Risperidone is an atypical (second-generation) antipsychotic medication first approved by the FDA in 1993. Originally sold under the brand name Risperdal by Janssen Pharmaceuticals, it has been widely available as a generic since the early 2000s. In 2023, risperidone was among the top 200 most prescribed medications in the United States, with over 2 million prescriptions.
Risperidone is FDA-approved for three primary conditions: schizophrenia (in adults and adolescents ages 13+), bipolar I disorder with acute manic or mixed episodes (in adults and youth ages 10+), and irritability associated with autism spectrum disorder (in children ages 5–17). Its combination of effectiveness, affordability, and broad availability makes it one of the most prescribed psychiatric medications in the world.
Brand names for risperidone products include Risperdal, Risperdal Consta (long-acting injectable), Risperdal M-Tab (orally disintegrating tablets), Perseris, Uzedy, Rykindo, and Risvan. The generic oral tablet is the most commonly dispensed form and is widely available at most pharmacies.

Risperidone works by blocking two types of receptors in the brain: dopamine D2 receptors and serotonin 5-HT2A receptors. This dual mechanism is what makes it an 'atypical' antipsychotic, distinguishing it from older first-generation medications like haloperidol that primarily targeted dopamine alone.
Dopamine D2 blockade: Excess dopamine activity in certain brain pathways is thought to drive hallucinations, delusions, and disorganized thinking in schizophrenia. By blocking D2 receptors — the primary target for dopamine — risperidone reduces these psychotic symptoms.
Serotonin 5-HT2A blockade: Simultaneously blocking serotonin receptors helps offset some of the movement-related side effects that pure dopamine blockers cause, and may contribute to improvements in mood and negative symptoms. Risperidone is metabolized in the liver by CYP2D6 into its active metabolite, 9-hydroxyrisperidone (paliperidone), which has similar antipsychotic activity.

Injected every 2 weeks; requires 3-week oral overlap at initiation

Monthly/bi-monthly — subcutaneous injection (Uzedy)
Extended-release subcutaneous injection; monthly or every 2 months
Generic oral risperidone tablets are not on the FDA's official drug shortage list in 2026. Multiple generic manufacturers produce it, providing supply redundancy that helps keep the medication reliably available. Most major pharmacy chains — CVS, Walgreens, Walmart, Costco — regularly stock the 0.5 mg, 1 mg, and 2 mg tablet strengths.
However, less common tablet strengths (0.25 mg, 3 mg) and specialized formulations like the orally disintegrating tablet (ODT) may not be stocked consistently at every pharmacy. Long-acting injectable forms are specialty products managed through clinic supply or specialty pharmacies. Individual pharmacies can run out of specific strengths due to local demand spikes, wholesaler delays, or lean inventory practices.
If you're having trouble locating your risperidone at a local pharmacy, medfinder can help. medfinder's team calls pharmacies near you to check which ones can fill your prescription, and texts you results — eliminating hours of hold time.
Risperidone is not a controlled substance, which means any licensed prescriber with prescribing authority can write for it — there are no DEA special registration requirements and no mandated in-person visit restrictions. This makes it broadly accessible across healthcare settings.
Because risperidone is not a controlled substance, it can be prescribed via telehealth platforms without the in-person visit requirements that apply to Schedule II medications. Platforms including Teladoc, MDLive, Talkiatry, and Cerebral can prescribe risperidone for appropriate patients. This makes risperidone accessible in underserved rural areas with limited psychiatric coverage.
No. Risperidone is not a controlled substance under the DEA's Controlled Substances Act. It is not classified under any schedule (I–V). This has important practical implications for patients:
The following side effects are commonly reported and usually manageable:

Risperidone is a well-established, widely used atypical antipsychotic with over 30 years of clinical use. It is FDA-approved for schizophrenia, bipolar I disorder, and autism-related irritability, and is available in multiple formulations including oral tablets, disintegrating tablets, oral solution, and several long-acting injectables. As a widely available generic, it is one of the most affordable psychiatric medications when discount programs are used properly.
While risperidone is generally available in 2026 without a national FDA shortage, individual pharmacies can run out of specific strengths. Never stop risperidone abruptly — always contact your prescriber if you have difficulty filling your prescription. With proper planning, including refilling 5–7 days early and using mail-order for 90-day supplies, most patients can maintain continuous therapy without interruption.
If you're struggling to find risperidone at a pharmacy near you, medfinder is built to solve exactly this problem. Provide your medication details and location, and medfinder's team will call pharmacies near you and text you which ones can fill your prescription — saving you hours of frustrating hold queues.
