Budesonide nasal spray and pregnancy
Budesonide nasal spray can be used during pregnancy.
Very little of the medicine gets into your bloodstream and almost none gets to your baby. Even if a small amount does get to your baby, it will not harm them.
Budesonide nasal spray and breastfeedingIt's OK to use budesonide nasal spray while breastfeeding.
Only tiny amounts get into breast milk, so side effects in your baby are very unlikely.
If you notice that your baby is not feeding as well as usual, or if you have any other concerns about your baby, talk to your health visitor, midwife, pharmacist or doctor as soon as possible.
Budesonide nasal spray and fertilityThere's no evidence that using budesonide nasal spray reduces fertility in either men or women.
