Compare Plavix vs. Plavix

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Clopidogrel (Plavix) and heparin are both blood thinners, but they work differently and are used in different situations. Clopidogrel is an oral medication that prevents heart attacks and strokes by stopping platelets from clumping together. It is taken once a day and is available in a generic form. On the other hand, heparin is an injectable anticoagulant used to treat and prevent blood clots in various conditions, including deep vein thrombosis and pulmonary embolism. Heparin works quickly but requires regular blood tests to monitor its effectiveness and is typically used in hospital settings. Unlike clopidogrel, heparin has an antidote called protamine for reversing its effects in case of severe bleeding. Additionally, heparin can cause a serious condition called heparin-induced thrombocytopenia (HIT), which is not a concern with clopidogrel. While clopidogrel is taken orally, heparin is administered through injections, making it less convenient for home use.
