Babies can experience withdrawal symptoms if their mothers were taking Subutex during pregnancy. Subutex, which contains buprenorphine, is a medication used to treat opioid addiction. If a woman takes Subutex during pregnancy, the medication can pass through the placenta and into the baby’s system. As a result, the baby may develop a dependence on the drug and experience withdrawal symptoms after birth. This condition is known as neonatal abstinence syndrome (NAS). The symptoms of NAS can include tremors, irritability, feeding difficulties, seizures, and other symptoms. It is important for women who are taking Subutex or other medications for opioid addiction to discuss the risks and benefits of the medication with their healthcare provider and to seek appropriate medical care during pregnancy.
