  • Dosage and administration

Trenstad is indicated in antiretroviral combination therapy for the treatment of HIV-1 and chronic hepatitis B infected adults aged 18 years and over.

  • Known hypersensitivity to emtricitabine, tenofovir disoproxil fumarate or any ingredient in the formulation.

Pregnancy and Lactation:

  • There are reports on pregnant women indicate no malformations or foetal/neonatal toxicity associated with emtricitabine and tenofovir disoproxil fumarate. Animal studies on emtricitabine and tenofovir disoproxil fumarate do not indicate reproductive toxicity. Therefore the use of Trenstad may be considered during pregnancy, if necessary.


  • Emtricitabine and tenofovir have been shown to be excreted in human milk. There is insufficient information on the effects of emtricitabine and tenofovir in newborns/infants. Therefore should not be used during breast-feeding. As a general rule, it is recommended that HIV infected women do not breast-feed their infants in order to avoid transmission of HIV to the infant.

  • The recommended dose is one tablet, once daily.
  • If a patient misses a dose of Trenstad within 12 hours, take one dose with food as soon as possible and resume their normal dosing schedule. If a patient misses a dose of Trenstad by more than 12 hours and it is almost time for the next dose, the patient should not take the missed dose and simply resume the usual dosing schedule.

  • Severe renal impairment (creatinine clearance < 30 ml/min) and haemodialysis patients: Trenstad is not recommended for severe renal impairment and haemodialysis patients.
