Oxycodone, also available as OxyContin, is an opioid medication, sometimes called a narcotic. Oxycodone is a very powerful semi synthetic opioid. It helps relieve severe pain that requires opioid treatment where other medications didn't work or respond properly. It may cause drowsiness, sleepiness or dizziness in some people. It acts on the central nervous system to relieve pain. This medicine belongs to a group of pain medicines called opioid analgesics. The extended-release design of Oxycodone is for around-the-clock treatment of pain, and one should not use it on an as-needed basis for pain. Oxycodone dosage has many variants, such as 80 mg, 60 mg, 40 mg, 30 mg, 20 mg, 15 mg, 10 mg, and 5 mg. This medicine is often taken in the form of tablets, capsules, and oral solution formulations.
