Patient Medication Information: uses, side effects, how to take - Heparin Sodium Injection USP (Sterinova)
ABOUT THIS MEDICATION
What the medication is used for
Heparin Sodium Injection is indicated for subcutaneous use only in:
- preventing the spread of blood clots in your veins
- preventing the spread of blood clots to your lungs
- preventing blood clots complications associated to your heart
- prevention of blood clots in your arteries
What it does
Heparin stops reactions that lead to the clotting of blood and the formation of clots. Once an active blood clot has developed, larger amounts of heparin can inhibit further clotting.
Peak levels of heparin are achieved 2-4 hours following intravenous administration, although there are considerable individual variations.
When it should not be used
BEFORE you use Heparin Sodium Injection, talk to your doctor if you have:
- severe reduction of blood platelets
- an uncontrollable active bleeding state (see WARNINGS AND PRECAUTIONS), except when this is due to disseminated intravascular coagulation
- a hypersensitivity or allergy to this drug or to any ingredient in the formulation or component of the container. For a complete listing, see What the important nonmedicinal ingredients are.
What the medicinal ingredient is
Heparin sodium
What the important nonmedicinal ingredients are

What dosage form it comes in
Heparin Sodium Injection is available as 5 000 USP units per 0.5 mL, single dose, supplied in prefilled glass syringes fitted with a 27G - ½ inch needle suitable for subcutaneous injection and a needle safety device.
WARNINGS AND PRECAUTIONS
Bleeding can occur at virtually any site in patients receiving heparin.
Increased resistance to heparin is frequently encountered in fever, blood clot, vein inflammation associated with a blood clot, infection with blood clotting tendencies, heart attack, cancer and in patients after surgery.
Heparin sodium should be used with extreme caution in disease states in which there is increased danger of bleeding. Some of the conditions in which increased danger bleeding exists are:
- Infections of the heart and heart valves. Severe high blood pressure.
- During and immediately following (a) spinal tap or spinal anesthesia or (b) major surgery, especially involving the brain, spinal cord, or eye.
- Conditions associated with increased bleeding tendencies, such as hemophilia, thrombocytopenia (low platelets) and some vascular purpuras.
- Ulcers of the stomach and continuous tube drainage of the stomach or small intestine.
- Menstruation, liver disease with impaired blood clotting.
Heparin sodium should be used with caution in patients at risk of increased potassium levels.
Excessive administration of potassium-free solutions may result in significant low concentrations of potassium in the blood.
Heparin is not intended for Intramuscular Use.
Allergic reaction to this drug might happen, stop the medication and consult your doctor.
