Do atypical and typical antipsychotics have similar side effects?

Douglas E. Severance, MD
Family Medicine
Atypical and typical antipsychotic drugs do have side effects. However, they often affect people in different ways. It is difficult to predict what kind of side effects a person might have from taking antipsychotic medications. Common side effects from most antipsychotics include fatigue, dizziness, fast heartbeat, female reproductive issues, and rashes.

The atypical medications are more likely to cause weight gain, which can lead to problems with diabetes and high cholesterol. Conventional, or typical, antipsychotics may cause problems with movement, including stiffness, restlessness, or muscle spasms and tremors. One serious problem that can occur when using typical antipsychotics for a long time is tardive dyskinesia (TD). This movement disorder causes uncontrollable movements, often around the area of the mouth.
