Uzedy

Generic name: Risperidone (injection)
Drug class: Atypical antipsychotics

Usage of Uzedy

Uzedy injection is an extended-release injectable suspension used in adults to treat schizophrenia (a mental illness that causes disturbed or unusual thinking, loss of interest in life, and strong or inappropriate emotions).

Uzedy belongs to a class of medications called atypical antipsychotics. Risperidone works by changing the activity of certain natural substances in the brain.
