Before you administer heparin, look at the solution closely. It should be clear and free of floating material. Gently squeeze the bag or observe the solution container to make sure there are no leaks. Do not use the solution if it is discolored, if it contains particles, or if the bag or container leaks. Use a new solution, but show the damaged one to your health care provider.

It is important that you use your medication exactly as directed. Do not change your dosing schedule without talking to your health care provider. Your health care provider may tell you to stop your infusion if you have a mechanical problem (such as a blockage in the tubing, needle, or catheter); if you have to stop an infusion, call your health care provider immediately so your therapy can continue.

Heparin may cause side effects. The most common side effect of heparin therapy is excessive bleeding (hemorrhage). If you experience any of the following symptoms, call your health care provider immediately:

• bleeding from the gums or nose
• unusually heavy menstrual bleeding
• excessive bleeding from cuts or wounds
• easy bruising
• purplish areas on the skin
• blood in urine or stools
• vomiting or coughing up blood
• chills
• fever
• itching
• rash

• Your health care provider probably will give you several days supply of heparin. You will be directed to store it in a cool, clean, dry area.
• Do not allow heparin to freeze.

Store your medication only as directed. Make sure you understand what you need to store your medication properly.

Keep your supplies in a clean, dry place when you are not using them, and keep all medications and supplies out of reach of children. Your health care provider will tell you how to throw away used needles, syringes, tubing, and containers to avoid accidental injury.
