Study Population
Patients with schizophrenia treated with atypical antipsychotics (AAPs) to stay in remission

Inclusion Criteria:

  • Diagnosis of schizophrenia
  • Treatment with one atypical antipsychotic* (for a first/new episode or a switch of therapy) for at least 2 weeks and maximum 8 weeks prior to the first study visit.
  • Patient takes an AAP according to local SPC and current medical practice
  • The patient must be able to understand and comply with the study requirements as judged by the investigator, e.g. patient must be able to read and write

Exclusion Criteria:

  • Treatment with an additional AAP or AP to the initial prescribed AAP within the 2-8 weeks before the patient is included in the study
  • Since the use of clozapine is limited, due to, among other things, the risk for agranulocytosis, patients on treatment with this '2nd line'AAP are excluded.
  • Previous enrolment or treatment in the present NIS
  • Known allergy to the prescribed AAP or any of its substances
