For the treatment of moderate to severe pain in patients with cancer and post-operative pain. For the treatment of severe pain requiring the use of a strong opioid.
4.2 Posology and method of administration
Adults over 18 years:
OxyContin tablets should be taken at 12-hourly intervals. The dosage is dependent on the severity of the pain, and the patient’s previous history of analgesic requirements.
Prior to starting treatment with opioids, a discussion should be held with patients to put in place a strategy for ending treatment with oxycodone in order to minimize the risk of addiction and drug withdrawal syndrome (see section 4.4).
OxyContin is not intended for use as a prn analgesic.
Increasing severity of pain will require an increased dosage of OxyContin tablets, using the 5 mg, 10 mg, 20 mg, 40 mg or 80 mg tablet strengths, either alone or in combination, to achieve pain relief. The correct dosage for any individual patient is that which controls the pain and is well tolerated for a full 12 hours. Patients should be titrated to pain relief unless unmanageable adverse drug reactions prevent this. If higher doses are necessary, increases should be made in 25% – 50% increments. The need to escape medication more than twice a day indicates that the dosage of OxyContin tablets should be increased.
The usual starting dose for opioid naïve patients or patients presenting with severe pain uncontrolled by weaker opioids is 10 mg, 12-hourly. Some patients may benefit from a starting dose of 5 mg to minimize the incidence of side effects. The dose should then be carefully titrated, as frequently as once a day if necessary, to achieve pain relief. For the majority of patients, the maximum dose is 200 mg 12-hourly. However, a few patients may require higher doses. Doses in excess of 1000 mg daily have been recorded.
