   What Depixol Injection is and what it is used for

   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.

The name of your medicine is Depixol 20 mg/ml solution for injection (called Depixol Injection in this leaflet).

Depixol Injection contains the active substance flupentixol decanoate. Depixol Injection belongs to a group of medicines known as antipsychotics (also called neuroleptics).

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.

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.

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.

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

Pregnancy

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

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

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.

  thioxanthene drugs or antipsychotic drugs or any of the other ingredients of this medicine (listed in section 6)

  hypertension)

  blood or a family history of irregular heart beats

• use other antipsychotic medicines

  Adults

• suffer from diabetes

  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 medicine.

Children and adolescents

Depixol Injection is not recommended in these patients.

Thoughts of suicide and worsening of your depression or anxiety disorder

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 injection.

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.

Your doctor may decide to adjust the amount given, or the interval between injections, from time to time.

You may be more likely to think like this:

• If you have previously had thoughts about killing or

  If you have liver problems, the level of flupentixol in your blood may be checked.

  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

  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.

  Use in children

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

Depixol 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.

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.

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

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.
