Interaction Details
Apixaban is classified as belonging to the following category: Anticoagulant/Antiplatelet Drugs
Theoretically, capsicum may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro research shows that capsicum might increase the effects of antiplatelet drugs. Also, population research shows that capsicum is associated with an increased risk of self-reported bleeding in patients taking warfarin. However, clinical research shows that taking a single dose of capsaicin (Asian Herbex Ltd.), the active ingredient in capsicum, 400-800 mcg orally in combination with aspirin 500 mg does not decrease platelet aggregation when compared with taking aspirin 500 mg alone. Also, there was no notable effect on measures of platelet aggregation with capsaicin. It is unclear whether capsaicin must be used in more than a single dose to affect platelet aggregation.

Apixaban Overview
-
Apixaban is used help prevent strokes or blood clots in people who have atrial fibrillation (a condition in which the heart beats irregularly, increasing the chance of clots forming in the body and possibly causing strokes) that is not caused by heart valve disease. Apixaban is also used to prevent deep vein thrombosis (DVT; a blood clot, usually in the leg) and pulmonary embolism (PE; a blood clot in the lung) in people who are having hip replacement or knee replacement surgery. Apixaban is also used to treat DVT and PE and may be continued to prevent DVT and PE from happening again after the initial treatment is completed. Apixaban is in a class of medications called factor Xa inhibitors. It works by blocking the action of a certain natural substance that helps blood clots to form.
