  • During this switch you could monitor ECG, especially in patients prone to QT-conduction problems.
  • There is a possibility of QT interval prolongation.[3]
  • Alternatively, first switch to oral form and then switch to depot to manage possible (adverse) reactions. With a direct switch to a depot it is advisable to administer a low testdose in order to exclude adverse reactions.
