Pregnancy, breastfeeding and fertility while taking bumetanide

Bumetanide and pregnancy

Bumetanide is not usually taken in pregnancy, but you can take it if your doctor thinks it is OK.

If you're trying to get pregnant or are already pregnant, talk to your doctor about whether taking bumetanide is right for you. Continue taking bumetanide until you have been reviewed.

Bumetanide and breastfeeding

Bumetanide is not usually recommended while you're breastfeeding. It would not be expected to cause any side effects in your baby but bumetanide may reduce the amount of breast milk you produce.

It is not known if bumetanide passes into breast milk.

If you're breastfeeding or planning to breastfeed, talk to your doctor or pharmacist as other medicines might be better while breastfeeding.

If you do need to take bumetanide while you're breastfeeding, your doctor and midwife will monitor your baby's weight.

If you notice that your baby is not feeding as well as usual or if you have any other concerns about your baby, then talk to your health visitor, midwife, pharmacist or doctor as soon as possible.

Bumetanide and fertility

There's no evidence that bumetanide reduces fertility in men or women.

However, if you're trying to get pregnant, talk to your doctor first as this medicine is usually not recommended in pregnancy.

It is strongly recommended that you discuss pregnancy with your doctor if you are on treatment for heart failure. They will need to review your medical condition and medicine before you try for a baby.

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

  • trying to get pregnant
  • pregnant
  • breastfeeding
