Patients with blood clots may be able to cut the number of medications they have to take in half. While blood clots are usually treated with two medications, new research suggests that one treatment may be just as effective and safe in treating them.

Following a blood clot patients commonly take warfarin (Coumadin) to prevent a recurrence. It may be just as safe and effective for those individuals to later switch to aspirin.

Patients with certain types of atrial fibrillation, a common heart arrhythmia, are at a high risk of stroke and blood clots if they temporarily stop their blood thinning medication before surgery or permanently because of side effects.
