Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Dabigatran (Pradaxa) and heparin are both anticoagulants, or blood thinners, used to treat and prevent blood clots, including in the legs (deep vein thrombosis (DVT)) or lungs (pulmonary embolism (PE)). However, they have some important differences. Dabigatran is a direct thrombin inhibitor available as an oral capsule and is typically taken twice a day. It does not require regular blood tests for monitoring, but it can cause stomach upset and increase the risk of bleeding. Heparin, on the other hand, is an injection and requires regular blood tests to monitor its effectiveness. It is often used in hospital settings and can cause side effects like low red blood cells and a serious condition called heparin-induced thrombocytopenia (HIT). Both medications have an antidote to reverse their effects in case of severe bleeding. Dabigatran is not recommended for people with mechanical heart valves, whereas heparin is not recommended for those with a pork allergy.

It's also used to lower the risk of stroke and blood clots in people with atrial fibrillation (AFib). The dosing can differ based on why you need the medication, but it's typically taken by mouth twice a day. Side effects include stomach upset and bleeding. For people who experience serious bleeding with this medication, there's an antidote medication called Praxbind (idarucizumab) that reverses its effects.
Summary for P2Y12 inhibitor
Prescription only
Clopidogrel (also known by its brand name, Plavix) is a medication that's used to prevent heart attack and stroke in certain people who are at higher risk for those events. It comes as a tablet taken by mouth once per day and is also available as a generic medication. Since it's a blood thinner, possible side effects include bleeding and bruising, especially if you take medications that interact with clopidogrel (Plavix) like certain antidepressants, anticoagulants, or non-steroidal anti-inflammatory drugs (NSAIDs).
