Your doctor will probably prescribe several medicines after you have had a stroke. Medicines to prevent blood clots are typically used, because blood clots can cause TIAs and strokes.
The types of medicines that prevent clotting are:
Cholesterol-lowering and blood-pressure–lowering medicines are also used to prevent TIAs and strokes.
Anticoagulants such as warfarin (for example, Coumadin) prevent blood clots from forming and keep existing blood clots from getting bigger.
You may need to take this type of medicine after a stroke if you have atrial fibrillation or another condition that makes you more likely to have another stroke. For more information, see the topic Atrial Fibrillation.
