WebMD has a list of common opiate pain relievers. Some opiates that are commonly prescribed to control pain include fentanyl, hydrocodone and oxycodone, according to WebMD.
Opiates are generally prescribed by a physician for moderate to severe chronic pain, says WebMD. These medications help alleviate pain by acting directly on the body's nervous system. Long-term use carries the potential for addiction, so patients should use these medications sparingly whenever possible and should discuss any family history of addiction with their physician. Side effects may include constipation, faintness, nausea and dry mouth. Women who may be pregnant or are nursing should avoid these medications.
