Talk to your doctor if any of the above have affected you in the past. Also, talk to a doctor if you experience any of the above while taking Oxycodone / Naloxone GL

Oxycodone / Naloxone GL is not recommended for the treatment of patients with advanced cancer of the gastrointestinal tract or pelvis where intestinal obstruction may be a problem.

If you experience severe diarrhea at the beginning of treatment (within the first 3 to 5 days), this may be due to the effect of naloxone. It may be a sign that your bowel movements are returning to normal. Contact a doctor if diarrhea persists after 3 to 5 days, or is worrying.

If you have used high doses of another opioid, you may initially experience withdrawal symptoms (such as restlessness, sweating, and muscle pain) when switching to Oxycodone / Naloxone GL. If you experience withdrawal symptoms, you may need special medical attention.

Tell your doctor that you are taking Oxycodone / Naloxone GL if you need surgery.

If you have been taking Oxycodone / Naloxone GL for a long time, you may become tolerant. This means that you may need a higher dose to achieve the desired effect. Prolonged use of this drug can also lead to physical dependence. Medicines containing oxycodone should be avoided in patients with current or past alcohol, drug, or drug abuse. Withdrawal symptoms can occur if treatment is stopped too suddenly. If you no longer need treatment, gradually reduce your daily dose in consultation with your doctor.

There is a risk of developing psychological dependence on oxycodone.

Residues of prolonged-release tablets may be present in the feces. This is nothing to worry about, as the active substances have already been released in the stomach and intestines and absorbed into the body.

Improper use of Oxycodone / Naloxone GL

Oxycodone / Naloxone GL should never be abused, especially if you have a drug addiction. If you are addicted to drugs such as heroin, morphine, or methadone , you are likely to suffer from severe withdrawal symptoms if you abuse Oxycodone / Naloxone GL, as it contains the active substance naloxone. Pre-existing withdrawal symptoms may worsen.

Oxycodone / Naloxone GL prolonged-release tablets should never be abused by dissolving and injecting (eg into a blood vessel) or inhaling. The tablets contain talc that can destroy local tissue ( necrosis ) and cause changes in the lung tissue (lung granuloma). Improper use can also have other serious consequences that can be life-threatening.

The prolonged-release tablets must be swallowed whole so as not to affect the slow release of oxycodone from the tablets. The tablets must not be split, broken, chewed, or crushed. If the tablets are split, broken, chewed, or crushed, this may cause the body to take up a potentially life-threatening dose of oxycodone (see section 3 “If you take more Oxycodone / Naloxone GL”).

Children and young people

This medicine should not be given to children or adolescents under 18 years of age when safety and efficacy have not been established.

Other medicines and Oxycodone / Naloxone GL

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 take Oxycodone / Naloxone GL at the same time as medicines that affect brain function. For example, you may feel very tired and breathing difficulties (slow and shallow breathing) may worsen.

Examples of drugs that affect brain function:

  • other strong painkillers ( opioids )
  • hypnotics and sedatives ( sedatives, hypnotics )
  • antidepressant drugs (such as paroxetine or fluoxetine )
  • medicines used to treat allergies, motion sickness, or nausea ( antihistamines or antiemetics)
  • other drugs that affect the nervous system (phenothiazines, neuroleptics )

The risk of side effects is increased if you take antidepressant drugs (for example, citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline , venlafaxine ). These drugs can affect or be affected by oxycodone, and you may experience symptoms such as involuntary, rhythmic muscle contractions, including in the muscles that control eye movements, sudden movements, heavy sweating, tremors, excessive reflexive movements, increased muscle tension, body temperature above 38 ° C. Contact your doctor if you experience these symptoms.

Concomitant use of Oxycodone / Naloxone GL and sedatives or medicines for insomnia such as benzodiazepines or similar medicines increases the risk of drowsiness, difficulty breathing ( respiratory depression ), coma and may be life-threatening. Due to this, concomitant use should only be considered when other treatment options are not possible. If your doctor prescribes Oxycodone / Naloxone GL at the same time as sedatives, dose one and the treatment time should be limited by your doctor.

Tell your doctor if you are taking any sedatives and carefully follow your doctor’s dose recommendations. It may be helpful to inform friends or relatives about paying attention to the signs and symptoms described above. Contact a doctor if you experience any of these symptoms.

  • drugs that reduce the coagulation capacity of the blood (coumarin derivatives), the coagulation time may be faster or slower
  • Macrolide type antibiotics are (eg clarithromycin, erythromycin, telithromycin )
  • antifungal drugs of the type azoles (eg ketoconazole , voriconazole, itraconazole, posaconazole)
  • ritonavir or other protease inhibitors (used to treat HIV, eg indinavir, nelfinavir, saquinavir)
  • cimetidine (used to treat stomach ulcers, stomach upset, or heartburn).
  • rifampicin (used to treat tuberculosis )
  • carbamazepine (used to treat seizures and certain pain conditions)
  • phenytoin (used to treat seizures)
  • St. John’s wort (also known as Hypericum perforatum).
  • quinidine (used to treat irregular heartbeat).
