What do FAERS reports show?
345 reports list acetic acid among the medicines taken, each a report of something that happened, not proof the medicine caused it; 28 are coded as a death and 125 as a hospital stay. Counts follow how widely a medicine is used and watched, and they are not a measure of how risky it is. Of the 23 reactions below, none is named by the same term (in US spelling) in the label's adverse reactions, warnings or patient leaflet; a reaction the label does not name may still be there under another word, and a report does not show that the medicine caused it.
