/api/v1/reaction/paradoxical-drug-reactionReference statistics only. FAERS reports are voluntarily submitted and are not incidence rates, safety signals, or causal evidence. The drugs below are ranked by how often this reaction appears on FAERS reports for each drug — high share does not mean the drug caused the reaction, and absence from this list does not mean the reaction never occurred. This is not a symptom checker.
