Pregnancy, breastfeeding and fertility while taking baclofen

Balofen and pregnancy

Baclofen is not often recommended in pregnancy. However, if you need baclofen to stay well, your doctor may recommend that you keep taking it.

Talk to your doctor about the benefits and possible risks of taking baclofen in pregnancy. If you take it in later pregnancy your baby may need to be monitored for withdrawal symptoms.

If you become pregnant while taking baclofen then contact your doctor. They may recommend reducing your dose or gradually stopping the medicine.

Baclofen and breastfeeding

If your doctor or health visitor says your baby is healthy, you can take baclofen while you're breastfeeding. It's important to keep taking baclofen to keep you well.

There is not much information about taking baclofen while breastfeeding, but information shows that it passes into breast milk in small amounts. It has not been known to cause any side effects in breastfed babies.

Contact your health visitor, midwife, pharmacist or doctor as soon as possible if your baby:

  • is not feeding as well as usual or seems to have a dry mouth
  • seems unusually sleepy
  • is sweaty or develops a rash
  • is being sick or has diarrhoea
  • is causing you any other concerns

Baclofen and fertility

There's no evidence to suggest that taking baclofen will reduce fertility in either men or women.

But speak to a pharmacist or your doctor if you're trying to get pregnant.

Non-urgent advice: Tell your doctor if you're:

  • trying to get pregnant
  • pregnant
  • breastfeeding
