Quinine can cause severe adverse reactions, including drug-induced thrombocytopenia, according to an analysis of studies involving 142 individuals.
Investigators searched 11 databases for evidence of a causal link involving quinine, focusing on acute, immune-mediated reactions, and noting organ systems involved, adverse reaction severity, and outcomes. Among the findings:
• ~7 in every 10 reactions were caused by quinine pills; ~3 in every 10 by beverages; and the remainder by other exposures.
• 92 of 101 patients who had non-dermatologic reactions needed to be hospitalized; 30 needed renal replacement therapy, and 3 died.
The authors noted that even small amounts of quinine from common beverages can impact organ systems.
