If overdose occurs the patient must be monitored for evidence of toxicity (see Adverse Reactions). Treatment of overdose with emtricitabine and tenofovir alafenamide fumarate consists of general supportive measures including monitoring of vital signs as well as observation of the clinical status of the patient.
Emtricitabine can be removed by haemodialysis, which removes approximately 30% of the emtricitabine dose over a 3 hour dialysis period starting within 1.5 hours of emtricitabine dosing. Tenofovir is efficiently removed by haemodialysis with an extraction coefficient of approximately 54%. It is not known whether emtricitabine or tenofovir can be removed by peritoneal dialysis.
