Patients were randomly assigned to tranexamic acid treatment group or placebo group. After consenting, patients received TXA (100 mg/1mL) or 0.9% sodium chloride (1 mL) in to the affected nostril(s) via intranasal atomization device. If bleeding did not cease, two repeat doses were allowed and after twenty minutes of continued bleeding the study physician could treat with any additional treatment options. Patients were contacted via telephone within one week to inquire about incidences of re-bleeding or any complications.
