Lit Matters 2: TXA in Non-traumatic Epistaxis

Most non-traumatic anterior epistaxis stops with compression, but persistent bleeding still drives major practice variation in the ED. Topical tranexamic acid appears comparable to lidocaine and epinephrine for getting packed anterior nosebleeds under control, while the basics of pressure, packing, cautery, and coagulopathy reversal still matter most.

Topical Therapy for Anterior Epistaxis

• Compression first principle: Most spontaneous anterior nosebleeds improve with direct pressure alone; the real decision point is the patient who keeps bleeding despite compression and is headed toward topical therapy or packing.
• Head-to-head topical comparison: In a prospective double-blind randomized trial, topical TXA, lidocaine, and epinephrine had similar bleeding-control times in non-traumatic anterior epistaxis treated with drug-soaked packing.
• No clear TXA advantage: TXA stopped bleeding in about 9 minutes, essentially matching lidocaine and epinephrine rather than outperforming them as a routine first choice for anterior epistaxis.
• Side effect signal: Epinephrine did not show the feared systemic blood pressure downside in this study, while the TXA group actually had a slight blood pressure increase.
• Study population limits: Key exclusions included anticoagulant use, bleeding disorders, and hypertension, leaving open whether the slow-ooze anticoagulated patient is the subgroup where TXA may still matter. We get into that bedside distinction in the episode.
• Back-to-basics management: When anterior epistaxis persists, fundamentals still carry the case: firm pressure, thoughtful packing, cautery when needed, and reversal of coagulopathy when it is driving the bleed.
