FDA labels and FAERS
Side effects: labels and reports
FAERS reports for 2,014 medicines through July 30, 2026, beside each label's own adverse-reactions text. A FAERS report records that someone took the medicine and something happened. It does not show that the medicine caused it, and counts follow how widely a medicine is used and watched; they are not a measure of how risky it is.
