WARFARIN SODIUM in Warfarin
may interact with DEXAMETHASONE in Dexamethasone Tablets
Warfarin is generally used to prevent your blood from "coagulating" or forming blood clots. Although the cause of this potential interaction is not clearly understood, dexamethasone may alter the anticoagulant effect of warfarin. Based on information from one study and two case reports, dexamethasone may increase the anticoagulant effect of warfarin in some people and decrease its anticoagulant effect in others. This unpredictable outcome appears to be related to the individual and may also be influenced by when doses of dexamethasone and warfarin are taken. If these drugs are used at the same time, your doctor may want to monitor you closely when therapy with dexamethasone is either started or stopped. Blood tests can be used to make sure that you are getting the right amount of warfarin. If you are experiencing problems, it may be necessary to adjust the dose of warfarin. You may want to ask your healthcare provider about this potential interaction if you think you are having problems.
This interaction is poorly documented and is considered moderate in severity.
