Heparin Vials (Heparin Sodium, Porcine)

Indications

Heparin is used to prevent the formation of blood clots in patients with certain medical conditions or those undergoing certain medical procedures that increase their risk of clot formation. It can be used to halt the growth of clots already present in the blood vessels, but it cannot reduce the size of already-existing clots. It is classified as an anticoagulant medication or "blood thinner".

Heparin works by binding to antithrombin III (ATIII) and greatly accelerating the rate at which ATIII inactivates coagulation enzymes thrombin (factor IIa) and factor Xa, which are involved in blood clotting. This prevents the formation of blood clots in the body, which can lead to a variety of serious medical conditions, such as deep vein thrombosis, pulmonary embolism, and stroke.

Use and Dosage

Heparin is available in vials. It is injected one to six times a day and sometimes given as a slow, continuous injection into the vein directed by a healthcare provider. When heparin is used to prevent blood clots from forming in intravenous catheters, it is usually used when the catheter is first put in place, and every time that blood is drawn out of the catheter or medication is given through the catheter.

Heparin is typically administered by injection either intravenously or subcutaneously, and the dosage and duration of treatment may vary depending on the patient's medical condition and response to therapy. Follow the healthcare provider's instructions carefully and report any unusual side effects or bleeding immediately.

Heparin should not be injected into a muscle. The dosage and frequency of administration are determined based on the patient's medical condition, weight, and response to treatment. If heparin is injected into a vein, flush the catheter/line with normal saline before and after infusing medications that may interact with heparin, such as doxorubicin, droperidol, ciprofloxacin, and mitoxantrone.

Cautions

• Extreme caution is required to avoid medication errors, as there are numerous concentrations available.
• Heparin sodium may prolong one-stage prothrombin time, so close monitoring of blood clotting parameters is necessary.
• Heparin may increase the risk of bleeding, so it should be used with caution in patients with bleeding disorders or a history of bleeding.
• Uncontrollable active bleeding is a contraindication to heparin use.
• Extra caution should be observed in the administration of heparin lock solutions to prevent accidental overdose or underdose.
• Heparin should be used with caution in patients with hypertension, as it may increase blood pressure.
• Pork allergy is a potential risk for patients who are allergic to pork products. Heparin is derived from the porcine intestinal mucosa.
• Heparin may cause thrombocytopenia, which is a dangerous decrease in platelet count that increases the risk of bleeding. Blood cell counts should be monitored regularly.
• Heparin should be used with caution in patients with liver or kidney dysfunction, as it may increase the risk of bleeding or other adverse effects.
• Heparin may interact with other medications, including antiplatelet drugs, fibrinolytic, and nonsteroidal anti-inflammatory drugs (NSAIDs). Healthcare providers should review all medications and drug history prior to initiating heparin therapy.
• Risk of spinal/epidural hematoma in patients with neuraxial anesthesia or undergoing spinal puncture while on heparin therapy.
• Heparin flushes are contraindicated in premature infants (less than 1500 grams birthweight) because of the benzyl alcohol content.
• The potential harm of heparin to a developing fetus during pregnancy is unclear; heparin should be used during pregnancy only if clearly needed and when the potential benefits outweigh the potential risks.
