What is the dosage for methadone liquid-oral?

  • The initial dose of oral methadone in patients who require continuous pain control throughout the day can range from 2.5 to 10 mg given every 8 to 12 hours.
  • Those who are seriously ill may need to be started at an oral dose of 10 to 40 mg given every 6 to 12 hours.
  • The initial total daily dose for detoxification usually is higher, and this can range from 20 to 120 mg daily.
  • The usual dose for methadone solution for injection when treating moderate to severe pain in patients who require continuous pain control is 2.5 to 10 mg given as intravenous (I.V.), subcutaneous (SubQ) or intramuscular (I.M.) injection every 8-12 hours.
  • The conversion ratio from oral methadone to methadone given as an injection (I.V., SubQ) or I.M.) is 2:1. The total daily amount of methadone that a person is prescribed is not fixed, and it will depend on many factors including the severity of the pain, prior use of methadone, medications that are being taken concomitantly, the response to treatment and other factors that may be specific to a person.
  • Therefore, each person has to be monitored carefully while receiving methadone. When stopping therapy, the dose of methadone should be gradually reduced in order to avoid withdrawal symptoms.

Which drugs or supplements interact with methadone liquid-oral?

Is methadone liquid-oral safe to take if I'm pregnant or breastfeeding?

Safety during pregnancy has not been established. Methadone has been shown to cross the placenta, and it is found in cord blood, amniotic fluid and in the newborn urine. Children born to mothers who were taking methadone for a prolonged period may exhibit respiratory depression or withdrawal symptoms.

The benefit to the mother of taking methadone while breast feeding should be weighed against the risks to the infant.
