Who should not take Plavix
A contraindication is a condition under which Plavix (Clopidogrel) should not be taken because the risk outweighs the benefit. Plavix has both absolute contraindications (do not use) and relative cautions (use only after careful review). This page summarises both at the 75mg, 300mg dosing range.
Absolute contraindications
According to the prescribing information for Clopidogrel, absolute contraindications typically include severe allergic reactions to the active ingredient or excipients, severe hepatic or renal impairment, certain cardiovascular conditions, and concurrent use of specific interacting medications. The exact list depends on the molecule and is detailed in the official label.
Relative cautions
Relative cautions are situations where Plavix can be used but with extra monitoring, dose reduction or alternative considered. These often include mild-to-moderate organ impairment, age extremes, multiple comorbidities, and complex medication regimens. After absorption, clopidogrel is converted in the liver to an active metabolite that irreversibly binds the P2Y12 ADP receptor on platelets.
