Salbutamol inhalers in pregnancy

The NHS says

Salbutamol can be used in pregnancy. Keeping your asthma well treated is important, so do not hold back from using your inhaler when you need it.

Your doctor will advise you to keep using your salbutamol inhaler if you have asthma, and can give you advice on managing your asthma while you're pregnant.

The US drug label says

Pregnancy Teratogenic Effects Pregnancy Teratogenic Effects Pregnancy Category C: Albuterol has been shown to be teratogenic in mice. A study in CD-1 mice at subcutaneous (sc) doses of 0.025, 0.25, and 2.5 mg/kg (approximately 1/100, 1/10, and 1.0 times, respectively, the maximum recommended daily inhalation dose for adults on a mg/m 2 basis), showed cleft palate formation in 5 of 111 (4.5%) fetuses at 0.25 mg/kg and in 10 of 108 (9.3%) fetuses at 2.5 mg/kg. The drug did not induce cleft palate formation at the lowest dose, 0.025 mg/kg. Cleft palate also occurred in 22 of 72 (30.5%) fetuses from females treated with 2.5 mg/kg isoproterenol (positive control) subcutaneously (approximately 1.0 times the maximum recommended daily inhalation dose for adults on a mg/m 2 basis). A reproduction study in Stride Dutch rabbits revealed cranioschisis in 7 of 19 (37%) fetuses when albuterol was administered orally at a 50 mg/kg dose (approximately 80 times the maximum recommended daily inhalation dose for adults on a mg/m 2 basis). There are no adequate and well-controlled studies in pregnant women.

Salbutamol inhalers while breastfeeding

The NHS says

You can use your salbutamol inhaler as normal while breastfeeding.

Carrying on treating your asthma is important to keep you well, and breastfeeding also benefits you both.

The amount of salbutamol that reaches breast milk is not known, but the levels are likely to be very low. It has been used widely by breastfeeding mothers for many years without causing side effects in breastfed babies.

Side effects in breastfed babies from medicines their mother takes are very rare, but it's important to keep an eye on your baby whenever you take medicines while breastfeeding.

Contact a healthcare professional or call 111 (NHS 111 in the UK) as soon as you can if your baby is feeding less well than normal.

For symptoms not mentioned here, or if you're worried about your baby, you can also speak to any healthcare professional or call 111.

Keep using the medicine and carry on breastfeeding as normal until you've had advice about your baby's symptoms.

LactMed says

Although no published data exist on the use of albuterol by mouth or inhaler during lactation, data from the related drug, terbutaline, indicate that very little is expected to be excreted into breastmilk.[1-3] The authors of several reviews and expert guidelines agree that use of inhaled bronchodilators is acceptable during breastfeeding because of the low bioavailability and maternal serum levels after use.[4-7]

“Summary of Use during Lactation”, LactMed record “Albuterol” (LM6), quoted verbatim. Everything LactMed reports about Albuterol while breastfeeding.

The US prescribing label says

Nursing Mothers: It is not known whether this drug is excreted in human milk. Because of the potential for tumorigenicity shown for albuterol in some animal studies, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
