Yes, the term "schizo" can be considered a slur. It is a slang abbreviation of “schizophrenic” which is an outdated term for the mental illness schizophrenia. 

It is important not to use “schizo” or “schizophrenic" when referring to someone because it can reinforce harmful stereotypes and stigma around a serious condition.

Why "schizo” is offensive

Using “schizo” or “schizophrenic” to describe someone labels them solely by their condition. This approach is disrespectful and can be isolating. It reduces a person to a diagnosis, rather than recognising them as an individual.

The impact of language 

Language shapes how we see people. When we use labels like “schizo” or "schizophrenic," we risk reinforcing negative stereotypes and increasing stigma. This can make life harder for people living with schizophrenia, affecting their confidence and sense of belonging. 

What to say instead of “schizo” 

Rethink Mental Illness recommends using people-first language. Instead of “schizo” or "schizophrenic," say: 

• Someone living with schizophrenia 
• A person affected by schizophrenia 

This puts the person before the condition, helping to create a more inclusive and supportive environment.
