Oxynorm capsules contain oxycodone hydrochloride. Oxycodone belongs to a group of medicines called opioid analgesics. OxyNorm capsules are used to relieve moderate to severe pain. 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 Oxynorm capsules. Taking it may result in physical dependence. Physical dependence means that you may experience withdrawal symptoms if you stop taking oxycodone 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 OxyNorm capsules may result in a decrease in sex hormone levels which may affect sperm production in men and the menstrual cycle in females. Talk to your doctor if you have any concerns.

- chills, tremors, shivering or fever

If you forget to take it
If you forget to take your capsules, 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 take too much (overdose)
Immediately telephone your doctor, or the Poisons Information Centre (Australia: telephone 13 11 26, New Zealand: telephone 0800 POISON or 0800 764 766) for advice, or go to Accident and Emergency at your nearest hospital, if you think you or anyone else may have taken too many OxyNorm capsules.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
Keep telephone numbers for these places handy.
You should also follow the above steps if someone other than you has accidently taken the tablets that were prescribed for you.
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 possibly may even become unconscious or die.
When seeking medical attention, take this leaflet and any remaining capsules 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 OxyNorm capsules exactly as your doctor has prescribed.
Before you start on a new medicine, remind your doctor and pharmacist that you are taking Oxycodone capsules.
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. Always discuss any problems or difficulties you have while you are taking OxyNorm capsules.
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 OxyNorm capsules with you to last over weekends and holidays.
Things you must not do
Do not drink alcohol while you are taking OxyNorm capsules. Drinking alcohol whilst taking OxyNorm capsules 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 OxyNorm capsules 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 have 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 OxyNorm capsules affect you. OxyNorm capsules 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 OxyNorm capsules. 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 OxyNorm capsules causes constipation. Your doctor can advise about your diet, the proper use of laxatives and suitable exercise you can do to help manage this.
There is potential for abuse of oxycodone and the development of dependence. It is important that you discuss this issue with your doctor.
