Indications
Orap is a prescription medication primarily used to treat motor and vocal tics associated with Tourette's syndrome in adults and children. It contains the active ingredient pimozide. Pimozide belongs to a class of medications called antipsychotics. It works by blocking the transmission of dopamine and other neurotransmitters in the brain, which helps to reduce the severity and frequency of tics in people with Tourette's syndrome.
Orap may be used alone or with other medications. It should not be used for mild symptoms. It should only be used if symptoms cause severe problems in everyday life and other medicines or treatments have not been effective. It is not known if Orap is safe and effective in children younger than 2 years of age.
