A. Weekly for at least 6 months, then decrease the dose to once a month: Methadone is typically administered daily, not weekly, to maintain stable blood levels and manage withdrawal symptoms effectively.
B. Daily until stabilized, then gradually reduce the dose to zero. Methadone is usually given daily to stabilize the patient. Once stabilized, the dose is gradually tapered off to prevent withdrawal symptoms and reduce dependence.
C. Monthly for 6 to 10 months, then decrease the dose to zero. Methadone treatment requires daily dosing for effective management, not monthly.
