It is natural for the body to form blood clots when an injury occurs and there is bleeding. This is nature's way of preventing the body from bleeding to death. Sometimes blood clots form when they not necessary. Blood clots, or thromboembolisms, occur in either the superficial or deep veins, usually in the legs or pelvis. These clots can break free and lodge in the pulmonary vasculature, causing a pulmonary embolism that can be lethal. Clotting also occurs in the arteries and can cause strokes or heart attacks.
Low Molecular Weight Heparin
Until recently, heparin had to be given through the veins. This medication was only administered in the hospital through an IV. Daily blood tests were needed to make sure the blood did not become too thin. Now with the advent of low molecular weight heparin or Lovenox, heparin therapy can be self injected subcutaneously, according to MayoClinic.com. This drug, which is used to prevent deep vein blood clots, does not need daily blood testing and eliminates the need for prolonged stays in the hospital. It can be injected two to three times daily and requires a prescription from a physician.
Plavix
Plavix, or clopidogrel bisulfate, is an oral medication given to patients who have a history of heart attack or stroke, according to the National Institutes of Health. It is also used in patients with unstable angina. Plavix works by preventing platelets in the blood from clumping together in the arteries. Patients who have had bleeding ulcers must be careful when taking this medication, as it can cause a recurrence of the bleeding. Plavix 75 mg is an oral medication usually taken once a day.
Aspirin
According to MayoClinic.com, aspirin therapy can also help prevent clots that cause heart attacks or strokes. A doctor who knows the patient's condition can decide if aspirin therapy is the right treatment. The doctor may prescribe a dose from 81 mg to 325 mg, depending on different factors such as age, past medical history and weight. Aspirin can cause bleeding from stomach ulcers and ringing in the ears. Patients with asthma should avoid aspirin.
