Antiplatelets work in various ways to prevent blood clots.

These medicines may be used instead of aspirin (which is also an antiplatelet medicine) or after a person has had a procedure (such as bypass surgery, atherectomy, or angioplasty) performed on a blood vessel.

These medicines can prevent the formation of blood clots in people who have peripheral arterial disease (PAD).¹ Antiplatelet medicines may help lower the risk of heart attack and stroke in people who have PAD.

Some side effects of these antiplatelet medicines may include:

• Stomach irritation.
• Bleeding in the stomach or intestines.
• Allergic reaction.
• Increased bruising.
• Bleeding (hemorrhage) in the brain or other internal organs.
• Lowered numbers of blood cells.

See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)

All antiplatelet medicines increase the risk of bleeding.

The best dosage and length of treatment with these medicines is still under study.
