The recommended starting dose is a  1 mg capsule taken orally once daily

0.25 mg capsule1

Available for patients who require dose modifications

Capsules not actual size (~5 mm x ~14 mm).Administration considerations1Dose reduction schedule
  • To manage adverse reactions, consider interruption of treatment or dose reduction based on severity and clinical presentation1
Capsules not actual size (~5 mm x ~14 mm).Please refer to SmPC for complete information on dose modifications for TALZENNA®.​Special populations Hepatic impairment1
  • No dose modification is recommended for patients with mild, moderate, or severe hepatic impairment (based on NCI criteria)
Renal impairment1
  • No dose adjustment is required for patients with mild renal impairment (60 mL/min ≤ CrCL <90 mL/min)
  • For patients with moderate renal impairment (30 mL/min ≤ CrCL <60 mL/min), the recommended starting dose of TALZENNA® is 0.75 mg once daily
  • For patients with severe renal impairment (15 mL/min ≤ CrCL <30 mL/min), the recommended starting dose of TALZENNA® is 0.5 mg once daily
  • TALZENNA® has not been studied in patients with CrCL <15 mL/min or patients requiring hemodialysis
  • No dose adjustment is necessary in elderly (≥65 years of age) patients
Paediatric Population1
  • The safety and efficacy of Talzenna® in children and adolescents <18 years of age have not been established. No data are available.
  • It is unknown whether TALZENNA® is excreted in human breast milk. A risk to breast-fed children cannot be excluded and therefore breastfeeding is not recommended during treatment with TALZENNA® and for at least 1 month after the final dose.
Drug interactionsUse with P-gp inhibitors1
  • Strong inhibitors of P-gp may lead to increased TALZENNA® exposure*
  • Concomitant use of strong P-gp inhibitors during treatment with TALZENNA® should be avoided.
  • Co-administration should only be considered after careful evaluation of the potential benefits and risks.
  • If co-administration with a strong P-gp inhibitor is unavoidable, the TALZENNA® dose should be reduced to the next lowest dose.
  • When the strong P-gp ihibitor is discontinued, the TALZENNA® dose should be increased (after 3-5 half lives of the P-gp inhibitor) to the dose used prior to the initiation of the strong P-gp inhibitor
  • No TALZENNA® dose adjustments are required when co-administered with rifampin
  • However, the effect of other P-gp inducers on TALZENNA® exposure has not been studied
  • Other P-gp inducers (including but not limited to carbamazepine, phenytoin, and St. John’s wort)  may decrease TALZENNA® exposure.
BCRP inhibitors1
  • The effect of BCRP inhibitors on TALZENNA® pharmacokinetics has not been studied in vivo.
  • Co-administration of TALZENNA® with BCRP inhibitors may increase TALZENNA® exposure.
  • Concomitant use of strong BCRP inhibitors (including but not limited to curcumin and cyclosporine) should be avoided.
  • If co-administration of strong BCRP inhibitors cannot be avoided, the patients should be monitored for potential increased adverse reactions.
Effects of systemic hormonal contraception1
  • Drug-drug interaction between TALZENNA® and oral contraceptives have not been conducted.
Effect of acid-reducing agents1
  • Co-administration of acid-reducing agents including proton pump inhibitors, histamine receptor 2 antagonists (H2RA), or other acid-reducing agents had no significant impact on the absorption of TALZENNA®
AE=adverse event; AST=aspartate aminotransferase; BCRP=breast cancer resistance protein; CrCL=creatinine clearance; PFS=progression-free survival; P-gp=P-glycoprotein; ULN=upper limit of normal. Explore more Dose modifications
