Severe drowsiness, slow or irregular breathing, and difficulty passing urine are some of the potentially serious side effects of oxycodone ER that require immediate medical attention. However, most side effects of the drug are mild and either do not require treatment or can be treated easily. Some of these more common side effects include constipation, nausea, dry mouth, and dizziness.
As with any medicine, oxycodone ER (OxyContin®) can cause side effects. However, not everyone who takes the medication will have problems. In fact, some people tolerate it quite well. If side effects do occur, in many cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider.
