What medications can contribute to ICH?
Underlying hemostatic abnormalities can contribute to ICH. Patients at risk include those taking oral anticoagulant drugs (OACs), antiplatelet agents, those with acquired or congenital coagulation factor deficiencies, and those with inherited or acquired qualitative or quantitative platelet abnormalities. Vitamin K antagonists (VKAs) such as warfarin are the most frequently prescribed OAC, but new agents that do not require laboratory monitoring and do not necessarily prolong coagulation screening tests are being increasingly used, including dabigatran.
