Zydol Use In Pregnancy & Lactation

Pregnancy: There are no sufficient, well-controlled studies on the use of Butorphanol Tartrate Injection in pregnant women before 37 weeks of pregnancy. It should only be used during pregnancy if the potential benefits to the mother outweigh the possible risks to the baby.
Breast-feeding: Butorphanol has been found in breast milk after nursing mothers are given Butorphanol Tartrate Injection. However, the amount passed to the infant is likely too small to cause harm (about 4 mcg per liter of milk if the mother is receiving 2 mg IM four times a day). When deciding whether to use this medication while breastfeeding, the benefits of breastfeeding should be weighed against the mother's need for the medication and any potential risks to the baby, either from the drug itself or from the condition of the mother.
Infants who are exposed to Butorphanol Tartrate Injection through breast milk should be closely monitored for signs of excessive drowsiness and difficulty breathing. Withdrawal symptoms may occur in breastfed infants when the mother stops taking the opioid pain medication or when breastfeeding is discontinued.
