Sedation (drowsiness) is a common side-effect of antipsychotics. The antipsychotics that cause the most sedation include
chlorpromazine, promazine, thioridazine, clozapine and zotepine. Often this can be dealt with by taking your medication at night just before you go to bed. If feeling sedated is a problem for you, contact your doctor as they may be able to reduce the dose or change your medication.

Movement disorders
Movement disorders are very common with the typical antipsychotics. There are different types of movement disorder. These include:
Dystonia - prolonged muscle spasms often involving the face, neck, shoulders and upper limbs. Drugs such as procyclidine and orphenadrine are given to treat dystonia.
Akathisia - fidgety movements of the legs which may be accompanied by a strong sense of inner restlessness and unease. This often means that a person cannot sit comfortably, and may be driven to walk up and down to try and gain relief. It is best treated with clonazepam or propranolol.
