How Often Is UZEDY Given?
UZEDY (risperidone) extended-release injection is administered once monthly, not every two weeks. It's designed for subcutaneous injection with two dosing options: 50 mg or 100 mg every 4 weeks.[1]
Why the Monthly Schedule?
This formulation uses the Steady Sound technology platform, allowing a single monthly dose to maintain steady risperidone levels over 4 weeks. Clinical trials showed it provides consistent exposure comparable to daily oral risperidone, reducing the need for more frequent injections.[1][2]
Dosing Options and Initiation
- Standard dosing: 50 mg or 100 mg monthly after oral risperidone stabilization.
- Loading regimen: Optional higher initial doses (e.g., 100 mg day 1, 100 mg day 29) to reach therapeutic levels faster.
Patients typically start with oral risperidone for 2-4 weeks before switching. Maximum dose is 100 mg/month; no every-two-weeks option exists.[1]
How It Compares to Other Long-Acting Risperidone Injections
| Injection | Frequency | Dose Range |
|-----------|-----------|------------|
| UZEDY | Monthly | 50-100 mg |
| Risperdal Consta | Every 2 weeks | 12.5-50 mg |
| Perseris | Monthly | 90-120 mg |
UZEDY targets patients frustrated with biweekly shots like Risperdal Consta, offering fewer administrations while matching efficacy in schizophrenia symptom control.[2][3]
What If a Dose Is Missed?
Administer as soon as possible, then resume monthly schedule. If delayed over 4 weeks, restart oral risperidone until the next UZEDY dose. No data supports every-two-weeks catch-up dosing.[1]
