What do FAERS reports show?

32,864 reports list tenofovir disoproxil among the medicines taken, each a report of something that happened, not proof the medicine caused it; 1,940 are coded as a death and 6,381 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. Reports rose sharply in 2020 (12,182, against a median of 1,322 a year): FAERS counts follow reporting, which news, litigation and label changes can drive, not how often a reaction happens. Of the 23 reactions below, 5 are 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.
