Aspirin vs Plavix clopidogrel Differences Side Effects Bleeding Risks Benefits

Aspirin vs. Plavix (clopidogrel)

Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) used to treat fever, pain, and inflammation. It also prevents blood clots and is used to prevent heart attack and stroke. Other NSAIDs include ibuprofen (Aleve, Motrin), indomethacin (Indocin), and nabumetone (Relafen).

NSAIDs block the enzyme that makes prostaglandins, reducing inflammation, pain, and fever. Aspirin inhibits platelet function differently from other NSAIDs.

What is Plavix? How does it work?

Plavix (clopidogrel bisulfate) is an anti-platelet drug used to prevent blood clots. Plavix binds to the P2Y12 receptor on platelets, preventing platelet activation. It belongs to a class of drugs called P2Y12 inhibitors.

What are the uses for aspirin and Plavix? Can they be taken together?

Aspirin uses

Aspirin treats inflammation, fever, and pain, including those caused by arthritis, lupus, and injuries. It also reduces the risk of stroke or heart attack.
