March 2014: A correction has been made to the wording of recommendation18.104.22.168 to clarify that it is the hydrocarbons in cigarette smoke that cause interactions with other drugs, rather than nicotine.
February 2014: We have reviewed the evidence and made new recommendations on maintaining and improving physical health, peer support and self-management, preventing psychosis, service-level interventions, employment, education and occupational activities, and supporting carers. These recommendations are marked .
We have also made some changes without an evidence review:
A link has been added to the NICE guideline on service user experience in adult mental health services because that guideline replaces some of the 2009 recommendations on psychosis and schizophrenia.
Some recommendations have been aligned with the NICE guideline on psychosis and schizophrenia in children and young people. This promotes early intervention in psychosis services for young people aged 15 years and over.
Substance misuse has been included as a coexisting condition that should be looked for.
A recommendation has been amended to indicate that antipsychotics should not be started in primary care unless under the supervision of a consultant psychiatrist.
A recommendation has been amended to reflect recent terminology relating to ethnic groups and to remove reference to specific agencies.
These recommendations are marked as [2009, amended 2014].
Recommendations marked  last had an evidence review in 2009. In some cases, minor changes have been made to the wording to bring the language and style up to date, without changing the meaning.
Minor updates since publication
November 2022: In recommendation 22.214.171.124 we removed the wording about initially using a small test dose when initiating depot/long-acting injectable antipsychotic medication, as this is no longer always appropriate. See the surveillance report for more information.
December 2021: Following a surveillance review we have updated recommendations 126.96.36.199 and 188.8.131.52 to say that either glycosylated haemoglobin (HbA1c) or fasting blood glucose may be used to test for diabetes in people taking antipsychotic medication.
July 2020: We have linked to the NICE guideline on supporting adult carers in recommendations 184.108.40.206 and 220.127.116.11. We have incorporated footnote text into the recommendations to meet accessibility requirements.
August 2019: Text has been added to recommendation 18.104.22.168 to indicate that the advice has not changed after our review of the 2019 STEPWISE trial. The recommendation label has been changed to  to indicate that the evidence was last reviewed in 2019. Links have been updated.
