Oxycodone is available as slow-release tablets, regular pills, capsules, oral liquid, and fast-acting injections. Extended-release pills are used 24/7 to treat severe and chronic pain that needs longer-term care, whereas these faster-acting variants are used as needed for acute (short-term) pain. As-needed pain relief should not be achieved with extended-release medications. Additionally, Oxycodone40 mg is offered as an immediate-release form.
