1. WHAT HALOPERIDOL IS AND WHAT IT IS USED FOR
The name of your medicine is Haloperidol Oral Solution BP 10 mg/5 ml (“Haloperidol”).
Haloperidol contains the active substance haloperidol. This belongs to a group of medicines called ‘antipsychotics’.
Haloperidol is used in adults, adolescents and children for illnesses affecting the way you think, feel or behave. These include mental
health problems (such as schizophrenia and bipolar disorder) and behavioural problems.
These illnesses may make you:
• feel confused (delirium)
• see, hear, feel or smell things that are not there (hallucinations)
• believe things that are not true (delusions)
• feel unusually suspicious (paranoia)
• feel very aggressive, hostile or violent
• feel very excited, agitated, enthusiastic, impulsive or hyperactive.
In adolescents and children, Haloperidol is used to treat schizophrenia in patients aged 13 to 17 years, and to treat behavioural
problems in patients aged 6 to 17 years.
Haloperidol is also used:
• in adolescents and children aged 10 to 17 years and in adults for movements or sounds you can’t control (tics), for example in
severe Tourette’s syndrome
• in adults to help control movements in Huntington’s disease.
Haloperidol is sometimes used when other medicines or treatments have not worked or caused unacceptable side effects.
2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE HALOPERIDOL
Do NOT take Haloperidol:
• if you are allergic to haloperidol or any of the other ingredients of this medicine (listed in section 6).
• if you are less aware of things around you or your reactions become unusually slow
• if you have Parkinson’s disease
• if you have a type of dementia called ‘Lewy body dementia’
• if you have progressive supranuclear palsy (PSP)
• if you have a heart condition called ‘prolonged QT interval’, or any other problems with your heart rhythm that shows as an abnormal
tracing on an ECG (electrocardiogram)
• if you have heart failure or recently had a heart attack
• if you have a low level of potassium in your blood, which has not been treated
• if you take any of the medicines listed under ‘Other medicines and Haloperidol – Do not take Haloperidol if you are taking certain
Do not take this medicine if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking Haloperidol.
Warnings and precautions
Serious side effects
Haloperidol can cause problems with the heart, problems controlling body or limb movements and a serious side effect called
‘neuroleptic malignant syndrome’. It can also cause severe allergic reactions and blood clots. You must be aware of serious side effects
while you are taking Haloperidol because you may need urgent medical treatment. See ‘Look out for serious side effects’ in section 4.
Elderly people and people with dementia
A small increase in deaths and strokes has been reported for elderly people with dementia who are taking antipsychotic medicines.
Talk to your doctor or pharmacist before taking Haloperidol if you are elderly, particularly if you have dementia.
Talk to your doctor or pharmacist if you have:
• a slow heartbeat, heart disease or anyone in your close family has died suddenly of heart problems
• low blood pressure, or feel dizzy upon sitting up or standing up
• a low level of potassium or magnesium (or other ‘electrolyte’) in your blood. Your doctor will decide how to treat this
• ever had bleeding in the brain, or your doctor has told you that you are more likely than other people to have a stroke
• epilepsy or have ever had fits (convulsions)
• problems with your kidneys, liver or thyroid gland
• a high level of the hormone ‘prolactin’ in your blood, or cancer that may be caused by high prolactin levels (such as breast cancer)
• a history of blood clots, or someone else in your family has a history of blood clots
• depression, or you have bipolar disorder and start to feel depressed.
You may need to be more closely monitored, and the amount of Haloperidol you take may have to be altered.
If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before taking Haloperidol.
Medical check ups
Your doctor may want to take an electrocardiogram (ECG) before or during your treatment with Haloperidol. The ECG measures the
electrical activity of your heart.
Your doctor may want to check the levels of potassium and magnesium (or other ‘electrolyte’) in your blood before or during your
treatment with Haloperidol.
Children below 6 years of age
Haloperidol should not be used in children below 6 years of age. This is because it has not been studied adequately in this age group.
