Clopidogrel, commonly known by its brand name Plavix, is a prescription medication used to prevent blood clots in conditions such as chest pain, peripheral artery disease, heart attack, or stroke. Its effectiveness in preventing clots makes it a crucial part of treatment plans for patients at risk of cardiovascular events.
Clopidogrel is often prescribed for individuals who have a history of heart conditions or have undergone procedures like stent placement. By inhibiting platelet activation and aggregation, Clopidogrel helps prevent thrombus formation, reducing the risk of heart attacks and strokes.
What is Clopidogrel?
Clopidogrel is a prescription medication available as a Plavix brand-name drug and as a generic drug. However, in certain cases, it may not be available as a brand-name drug in all strengths or forms.
Clopidogrel is only available as an oral tablet, which is typically taken once daily. The medication works by targeting specific platelets in the blood, preventing them from aggregating and forming clots.
What Are the Uses of Clopidogrel?
Clopidogrel is used to prevent blood clots in conditions like chest pain, peripheral artery disease, heart attack, or stroke. It may be part of combination therapy, requiring additional medications like aspirin, as determined by your doctor.
Clopilet action involves inhibiting platelet activation and aggregation, which helps prevent thrombus formation. By preventing clot formation, Clopidogrel reduces the risk of cardiovascular events and improves patient outcomes.
Conditions Clopidogrel Treats
Preventing blood clots in conditions such as chest pain, peripheral artery disease, heart attack, or stroke.
Part of combination therapy with aspirin for patients with a history of heart conditions or after stent placement.
Secondary Uses of Clopidogrel
Clopidogrel and aspirin tablets are used in combination to prevent blood clots in patients with acute coronary syndrome or those undergoing procedures like stent placement.
Clopidogrel tablet uses include preventing clot formation in patients with a history of heart attack or stroke. Additionally, Clopidogrel may be prescribed for patients with a history of transient ischemic attack (TIA) or those at risk of cardiovascular events.
How Does Clopidogrel Work?
Clopidogrel is classified as a platelet inhibitor or P2Y12 ADP platelet receptor inhibitor of the thienopyridine class. Clopidogrel mechanism of action involves selectively and irreversibly inhibiting the binding of adenosine diphosphate (ADP) to its platelet receptor, thus preventing platelet activation and aggregation. This action helps prevent the formation of blood clots, reducing the risk of heart attacks and strokes.
Clopidogrel Dosage
Clopidogrel tablet dosage typically involves taking the medication orally once daily, with or without food, as directed by your doctor. Take it regularly at the same time each day to maximize its benefits. The dosage and duration of treatment may vary based on the patient's medical condition and response to treatment.
Typical Dosage Instructions
Commonly, Clopidogrel 75 mg once daily.
A higher "loading dose" may be given initially for certain acute conditions like a heart attack.
If prescribed with aspirin (e.g., after a stent), take both medications as directed.
Do not stop taking Clopidogrel abruptly without consulting your doctor, even if you feel well, as this can increase your risk of clots.
What Should I Do If I Miss a Dose of Clopidogrel?
If you miss a dose, take it as soon as you remember. If it is near the time of the next dose, skip the missed dose and resume your usual dosing schedule. Do not take a double dose to make up for the missed dose, as this may increase the risk of bleeding.
What Happens if an Overdose?
Symptoms of overdose may include unusual bruising or bleeding. If overdose is suspected, seek immediate medical attention. Overdose can lead to severe bleeding complications, which can be life-threatening if left untreated.

It is sold under the brand names Ecosprin, Sprin, Aspro, Eprin, and Delisprin.
Formula: C16H16ClNO2S·HCl
Formula: C9H8O4
Clopidogrel is used for preventing blood clots when you have chest pain, peripheral artery disease, poor circulation in your legs, heart attack, or stroke.
It is a medication used for reducing pain, fever, or inflammation.
Clopidogrel is used for preventing blood clots in conditions like chest pain, peripheral artery disease, heart attack, or stroke. It may be used with other medications as determined by your doctor.
Clopidogrel is usually best taken in the morning, with or without food, as directed by your doctor.
Aspirin and clopidogrel are both used to prevent blood clots, but they work differently. Aspirin is a pain reliever and anti-inflammatory drug, while clopidogrel is an antiplatelet medication that specifically prevents blood clots.
You're not likely to have blood pressure changes while you're taking Plavix. However, sudden drops in blood pressure may be a symptom of severe internal bleeding, which is a possible side effect of Plavix.
You may notice that you bruise or bleed more easily and that it will take longer to stop bleeding while you are taking clopidogrel. This shows that clopidogrel is still working. However, if bleeding is excessive or prolonged, or if you notice blood in your urine or stool, seek emergency medical advice.
Arthralgia and back pain are also known to occur when used. There have been case reports linking arthritis to the use of clopidogrel.
Clopidogrel usually does not affect the kidneys, as it is primarily metabolized in the liver and does not pose direct risks to kidney function.
Clopidogrel is more effective than aspirin if one is willing to accept a single paradigm of atherosclerosis. However, the benefit is modest: about 200 patients should use clopidogrel rather than aspirin for 1 year to prevent just one vascular event.
Other adverse gastrointestinal effects reported in patients receiving clopidogrel include GI discomfort, diarrhoea, constipation, dyspepsia, nausea, and abdominal pain, although the incidence is not known.
