Is it safe to take methadone while pregnant or breastfeeding?

Yes: Methadone may have an affect on fetal growth, however compared to illicit drug users, fetal outcomes are improved with Methadone users.

A bit: Methadone was thought to be safe based on studies comparing heroin using mothers to Methadone using mothers. The Methadone group and babies did better. That doesnt mean Methadone is safe, just safer than heroin. The best choice is no opioids. But if opioids are necessary Methadone up to 20 mg per day might be ok with sufficint pre and postnatal care. Baby will need detox.
