- Brand names include Dolophine, Methadose, Methadose Sugar-Free, and Diskets.
Classification
- Classified as an opioid analgesic.
Mechanism of Action
- Alleviates withdrawal symptoms for individuals dependent on heroin or other opioids without inducing a "high."
- Utilized in pain relief, detoxification, and maintenance programs for drug addiction.
- Dispensed exclusively through certified pharmacies.
Safety Precautions

Dosage Information
- Available strengths: 5 mg, 10 mg, 10 mg/mL, 40 mg, and various mixtures.
- For opioid non-tolerant adults, the initial parenteral dose is 2.5 mg to 10 mg IV every 8 to 12 hours.
- Maintenance doses require careful titration to avoid overdose, with consideration of the patient's opioid tolerance.
Opiate Withdrawal Treatment
- Administered under strict guidelines for detoxification and maintenance of opioid dependence per 42 CFR Section 8.12.
- The starting dose for detoxification is between 20 to 30 mg orally on day one, with possible increments if withdrawal symptoms persist.
Titration and Maintenance of Opioid Dependence
- Doses should prevent withdrawal and cravings while moderating euphoric effects.
- Targeted therapeutic range is 80 to 120 mg orally per day.
- Tapering off methadone should be gradual, with reductions of less than 10% every 10 to 14 days.
Conversion of Doses
- When switching from oral to parenteral methadone, a 2:1 conversion ratio is recommended (e.g., 10 mg oral to 5 mg parenteral).
