Dependence and tolerance

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.

Repeated use of Oxyact may lead to dependence and abuse which may result in life-threatening overdose. If you have concern that you may become dependent on Oxyact, it is important that you consult your doctor.

Oxyact has a dependence potential. If the treatment is stopped too suddenly, withdrawal symptoms 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.

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 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.

Other medicines and Oxyact

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

The risk of side effects is increased if you take Oxyact at the same time as medicines which affect the way the brain works. For example, you may feel very sleepy, or breathing problems may get worse.

Medicines that affect the way the brain works include:

  • other strong pain killers (opioids),
  • sleeping pills and tranquillisers,
  • antidepressants,
  • medicines used to treat allergies, travel sickness or nausea (antihistamines or antiemetics),
  • other medicines which act on the nervous system (phenothiazines, neuroleptics),
  • medicines used to treat Parkinson’s disease (so-called MAO inhibitors, see also section “Warnings and precautions”).

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 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.

Further interactions may occur with

  • cimetidine (used to manage excess of gastric acid). It may prolong the duration of effects of Oxyact in your body.
  • medicines against blood clotting (e.g. warfarin). Oxyact may influence their effects.
  • certain antibiotics, antifungal medicines and medicines containing St. John’s Wort.

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.
