Does clopidogrel increase bleeding risk?

In conclusion, we found that among patients receiving DES, clopidogrel use was associated with an increased risk of major bleeding over a broad range of time intervals out to 18 months. In contrast, clopidogrel use was associated with decreased risk of MI in all time intervals and death in the 7- to 12-month interval.

Is clopidogrel more expensive than aspirin?

Because clopidogrel is more costly, its incremental cost effectiveness is currently unattractive, unless its use is restricted to patients who are ineligible for aspirin.

Antiplatelets are mainly taken by people who have had a heart attack or stroke.
