1. What Depixol Conc. Injection is and what it is used for

The name of your medicine is Depixol Conc. 100 mg/ml solution for injection (called Depixol Conc. Injection in this leaflet).

Depixol Conc. Injection contains the active substance flupentixol decanoate. Depixol Conc. Injection belongs to a group of medicines known as antipsychotics (also called neuroleptics). These medicines act on nerve pathways in specific areas of the brain and help to correct certain chemical imbalances in the brain that are causing the symptoms of your illness.

Depixol Conc. Injection is used for the treatment of schizophrenia and other psychoses.

Your doctor, however, may prescribe Depixol Conc. Injection for another purpose. Ask your doctor if you have any questions about why Depixol Conc. Injection has been prescribed for you.

2. What you need to know before Depixol Conc. Injection is given

Depixol Conc. Injection is not given if you

  • are allergic (hypersensitive) to flupentixol, other thioxanthene drugs or antipsychotic drugs or any of the other ingredients of this medicine (listed in section 6).
  • are feeling less alert than usual, or are drowsy or sleepy, or have serious problems with your blood circulation
  • are excited or agitated

Warnings and precautions

Talk to your doctor, pharmacist or nurse before Depixol Conc. Injection is given if you:

  • have a heart condition, including an irregular heart beat (such as a slower heart beat); have had a recent heart attack or have problems that cause ankle swelling or shortness of breath
  • have severe breathing problems (such as asthma or bronchitis)
  • have liver, kidney or thyroid problems
  • Suffer from epilepsy, or have been told that you are at risk of having fits (for example because of a brain injury or because of alcohol withdrawal)
  • suffer from Parkinson’s disease, or myasthenia gravis (a condition causing severe muscular weakness)
  • have an enlarged prostate or suffer from a condition known as phaeochromocytoma (a rare type of cancer of a gland near the kidney)
  • suffer from glaucoma (raised pressure within the eye)
  • have risk factors for stroke (e.g. smoking, hypertension)
  • have too little potassium or magnesium in your blood or a family history of irregular heart beats
  • use other antipsychotic medicines
  • suffer from diabetes
  • or someone else in your family has a history of blood clots, as medicines like these have been associated with formation of blood clots
  • are treated for cancer

Children and adolescents

Depixol Conc. Injection is not recommended in these patients.

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

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

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.

Depixol Conc. Injection with alcohol

Depixol Conc. Injection may increase the sedative effects of alcohol making you drowsier. It is recommended not to drink alcohol during treatment with Depixol Conc. 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 for advice before taking this medicine.


If you are pregnant or think you might be pregnant, tell your doctor. Depixol Conc. Injection should not be used during pregnancy unless clearly necessary.

The following symptoms may occur in newborn babies, of mothers that have used Depixol Conc. 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 Conc. Injection should not be used when breastfeeding, as small amounts of the medicine can pass into the breast milk.


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 Conc. 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 Conc. Injection is given

A small amount of Depixol Conc. 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 Conc. Injection before, a small dose of 20 mg is usually given one week before your normal dose to test how well you tolerate the medicine.

If you have been treated with Depixol tablets and you are being transferred to Depixol Conc. Injection you may be asked to continue taking the tablets for several days after the injection.

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.

Older patients (above 65 years)

Starting doses for older or frail patients are usually reduced to a quarter and a half of the dosage range.

Use in children

Depixol Conc. Injection is not recommended for children.

Duration of treatment

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

If you feel that the effect of Depixol Conc. Injection is too strong or weak, talk to your doctor or pharmacist.

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 return.

If you get more Depixol Conc. Injection than you should

Your medicine will be given by your doctor or nurse.

In the unlikely event that you receive too much Depixol Conc. Injection you may experience some symptoms.

Symptoms of overdose may include:

  • Drowsiness
  • Unconsciousness
  • Muscle movements or stiffness
  • Fits
  • Low blood pressure, weak pulse, fast heart rate, pale skin, restlessness
  • High or low body temperature
  • Changes in heart beat including irregular heart beat or slow heart rate

You will receive treatment for any of these symptoms from your doctor or nurse.
