Mechanism of Action
- For Patients: Tranexamic acid helps your blood to clot by stopping the breakdown of clots. This means it can help slow or stop excessive bleeding in certain conditions.
- For Specialists: Tranexamic acid is a synthetic lysine analogue that competitively inhibits plasminogen activation and, at higher doses, non-competitively inhibits plasmin, preventing fibrin degradation and stabilising blood clots.
Pharmacokinetics
- Absorption: Rapidly absorbed after oral administration; peak blood concentration within 2-3 hours.
- Distribution: Low protein binding; crosses into all bodily fluids.
- Metabolism: Minimal hepatic metabolism; mostly excreted unchanged.
- Elimination: Mainly via urine (renal excretion); half-life approx. 2-3 hours.
- Duration of Action: Effect lasts 6-8 hours, may vary by indication and patient.
Everyday Use and Best Practices
Typical Doses
- For heavy menstrual bleeding: 1,000 mg (2 × 500 mg tablets) taken 3 times daily, usually for up to 4 days during the period.
- For dental procedures, nosebleeds, or following trauma/surgery: Dose individualised; follow your doctor’s instructions.
- Always take with a large glass of water. Do not exceed the prescribed dose.
How to Use in an Australian Context
- Take tablets as soon as heavy bleeding starts, not before.
- If you forget a dose, take it as soon as you remember unless it’s nearly time for your next dose.
- Store tablets below 25°C; protect from moisture and heat—room temp is fine in most English homes.
Dosing: Morning vs Evening
- No strict requirement for morning or evening use—dosing interval (every 8 hours) is more important for maintaining consistent blood levels.
- Tip: Take doses at the same time each day for best results (e.g., after breakfast, lunch, and dinner).
- Morning use may suit those with regular routines, but follow your doctor's advice for your bleeding pattern.
- Avoid taking doses too close together or skipping overnight doses unless advised by your doctor.
Taking with Food or on an Empty Stomach
- Can be taken with or without food. Taking with food may reduce stomach upset for some people.
- No special dietary restrictions are needed. Continue with your normal English/Australian diet unless otherwise instructed.
- Drink plenty of water.

Take it as soon as you remember unless it's almost time for your next dose. Do not double up the dose. If unsure, ask your pharmacist for advice. - 4. Can I take Cyklokapron with the Pill (oral contraceptive)?
There may be an increased risk of blood clots if used with hormonal contraceptives. Only combine under medical supervision. - 5. Is Cyklokapron funded or discounted in Australia?
