What this medicine is used for
The name of your medicine is Ketamine Apotex solution for injection. It contains the active ingredient ketamine hydrochloride.
Ketamine is used to make the body insensitive to surgical treatment. It may be used in combination with other medicines to induce anaesthesia.
How it works
Ketamine belongs to a group of medicines called anaesthetics.
It works by stopping the brain from interpreting messages of pain.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.
This medicine is addictive.
Individuals with a history of drug abuse or dependence may develop ketamine dependence and tolerance; however, addiction is unlikely to occur when ketamine is used as prescribed for anaesthesia.
This medicine is available only with a doctor's prescription.

How this medicine is given
How much is given
Your doctor will decide what dose you will receive. This depends on your condition and other factors, such as your age, weight and other medicines that are being given.
How it is given
Ketamine is given as an injection into a muscle, or as a slow injection into a vein. It must only be given by a nurse or doctor.
If you receive too much (overdose)
As ketamine is given to you in a hospital under the supervision of your doctor, it is very unlikely that you will receive an overdose. You will be closely monitored in hospital during the early post-operative period so that any unwanted side effects can be treated. However, if you experience severe side effects tell your doctor immediately.
Symptoms of an overdose may include the side effects listed below in the 'Possible Side Effects' section but are usually of a more severe nature.
In the case of an overdose, immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice. Alternatively, go to the Accident and Emergency department at your nearest hospital.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

Things to be careful of
Be careful driving or operating machinery or engage in hazardous activities for at least 24 hours after receiving ketamine.
When ketamine is used on an outpatient basis, you should not be released from medical care until you have completely recovered from the anaesthesia, and then you should be accompanied by a responsible adult.
Do not drink alcohol for 24 hours after you have been given this medicine.

Tell your doctor or nurse as soon as possible if you do not feel well when you are given ketamine.
