Disulfiram-alcohol reaction duration can last up to how long?

Explanation:
The key idea is that disulfiram blocks aldehyde dehydrogenase, so after any alcohol is consumed, acetaldehyde builds up and causes the unpleasant reaction. How long that reaction lasts depends on how long acetaldehyde remains elevated while ALDH is inhibited. Since the inhibition persists for a period after drinking, the symptoms typically endure for several hours rather than minutes or days. Therefore, several hours is the best answer.
