Uzedy (risperidone): Uses, Side Effects, Safety & What to Know

Uzedy (risperidone) is a long-acting injectable medication used to treat schizophrenia and bipolar disorder in adults. It helps manage symptoms such as hallucinations, delusions, disorganized thinking, mood instability, and manic symptoms by providing consistent medication levels over time.

Both contain risperidone, but Uzedy is a long-acting injection given on a scheduled basis, while oral risperidone is taken daily. Uzedy can help reduce missed doses and improve consistency.

Uzedy affects dopamine and serotonin pathways in the brain, which can help reduce symptoms such as hallucinations, delusions, disorganized thinking, and mood or behavioral instability.

Some people notice improvement in symptoms within the first 1–2 weeks, but full stabilization often takes several weeks. Response depends on symptom severity and treatment history.

Uzedy is administered as a scheduled subcutaneous injection at regular intervals. Your provider will determine the exact dosing schedule based on your clinical needs.

Common side effects may include:

• Drowsiness or fatigue

• Weight gain or appetite changes

• Restlessness

• Digestive upset

• Injection-site reactions
