Oxycodone 5mg is used to moderate severe pain. 5 milligrams of Oxycodone changes how the brain and nervous system respond to pain. According to the patient’s pain level, the doctor has to prescribe the doses. This is the best medication, i.e., opioid drugs, like morphine, Codeine, or Methadone. You should not take more than one dose at a time if you missed one. In case you take more than one medication, it can affect your condition negatively.
