Adverse effects

Clinical studies have reported a higher incidence of drug-induced liver injury in women with certain drugs such as nitrofurantoin, flucloxacillin, erythromycin and isoniazid [1]. Several retrospective observational studies have reported a female preponderance in flucloxacillin-induced liver injury. However, numbers of reported cases have been small and the differences between men and women have not reached statistical significance. [2-4]. A UK study of flucloxacillin-induced drug-induced liver injury (15 men, 36 women) showed association with HLA-B*5701 genotype [4].
