Infobord.png More information
  • Clozapine is generally considered to be more effective than other antipsychotic drugs. Clozapine is often used in treatment-resistant schizophrenia (poor treatment response to 2 or more antipsychotic drugs). So a switch from clozapine to another antipsychotic drug could cause problems regarding effectiveness.[4][5][6]
  • During this switch you could monitor ECG, especially in patients prone to QT-conduction problems.
  • There is a possibility of QT interval prolongation.[7]
  • 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.
