6. Further information
Canusal is heparinised saline which is heparin dissolved in a salt water solution.
Heparin is an anti-clotting agent and is produced naturally in the body. Canusal is used to wash and rinse the inside of intravenous catheters and cannulas (surgical forms of tubing) to ensure they do not become blocked while they are in use.
Do not use Canusal if:
• you have been told you are allergic to heparin.
Do not use Canusal if you are pregnant or trying to become pregnant without talking to your doctor first
Do not use Canusal if you are breast-feeding without talking to your doctor.
If you have any doubts about whether Canusal should be used for you then discuss things more fully with your doctor or nurse.
• Canusal should not be injected directly into the body.
• Canusal is used for cleaning catheters and cannulas (surgical forms of tubing) by flushing with 2ml (200 units) every four hours or as required.
• The doctor will decide which dose is best to be used.
• If blood for tests are to be taken from the tubing which has been rinsed with this product, the heparin in the tubing should first be withdrawn and discarded.
• Aseptic techniques should be used at all times during its use to avoid contamination.
• Your doctor will check your blood if you use Canusal for longer than five days.
Like many medicines Canusal may cause side effects in some patients, although not everybody gets them, particularly when treatment is first started.
• It can cause bleeding and occasionally a serious blood disorder (thrombocytopenia) which can cause thrombosis (clotting in the blood vessels).
• Rarely, allergic reactions can occur.
You should inform your doctor or nurse immediately if you feel unwell.

Heparin sodium 100 I.U./ml (200 I.U. in 2ml)
For excipients see 6.1
Flushing solution for maintenance of patency of intravenous devices
A colourless or straw coloured liquid, free from turbidity and from matter that deposits on standing.
Heparin is an anticoagulant and acts by potentiating the naturally occurring inhibitors of thrombin and factor X (Xa).
Canusal is indicated in any clinical circumstances in which it is desired to flush an intravenous catheter or cannula with a low concentration of heparin to ensure patency prior to administration of an intravenous injection.
Not recommended for systemic use.
For cleaning indwelling cannulae.
Material to be used as an intravascular cannula or catheter flush in doses of 200 units every 4 hours or as required.
Do not use when there is established hypersensitivity to heparin.
Caution should be exercised in patients with known hypersensitivity to low molecular weight heparins.
Rigorous aseptic technique should be observed at all times in its use.
Platelet counts should be measured in patients receiving heparin flushes for longer than five days (or earlier in patients with previous exposure to heparin). In those who develop thrombocytopenia or paradoxical thrombosis, heparin should immediately be eliminated from all flushes and ports.
Repeated flushing of a catheter device with heparin may result in a systemic anticoagulant effect.
When an indwelling device is used for repeated withdrawal of blood samples for laboratory analyses and the presence of heparin or saline is likely to interfere with or alter results of the desired blood tests, the in situ heparin flush solution should be cleared from the device by aspirating and discarding a volume of solution equivalent to that of the indwelling venipuncture device before the desired blood sample is taken.
The safety of Canusal in pregnancy is not established, but the dose of heparin involved would not be expected to constitute a hazard.
Heparin does not appear in breast milk.
Used as directed, it is extremely unlikely that the low levels of heparin reaching the blood will have any systemic effect. However, there have been rare reports of immune-mediated thrombocytopenia and thrombosis in patients receiving heparin flushes (see also Section 4.4, Special Warnings and Precautions for Use).
Keep this medicine out of the reach and sight of children.

Hypersensitivity reactions to heparin are rare. They include urticaria, conjunctivitis, rhinitis, asthma, cyanosis, tachypnoea, feeling of oppression, fever, chills, angioneurotic oedema and anaphylactic shock.
Canusal, containing only 200 I.U. of sodium heparin per ampoule (2ml), is used for flushing indwelling cannulae. This is unlikely to produce blood levels of heparin having any systemic effect.
5.3 Preclinical safety data
There are no pre-clinical data of relevance to the prescriber which are additional to those already included in other sections.
