Monitoring considerations with ROZLYTREK1

  • Patients receiving ROZLYTREK should be carefully monitored for clinical signs and symptoms of congestive heart failure, including shortness of breath or oedema
  • ROZLYTREK should be avoided in patients with congenital long QTc syndrome and in patients taking medications that are known to prolong QTc interval:
    • Baseline and periodic monitoring of electrocardiograms and electrolytes is recommended
  • Patients should be monitored for signs of cognitive changes

This medicinal product is subject to additional monitoring. This will allow quick identification of new safety information. Healthcare professionals are asked to report any suspected adverse reactions. See section 4.8 of the SmPC for details on how to report adverse reactions.


ALT, alanine aminotransferase; AST, aspartate aminotransferase; QT, time from the start of the Q wave to the end of the T wave; QTc, the corrected QT interval; TRAE, treatment-related adverse event.
