6. Contents of the pack and other information
Targinact is a prolonged-release tablet, which means that its active substances are released over an extended period. Their action lasts for 12 hours.
These tablets are only for use in adults.
Pain relief
You have been prescribed Targinact for the treatment of severe pain, which can be adequately managed only with opioid analgesics. Naloxone hydrochloride is added to counteract constipation.
How these tablets work in pain relief
These tablets contain oxycodone hydrochloride and naloxone hydrochloride as active substances. Oxycodone hydrochloride is responsible for the pain-killing effect of Targinact, and is a potent analgesic ("painkiller") of the opioid group. The second active substance of Targinact, naloxone hydrochloride, is intended to counteract constipation. Bowel dysfunction (e.g. constipation) is a typical side effect of treatment with opioid painkillers.
Restless legs syndrome
You have been prescribed Targinact for the second line symptomatic treatment of severe to very severe restless legs syndrome in people who can't be treated with dopamine medicines. People with restless legs syndrome have unpleasant sensations in their limbs. This can start as soon as they sit or lie down and is only relieved by an irresistible urge to move the legs, sometimes the arms and other parts of the body. It makes sitting still and sleeping very difficult. Naloxone hydrochloride is added to counteract constipation.
How these tablets work in restless legs syndrome
These tablets help to relieve the unpleasant sensations and so reduces the urge to move the limbs.
The second active substance of Targinact, naloxone hydrochloride, is intended to counteract constipation. Bowel dysfunction (e.g. constipation) is a typical side effect of treatment with opioids.
Additionally for restless legs syndrome
Talk to your doctor or pharmacist before taking Targinact
Repeated use of Targinact may lead to dependence and abuse which may result in life threatening overdose. If you have concern that you may become dependent on Targinact, it is important that you consult your doctor.
Sleep-related breathing disorders
Targinact can cause sleep-related breathing disorders such as sleep apnoea (breathing pauses during sleep) and sleep related hypoxemia (low oxygen level in the blood). The symptoms can include breathing pauses during sleep, night awakening due to shortness of breath, difficulties to maintain sleep or excessive drowsiness during the day. If you or another person observe these symptoms contact your doctor. A dose reduction may be considered by your doctor.
Tell your doctor if any of the above has ever applied to you in the past. Also, please tell your doctor if you develop any of the above disorders while you are taking these tablets. The most serious result of opioid overdose is respiratory depression (slow and shallow breathing). This may also cause blood oxygen levels to fall, resulting in possible fainting, etc.
You must swallow the prolonged-release tablet whole, so as not to affect the slow release of oxycodone hydrochloride from the prolonged-release tablet. Do not break, chew or crush the tablets. Taking broken, chewed or crushed tablets may lead to the absorption of a potentially lethal dose of oxycodone hydrochloride (see section 3 "If you take more Targinact than you should").
If you experience severe diarrhoea at the start of treatment, this may be due to the effect of naloxone. It may be a sign that bowel function is returning to normal. Such diarrhoea can occur within the first 3-5 days of treatment. If diarrhoea should persist after 3-5 days, or give you cause for concern, please contact your doctor.
If you have been using another opioid, withdrawal symptoms may occur when you initially switch to Targinact treatment, e.g. restlessness, bouts of sweating and muscle pain. If you experience such symptoms, you may need to be specially monitored by your doctor.
Tolerance, dependence and addiction
This medicine contains oxycodone which is an opioid medicine. Repeated use of opioid painkillers can result in the drug being less effective (you become accustomed to it, known as tolerance). Repeated use of Targinact can also lead to dependence, abuse and addiction, which may result in life-threatening overdose. The risk of these side effects can increase with a higher dose and longer duration of use. Your prescriber should have explained how long you will be taking it for and when it is appropriate to stop, how to do this safely.
Dependence or addiction can make you feel that you are no longer in control of how much medicine you need to take or how often you need to take it. You might feel that you need to carry on taking your medicine, even when it doesn't help to relieve your pain or severe restless legs syndrome.
The risk of becoming dependent or addicted varies from person to person. You may have a greater risk of becoming dependent or addicted on Targinact if:
If you notice any of the following signs whilst taking Targinact, it could be a sign that you have become dependent or addicted.
If you notice any of these signs, speak to your doctor to discuss the best treatment pathway for you, including when it is appropriate to stop and how to stop safely (See section 3, If you stop taking Targinact).
Tell your doctor in case you have cancer associated to peritoneal metastases or beginning bowel obstruction in advanced stages of digestive and pelvic cancers.
If you need to undergo surgery, please tell your doctors that you are taking Targinact.
Similar to other opioids, oxycodone may affect the normal production of hormones in the body such as cortisol or sex hormones, particularly if you have taken high doses for long periods of time. If you experience symptoms which persist, such as feeling or being sick (including vomiting), loss of appetite, tiredness, weakness, dizziness, changes in menstrual cycle, impotence, infertility or decreased sex drive, talk to your doctor as he/she may want to monitor your hormone levels.
This medicine may increase your sensitivity to pain particularly at high doses. Tell your doctor if this happens. A reduction in your dose or a change in your medicine may be necessary.
You may notice remnants of the prolonged-release tablet in your stools. Do not be alarmed, as the active substances (oxycodone hydrochloride and naloxone hydrochloride) have already been released in the stomach and gut and absorbed into your body.
These tablets are not suitable for withdrawal treatment.
Targinact should never be abused, particularly if you have a drug addiction. If you are addicted to substances such as heroin, morphine or methadone, severe withdrawal symptoms are likely if you abuse these tablets because they contain the ingredient naloxone. Pre-existing withdrawal symptoms may be made worse.
You should never misuse these tablets by dissolving and injecting them (e.g. into a blood vessel). In particular, they contain talc, which can cause destruction of local tissue (necrosis) and changes in lung tissue (lung granuloma). Such abuse can also have other serious consequences and may even be fatal.
The use of Targinact may produce positive results in doping controls.
The use of Targinact as a doping agent may become a health hazard.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
The risk of side effects increases, if you use antidepressants (such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, venlafaxine). These medicines may interact with oxycodone and you may experience symptoms such as involuntary, rhythmic contractions of muscles, including the muscles that control movement of the eye, agitation, excessive sweating, tremor, exaggeration of reflexes, increased muscle tension, body temperature above 38°C. Contact your doctor when experiencing such symptoms.
Concomitant use of opioids, including oxycodone hydrochloride and sedative medicines such as benzodiazepines or related drugs increases the risk of drowsiness, difficulties in breathing (respiratory depression), coma and may be life-threatening. Because of this, concomitant use should only be considered when other treatment options are not possible.
However, if your doctor does prescribe Targinact together with sedative medicines the dose and duration of concomitant treatment should be limited by your doctor.
Please tell your doctor about all sedative medicines you are taking and follow your doctor's dose recommendation closely. It could be helpful to inform friends or relatives to be aware of the signs and symptoms stated above. Contact your doctor when experiencing such symptoms. Examples of these sedatives or related medicines include:
If you take these tablets at the same time as you take other medicines, the effect of these tablets or the other medicine as described below may be changed. Tell your doctor if you are taking:
No interactions are expected between Targinact and paracetamol, acetylsalicylic acid or naltrexone.
Drinking alcohol whilst taking Targinact may make you feel more sleepy or increase the risk of serious side effects such as shallow breathing with a risk of stopping breathing, and loss of consciousness. It is recommended not to drink alcohol while you're taking Targinact.
You should avoid drinking grapefruit juice while you are taking these tablets.
If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Pregnancy
Use of these tablets should be avoided to the extent possible during pregnancy. If used over prolonged periods during pregnancy, oxycodone hydrochloride may lead to withdrawal symptoms in newborn infants. If oxycodone hydrochloride is given during childbirth, respiratory depression (slow and shallow breathing) may occur in the newborn infant.
Breastfeeding
Breastfeeding should be discontinued during treatment with these tablets. Oxycodone hydrochloride passes into breast milk. It is not known whether naloxone hydrochloride also passes into breast milk. Therefore, a risk for the suckling infant cannot be excluded in particular following intake of multiple doses of Targinact.
Targinact may affect your ability to drive or operate machines. In particular, this is likely at the start of Targinact therapy, after a dose increase or after switching from a different medication. However, these side effects disappear once you are on a stable Targinact dose.
Targinact has been associated with sleepiness and episodes of suddenly falling asleep. If you experience these side effects, you must not drive or operate machinery. You should tell your doctor if this occurs.
Ask your doctor whether you may drive or operate machines.
This medicine contains lactose (milk sugar). If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking these tablets.
Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
Before starting treatment and regularly during treatment, your doctor will discuss with you what you may expect from using Targinact, when and how long you need to take it, when to contact your doctor, and when you need to stop it (see also if you stop taking Targinact).
Targinact is a prolonged-release tablet, which means that its active substances are released over an extended period. Their action lasts for 12 hours.
You must swallow the prolonged-release tablet whole, so as not to affect the slow release of oxycodone hydrochloride from the prolonged-release tablet. Do not break, chew or crush the tablets. Taking broken, chewed or crushed tablets may lead to the absorption of a potentially lethal dose of oxycodone hydrochloride (see section 3 "If you take more Targinact than you should").
Unless otherwise prescribed by your doctor, the usual dose is:
To treat pain
Adults
The usual starting dose is 10 mg oxycodone hydrochloride / 5 mg naloxone hydrochloride as prolonged release tablet(s) every 12 hours.
Your doctor will decide how much you should take every day and how to divide your total daily dosage into morning and evening doses. Your doctor will also decide on any necessary dose adjustments during treatment. Your dose will be adjusted according to your level of pain and individual sensitivity. You should be given the lowest dose needed for pain relief. If you have already been treated with opioids, Targinact treatment can be started at a higher dose.
The maximum daily dose is 160 mg oxycodone hydrochloride and 80 mg naloxone hydrochloride. If you need a higher dose, your doctor may give you additional oxycodone hydrochloride without naloxone hydrochloride. However, the maximum daily dose of oxycodone hydrochloride should not exceed 400 mg. The beneficial effect of naloxone hydrochloride on bowel activity may be affected if additional oxycodone hydrochloride is given without additional naloxone hydrochloride.
If you are switched from these tablets to another another opioid pain medication your bowel function will probably worsen.
If you experience pain between two doses of Targinact, you may need a rapid-acting painkiller. Targinact is not suitable for this. In this case, please talk to your doctor.
If you have the impression that the effect of these tablets is too strong or too weak, please talk to your doctor or pharmacist.
To treat restless legs syndrome
Adults
The usual starting dose is 5 mg oxycodone hydrochloride / 2.5 mg naloxone hydrochloride as prolonged-release tablet(s) every 12 hours.
Your doctor will decide how much Targinact you should take every day and how to divide your total daily dosage into morning and evening doses. He/she will also decide on any necessary dose adjustments during treatment. Your dose will be adjusted according to your individual sensitivity. You should be given the lowest dose needed to relieve your restless legs syndrome symptoms.
If you have the impression that the effect of Targinact is too strong or too weak, please talk to your doctor or pharmacist.
