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.
This medicine is not addictive.

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 (phone 13 11 26) 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.
Things to be careful of
Be careful driving or operating machinery until you know how Heparin Injection affects
you.
This medicine is not expected to affect your ability to drive a car or operate machinery.
However, if you experience dizziness, light-headedness, tiredness or drowsiness, do
not drive, operate machinery or do anything else that could be dangerous.
If you have any serious, physical accidents once you leave hospital, advise your treating
doctor or nurse that you have been given this medicine recently.
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 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:
any changes in skin colour or pain around the injection site, or the skin starts to
swell, gets warm/red, becomes numb or starts to blister
bleeding or bruising more easily than normal e.g. unexplained nosebleeds, heavy menstrual
periods, bleeding from gums when brushing teeth
blood in urine or stools, vomiting of blood
If you drink heavily you have a greater risk of bleeding compared to moderate drinkers
or non-drinkers. Elderly patients (older than 60 years of age), particularly women,
have a greater risk of bleeding.
abdominal or stomach pain, chest pain, irregular, fast or fluttering heartbeat, muscle
weakness or numbness in limbs, nausea and vomiting
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
