Methadone is used to treat moderate to severe pain when around-the-clock pain relief is needed for a long period of time. This medicine should not be used to treat pain that you only have once in a while or "as needed". Methadone is also used together with medical supervision and counseling to treat opioid addiction (eg, heroin or other morphine-like pill).
Methadone is an opioid (narcotic) analgesic (pain medicine). It acts on the nervous system to relieve pain. This medicine is available only with your doctor's prescription.
Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. This is especially important for elderly patients, who may be more sensitive to the effects of pain medicines.
This medicine comes with a Medication Guide. Read and follow the instructions carefully. Ask your doctor if you have any questions.
Swallow the tablet whole. Do not crush, break, chew, or dissolve it.
