Heparin Injection

Consumer Medicine Information
 

NOTICE: This Consumer Medicine Information (CMI) is intended for persons living in Australia. This page contains answers to some common questions about Heparin Injection. It does not contain all the information that is known about Heparin Injection. It does not take the place of talking to your doctor or pharmacist. All medicines have risks and benefits. Your doctor has weighed the risk of you using this medicine against the benefits he/she expects it will have for you. If you have any concerns about using this medicine, ask your doctor or pharmacist. Bookmark or print this page, you may need to read it again.

What HEPARIN INJECTION is used for

Heparin Injection belongs to a group of medicines known as anticoagulants. Anticoagulants work by decreasing the clotting ability of your blood and help stop clots forming in the blood vessels. Anticoagulants are sometimes called "blood thinners", although they do not actually thin the blood. Heparin will not dissolve blood clots that have already formed, but it may prevent any clots that have already formed from becoming larger and causing serious problems.
Heparin Injection is used for prevention and treatment of diseases caused by blood clots such as in certain blood vessel, heart and lung conditions. It is also used to prevent blood clots from forming during surgery, dialysis or blood transfusions.
Heparin Injection may be used for the treatment of other conditions that are not mentioned above. Your doctor will be able to tell you about the specific condition for which you have been prescribed Heparin Injection.
This medicine is available only with a doctor's prescription.

How HEPARIN INJECTION is given

How it is given

Heparin Injection can be injected under the skin or into a vein. Sometimes it may be diluted and given to you as a slow injection into one of your veins (this is called an intravenous infusion). Heparin Injection must only be given by a doctor or nurse.

How much is given

Your doctor will decide what dose, how often and how long you will receive Heparin Injection. This depends on your condition and other factors, such as age, blood tests, method it is being given and whether or not other medicines are being given at the same time.
To prevent clots forming, you will usually be given a deep injection under the skin 2 hours before surgery and every 8 - 12 hours for up to a week after surgery. This will depend on your condition.
To help clots that have already formed you will be given Heparin Injection either as a continuous or intermittent infusion into the vein. Your doctor may also choose to inject Heparin Injection under the skin after giving you the first dose by an intravenous injection.

If you are given too much (overdose)

This rarely happens as Heparin Injection is administered under the care of a highly trained doctor.
However, if you are given too much heparin, you may experience some of the effects listed under "Side effects" below.
Your doctor has information on how to recognise and treat an overdose. Ask your doctor if you have any concerns.
In the case of an overdose, immediately tell your doctor or telephone the Poisons Information Centre (in Australia, phone 13 11 26; in New Zealand, phone 0800 POISON or 0800 764 766) for advice, or go to Accident and Emergency at your nearest hospital if you have side effects after being given Heparin Injection. You may need urgent medical attention.

While you are given HEPARIN INJECTION

Things you must do

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are being given Heparin Injection.
Tell any other doctors, dentists, and pharmacists who treat you that you are being given this medicine.
If you are going to have surgery, tell the surgeon or anaesthetist that you are being given this medicine.
It may affect other medicines used during surgery.
If you are about to have any blood tests, tell your doctor that you are being given this medicine.
It may interfere with the results of some tests.

Side effects

Tell your doctor or nurse as soon as possible if you do not feel well while you are being given heparin.
Like other medicines, heparin can cause some side effects. If they occur, most are likely to be minor or temporary. However, some may be serious and need medical attention.
Ask your doctor or nurse to answer any questions that you may have.
Do not be alarmed by this list of possible side effects. You may not experience any of them.
Tell your doctor or nurse as soon as possible if you notice any of the following:
change in skin colour or pain around the injection site
fever
chills
runny nose
watering eyes
nausea and vomiting
headache
itchy soles of the feet
These are side effects of heparin. Mostly these are mild and short-lived.
Tell your doctor or nurse immediately if you experience any of the following:
bleeding or bruising more easily than normal e.g. unexplained nosebleeds, heavy periods, bleeding from gums when brushing teeth
If you drink heavily you have a greater risk of bleeding compared to moderate drinkers or non drinkers. Elderly patients (older than 65 years of age), particularly women, have a greater risk of bleeding.
abdominal or stomach pain, back pain, blood in urine or stools, vomiting of blood
signs of allergy such as a rash, itching, hives on the skin, swelling of the face, lips, tongue or other parts of the body, shortness of breath, wheezing or trouble breathing
numbness, tingling or muscle weakness, abnormal function or loss of control of your bowel or urine
