Heparin Sodium

This medication is used to keep IV catheters open and flowing freely. Heparin helps to keep blood flowing smoothly and from clotting in the catheter by making a certain natural substance in your body (anti-clotting protein) work better. It is known as an anticoagulant. This form of heparin must not be used to treat or prevent blood clots in the body. Some products should not be used in newborns due to increased risk of side effects. Check with your doctor or pharmacist for more details.

For the best possible benefit, it is important to receive each scheduled dose of this medication as directed. If you miss a dose, contact your doctor or pharmacist immediately to establish a new dosing schedule.

This medication is given by injection into the IV catheter as directed by your doctor. Do not inject this medication into the body. Heparin comes in many strengths. Serious (sometimes fatal) errors have occurred when the wrong strength was used. Check that you are using the correct strength and dose before injecting this medication. If you are giving this medication to yourself at home, learn all preparation and usage instructions from your health care professional. Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Learn how to store and discard medical supplies safely.

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval. Some products that may interact with this drug include: other drugs that can cause bleeding/bruising (e.g., anticoagulants such as warfarin, antiplatelet drugs including NSAIDS such as ketorolac), mifepristone. Check all prescription and nonprescription medicine labels carefully because many contain pain relievers/fever reducers (NSAIDs such as ibuprofen, naproxen, or aspirin) that can increase the risk of bleeding when used with heparin. Low-dose aspirin should be continued if it has been prescribed by your doctor for specific medical reasons such as heart attack or stroke prevention (usually at dosages of 81-325 milligrams per day). Consult your doctor or pharmacist for more details. Flush the catheter/line with normal saline before and after infusing drugs that interact with heparin such as doxorubicin, droperidol, ciprofloxacin, and mitoxantrone. This medication may interfere with certain laboratory tests (including prothrombin time), possibly causing false test results. Make sure laboratory personnel and all your doctors know you use this drug.
