Phenoxymethylpenicillin and pregnancy
It's safe to take phenoxymethylpenicillin during pregnancy.
Phenoxymethylpenicillin and breastfeeding
It's OK to take phenoxymethylpenicillin while breastfeeding.
Evidence shows that only tiny amounts of phenoxymethylpenicillin get into breast milk and it would not be expected to cause any side effects in your baby.
If your baby is not feeding as well as usual, has sickness or diarrhoea, oral thrush (mouth thrush) or a skin rash, or if you have any other concerns about your baby, talk to your doctor, pharmacist, health visitor or midwife.
Phenoxymethylpenicillin and fertility
There's no evidence to suggest that taking phenoxymethylpenicillin reduces fertility in either men or women.
