Clopidogrel Side Effects

Clopidogrel Side Effects, Dose, and How to Use It – Clopidogrel is a drug that serves to prevent platelets to stick together at risk of forming blood clots. Blood clots formed in arterial veins can trigger the occurrence of arterial thrombosis, such as heart attack and stroke.

Clopidogrel will be given to people who experience a heart attack, stroke, coronary heart disease, and peripheral artery disease. In certain situations such as heart attack or after the mounting of the ring at the heart, Clopidogrel will be combined with aspirin, which also serves to prevent blood clots. But keep in mind, the combination of these two drugs will make a person’s risk bleeding.

Heart attacks often occur in people with excess body weight. Why? Because when a person has an excess body weight, automatic fat deposits in their body will be more than necessary, therefore there will be an accumulation of fat in any blood vessels inside the body including in the heart (coronary blood vessels).

Fat accumulation in the coronary vein can cause narrowing of the blood vessels and also causes the surface of the veins to become brittle, when blood vessels are brittle, then the possibility of blood vessels rupturse will increase. When blood vessels rupture, a blood composition called platelet will come to “patch” the blood vessel ruptured by forming a thrombus.

How to use Clopidogrel

Take clopidogrel before or after eating according to the doctor’s direction, usually once a day. Take this medication regularly to get the maximum benefit. To help you remember, use at the same time every day.

Dosage is set based on medical conditions and response to treatment. If you use the drug to prevent blockage after the planting of tubes or other procedures, take this medication along with aspirin for months or years after the procedure (depending on the procedure/tube type) as directed by the physician.

Consult to the doctor for more details and about the risk of an early stop. It is important to continue using the drug even if you feel healthy. Do not stop taking this medication without consulting a doctor.
