Risperidone vs risperdal?

Short answer: Risperidone is the generic name of the drug. Risperdal is the brand name. They contain the same active ingredient and are used for the same conditions; the difference is mainly branding and formulation options.

Key points:
- Active ingredient: risperidone (same drug, whether you see Risperdal or risperidone on the label).
- Brand vs generic: Generics are usually cheaper and equally effective. Brands may have different packaging or excipients.
- Formulations you might see:
- Oral tablets (generic risperidone or Risperdal tablets)
- Oral solution
- Risperdal M-Tab (orally disintegrating tablet)
- Risperdal Consta (long-acting injectable every 2 weeks)
- Perseris (monthly subcutaneous long-acting injectable)
- Indications (same for brand and generic): schizophrenia, bipolar disorder (manic/mixed episodes), irritability in autism.
- Safety: Same risk profile (weight gain, metabolic changes, increased prolactin, movement disorders, sedation, potential QT considerations, etc.). Elderly with dementia-related psychosis have higher mortality risk with antipsychotics.

If you’re choosing between brand Risperdal and generic risperidone, it’s usually about cost and the specific formulation you need (tablet, liquid, dissolving tablet, or an injectable). Your pharmacist or prescriber can confirm which formulation you should use and whether a switch between brand and generic is appropriate.
