The extended-release form of this drug can even take three to four hours before achieving peak bloodstream concentration.

The amount a person needs to experience the pain-relieving effects varies from person to person. Typically, the doctor prescribes the lowest dose and steadily increases it while observing the progress. Those who have already used opioid medications in the past might have some tolerance to this drug, so they need a higher dose to feel the pain-relieving effects.
