What is the TXA dosing regimen described for obstetric hemorrhage?

• A. 1 g IV over 10 minutes; second dose if bleeding persists
• B. 2 g IV over 30 minutes
• C. 1 g IV bolus only
• D. 500 mg IV push

Answer: (A)

The key idea here is how tranexamic acid is used to control obstetric hemorrhage. The standard regimen is a 1-gram intravenous dose given over about 10 minutes, with a second 1-gram dose if the bleeding persists. This approach, backed by obstetric hemorrhage guidelines and trials, emphasizes early administration to reduce mortality from bleeding. The second dose is only given if bleeding continues, so the total dose can be up to 2 grams but not given all at once in a single large infusion.
