What is Amicar (aminocaproic acid)?
Aminocaproic acid is a man-made form of a protein that occurs naturally in the body and helps the blood to clot.

Aminocaproic acid is also used to prevent bleeding after heart surgery or placement of a shunt near the liver to control high blood pressure.

You may be shown how to use an IV at home. Do not give yourself this medicine if you do not understand how to use the injection and properly dispose of needles, IV tubing, and other items used.
You should start using this medicine at the first sign of a bleeding episode. You may need to first use the injection form and then use an oral form (tablet or liquid). Your first dose may be much higher than the doses you use later on. Follow your doctor's dosing instructions very carefully.
Treatment with aminocaproic acid is usually continued hourly for 8 hours or until the bleeding has stopped.
Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.
The injectable form of aminocaproic acid must be mixed with a liquid (diluent) before using it. If you are using the injections at home, be sure you understand how to properly mix and store the medicine.
Do not use the injectable medicine if it has changed colors or has particles in it. Call your pharmacist for new medicine.
Use a disposable needle and syringe only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.
Call your doctor promptly if your symptoms do not improve after using aminocaproic acid.
While using aminocaproic acid, you may need frequent blood tests. Your kidney function may also need to be checked. Aminocaproic acid can have long-lasting effects on your body. You may need frequent medical tests for a short time after you stop using this medicine.
Store at cool room temperature away from moisture and heat. Do not allow the medicine to freeze.
