Tranexamic acid while breastfeeding

A small amount of medicine may pass into breast milk, so the decision depends on the clinical situation rather than breastfeeding alone. Tranexamic acid is used to help control bleeding, including heavy bleeding after pregnancy or during periods. The route, formulation, treatment length, kidney function, and other medicines can change the discussion. Do not stop breastfeeding or discard milk without advice from your prescriber, midwife, pharmacist, or the baby’s clinician. A newborn, premature baby, or baby with a medical condition may need individual guidance.

Tell the prescriber that you are breastfeeding, when you delivered, and whether your baby has feeding or health concerns. Share all medicines and supplements, including hormonal contraception and medicines that affect clotting. Take tranexamic acid exactly as directed and watch your baby for feeding difficulty, unusual sleepiness, vomiting, diarrhoea, or a rash. Report concerning changes rather than changing the schedule yourself. Keep follow-up appointments so the bleeding and the need for treatment can be reassessed.

Get urgent help for sudden breathlessness, chest pain, coughing blood, one-sided leg pain or swelling, or new vision changes. Contact your maternity team promptly for bleeding that soaks through protection quickly, large clots, worsening pelvic pain, fever, faintness, or a racing heartbeat. Seek advice for any marked change in your baby’s feeding, alertness, breathing, or skin colour.

Ask why tranexamic acid is recommended, whether you can continue breastfeeding, how to time doses, and what to monitor in your baby. Confirm the planned treatment length and who to contact if bleeding returns after the course.
