Cephalexin in pregnancy dose

Cefalexin and pregnancy

You can take cefalexin at any stage during pregnancy.

There's no evidence that it causes harm to the baby.

It's important to treat infection during pregnancy as there's a risk that it could make you unwell if left untreated.

Cefalexin and breastfeeding

It's OK for you to take cefalexin while breastfeeding.

Only tiny amounts of cefalexin get into breast milk, so it does not normally cause any side effects in your baby.

However, it has caused diarrhoea in a few infants.

It's important to treat an infection while you're breastfeeding as there's a risk that it could make you unwell if left untreated.

Talk to your health visitor, midwife, doctor or pharmacist as soon as possible if you have any concerns, including if your baby:

• is not feeding as well as usual
• has sickness or diarrhoea
• has oral thrush (a fungal infection in their mouth) or a skin rash

Cefalexin and fertility

There's no evidence to suggest that cefalexin affects fertility in men or women.
