Transient Ischemic Attack (TIA) - Medications

Your doctor will probably prescribe several medicines after you have had a transient ischemic attack (TIA). Medicines to prevent blood clots are typically used, because blood clots can cause TIAs and strokes.

The types of medicines that prevent clotting are:

  • Antiplatelet medicines.
  • Anticoagulant medicines.

Cholesterol-lowering and blood pressure-lowering medicines are also used to prevent TIAs and strokes.

  • Clopidogrel (Plavix) may be used for people who cannot take aspirin.
