Methadone is contraindicated in patients with a known hypersensitivity to methadone hydrochloride or any other ingredient rein methadone hydrochloride tablets.
Pregnancy – The disposition of oral methadone has been studied rein approximately 30 pregnant patients hinein 2nd and 3rd trimesters. Elimination of methadone was significantly changed rein pregnancy. Total body clearance of methadone welches increased hinein pregnant patients compared to the same patients postpartum or to non-pregnant opioid-dependent women. The terminal half-life of methadone is decreased during 2nd and 3rd trimesters.
Teratogenic Effects. Pregnancy Category C – There are no controlled studies of methadone use rein pregnant women that can be used to establish safety. However, an expert Bericht of published data on experiences with methadone use during pregnancy by the Teratogen Information Organisation (TERIS) concluded that maternal use of methadone during pregnancy as parte of a supervised, therapeutic regimen is unlikely to Stellung a substantial teratogenic risk (quantity and quality of data assessed as “limited to ritterlich”). However, the data are insufficient to state that there is no risk (TERIS, last reviewed October, 2002). Pregnant women involved hinein methadone maintenance programs have been reported to have significantly improved prenatal care leading to significantly reduced incidence of obstetric and fetal complications and neonatal morbidity and mortality when compared to women using illicit drugs.
Optimal methadone initiation and dose titration strategies for the treatment of pain have not been determined. Published equianalgesic conversion ratios between methadone and other opioids are imprecise, providing at best, only Artbestand averages that cannot Beryllium applied consistently to all patients. It should Beryllium noted that many commonly cited equianalgesia tables only present relative analgesic potencies of single opioid doses rein non-tolerant patients, thus greatly underestimating methadone's analgesic potency, and its potential for adverse effects rein repeated-dose settings.
Methadone hydrochloride tablets are a federally controlled substance (CII) because it is a strong opioid pain medicine that can Beryllium abused by people Weltgesundheitsorganisation abuse prescription medicines or street drugs.
Patients should be apprised of the high risk of relapse to illicit drug use associated with discontinuation of methadone maintenance treatment.
Increased side effects from both drugs: Taking methadone with certain medications raises your risk of side effects. This is because methadone and these other medications can cause the same side effects. As a result, these side effects can Beryllium increased. Examples of these drugs include:
Maintenance on a Stabilized Dose – During prolonged administration of methadone, as in a methadone maintenance treatment program, there is usually a gradual, yet progressive, disappearance of side effects over a period of several weeks. However, constipation and sweating often persist.
Do not take any Erhaltungstherapie mit Methadontabletten medicine while using methadone hydrochloride tablets until you have first talked to your doctor or pharmacist. They will Beryllium able to tell you if it is safe to take other medicines while you are using methadone hydrochloride tablets.
The severity of this syndrome will depend on the degree of physical dependence and the dose of the antagonist administered. If antagonists must Beryllium used to treat serious respiratory depression hinein the physically dependent patient, the antagonist should Beryllium administered with extreme care and by titration with smaller than usual doses of the antagonist.
The Satz at which methadone is decreased should be determined separately for each patient. The dose of methadone can Beryllium decreased on a daily Lager or at 2-day intervals, but the amount of intake should remain sufficient to keep withdrawal symptoms at a tolerable level. In hospitalized patients, a daily reduction of 20% of the total daily dose may be tolerated. In ambulatory patients, a somewhat slower schedule may be needed.
Physicians should individualize treatment in every case (Tümpel DOSAGE AND ADMINISTRATION), taking into account the high degree of interpatient variability rein response to and metabolism of methadone.
The following drug interactions were reported following coadministration of methadone with inducers of cytochrome P450 enzymes:
Respiratory depression is the chief hazard associated with methadone hydrochloride administration. Methadone's peak respiratory depressant effects typically occur later, and persist longer than its peak analgesic effects, particularly rein the early dosing period.
