Aminocaproic Acid Injection

Description

Aminocaproic acid injection is used to control bleeding that occurs when blood clots are broken down too quickly. This type of bleeding may occur during or after heart or liver surgery; in people who have certain bleeding disorders; in people who have cancer of the prostate (a male reproductive gland), lung, stomach, or cervix (opening of the uterus); and in pregnant women experiencing placental abruption. Aminocaproic acid can also be used to treat the overdose and/or toxic effects of the thrombolytic pharmacologic agents tissue plasminogen activator (commonly known as tPA) and streptokinase.

For the treatment of acute bleeding syndromes due to elevated fibrinolytic activity, it is suggested that 16 to 20 mL (4 to 5 g) of Aminocaproic Acid Injection,  in 250 mL of diluent be administered by infusion during the first hour of treatment, followed by a continuing infusion at the rate of 4 mL (1 g) per hour in 50 mL of diluent. This method of treatment would ordinarily be continued for about 8 hours or until the bleeding situation has been controlled.

Additional Information

Aminocaproic acid injection comes as a solution (liquid) to be injected into a vein by a doctor or nurse in a hospital or clinic or by the patient at home. It is usually injected over about 8 hours as needed to control bleeding.

If you are using aminocaproic acid at home and you miss a dose, inject the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not inject a double dose to make up for a missed one.
