Pregnancy
- Only a very small amount of the medicine reaches your bloodstream and almost none reaches your baby.
- Even if a little does reach your baby, it will not harm them.
Breastfeeding
- There is no information on beclometasone and breastfeeding, but when it's used as a nasal spray only tiny amounts are likely to get into breast milk.
- Side effects in your baby are very unlikely.
- As soon as you can, get in touch with your health visitor, midwife, pharmacist or doctor if your baby is feeding less well than normal, or if anything else about your baby worries you.

The US drug label says
8.1 Pregnancy Risk Summary There are no adequate and well-controlled studies with QNASL Nasal Aerosol or beclomethasone dipropionate in pregnant women. No published studies, including studies of large birth registries, have to date related the use of inhaled corticosteroids (ICS) or intranasal corticosteroids to any increases in congenital malformations or other adverse perinatal outcomes. Thus, available human data do not establish the presence or absence of drug‑associated risk to the fetus. In animal reproduction studies, beclomethasone dipropionate resulted in adverse developmental effects in mice and rabbits at subcutaneous doses equal to or greater than approximately 1.5 times the maximum recommended human dose (MRHD) in adults (0.32 mg/day) (see Data) . In rats exposed to beclomethasone dipropionate by inhalation, dose‑related gross injury to the fetal adrenal glands was observed at doses greater than 350 times the MRHD, but there was no evidence of external or skeletal malformations or embryolethality at inhalation doses of up to 860 times the MRHD. The estimated background risk of major birth defects and miscarriage for the indicated population(s) are unknown.

LactMed says
Although not measured, the amounts of inhaled corticosteroids absorbed into the maternal bloodstream and excreted into breastmilk are probably too small to affect a breastfed infant. Expert opinion considers inhaled, nasal and oral corticosteroids acceptable to use during breastfeeding.[1,2]

The US prescribing label says
8.2 Lactation Risk Summary There are no data available on the presence of beclomethasone dipropionate in human milk, the effects on the breastfed child, or the effects on milk production. However, other corticosteroids have been detected in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for QNASL and any potential adverse effects on the breastfed child from beclomethasone dipropionate or from the underlying maternal condition.
