Plavix – Clopidogrel uses, dose and side effects

}

75 mg film-coated tablets
clopidogrel

What Plavix is ​​and what it is used for

Plavix contains clopidogrel and belongs to a group of medicines called platelet inhibitors. Platelets are very small cells in the blood, which form clots (clots) during coagulation of the blood (blood clotting). By preventing this clot formation, platelet inhibitors reduce the risk of blood clots forming (a process called thrombosis or blood clot formation).

Plavix is ​​used by adults to prevent the formation of blood clots ( thrombi ) in atherosclerotic blood vessels ( arteries ), a process called atherothrombosis, which can lead to atherothrombotic events (such as stroke, heart attack, or death).

You have been given Plavix to prevent the formation of blood clots and to reduce the risk of these serious events due to:

  • You suffer from atherosclerosis (also known as atherosclerosis), and
  • You have previously had a heart attack, stroke, or are suffering from something called peripheral arterial disease, or
  • You have had severe angina ( unstable angina ) or a heart attack (heart attack). To treat this condition, your doctor may have placed a stent in the blocked or narrowed blood vessel to restore effective blood flow. You can also get acetylsalicylic acid (a substance found in many medicines used to relieve pain and lower fever and in addition to prevent the formation of blood clots) by your doctor.
  • You have had signs of a stroke that disappears within a shorter period (also called a transient ischemic attack, TIA attack/mini-stroke) or a mild ischemic stroke. You can also get acetylsalicylic acid from your doctor within the first 24 hours.
  • You have an irregular heartbeat, something called atrial fibrillation, and you can not take blood-thinning drugs that are taken orally (vitamin K antagonists ) that prevent new blood clots from forming and prevent existing blood clots from growing. You should have learned that blood-thinning drugs taken orally are more effective than acetylsalicylic acid or the combination of Plavix and acetylsalicylic acid for this disease. Your doctor should have given you Plavix and acetylsalicylic acid if you can not take blood-thinning medicines orally and you are not at risk of heavy bleeding.

What you need to know before taking Plavix

Do not take Plavix

  • If you are allergic (hypersensitive) to clopidogrel or any of the other ingredients of this medicine (listed in section 6)
  • If you suffer from any disease that causes you to have active bleeding, such as. gastric ulcer or bleeding in the brain
  • If you suffer from severe liver disease

If you have any of these symptoms or if you have any further questions, ask your doctor before taking Plavix.

Warnings and cautions

If any of the following apply to you, you should inform your doctor before taking Plavix:

  • if you are at risk of bleeding such as:
    • a disease that puts you at risk for internal bleeding (such as stomach ulcers )
    • a blood disease that puts you at risk of internal bleeding (in the body’s tissues, organs, or joints)
    • a recent serious injury
    • a recent surgery (including dental surgery)
    • a planned operation (including dental operations) within the next week
  • if you have had a blockage in an artery in your brain (ischemic stroke ) that occurred within the last week
  • if you suffer from kidney or liver disease
  • if you have had an allergy or reaction to other medicines to treat your illness
  • if you have previously had non-traumatic cerebral hemorrhage (ie not caused by external influences such as severe violence to the head)

While taking Plavix:

  • You should inform your doctor if surgery (including dental surgery) is planned.
  • You should also inform your doctor immediately if you develop a medical condition (also known as Thrombotic Thrombocytopenic Purpura or TTP) that includes fever and bruising under the skin that may occur as red pin-sized dots, with or without unexplained severe weakness, confusion, yellowing of the skin or eyes (jaundice) (see section 4 “Possible side effects”).
  • If you cut or injure yourself, it may take longer than usual for the bleeding to stop. This is linked to how your medicine works because it prevents the formation of blood clots. This normally has no significance for minor cuts and injuries such as. if you cut yourself when shaving. However, if you are concerned about your bleeding, contact your doctor immediately (see section 4 “Possible side effects”).
  • Your doctor may order blood tests.
