Ventolin Expectorant Use In Pregnancy & Lactation

Fertility: There is no information on the effects of salbutamol on human fertility. There were no adverse effects on fertility in animals (see Pharmacology: Toxicology: Non-clinical Information under Actions). There is no information on the effects of guaifenesin on human fertility.
Pregnancy: Administration of drugs during pregnancy should only be considered if the expected benefit to the mother is greater than any possible risk to the foetus.
During worldwide marketing experience, rare cases of various congenital anomalies, including cleft palate and limb defects have been reported in the offspring of patients being treated with salbutamol. Some of the mothers were taking multiple medications during their pregnancies. Because no consistent pattern of defects can be discerned, and baseline rate for congenital anomalies is 2-3%, a relationship with salbutamol use cannot be established.
The safety of guaiphenesin during pregnancy has not been established.
Lactation: As salbutamol is probably secreted in breast milk its use in nursing mothers is not recommended unless the expected benefits outweigh any potential risk. It is not known whether salbutamol in breast milk has a harmful effect on the neonate.
