How long does betamethasone take to be effective?

• A. 6 hours
• B. 12 hours
• C. 24 hours
• D. 48 hours

Answer: (C)

Betamethasone works by altering gene expression to decrease inflammatory mediators, so its effect isn’t immediate. You typically see the first noticeable anti-inflammatory response about 24 hours after starting therapy, with continued improvement over the following days. That’s why 24 hours is the best estimate. Shorter times like 6 or 12 hours are unlikely to reflect the initial onset, and while some improvement may continue to evolve beyond 24 hours, the expected onset is around a day.
