What should you know about TXA for epistaxis?

Epistaxis is bleeding from the inside of the nose, often from fragile blood vessels near the front of the nasal septum. Dry air, nose picking, forceful blowing, irritation from a cold or allergic rhinitis, sinus inflammation, injury, and medicines that affect clotting can contribute. Tranexamic acid, or TXA, slows the breakdown of a developing clot. A clinician may apply it locally or prescribe it in a selected situation, depending on the bleeding, medical history, and local practice. TXA does not replace checking the source of bleeding or managing blood pressure and other contributing factors when relevant.

Sit upright, lean slightly forward, and breathe through your mouth. Pinch the soft part of the nose continuously for a sustained period without checking too early. Spitting out blood is safer than swallowing it. If bleeding continues, a clinician may clean the nose, use a topical treatment such as TXA, or place a nasal dressing. Do not insert tissues or hard objects deep into the nose. Avoid forceful blowing, heavy exertion, and picking while the area heals. Use TXA only as directed, especially if you have a history of clotting problems or take anticoagulants.

Seek urgent help if bleeding is heavy, follows a significant injury, makes you faint or breathless, flows into the throat, or does not settle with firm pressure. Repeated nosebleeds, bleeding from several sites, easy bruising, or known high blood pressure need medical review. Emergency assessment is also appropriate if you take blood-thinning medicine and cannot control the bleeding.

Ask whether TXA is suitable for the source and duration of your bleeding, how it should be applied, and what side effects matter. Ask whether dryness, rhinitis, sinusitis, blood pressure, injury, or another medicine may be contributing.
