Oxybutynin and pregnancy
Oxybutynin is occasionally used in pregnancy when bladder symptoms are severe and cannot be controlled any other way.
If you're pregnant or trying to get pregnant, talk to your doctor about whether taking oxybutynin is right for you.
Oxybutynin and breastfeeding
It's OK to take oxybutynin if you're breastfeeding, but talk to your doctor first.
It's not known how much oxybutynin gets into breast milk, but it's likely to be a tiny amount. Your baby will not be able to absorb a lot into their body from the breast milk, and it should not cause them any side effects.
As a precaution, talk to your health visitor, midwife, doctor, or pharmacist or call 111 as soon as possible if you have any concerns about your baby, including if they:
- are not feeding as well as usual or not putting on weight as you would expect
- are unusually sleepy or irritable
- have constipation or are peeing less (fewer wet nappies)
