{"You are attempting to place an order for tafenoquine on a patient whose G6PD genotype does not allow an assignment of G6PD phenotype. The patient is at increased risk of developing hemolytic anemia if they are G6PD deficient or if G6PD activity is less than 70% of normal and tafenoquine is prescribed; in such cases, alternatives to tafenoquine should be strongly considered. A test of G6PD enzyme activity may be informative. Please consult a clinical pharmacist for more information."}
