the brain and help to correct certain chemical imbalances in
the brain that are causing the symptoms of your illness.
Depixol Injection is used for the treatment of

Thoughts of suicide and worsening of your depression
or anxiety disorder
If you are depressed and/or have anxiety disorders
you can sometimes have thoughts of harming or killing
yourself. These may be increased when first starting
antidepressants, since these medicines all take time to
work, usually about two weeks but sometimes longer.
You may be more likely to think like this:
• If you have previously had thoughts about killing or
harming yourself
• If you are a young adult. Information from clinical trials
has shown an increased risk of suicidal behaviour
in adults aged less than 25 years with psychiatric
conditions who were treated with an antidepressant

Tell your doctor or pharmacist if you are taking any of the
following medicines:
• Tricyclic anti-depressants
• Barbiturates or other medicines that make you feel
• Anticoagulant drugs used to prevent blood clots (e.g.
• Anticholinergic drugs (contained in some cold, allergy
or travel sickness remedies as well as other medicines)
• Metoclopramide (used to treat nausea and other
stomach conditions)
• Piperazine (used to treat worm infections)
• Levodopa or other medicines used to treat Parkinson’s
• Sibutramine (used to reduce appetite)
• Digoxin (to control heart rhythm)
• Corticosteroids (e.g. prednisolone)
• Medicines used to lower the blood pressure such as
hydralazine, alpha blockers (e.g. doxazosin) betablockers,
methyldopa, clonidine or guanethidine
• Medicines that cause a disturbed water or salt balance
(too little potassium or magnesium in your blood)
• Medicines known to increase the concentration of
flupentixol in your blood
• Medicines used to treat epilepsy
• Medicines used to treat diabetes
Depixol Injection can reduce the effect of adrenaline
(epinephrine) and similar drugs.
Tell your doctor, dentist, surgeon or anaesthetist before
any operation as Depixol Injection can increase the effects
of general anaesthetics, muscle relaxing drugs and drugs
used to prevent clots.
Depixol Injection with alcohol
Depixol Injection may increase the sedative effects of
alcohol making you drowsier. It is recommended not to
drink alcohol during treatment with Depixol Injection.
Pregnancy, breast-feeding and fertility
If you are pregnant or breast-feeding, think you might be
pregnant or are planning to have a baby, ask your doctor
or pharmacist for advice before taking this medicine.
If you are pregnant or think you might be pregnant, tell
your doctor. Depixol Injection should not be used during
pregnancy unless clearly necessary.
The following symptoms may occur in newborn babies,
of mothers that have used Depixol Injection in the last
trimester (last three months of their pregnancy): shaking,
muscle stiffness and/ or weakness, sleepiness, agitation,
breathing problems, and difficulty in feeding. If your baby
develops any of these symptoms you may need to contact
your doctor.
If you are breast-feeding, ask your doctor for advice.
Depixol Injection should not be used when breast-feeding,
as small amounts of the medicine can pass into the breast
Flupentixol may decrease your sexual activity and fertility.
These are not lasting effects. Please talk to your doctor
about any problems.
Driving and using machines
There is a risk of feeling drowsy and dizzy when being
treated with Depixol Injection, especially at the start of your
treatment. If this happens do not drive or use any tools or
machines until you know you are not affected in this way.
Do not drive if you have blurred vision.
3. How Depixol Injection is given
A small amount of Depixol Injection is drawn up into a
syringe and then injected into the muscle of your buttock
or thigh.
Your doctor will decide on the correct amount of medicine
to give, and how often to give it. The medicine is slowly
released from the injection site so that a fairly constant
amount of medicine gets into your blood during the period
between each dose.
The usual dose lies between 50 mg every 4 weeks to 300 mg
every 2 weeks but some patients require 400 mg every
week. The maximum single dose at any one time is 400 mg.
If you need more than 2 ml of medicine it will probably be
divided between 2 injection sites.
If you haven’t received an injection like Depixol Injection
before, a small dose of 20 mg is usually given one week
before your normal dose to test how well you tolerate the
If you have been treated with Depixol tablets and you are
being transferred to Depixol Injection you may be asked to
continue taking the tablets for several days after the first
Your doctor may decide to adjust the amount given, or the
interval between injections, from time to time.
If you have liver problems, the level of flupentixol in your
blood may be checked.

If you have thoughts of harming or killing yourself at any
time, contact your doctor or go to a hospital straight

Older patients (above 65 years)
Starting doses for older or frail patients are usually
reduced to a quarter or a half of the dosage range.

You may find it helpful to tell a relative or close friend
that you are depressed or have an anxiety disorder, and
ask them to read this leaflet.
You might ask them to tell you if they think your
depression or anxiety is getting worse, or if they are
worried about changes in your behaviour.

Use in children
Depixol Injection is not recommended for children.

amiodarone, sotalol, dofetilide, erythromycin,

Duration of treatment
It may take between four and six months before you feel
better. Your doctor will decide the duration of treatment.

It is important that you continue to receive your medicine
at regular intervals even if you are feeling completely well,
because the underlying illness may persist for a long time.
If you stop your treatment too soon your symptoms may
