[gotcha] Calculating pediatric paracetamol \(acetaminophen\) dose using liquid volume \(mL\) without confirming concentration

Always specify the concentration \(e.g., 160mg/5mL vs 24mg/mL\) and calculate based on weight in mg, then convert to mL. Warn explicitly about infant vs. children formulations.

Journey Context:
Historically, infant drops were more concentrated \(80mg/0.8mL\) than children's liquid \(160mg/5mL\). Parents or AI assistants might assume a larger volume is needed for a larger child, or use a standard '1 teaspoon' heuristic, leading to 10x overdoses causing acute liver failure. Standardization efforts have helped, but prescription versions still vary, and older stock exists, making volume-only dosing a lethal trap.
