From the Research

G6PD Deficiency and Tonic Water Consumption

  • There is no direct evidence in the provided studies that specifically addresses the consumption of tonic water by individuals with G6PD deficiency 1, 2, 3, 4, 5.
  • However, it is known that G6PD deficiency makes red cells highly vulnerable to oxidative damage, and certain substances can trigger hemolysis in individuals with this condition 1, 2, 3.
  • Tonic water typically contains quinine, which is a substance that can cause oxidative stress 4.
  • Although quinine is not explicitly mentioned as a substance that should be avoided in individuals with G6PD deficiency in the provided studies, it is possible that it could trigger hemolysis in some cases.
  • The studies do provide a list of medications that should be avoided in individuals with G6PD deficiency, but tonic water is not mentioned as a specific substance to avoid 4.
  • It is essential to note that the management of G6PD deficiency involves preventing hemolysis by avoiding oxidative stress, and individuals with this condition should be cautious when consuming substances that may trigger oxidative damage 3, 5.
