Tolterodine and pregnancy
Tolterodine is not usually recommended in pregnancy because there's not enough information available to say if it's safe for you and your baby.
If you're trying to get pregnant or you're already pregnant, talk to your doctor about whether taking tolterodine is right for you.
Tolterodine and breastfeeding
If your baby is healthy, you can take tolterodine if you need to while you're breastfeeding. However, other medicines might be better. Your doctor or pharmacist will help you decide.
It's not known how much tolterodine gets into breast milk, but it's likely to be very low levels.
It's very rare for breastfed babies to have side effects from medicines you're taking. But it's important to keep monitoring your baby if you're taking any medicine while breastfeeding.
Contact your healthcare professional or call 111 as soon as possible if you notice that your baby:
- is not feeding as normal or gaining weight as expected
- is behaving differently, for example being irritable or unusually sleepy
- has difficulty pooing (constipation) or is peeing less (fewer wet nappies)
- has diarrhoea, or is being sick (vomiting)
- has dry skin
If your baby has any symptoms that are not listed, or if you're worried about them, you can also call 111 or contact any healthcare professional.
Carry on taking the medicine, and keep breastfeeding as usual until you've got advice about your baby's symptoms.
Tolterodine and fertility
There's no evidence to suggest that taking tolterodine will affect fertility in either men or women.
However, speak to a pharmacist or your doctor before taking it if you're trying to get pregnant.
