The anticoagulation clinics provided by Harris Health System's Department of Pharmacy, monitor and manage patients receiving anticoagulation therapy.
This clinical pharmacist-driven referral service is provided at 16 healthcare centers and two hospitals to best meet the needs of our patients. Clinical pharmacy specialists provide dose adjustments and monitor appropriate laboratory tests for anticoagulants such as warfarin (Coumadin®), enoxaparin (Lovenox®), and rivaroxaban (Xarelto®) to prevent or treat blood clots. The clinical pharmacy specialist also serves as an educational resource to patients by providing information on blood clot prevention, drug-drug interactions, drug-food interactions, and signs and symptoms of blood clots and bleeding. Using point-of-care i-STAT® machines, patients are able to obtain immediate blood levels (PT/INR) results.
