Pregnancy, breastfeeding and fertility while taking prochlorperazine

Prochlorperazine can be taken in pregnancy. There's no evidence that it will harm your baby.

There are a number of medicines available for treating pregnancy sickness. Talk to your doctor or pharmacist about which medicine would be best for you.

If your doctor, health visitor or midwife says your baby is healthy, you can usually take prochlorperazine if you're breastfeeding.

It's not known how much prochlorperazine passes into breast milk, but it's only likely to be a small amount. Your baby will not be able to absorb a lot into their body from the breast milk, and is unlikely to get side effects. However, it's better to only take it occasionally, or for a short time.

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

• unusually sleepy
• behaving differently, for example being irritable
• not feeding as well as usual or not waking to feed

Prochlorperazine can increase levels of a hormone called prolactin. If levels of prolactin become too high this can cause periods to stop in women and erectile dysfunction (impotence) in men.

However, this is not usually an issue if you take prochlorperazine for a short time to treat sickness.

If you have any concerns about this, speak to your doctor.

Tell your doctor if you're:

• trying to get pregnant
• pregnant
• breastfeeding
