What does overdosage mean?
An overdosage is an excessive dose of a medicine, drug, poison, or other substance, or the act of administering or taking a dose beyond what is intended or safe. The word is especially common in medicine, pharmacology, toxicology, public-health discussion, and accident reporting, where it can describe a dosing error, an unsafe quantity, or the event of giving or taking too much. In everyday speech, the related term overdose is often more familiar, particularly when the focus is a poisoning case or its potentially severe consequences. Overdosage can also refer broadly to taking an excessive amount of a substance rather than to the clinical condition produced by it. Because it can denote both the amount and the act, its precise meaning depends on context. Knowing the word is useful in safety warnings, medical literature, and descriptions of preventable harm, where precision about excessive exposure is important.
