Detailed medicine guidance

Pregnancy, breastfeeding and fertility while taking tranexamic acid

NHS medicines information on tranexamic acid and whether you can take it while pregnant or breastfeeding.

About this information

This NHS content is written for people in England. Medicine names, availability, prescribing and services may differ in other countries.

Tranexamic acid and pregnancy

Tranexamic acid is not often recommended in pregnancy but it can be taken if needed. Only take it if it's been prescribed by a doctor.

If you're pregnant or trying to get pregnant, speak to your doctor. They may want to review your medicine.

You may sometimes be given tranexamic acid after your baby is born. You may need it if you have too much bleeding around the time of the birth, or if you have a problem with your blood that makes you more likely to bleed. Your maternity team will be able to explain this.

Tranexamic acid and breastfeeding

If your doctor, midwife or health visitor says your baby is healthy, it's OK to take tranexamic acid if you're breastfeeding.

There is not much information about taking tranexamic acid while breastfeeding, but it shows that tranexamic acid passes into breast milk in very small amounts, and does not usually cause any side effects in babies.

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

  • not feeding as well as usual
  • being more restless than usual
  • being sick or have diarrhoea
Tranexamic acid and fertility

There's no evidence to suggest that taking tranexamic acid reduces fertility in either men or women.
