Management of haemorrhage due to the administration of a fibrinolytic agent.
Haemorrhage following trauma
The usual dosage is 500mg to 1g by slow intravenous injection (1ml/minute) two to three times daily.
This may be followed by 25 to 50mg/kg/day by intravenous (unlicensed).
1g tranexamic acid by slow intravenous injection (1ml/minute) every 6 to 8 hours, equivalent to 15mg/kg body weight.
Treatment and prevention of trauma-induced haemorrhage (unlicensed)
Initial dose: 1g given over ten minutes by intravenous injection. Start within 8 hours of the trauma.
Maintenance dose: 1g given over 8 hours by continuous intravenous infusion (unlicensed).
Children aged 1 year and older
The dosage is in the region of 20mg/kg/day. However, data on efficacy, posology and safety are limited.
The following alternative unlicensed dosage schedule may be suitable:
Inhibition of fibrinolysis, hereditary angioedema
By intravenous injection over at least 10 minutes
10mg/kg (maximum per dose 1g), two to three times daily.
By continuous intravenous infusion (unlicensed)
45mg/kg, dose to be given over 24 hours.
Prevention of excessive bleeding after dental procedures (e.g. in haemophilia)
By intravenous injection pre-operatively
Children aged 6 to 18 years: 10mg/kg (maximum per dose 1.5g).
Patients with Renal Impairment
The manufacturer recommends the dosage should be reduced as follows:
Serum creatinine 120 to 249micromole/L: 10mg/kg every 12 hours.
Serum creatinine 250 to 500micromole/L: 10mg/kg every 24 hours.
Serum creatinine greater than 500micromole/L: 5mg/kg every 24 hours.
The Renal Drug Handbook suggests the following doses:
Glomerular filtration rate (GFR)
GFR 20 to 50mL/minute: 10mg/kg 12 hourly.
GFR 10 to 20mL/minute: 10mg/kg 24 hourly.
GFR less than 10mL/minute: 5mg/kg 24 hourly.
For slow intravenous injection or infusion (1ml/minute) or continuous intravenous infusion (unlicensed) administration.
Disseminated intravascular coagulation without reactive major fibrinolysis

Do not mix with other drugs or substances
During prolonged therapy eye examinations are advisable
Monitor hepatic function in patients with hereditary angioneurotic oedema
Advise patient to report any blurred vision or any other eye symptoms
Discontinue if any kind of visual disturbance occurs
Female: Ensure adequate contraception during treatment
Massive haemorrhage from upper urinary tract, risk of urethral obstruction has been reported (especially in haemophilia).
Before use of tranexamic acid, risk factors for thromboembolic disease should be investigated.
Tranexamic acid should be administered with care in patients receiving oral contraceptives due to an increased risk of thrombosis.
Tranexamic acid should only be considered in patients with disseminated intravascular coagulation when appropriate haematological laboratory facilities are available.
Pregnancy and Lactation
Use tranexamic acid with caution during pregnancy.
The manufacturer does not recommend using tranexamic acid during the first trimester of pregnancy, and should only be used throughout pregnancy if the expected benefit justifies the potential risk. At the time of writing there is limited published information regarding the use of tranexamic acid during pregnancy. Potential risks are unknown.
Tranexamic acid is contraindicated during breastfeeding.
Use of tranexamic acid when breastfeeding is contraindicated by the manufacturer. Tranexamic acid is present in human breast milk. Effects on exposed infants are unknown.
Allergic skin reactions
Macular degeneration of colour vision
It is strongly recommended that the UK National Poisons Information Service be consulted on cases of suspected or actual overdose where there is doubt over the degree of risk or about appropriate management.
