1. WHAT HALOPERIDOL INJECTION IS AND WHAT IT IS
USED FOR
Haloperidol Injection contains the active substance haloperidol.
This belongs to a group of medicines called ‘antipsychotics’.
Haloperidol Injection is used in adults 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 excited, agitated, enthusiastic, impulsive or
hyperactive
• Feel very aggressive, hostile or violent.
Haloperidol Injection is also used in adults:
• To help control movements in Huntington’s disease
• To prevent or treat nausea and vomiting (feeling and being
sick) after surgery.
Haloperidol Injection may be used on its own or with other
medicine, and is sometimes used when other medicines or
treatments have not worked, caused unacceptable side effects,
or cannot be taken by mouth.
2. WHAT YOU NEED TO KNOW BEFORE YOU ARE GIVEN
HALOPERIDOL INJECTION

• You are allergic to haloperidol or any of the other ingredients
of this medicine (listed in section 6)
• You are less aware of things around you or your reactions
become unusually slow
• You have Parkinson’s disease
• You have a type of dementia called ‘Lewy body dementia’
• You have progressive supranuclear palsy (PSP)
• You have a heart condition called ‘prolonged QT interval’, or
any other problem with your heart rhythm that shows as an
abnormal tracing on an ECG (electrocardiogram)
• You have heart failure or recently had a heart attack
• You have a low level of potassium in your blood, which has
not been treated
• You take any of the medicines listed under ‘Other medicines
and Haloperidol – Do not use Haloperidol injection if you are

This medicine must not be used if any of the above applies to
you. If you are not sure, talk to your doctor, pharmacist or nurse
before being given haloperidol injection.
Warnings and precautions
Serious side effects
Haloperidol injection 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 using Haloperidol
injection 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 before being given Haloperidol
injection if you are elderly, particularly if you have dementia.
Talk to your doctor if you have:
• A slow heart beat, 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 injection you are given may have to be altered.
If you are not sure if any of the above applies to you, talk to
your doctor or nurse before you are given Haloperidol injection.
Medical check ups
Your doctor may want to take an electrocardiogram (ECG)
before or during your treatment with Haloperidol Injection. The
ECG measures the electrical activity of your heart.
Blood tests
Your doctor may want to check the levels of potassium or
magnesium (or other electrolytes) in your blood before or
during your treatment with Haloperidol injection.
Children and adolescents
Haloperidol Injection should not be used in children and
adolescents below 18 years. This is because it has not been
studied in these age groups.
Other medicines and Haloperidol Injection
Tell your doctor or nurse if you are taking or have recently taken
or might take any other medicines.
Do not use Haloperidol injection if you are taking certain
medicines for:
• Problems with your heart beat (such as amiodarone,
dofetilide, disopyramide, dronedarone, ibutilide, quinidine
and sotalol)
• Depression (such as citalopram and escitalopram)
• Psychoses (such as fluphenazine, levomepromazine,
perphenazine, pimozide, prochlorperazine, promazine,
sertindole, thiorizadine, trifluoperazine, triflupromazine and
ziprasidone)
• Bacterial infections (such as azithromycin, clarithromycin,
erythromycin, levofloxacin, moxifloxacin and telithromycin)

8899/98765432/0000

• Fungal infections (such as pentamidine)
• Malaria (such as halofantrine)
• Nausea and vomiting (such as dolasetron)
• Cancer (such as toremifene and vandetanib).
Also tell your doctor if you are taking bepridil (for chest pain or
to lower blood pressure) or methadone (a pain killer or to treat
drug addiction).
These medicines may make heart problems more likely, so talk
to your doctor if you are taking any of these and do not use
Haloperidol Injection (see ‘Do not use Haloperidol Injection if’).
Special monitoring may be needed if you are using lithium
and Haloperidol injection at the same time.
Tell your doctor straight away and stop taking both medicines if
you get:
• Fever you can’t explain or movements you can’t control
• Confused, disoriented, a headache, balance problems and
feel sleepy
These are signs of a serious condition.
Certain medicines may affect the way that Haloperidol
injection works or may make heart problems more likely
Tell your doctor if you are taking:
• Alprazolam or buspirone (for anxiety)
• Duloxetine, fluoxetine, fluvoxamine, nefazodone, paroxetine,
sertraline, St John’s Wort (Hypericum, perforatum) or
venlafaxine (for depression)
• Bupropion (for depression or to help you stop smoking)
• Carbamazepine, phenobarbital or phenytoin (for epilepsy)
• Rifampicin (for bacterial infections)
• Itraconazole, posaconazole or voriconazole (for fungal
infections)
• Ketoconazole tablets (to treat Cushing’s syndrome)
• Indinavir, ritonavir or saquinavir (for human
immunodeficiency virus or HIV)
• Chlorpromazine or promethazine (for nausea and vomiting)
• Verapamil (for blood pressure or heart problems).
Also tell your doctor if you are taking any other medicines to
lower blood pressure, such as water tablets (diuretics).
Your doctor may have to change your dose of Haloperidol
Injection if you are taking any of these medicines.
Haloperidol injection can affect the way the following types
of medicine work
Tell your doctor if you are taking medicines for:
• Calming you down or helping you to sleep (tranquillisers)
• Pain (strong pain killers)
• Depression (‘tricyclic antidepressants’)
• Lowering blood pressure (such as guanethidine and
methyldopa)
• Severe allergic reactions (adrenaline)
• Attention deficit hyperactivity disorder (ADHD) or narcolepsy
(known as ‘stimulants’)
• Parkinson’s disease (such as levodopa)
• Thinning the blood (phenindione).
Talk to your doctor or nurse before being given Haloperidol
Injection if you are taking any of these medicines.
Haloperidol Injection with alcohol
Drinking alcohol while you are using Haloperidol Injection might
make you feel sleepy and less alert. This means you should be
careful how much alcohol you drink. Talk to your doctor about
drinking alcohol while using Haloperidol Injection, and let your
doctor know how much you drink.
Pregnancy, breast-feeding and fertility
Pregnancy – if you are pregnant, think you may be pregnant or
are planning to have a baby, ask your doctor for advice. Your
doctor may advise you not to use Haloperidol Injection while
you are pregnant.
The following problems may occur in newborn babies of
mothers that use Haloperidol Injection in the last 3 months of
their pregnancy (the last trimester):
• Muscle tremors, stiff or weak muscles
• Being sleepy or agitated
• Problems breathing or feeding.
The exact frequency of these problems is unknown. If you used
Haloperidol Injection while pregnant and your baby develops
any of these side effects, contact your doctor.
Breast-feeding – talk to your doctor if you are breast-feeding or
planning to breast-feed. This is because small amounts of the
medicine may pass into the mother’s milk and on to the baby.
Your doctor will discuss the risks and benefits of breast-feeding
while you are using Haloperidol Injection.
Fertility – Haloperidol Injection may increase your levels of a
hormone called ‘prolactin’, which may affect fertility in men and
women. Talk to your doctor if you have any questions about
this.
Driving and using machines
Haloperidol Injection can affect your ability to drive and use
tools or machines. Side effects, such as feeling sleepy, may
affect your alertness, particularly when you first start using it or
after a high dose. Do not drive or use any tools or machines
without discussing this with your doctor first.
Haloperidol Injection contains sodium
This medicine contains less than 1 mmol sodium (23mg) per
dose, i.e. is essentially sodium free.
3. HOW TO USE HALOPERIDOL INJECTION
Always use this medicine exactly as your doctor has told you.
Check with your doctor or pharmacist if you are not sure.
How much medicine will be given to you
Your doctor will decide how much Haloperidol Injection you
need and for how long. It may be some time before you feel the
full effect of the medicine. Your doctor will normally give you a
low dose to start, and then adjust the dose to suit you. Your
dose of haloperidol will depend on:
• Your age
• What condition you are being treated for
• Whether you have problems with your kidneys or liver
• Other medicines you are taking.
Adults:
• Your starting dose will normally be between 1 and 5 mg.
• You may be given extra doses, normally 1 to 4 hours apart.
• You will not be given more than a total of 20 mg each day.
Elderly people
• Elderly people will normally start on half the lowest adult
dose.
• The dose will then be adjusted until the doctor finds the
dose that suits you best.
• You will not be given more than a total of 5 mg each day
unless your doctor decides a higher dose is needed.
How Haloperidol Injection is given
Haloperidol Injection will be given by a doctor or nurse. It is for
intramuscular use, and is given as an injection into a muscle.
If you stop using Haloperidol Injection
Unless your doctor decides otherwise, Haloperidol Injection will
be stopped gradually. Stopping treatment suddenly may cause
effects such as:
• Nausea and vomiting
• Difficulty sleeping.
Always follow your doctor’s instructions carefully.
If you miss a dose or have too much Haloperidol Injection
A doctor or nurse will give this medicine to you, so it is unlikely
that you will miss a dose or be given too much. If you are
worried, tell the doctor or nurse.
