How does haloperidol work?
Haloperidol blocks dopamine receptors in the brain, which helps reduce symptoms of psychosis, agitation, and severe behavioural disturbances.
What is haloperidol used to treat?
Haloperidol is commonly prescribed for:
- Schizophrenia and psychosis (to reduce hallucinations and delusions)
- Acute agitation and aggression (in conditions like bipolar disorder or dementia)
- Tourette’s syndrome and severe tics
- Huntington’s disease (to control movement disorders)
- Severe nausea and vomiting (in some cases)
Who can take haloperidol?
Haloperidol is suitable for most adults and some children, depending on the condition being treated.
Who might not be able to take haloperidol?
Haloperidol may not be suitable if you:

Can I take haloperidol if I’m pregnant or breastfeeding?
Haloperidol may be used during pregnancy or breastfeeding if the benefits outweigh the risks, but speak to your doctor before taking it.
What if I miss a dose?
If you forget a dose, take it as soon as you remember. If it’s close to your next dose, skip the missed one—do not take two doses at once.
How effective is haloperidol?
Haloperidol is highly effective at reducing psychotic symptoms and controlling agitation when taken as prescribed.
What should I do if I take too much?
Taking too much haloperidol can cause severe drowsiness, muscle stiffness, tremors, or breathing problems. If you think you’ve taken too much, seek emergency medical help immediately.

- For acute agitation: 5mg as needed, up to every 4 to 8 hours
- For Tourette’s syndrome: 0.5mg to 3mg daily
