paranoia as well as violent or dangerous impulsive behaviour
• aggression, overactivity, and self-mutilation in patients who are
mentally ill and are likely to behave dangerously
• Tourette’s syndrome and tics (repeated and largely involuntary
movements)
• restlessness and agitation in the elderly
• behavioural disorders in children, especially those associated with
hyperactivity and aggression.

• are elderly as you may be more sensitive to the effects of Haloperidol
• are at risk of blood clot in the vein (deep vein thrombosis)
• have or someone else in your family has a history of blood clots, as
medicines like these have been associated with formation of blood
clots

alcohol withdrawal or brain damage

• suffer from dementia
• suffer from depression
• have low blood pressure, calcium or magnesium levels or have not
eaten for a prolonged length of time

any of the above apply to you, talk to your pharmacist before taking
Haloperidol tablets.
Medical check ups

Your doctor may want to check the levels of minerals (electrolytes) in
your blood.
If you suffer from a disorder with related memory loss, you should talk
first to your doctor, who will decide if you can be given Haloperidol and
will explain the possible risks of its use.
