About this information

This NHS content is written for people in England. Medicine names, availability, prescribing and services may differ in other countries.

Salbutamol and pregnancy

Salbutamol can be used in pregnancy. It's important that your asthma is well treated, so do not hesitate to use your inhaler if you need it.

If you have asthma, your doctor will recommend that you continue to use your salbutamol inhaler. They will be able to give you advice on how to manage your asthma during pregnancy.

If your asthma gets worse, let your midwife or doctor know, as your treatment may need to be increased.

Salbutamol and breastfeeding

It's OK to use your salbutamol inhaler as normal while you're breastfeeding.

It's important that you continue to treat your asthma to keep you well. Breastfeeding will also benefit both you and your baby.

It's not known how much salbutamol gets into breast milk, but it's likely to be very low levels. For many years it has been widely used while breastfeeding without causing any side effects in breastfed babies.

It's very rare for breastfed babies to have side effects from medicines you're taking. But it's important to keep monitoring your baby if you're taking any medicines while breastfeeding.

Contact your healthcare professional or call 111 as soon as possible if your baby is not feeding as well as usual.

If your baby has any symptoms that are not listed, or if you're worried about them, you can also call 111 or contact any healthcare professional.

Carry on taking the medicine and keep breastfeeding as usual until you've got advice about your baby's symptoms.
