What should you know about intravenous tranexamic acid?

After a clot forms, the body gradually breaks it down. Tranexamic acid slows that breakdown, which can help bleeding settle. Intravenous treatment is used when a rapid, supervised route is needed, such as significant bleeding around childbirth, surgery, or another urgent situation. It does not replace treatment of the cause of bleeding.

A clinician chooses the dose and timing after considering the source and severity of bleeding, kidney function, previous clotting problems, and other medicines. The injection may be given slowly through a cannula. Nausea, vomiting, dizziness, or changes at the injection site can occur, so tell staff about new symptoms.

Tell the treating team if you have had a blood clot, kidney disease, seizures, or a reaction to tranexamic acid. Provide a full list of medicines, including hormonal contraception and medicines that affect clotting. Keep the cannula protected and report pain, swelling, or burning around it.

Continue the assessment recommended for the bleeding source. Tranexamic acid may reduce blood loss while other care is arranged, but it is not a substitute for examination, imaging, surgery, fluids, or treatment of an underlying condition when those are needed.

Seek emergency help for heavy bleeding with faintness, confusion, severe weakness, or breathlessness. After treatment, urgent assessment is needed for sudden chest pain, difficulty breathing, coughing blood, one-sided leg swelling or pain, or a new severe headache with visual or neurological changes.

These warning symptoms can have causes other than the medicine, but they should not be watched at home. If bleeding continues or returns, contact the service that treated you for specific instructions.

Ask what is causing the bleeding, why an intravenous route is preferred, how quickly the medicine should work, and what other treatment may be needed. Check whether your kidney function or clot history changes the plan.
