1. What Oxyact is and what it is used for

Oxyact is a strong painkiller from the group of opioids.

Oxyact is indicated in adults and adolescents (from 12 years and older) for the treatment of severe pain, which can be adequately managed only with opioid analgesics.

2. What you need to know before you take Oxyact
Do not take Oxyact
  • if you are allergic to oxycodone hydrochloride, peanut or soya or any of the other ingredients of this medicine (listed in section 6).
  • if you have breathing problems, such as breathing more slowly or more weakly than expected (respiratory depression).
  • if you have too much carbon dioxide in your blood.
  • if you suffer from a severe chronic lung disease associated with narrowing of the airways (COPD = chronic obstructive pulmonary disease).
  • if you have a certain heart condition known as cor pulmonale.
  • if you have asthma.
  • if you have a type of bowel obstruction called paralytic ileus.
  • if you have acute severe stomach pain or suffer from a delayed stomach emptying.

Warnings and precautions

Talk to your doctor or pharmacist before using Oxyact

  • if you are elderly or debilitated (weak).
  • if your lung, liver or kidney function is severely impaired.
  • if you have a certain disorder of the thyroid gland (myxoedema) or if your thyroid gland does not produce enough hormone (underactive thyroid).
  • if you have poor adrenal gland function (your adrenal gland is not working properly) for example Addison’s disease.
  • if your prostate is abnormally enlarged.
  • if you have a mental illness caused by alcohol or intoxication with other substances,
  • if you are undergoing alcohol withdrawal treatment
  • if you are, or were previously, dependent on strong pain killers (opioids).
  • if you have problems with your gall bladder.
  • if you have an inflammation of the pancreas which can cause severe pain in the abdomen or back.
  • if you have difficulty or pain passing urine.
  • if your doctor suspects you have intestinal paralysis (a condition where the bowel has stopped working)
  • have inflammatory bowel disease.
  • if you have a head injury with severe headache or discomfort – signs your brain pressure is increased.
  • if you have low blood pressure or feel dizzy standing up.
  • have low blood volume (hypovolaemia).
  • if you suffer from epilepsy or are prone to fits.
  • if you are also taking a type of medicine known as take so called MAO inhibitors (generally used to for the treatment of depression or Parkinson’s disease) or if you have been taking them within the last 2 weeks
  • if you suffer from constipation

Sleep-related breathing disorders

Oxyact can cause sleep-related breathing disorders such as sleep apnea (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.

The most significant threat of opioid overdose is a flattening and slowing of breathing (respiratory depression). This is most likely to occur in the elderly and debilitated patient and can also cause the oxygen level in the blood to decrease. This could lead to e.g. faint.

Tolerance, dependence and addiction

This medicine contains oxycodone, which is an opioid. It can cause dependence and/or addiction.

When Oxyact is used for long-time treatment, tolerance to the medicine may occur. This means, that you may need a higher dose to achieve the desired pain relief. Do not change the dosage without consulting your doctor.

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 Oxyact may 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.

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.

The risk of becoming dependent or addicted varies from person to person. You may have a greater risk of becoming dependent or addicted on Oxyact if:

  • you or anyone in your family have ever abused or been dependent on alcohol, prescription medicines or illegal drugs (“addiction”).
  • you are a smoker.
  • you have ever had problems with your mood (depression, anxiety or a personality disorder) or have been treated by a psychiatrist for other mental illnesses.

If you notice any of the following signs whilst taking Oxyact, it could be a sign that you have become dependent or addicted.

  • You need to take the medicine for longer than advised by your doctor
  • You need to take more than the recommended dose
  • You are using the medicine for reasons other than prescribed, for instance, ‘to stay calm’ or ‘help you sleep’
  • You have made repeated, unsuccessful attempts to quit or control the use of the medicine
  • When you stop taking the medicine you feel unwell, and you feel better once taking the medicine again (‘withdrawal effects’)

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 Oxyact).

Oxyact has a dependence potential. If the treatment is stopped too suddenly, withdrawal symptoms such as yawning, dilted pupils, tearing, runny nose, tremors, sweating, anxiety, restlessness, seizures, insomnia or muscle pain may occur. If you no longer need treatment, your doctor will gradually reduce your daily dose.

Your doctor will weigh the possible risks against the expected and needs to be evaluated in relation to the benefit. Ask your doctor if you have any questions about this.

The active ingredient oxycodone hydrochloride, like other highly effective opioids (strong pain killers), has potential for abuse. The development of psychological addiction is possible. Oxyact should only be used with particular caution if there has been or has been a history of alcohol, drug or drug abuse.

Particularly in high doses, increased sensitivity to pain (hyperalgesia) can occur, which does not respond to a further increase in the dose of Oxyact. Your doctor will then decide whether to reduce the dose or switch to this strong pain reliever (opioid).

Oxyact is for ingestion only (swallowing as a whole film-coated tablet). The film-coated tablets must not be dissolved and injected, as this can have serious, possibly fatal consequences.

If you need to have an operation, please tell your doctor that you are taking Oxyact.

Contact your doctor if you experience severe upper abdominal pain possibly radiating to the back, nausea, vomiting or fever as this could be symptoms associated with inflammation of the pancreas (pancreatitis) and the biliary tract system.

Similar to other opioids, oxycodone can affect the body's normal production of hormones (such as cortisol and sex hormones). This happens especially after you have received large doses for long periods of time.

Children

The safety and efficacy of Oxyact in children under 12 years of age has not been established. Therefore, use of Oxyact is not recommended in this age group.

Anti-Doping Warning

Athletes must be aware that this medicine may cause a positive reaction to “anti-doping” tests. Use of Oxyact as a doping agent may become a health hazard.

Other medicines and Oxyact

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Concomitant use of Oxyact 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 Oxyact 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.

Medicines that affect the way the brain works include:

  • sleeping pills or sedatives (e.g. hypnotics or sedatives, including benzodiazepines)
  • medicines for depression (e.g. paroxetine or amitriptyline), including those belonging to a group of MAOIs (such as tranylcypromine, phenelzine, isocarboxazid, moclobemide or linezolid),
  • medicines for allergies, motion sickness or vomiting (antihistamines, antiemetics),
  • medicines for psychological or mental disorders (such as psychotropic drugs, phenothiazines or neuroleptics),
  • Medicines used to treat epilepsy, pain and anxiety such as e.g. gabapentin and pregabalin.

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.

Please tell your doctor or pharmacist if you are taking any of the medicines from the following list:

  • muscle relaxants used to treat muscle spasms (such as tizanidine)
  • medicines used to treat Parkinson's disease,
  • other strong pain relievers (opioids),
  • cimetidine (a medicine for stomach ulcers, indigestion or heartburn),
  • medicines for fungal infections (such as ketoconazole, voriconazole, itraconazole or posaconazole),
  • medicines for bacterial infections (such as clarithromycin, erythromycin or telithromycin),
  • medicines from the group of protease inhibitors to treat HIV infection (e.g. boceprevir, ritonavir, indinavir, nelfinavir or saquinavir),
  • rifampicin for tuberculosis,
  • carbamazepine (a medicine for epilepsy or seizures and for certain types of pain),
  • phenytoin (a medicine for epilepsy or seizures),
  • the medicinal plant St. John's wort (also known as Hypericum perforatum),
  • quinidine (a medicine for irregular heartbeat),
  • certain medicines to prevent blood clotting or to thin the blood (such as phenprocoumon).

Oxyact with drink and alcohol

Oxyact should not be taken with alcohol. Alcohol use could increase serious side-effects of oxycodone, such as sleepiness and drowsiness and slow and shallow breathing.

Oxyact should be avoided in patients with a history of or present alcohol and drug abuse.

Grapefruit juice may increase the levels of oxycodone in your blood. Check with your doctor if you drink grapefruit juice regularly.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Pregnancy

The use of Oxyact should be avoided to the extent possible during pregnancy.

Prolonged use of oxycodone during pregnancy can cause withdrawal symptoms in newborns. If oxycodone is given during childbirth, the baby may have breathing problems (respiratory depression).

Breast-feeding

Breast-feeding should be discontinued during treatment with Oxyact. Oxycodone hydrochloride passes into breast milk and may cause sedation and shallow and slow breathing (respiratory depression) in the breast-fed child. Therefore, a risk for the suckling infant cannot be excluded in particular following intake of multiple doses of Oxyact

The medicine can affect your ability to drive as it may make you sleepy or dizzy.

  • Do not drive while taking this medicine until you know how it affects you.
  • It is an offence to drive if this medicine affects your ability to drive.
  • However, you would not be committing an offence if:
    • The medicine has been prescribed to treat a medical or dental problem and
    • You have taken it according to the instructions given by the prescriber or in the information provided with the medicine and
    • It was not affecting your ability to drive safely

Dosage

For doses not realisable/practicable with this strength, other strengths of this medicinal product are available.

Your doctor will adjust your dose according to pain intensity and to your individual susceptibility.

Do not change the dosage without consulting your doctor.

You should be given the lowest effective dose sufficient to relieve your pain.

If you have previously been treated with opioids, your doctor may start your therapy with a higher dose.

It may be necessary to increase the dose gradually if the pain relief is insufficient or if the pain becomes worse.

Please talk to your doctor, if you think that the effect of Oxyact is too weak or too strong.

If not prescribed otherwise by your doctor, the recommended dose is
  • for adults and adolescents (from 12 years and older):
    The usual starting dose is 5 mg every 6 hours. The dosing interval of Oxyact may be reduced to 4 hours if required. Oxyact should not be taken more than 6 times a day.
    However, your doctor will prescribe the dose required to treat your pain. If you find that you are still in pain whilst taking these tablets, discuss this with your doctor.
  • for the elderly (65 years and older):
    Elderly patients with normal liver and/or kidney function may take the same doses as given for adults above.
  • for patients with kidney and/or liver disorders:
    If you have liver or kidney problems and you have not yet received opioids, you should start with half the recommended adult dose.
  • for other risk patients:
    If you are light or if your body metabolizes medicines more slowly, the starting dose should be half the recommended adult dose.
  • for children (below 12 years):
    Safety and efficacy of Oxyact have not been tested sufficiently in children under 12 years of age. Therefore, treatment with Oxyact is not recommended in children under 12 years of age.

For patients who have been treated with other strong pain killers (opioids) before, the doctor may prescribe a higher starting dose.

Your doctor will decide how much you should take every day after that, and how to divide your total daily dose into morning and evening doses. Your doctor will also advise you on any dose adjustments that may become necessary during treatment.

If you experience pain between doses of Oxyact, you may require higher doses of Oxyact Please talk to your doctor if you have this problem.

If you require long-term treatment of severe pain, you will be switched to oxycodone hydrochloride prolonged-release tablets.

Method of administraion

Oral use.

Take this medicine with a sufficient amount of liquid (e.g. ½ glass of water) every 4 to 6 hours as scheduled by your doctor. You can take this medicine with or without food.

Duration of application

Your doctor will tell you how long to take Oxyact.

Do not stop your Oxycodone hydrochloride G.L treatment without talking to your doctor (see “If you stop taking Oxyact”).

If you take Oxyact for a long time, you should monitor your therapy and discuss it with your doctor regularly. This is necessary in order to achieve the best possible pain therapy, i.e. to enable timely treatment of occurring side effects as well as a decision on dose adjustment and continuation of treatment.
