What is Methadone 40mg used for?

Methadone 40mg is itself an opioid and can be addictive. Some people can become addicted to methadone as they use it to wean themselves off of another prescription painkiller.

Methadone 40mg is a strong, synthetic (man-made) narcotic that acts on the central nervous system (brain) like other narcotics. It is used in the management of narcotic addiction and for pain control.

Dosage Methadone 40mg

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 10-40 mg given every 6-12 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 10mg given as intravenous, subcutaneous or intramuscular injection every 8-12 hours.

Methadone 40mg

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 to avoid withdrawal symptoms.
