Pregnancy, breastfeeding and fertility while taking cyclizine

Cyclizine and pregnancy

Cyclizine is commonly used to treat pregnancy sickness and there is no evidence that it can harm your baby.

Cyclizine and breastfeeding

If your doctor or health visitor says your baby is healthy, you can take cyclizine while you're breastfeeding, but it's best to only take occasional doses, or for a short time.

It is not known how much cyclizine passes into breast milk, but it is unlikely to cause side effects in your baby. However, if taken for longer periods of time, it might make your baby sleepy.

Talk to your doctor, as other medicines might be better while you're breastfeeding.

If your baby is not feeding as well as usual, seems unusually sleepy, or seems irritable, or if you have any other concerns about your baby, talk to your doctor, pharmacist, health visitor or midwife.

Cyclizine and fertility

Cyclizine does not affect fertility in either men or women.
