Perseris (risperidone extended-release injectable suspension) has a wholesale acquisition cost (WAC) of about $3,500 to $4,000 per 90 mg or 120 mg monthly dose, depending on the pharmacy and exact formulation. Patient out-of-pocket costs vary widely based on insurance—often $0 to $1,000 monthly with coverage, or higher without.[1]
Most commercial plans cover Perseris, but copays range from $30 to $500 per dose. Medicare Part D patients may pay $100–$300 after deductibles. Indivior's patient assistance program caps costs at $10/month for eligible uninsured or underinsured patients earning under $50,000/year.[2]
The long-acting injectable form requires specialized manufacturing and administration, driving up the price compared to generic oral risperidone ($10–$50/month). It's positioned for non-adherent schizophrenia patients, justifying the premium to payers.[1][3]
