TARGIN tablets contain two different medicines called oxycodone hydrochloride and naloxone hydrochloride dihydrate. Oxycodone belongs to a group of medicines called opioid analgesics. Naloxone is a medicine which, when taken orally, can block some of the effects of opioids in the gut, such as constipation.
TARGIN tablets are used to relieve moderate to severe persistent pain when other forms of treatment have not been effective and naloxone in TARGIN tablets will help prevent and treat opioid-induced constipation. Opioid analgesics such as oxycodone hydrochloride have been used to treat pain for many years.
Your doctor, however, may prescribe it for another purpose.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
As with all strong painkillers, your body may become used to you taking TARGIN tablets. 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.

How much to take
Your doctor will tell you exactly how much to take.
Follow the instructions given to you by your doctor or pharmacist exactly.
How to take it
Swallow TARGIN tablets whole with a full glass of water.
Do not chew, crush, break or dissolve the tablets.
TARGIN tablets are only designed to work properly if swallowed whole. The tablets may release all their contents at once if chewed, crushed, broken or dissolved which can be dangerous and cause serious problems, such as an overdose or even death.
If you have trouble swallowing your tablets whole, talk to your doctor.
You must only take TARGIN tablets by mouth.
Taking this medicine in a manner other than that prescribed by your doctor can be harmful to your health.
When to take it
Take TARGIN tablets every 12 hours.
Taking them at the same time each day will have the best effect and will mean that the onset of pain is prevented. If however, you begin to experience pain (‘breakthrough pain’) and you are taking your TARGIN tablets as prescribed, contact your doctor as your dosage may need to be reviewed.
You may take this medicine with or without food.
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 pain or diarrhoea
- fast heart rate
- sneezing or runny nose
- chills, tremors, shivering or fever
- trouble with sleeping
- increased sweating and yawning
- nervousness or restlessness.
If you forget to take it
If you forget to take your tablets, take your next dose as soon as you remember, unless it is almost time for your next dose, then go on as before.
Do not take a double dose to make up for the dose that you missed. This will increase the chance of you getting unwanted side effects.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering when to take your tablets, ask your pharmacist for some 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, New Zealand: telephone 0800 POISON or 0800 764 766) for advice, or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too many TARGIN tablets.
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 taken the tablets that were prescribed for you.
If someone takes an overdose they may experience difficulties in breathing, become drowsy and tired, have constricted pupils, become confused, 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 report any other medicines or alcohol which have been taken.

Tolerance to oxycodone may develop which means that the effect of the medicine may decrease. If this happens, speak to your doctor. Keep enough TARGIN tablets with you to last over weekends and holidays.
Things you must not do
Do not drink alcohol while you are taking TARGIN tablets.
Alcohol use could increase serious side effects of oxycodone, such as sleepiness, drowsiness, and slow or shallow breathing.
Do not take TARGIN 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 or change the dosage without checking with your doctor.
Over time your body may become used to you taking oxycodone so 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 TARGIN tablets affect you.
TARGIN tablets may cause drowsiness, dizziness, hallucinations, disorientation, blurred vision or other vision problems or may affect alertness. Discuss these aspects and any impact on your driving or operating machinery 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 TARGIN tablets.
If you vomit after your dose, your pain may come back, as you will not have absorbed your medicine. If this happens, speak to your doctor. Your doctor may prescribe some medicine to help you stop vomiting.
Do not be alarmed if you see remnants of the tablet in your stool.
The active substances have already been released in the stomach and gut, and absorbed into your body.
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.
Be aware that TARGIN tablets may produce a positive result in sports agency drug testing procedures.
Keep your tablets in the blister pack until it is time to use them. If you take the tablets out of the blister pack they may not keep as well.
Keep your tablets in a cool, dry place where the temperature stays below 25°C.
Do not store it or any other medicine in the bathroom, near a sink or on a window sill.
Do not leave it in the car. Heat and damp can destroy some medicines.
Keep it where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
If your doctor tells you to stop taking the tablets or the tablets have passed their expiry date, return any unused medicine to your pharmacist.
