In acetaminophen poisoning, when do initial symptoms typically appear?

Explanation:
In acetaminophen overdose, the earliest signs are nonspecific and often appear within the first several hours after ingestion. The initial symptoms are typically mild GI upset—nausea, vomiting, malaise—that can begin as early as about 4 to 12 hours after ingestion. This early phase happens before any marked liver injury is evident. Shortly thereafter, many patients enter a brief asymptomatic or latent period, and then more significant hepatotoxic effects can develop 24 to 48 hours later with worsening liver function. So, the best-fit timing for the onset of initial symptoms is around 4 to 12 hours after ingestion.
