There are conflicting reports on whether SIDS occurs with an increased incidence rein infants born to women treated with methadone during pregnancy.
Optimal methadone initiation and dose titration strategies for the treatment of pain have not been determined.

One published study hinein pregnant hamsters indicated that a single subcutaneous dose of methadone ranging from 31 to 185 Magnesium/kg (the 31 Magnesium/kg dose is approximately 2 times a human daily oral dose of 120 Magnesium/day on a Magnesium/m2 Stützpunkt) on day 8 of gestation resulted rein a decrease rein the number of fetuses per litter and an increase in the percentage of fetuses exhibiting congenital malformations described as exencephaly, cranioschisis, and “various other lesions”.
Based on an average milk consumption of 150 mL/kg/day, an infant would consume approximately Methadontabletten online zu verkaufen 17.4 mcg/kg/day which is approximately 2 to 3% of the oral maternal dose. Methadone has been detected rein very low plasma concentrations rein some infants whose mothers were taking methadone.

Some data also indicate that methadone acts as an antagonist at the Stickstoffgas-methyl-D-aspartate (NMDA) receptor. The contribution of NMDA receptor antagonism to methadone's efficacy is unknown. Other NMDA receptor antagonists have been shown to produce neurotoxic effects hinein animals.
Methadone hydrochloride tablets can cause life-threatening breathing problems which can lead to death. These problems are more likely to happen when methadone hydrochloride tablets are first started or rein someone Weltgesundheitsorganisation is not already taking other narcotic (opioid) pain medicines.
Laboratory studies, both hinein vivo and in vitro, have demonstrated that methadone inhibits cardiac potassium channels and prolongs the QT interval. Cases of QT interval prolongation and serious arrhythmia (torsades de pointes) have been observed during treatment with methadone. These cases appear to Beryllium more commonly associated with, but not limited to, higher dose treatment (> 200 mg/day). Most cases involve patients being treated for pain with large, multiple daily doses of methadone, although cases have been reported rein patients receiving doses commonly used for maintenance treatment of opioid addiction.
