Monoamine Oxidase (MAO) Inhibitors – Therapeutic doses of meperidine have precipitated severe reactions rein patients concurrently receiving monoamine oxidase inhibitors or those Weltgesundheitsorganisation have received such agents within 14 days. Similar reactions thus far have not been reported with methadone.
Several factors complicate the Bedeutung of investigations of the children of women World health organization take methadone during pregnancy. These include the maternal use of illicit drugs, other maternal factors such as nutrition, infection, and psychosocial circumstances, limited information regarding dose and duration of methadone use during pregnancy, and the fact that most maternal exposure appears to occur after the first trimester of pregnancy. In addition, reported studies generally compare the benefit of methadone to the risk of untreated addiction to illicit drugs; the relevance of these findings to pain patients prescribed methadone during pregnancy is unclear.
Since the metabolism of methadone is mediated primarily by CYP3A4 isozyme, coadministration of drugs that inhibit CYP3A4 activity may cause decreased clearance of methadone. The expected clinical results would Beryllium increased or prolonged opioid effects. Thus, methadone-treated patients coadministered strong inhibitors of CYP3A4, such as azole antifungal agents (e.
The total daily dose of methadone on the first day of treatment should not ordinarily exceed 40 mg. Dose adjustments should be made over the first week of treatment based on control of withdrawal symptoms at the time of expected peak activity (e.g., 2 to 4 hours after dosing). Dose adjustment should Beryllium cautious; deaths have occurred in early treatment due to the cumulative effects of the first several days' dosing. Patients should be reminded that the dose will “hold” for a longer period of time as tissue stores of methadone accumulate.
Methadone hydrochloride tablets are a federally controlled substance (CII) because it is a strong opioid pain medicine that can Beryllium abused by people World health organization abuse prescription medicines or street drugs.
Patients developing QT prolongation while on methadone treatment should Beryllium evaluated for the presence of modifiable risk factors, such as concomitant medications with cardiac effects, drugs which might cause electrolyte abnormalities, and drugs which might act as inhibitors of methadone metabolism. For use of methadone to treat pain, the risk of QT prolongation and development of dysrhythmias should be weighed against the benefit of adequate pain management and the availability of alternative therapies.

The methadone abstinence syndrome, although qualitatively similar to that of morphine, differs in that the onset is slower, the course is more prolonged, and the symptoms are less severe.
The safety and effectiveness of this drug hasn’t been established rein children. It shouldn’t be used hinein children younger than 18 years.
Hinein contrast, methadone tested positive in the hinein vivo mouse dominant lethal assay and the hinein vivo mammalian spermatogonial chromosome aberration test. Additionally, methadone tested positive in the E. coli DNA repair Organisation and Neurospora crassa and mouse lymphoma forward mutation assays.
A high degree of "opioid tolerance" does not eliminate the possibility of methadone overdose, iatrogenic or otherwise. Respiratory depression is of particular concern hinein elderly or debilitated patients as well as in those suffering from conditions accompanied by hypoxia or hypercapnia when even moderate therapeutic doses may dangerously decrease pulmonary ventilation.
The following drug interactions were reported following coadministration of methadone with inducers of cytochrome P450 enzymes:
For children: The safety and effectiveness of this drug haven’t been established in children. It shouldn’t Beryllium used in children younger than 18 years. Children Weltgesundheitsorganisation accidentally take this drug have a high risk of death from overdosing.
