Risperidone (
Risperdal) is one of the
atypical antipsychotics.
Risperidone can potentially cause
tardive dyskinesia[?]. Common side effects include:
nausea,
anxiety, dizziness,
insomnia, low
blood pressure,
muscle-stiffness/pain,
sedation,
tremors, and
weight-gain.
Risperidone is a very strong
dopamine blocker (antagonist) that is to say it inhibits functioning of dopamine
receptors. It reaches peak
plasma levels quickly regardless of whether it is administered as a liquid or pills. The strong dopamine-blocking reaction is known to make
some people feel
nauseous if they do things that normally triggers the dopamine reward, such as
eat a good meal or
have sex. Risperidone is
metabolised fairly quickly so this potential for nauseation subsides usually in two to three hours.
