An extended-release formulation of the opioid pain reliever oxycodone hydrochloride, marketed as OxyContin, has been approved for children 11 years or older (http://1.usa.gov/1HLUNxW).
The powerful medication can be used, as it is for adults, when pain is severe enough to require daily, around-the-clock, long-term opioid treatment and other options aren’t adequate. However, unlike adults, children who take OxyContin must already have responded to and tolerated a 20-mg daily dose of opioid medication for at least 5 days.
