Risperidone: what it is for, how to take it and side effects


Risperidone is an antipsychotic drug indicated for the treatment of psychotic disorders, such as schizophrenia, with symptoms such as hallucinations, delusions, distrust, social isolation, anxiety or hearing voices. This is because this remedy works by promoting the balance of substances in the brain, such as dopamine and serotonin, improving communication between neurons.

This medicine can be found in pharmacies or drugstores in the form of tablets or oral solution, in its generic form or under the trade names Zargus, Perlid, Risperidon or Viverdal, for example.
