What Is Plavix (Clopidogrel)? Uses, Dosage, and What You Need to Know in 2026

If your doctor has just prescribed Plavix (or its generic, clopidogrel), you probably have questions. What does it do? How do you take it? How long will you need it? This guide answers the most important questions so you can start your treatment with confidence.

What Is Plavix (Clopidogrel)?

Plavix is the brand name for clopidogrel bisulfate, an antiplatelet medication manufactured by Sanofi-Aventis. It was first approved by the FDA in 1997 and has become one of the most widely prescribed medications in the world. Generic clopidogrel has been available since 2012 after Plavix's patent expired.

Clopidogrel belongs to a class of drugs called P2Y12 platelet inhibitors (or thienopyridines). It prevents blood clots by stopping platelets — small blood cells — from sticking together to form dangerous clots inside arteries.

What Is Clopidogrel Used For?

Clopidogrel has several FDA-approved uses:

• After a heart attack or unstable angina: Clopidogrel (usually combined with aspirin) reduces the risk of additional heart attacks, stroke, and cardiovascular death in patients with acute coronary syndrome (ACS).
• After a coronary stent (PCI): Clopidogrel plus aspirin (dual antiplatelet therapy, or DAPT) is essential for preventing stent thrombosis — a life-threatening clot inside the stent. Duration is typically 6-12 months.
• After a stroke or TIA: Clopidogrel reduces the risk of a future ischemic stroke in patients who have had a prior stroke or mini-stroke (TIA). It is used as secondary prevention.
• Peripheral arterial disease (PAD): Clopidogrel reduces major adverse cardiovascular events in patients with symptomatic PAD. The 2024 ACC/AHA PAD guidelines endorse it as a first-line antiplatelet agent.

Clopidogrel Dosage: How Do You Take It?

Clopidogrel comes in two tablet strengths:

• 75 mg tablet: The standard maintenance dose. Taken once daily, with or without food.
• 300 mg tablet: Used as a loading dose in acute situations — such as before or during a PCI procedure — to rapidly achieve platelet inhibition. Sometimes 600 mg (two 300 mg tablets) is used for faster loading.

For most patients on long-term therapy: take your 75 mg tablet at the same time each day. You can take it with or without food. If you are also taking aspirin, take it as directed by your doctor — do not stop aspirin without checking first.

What Happens If You Miss a Dose?

If you miss a dose, take it as soon as you remember. If it is almost time for your next scheduled dose, skip the missed dose and continue with your regular schedule. Do not double up doses. If you miss multiple doses or are running out of medication, contact your prescriber immediately.

How Long Will You Need to Take Clopidogrel?

The duration depends on why you are taking it:

• After a drug-eluting stent: typically 6-12 months of dual antiplatelet therapy (DAPT), sometimes longer for high-risk patients
• After a bare metal stent: at least 1 month of DAPT
• After a stroke or TIA: often long-term (years), sometimes indefinitely
• For PAD: often indefinitely as long as it is well tolerated

Never stop clopidogrel without your doctor's approval — even if you feel fine. The risk of stopping prematurely can be severe.

Important Things to Tell Your Doctor Before Starting

• All other medications you take — especially omeprazole, esomeprazole, NSAIDs, warfarin, SSRIs, or repaglinide
• Any history of bleeding disorders, stomach ulcers, or intracranial hemorrhage
• Any planned surgeries, dental procedures, or invasive tests
• Whether you are pregnant, planning to become pregnant, or breastfeeding
