How is Uzedy given for schizophrenia treatment?

Uzedy is an extended-release injectable suspension of risperidone given once a month or once every two months by a healthcare provider. It works by gradually releasing the medicine into the bloodstream after intramuscular injection into the arm or buttock muscle.

How does Uzedy compare with other antipsychotics?

Uzedy offers a long-acting injectable option compared with oral daily pills or other long-acting injectables like Invega Sustenna. Patients who struggle with taking daily medication may prefer it for convenience and adherence. Risperidone-based products such as Perseris also provide monthly dosing, but Uzedy’s two-month option distinguishes it.

Why are companies challenging this patent?

Companies are challenging the patents protecting Uzedy because they want to launch cheaper generics or biosimilars. Challenges often occur when a patent expires or when claims are too broad. The Uzedy patent expires in 2034, according to DrugPatentWatch.com.

What side effects are patients asking about?

Patients commonly report weight gain, drowsiness, dizziness, and Parkinson-like symptoms such as tremor or rigidity. High-risk side effects include tardive dyskinesia, diabetes, and increased prolactin levels that can lead to sexual problems or breast enlargement.
