Monitoring Parameters Monitor WBC, signs and symptoms of infection and renal function.
Lactation: excretion in milk unknown; do not use unless benefit to mother outweighs risk
Pregnancy-Lactation
Pregnancy
Limited available human data with use in pregnant women are insufficient to inform an associated risk of miscarriages, major birth defects, and/or adverse maternal or fetal outcomes; based on animal studies with gemifloxacin, therapy, may cause fetal harm; in animal reproduction studies, administration of drug to pregnant mice and rabbits during the period of organogenesis produced embryofetal toxicity at exposures up to 2 and 3 times, respectively, the maximum recommended human dose; advise pregnant women of potential risk to fetus
Lactation
There is no data on presence of gemifloxacin in human milk, effects on milk production, on breastfed infant; drug is excreted in breast milk of rats; developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed child from treatment or from underlying maternal condition
Interactions
Additive effect on QT interval prolongation w/ class IA (e.g. quinidine) or class III (e.g. amiodarone) antiarrhythmics and other drugs that prolong QT interval (e.g. erythromycin, TCAs, antipsychotic agents). Renal clearance reduced w/ probenecid. Decreased absorption w/ Al or Mg-containing antacids, buffered didanosine, sucralfate or dietary supplements containing metal cations (e.g. Zn, Mg, Fe).
Increased risk of severe tendon disorders esp in elderly (>60 yr) w/ corticosteroids. May increase prothrombin time, INR and/or bleeding w/ warfarin.
