TRANEXAMICACID

Indications & Dose:

Local fibrinolysis

BY MOUTH

Adult: 1–1.5 g 2–3 times a day, alternatively 15–25 mg/kg 2–3 times a day

INITIALLY BY SLOW INTRAVENOUS INJECTION

Adult: 0.5–1 g 2–3 times a day, to be administered at a rate not exceeding 100 mg/minute, dose may be followed by continuous infusion; (by continuous intravenous infusion) 25–50 mg/kg, dose to be given over 24 hours

Menorrhagia

initiated when menstruation has started; maximum 4 g per day

Hereditary angioedema

l BY MOUTh

Adult: 1–1.5 g 2–3 times a day, for short-term prophylaxis of hereditary angioedema, tranexamic acid is started several days before planned procedures which may trigger an acute attack of hereditary angioedema (e.g.dental work) and continued for 2–5 days afterwards

Epistaxis BY MOUTHAdult: 1 g 3 times a day for 7 days

General fibrinolysis

BY SLOW INTRAVENOUS INJECTION Adult: 1 g every 6–8 hours, alternatively 15 mg/kg every 6–8 hours, dose to be given at a rate not exceeding 100 mg/minute

Contraindications:

Active thromboembolic disease; history or intrinsic risk of thrombosis or thromboem-bolism, including retinal vein or artery occlusion; hypersensitivity to tranexamic acid or its components

Side Effects:

Vomiting, diarrhea, giddiness on rapid intravenous injection.

Cautions:

Reduce dose in renal impairment; massive haematuria (avoid if risk of ureteric obstruction); regular eye examination and liver function tests in long-term treatment of hereditary angioedema. Note: Requirement for regular eye examination during long-term treatment is based on unsatisfactory evidence.

Precautions:

Interaction:
