When administered as an injection, the dosage and duration of treatment with heparin sodium depend on the patient’s age, weight, and response to the medication. The usual dosage for adults is 5,000-10,000 units, administered subcutaneously or intravenously every 8-12 hours. The dosage may be adjusted as needed based on the patient’s laboratory test results and the risk of bleeding.
As with any medication, heparin sodium may cause side effects in some people. Common side effects may include bleeding, bruising, and pain at the injection site. Less common side effects may include allergic reactions, low blood pressure, and osteoporosis with prolonged use.
