Tell your doctor if you are pregnant or plan to become pregnant. It is not known whether albuterol will harm an unborn baby. However, having uncontrolled asthma during pregnancy may increase the risk of premature birth, low birth weight, or eclampsia (dangerously high blood pressure that can lead to medical problems in both mother and baby). The benefit of preventing bronchospasm may outweigh any risks to the baby. If you are pregnant, your name may be listed on a pregnancy registry to track the effects of albuterol on the baby. It may not be safe to breastfeed while using this medicine. Ask your doctor about any risk.
