Objective:
To examine the longitudinal use of methadone in a pain clinic.
Design:
Follow-up study of 40 patients initially treated with methadone and re-evaluated 2 years later, comparing those maintained on methadone with those who were switched to other opioids.
Setting:
Pain clinic at a university hospital.
Results:
The 14 patients (35%) who stayed on methadone for the duration of the study, had higher employment rates (P <.05) and higher functional ratings (P <.02) than those on other opioids. Side effects were the most common reason (33.4%) for discontinuation of methadone. Dose escalation occurred in 11 of 14 patients (78.6%).
Conclusions:
Chronic pain patients may be safely and effectively treated with methadone. Those not responding or tolerating methadone may be benefited by treatment with other opioids.
