, oxyphenbutazone, penicillin (parenteral), phenylbutazone, salicylates, sulfinpyrazone.
        • Inhibit procoagulant factors: Antimetabolites, quinidine, quinine, salicylates.
        • Ulcerogenic drugs: Adrenal corticosteroids, indomethacin, oxyphenbutazone, phenylbutazone, potassium products, salicylates.
        • Enhanced anticoagulant effects:
