What are blood thinners?

There are two different types of blood thinners: antiplatelet drugs and anticoagulants.

Antiplatelet drugs – Help prevent platelets in the blood from sticking together, and therefore preventing blood clots from forming.

Anticoagulants – Blood thinners that prevent existing blood clots from getting larger, and prevent new ones from forming. These are usually prescribed for people who have an irregular heartbeat (AFib), which can cause blood clots to travel from the heart to the brain.
