What Is Clopidogrel Winthrop Plus Aspirin Used For?

Clopidogrel Winthrop Plus Aspirin is a combination medication that helps prevent dangerous blood clots from forming in your blood vessels.

Primary Uses

This medication is prescribed to prevent blood clots forming in hardened blood vessels (atherothrombosis) which can lead to stroke, heart attack or death. You may have been prescribed this if you have suffered from unstable angina (severe chest pain) or had a heart attack.

How It Works

The medication contains two active ingredients that work as anti-platelet medicines. Platelets are very small blood cells that clump together during blood clotting. By preventing this clumping, the medicine reduces the chances of blood clots forming in your blood vessels.

Good to know: This medication is only available with a doctor’s prescription and should be used under medical supervision.

How to Take Clopidogrel Winthrop Plus Aspirin

Take this medication exactly as prescribed by your doctor. The timing and consistency of taking your medication is important for it to work effectively.

Dosage Instructions

The usual dose is one tablet daily, containing 75 mg clopidogrel and 100 mg aspirin. You may receive a starting dose of 300 mg clopidogrel, then one tablet daily. Take the tablet during or immediately after a meal with a glass of water. Take it at about the same time each day for best results.

What If You Miss a Dose?

If you miss a dose, take it as soon as you remember. If it’s almost time for your next dose, skip the missed dose and take your next dose at the regular time. Do not take a double dose to make up for the missed dose.

Important: Never take a double dose to make up for a missed dose. Continue taking the medication for as long as your doctor prescribes it.
