How much risperidone is safe?

The safe and effective dose of risperidone can vary depending on several factors, including the individual’s age, weight, medical history, and the condition being treated. It is important to follow the dosing instructions provided by a healthcare provider and to never exceed the prescribed dose.

The typical starting dose of risperidone for the treatment of schizophrenia is 1-2 milligrams per day, while the typical starting dose for bipolar disorder is 2-3 milligrams per day. The dose may be gradually increased over time if necessary, with the maximum recommended dose being 8 milligrams per day for schizophrenia and 6 milligrams per day for bipolar disorder.

For the treatment of irritability associated with autism spectrum disorder, the starting dose is typically lower, with a maximum dose of 3 milligrams per day.

It is important to note that risperidone can cause side effects, some of which may be significant. Anyone taking risperidone should be monitored closely by a healthcare provider for potential side effects, including movement disorders, metabolic changes, and cardiovascular effects.

Ultimately, the safe and effective dose of risperidone will depend on the individual and their specific medical history and condition. Anyone with questions or concerns about the appropriate dose of risperidone should speak with their healthcare provider.


There are various forms of drugs available, such as tablets or liquids, and each may have a separate patient information leaflet (PIL) for different doses. It is important to refer to the PIL for the specific form and dose of the drug that you have been prescribed.
