What is in this leaflet

It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

What OxyContin tablets are taken for
OxyContin tablets contain oxycodone hydrochloride. Oxycodone belongs to a group of medicines called opioid analgesics.
OxyContin tablets are used to relieve moderate to severe chronic pain when other forms of treatment have not been effective.
Your doctor, however, may prescribe it for another purpose.
Ask your doctor if you have any questions about why it has been prescribed for you.
As with all strong painkillers, your body may become used to you taking OxyContin tablets. Taking it may result in physical dependence. Physical dependence means that you may experience withdrawal symptoms if you stop taking OxyContin tablets suddenly, so it is important to take it exactly as directed by your doctor.
This medicine is only available with a doctor's prescription.
Before you take it
Long-term use of OxyContin tablets may result in a decrease in sex hormone levels which may affect sperm production in men and the menstrual cycles in females. Talk to your doctor if you have concerns.
When you must not take it
Do not take OxyContin tablets if you:
- have any breathing problems such as acute asthma, respiratory depression (breathing slows or weakens) or other obstructive airways disease
- are severely drowsy or have a reduced level of consciousness

Do not take OxyContin tablets if you are allergic to oxycodone, opioid painkillers, or any of the ingredients listed at the end of this leaflet.
Do not take this medicine after the expiry date (EXP) printed on the pack. If you take it after the expiry date has passed, it may not work very well.

How much to take
Your doctor will tell you exactly how much to take.
Follow the instructions given to you by your doctor and pharmacist exactly.
How to take it
Swallow OxyContin tablets whole with a full glass of water or other fluid.
OxyContin tablets should be taken one tablet at a time with enough water to ensure complete swallowing immediately after placing it in the mouth.
Do not pre-soak, lick or wet the tablet before placing in your mouth.
Do not break, cut, chew, crush or dissolve the tablets. OxyContin tablets are only designed to work properly if swallowed whole. The tablets may release all their contents at once if broken, cut, chewed, crushed or dissolved which can be dangerous and cause serious problems, such as an overdose, which may be fatal.
If you have trouble swallowing your tablets whole, talk to your doctor.
You must only take OxyContin tablets by mouth. Taking this medicine in a manner other than that prescribed by your doctor can be harmful to your health.
There are no data on rectal administration of OxyContin tablets, therefore rectal administration of OxyContin tablets is not recommended.
When to take it
Take OxyContin tablets every 12 hours.
Take OxyContin tablets regularly to control the pain. Taking them at the same time each day will assist in ensuring the best effect in improving your pain. If however, you begin to experience worsening pain and you are taking your OxyContin tablets as prescribed, contact your doctor as your dosage may have to be reviewed.
How long to take it
Continue taking your medicine for as long as your doctor tells you.
If you stop taking this medicine suddenly, your pain may worsen and you may experience withdrawal symptoms such as:
- body aches
- loss of appetite, nausea, stomach cramps or diarrhoea
- fast heart rate
- sneezing or runny nose
- chills, tremors, shivering or fever
- trouble sleeping
- increased sweating and yawning
- nervousness or restlessness.
If you forget to take it
If you forget to take your tablets, contact your doctor or pharmacist for advice.
Do not take a double dose to make up for the dose you have missed. This will increase the chance of you getting unwanted side effects.
If you have trouble remembering when to take your medicine, ask your pharmacist for hints. For example, take your medicine at the same time each morning and evening such as 8 a.m. and 8 p.m.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (Australia: telephone 13 11 26) for advice, or go to Accident and Emergency at your nearest hospital, if you think you or anyone else may have taken too many OxyContin tablets.
Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
You should also follow the above steps if someone other than you has accidentally taken the tablets that were prescribed for you.
Keep telephone numbers for these places handy.
If someone takes an overdose they may experience difficulties in breathing, become drowsy and tired, lack muscle tone, have cold or clammy skin, have constricted pupils, have very low blood pressure or slow heart rate and may even become unconscious or die.
When seeking medical attention, take this leaflet and any remaining tablets with you to show the doctor. Also tell them about any other medicines or alcohol which have been taken.
While you are taking it
Things you must do
Take OxyContin tablets exactly as your doctor has prescribed.
Before you start on a new medicine, remind your doctor and pharmacist that you are taking OxyContin tablets.
Tell any other doctors, dentists and pharmacists who treat you that you are taking this medicine.
If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine. It may affect other medicines used during surgery.
If you become pregnant while taking this medicine, tell your doctor immediately.
Keep all of your doctor's appointments so that your progress can be checked. Tell your doctor if your pain is getting worse. Also tell your doctor if you are having any problems or difficulties while you are being treated with OxyContin tablets.
Tolerance to oxycodone may develop which means that the effect of the medicine may decrease. If this happens, your doctor may review your dose so that you get adequate pain relief.
Keep enough OxyContin tablets with you to last over weekends and holidays.
Things you must not do
Do not drink alcohol while you are taking OxyContin tablets. Drinking alcohol whilst taking OxyContin tablets may make you feel more sleepy and increase the risk of serious side effects, such as shallow breathing with the risk of stopping breathing and loss of consciousness.
Do not take OxyContin tablets to treat any other complaint unless your doctor tells you to.
Do not give your medicine to anyone else, even if they have the same condition as you.
Do not stop taking your medicine, exceed the dose recommended or change the dosage without checking with your doctor. Over time your body may become used to oxycodone. If you stop taking it suddenly, your pain may worsen and you may experience unwanted side effects such as withdrawal symptoms. This is called physical dependence.
If you need to stop taking this medicine, your doctor will gradually reduce the amount you take each day, if possible, before stopping the medicine completely.
Things to be careful of
Do not drive or operate machinery until you know how OxyContin tablets affect you. OxyContin tablets may cause drowsiness, dizziness, hallucinations, disorientation, blurred vision or other vision problems or may affect alertness. If you are affected, you should not drive or operate machinery. Discuss these effects with your doctor.
Be careful if you are elderly, unwell or taking other medicines. Some people may experience side effects such as drowsiness, confusion, dizziness and unsteadiness, which may increase the risk of a fall.
If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly. Standing up slowly will help your body get used to the change in position and blood pressure. If this problem continues or gets worse, talk to your doctor.
Tell your doctor if you suffer from nausea or vomiting when taking OxyContin tablets. If you vomit after your dose, your pain may come back, as you may not have absorbed your medicine. If this happens, speak to your doctor. Your doctor may prescribe some medicine to help you stop vomiting.
Tell your doctor if taking OxyContin tablets causes constipation. Your doctor can advise about your diet, the proper use of laxatives or alternative treatments, and suitable exercise you can do to help manage this.
There is potential for abuse of oxycodone and the development of addiction to oxycodone. It is important that you discuss this issue with your doctor.
All medicines may have some unwanted side effects. Sometimes they are serious but most of the time they are not. As for other medicines of this type, that is opioid analgesics, many side effects tend to reduce over time, with the exception of constipation. This means that the longer you take this medicine, the less it may cause problems for you. Your doctor has weighed the risks of this medicine against the benefits they expect it will have for you.
Do not be alarmed by this list of possible side effects. Not everybody experiences them.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking OxyContin tablets. This medicine helps most people with moderate to severe pain, but it may have unwanted side effects in a few people. Other side effects not listed here may also occur in some people.
Ask your doctor or pharmacist to answer any questions you may have.
