Further information
Fluoxetine belongs to a group of medicines called antidepressants. It is used to treat the following conditions:

major depressive episodes

bulimia nervosa

obsessive compulsive disorder
Children and adolescents aged 8 years and above:

moderate to severe major depressive disorder, if the depression does not respond to psychological therapy after 4-6 sessions. Fluoxetine should be
offered to a child or young person with moderate to severe major depressive disorder only in combination with psychological therapy.
Do not take Fluoxetine if you

are allergic (hypersensitive) to fluoxetine or any of the other ingredients of Fluoxetine (see Section 6 and end of Section 2).

are taking metoprolol which is used to treat cardiac failure.

are already taking monoamine oxidase inhibitors (MAOIs) or you have finished taking a course of them in the last two weeks. Examples of such MAOIs
include medicines used to treat depression such as nialamide, iproniazide, modobemide, phenelzine, tranylcypromine, isocarboxacid, toloxatone and
also linezolid (an antibiotic).
Treatment with fluoxetine should only be started at least 2 weeks after dicontinuation of an irreversible non-selective MAOI. However, treatment with fluoxetine can
be started the following day after discontinuation of certain reversible MAOIs for e.g. moclobemide, linezolid, methylthioninium (methylene blue). Do not take
MAOI for at least 5 weeks after you stop taking fluoxetine.
Take special care with Fluoxetine and tell your doctor if you have:

ever had suicidal thoughts or want to harm yourself. Depression is associated with an increased risk of suicidal thoughts, self harm and suicide. The
risk persists until your condition improves. Since it can take 3-4 weeks before your illness improves following treatment with Fluoxetine, your doctor
will want to monitor you closely at the start of treatment, or if your dose is changed.

If you have fits (seizures) or experience an increase in seizure frequency, contact your doctor immediately; fluoxetine might need to be discontinued.

liver or kidney problems. A low dose of Fluoxetine may be appropriate for you.

diabetes, as your dose may need to be adjusted, as Fluoxetine contains sucrose.

ever had mania or its mild form (hypomania).

heart problems.

low resting heart-rate and/or if you know that you may have salt deletion as a result of prolonged diarrhoea or vomiting, or use of diuretics.

bleeding or blood clotting problems which may be controlled by medicine.

are taking medicines that thin the blood.

begun to experience fever, muscle stiffness or tremor, changes in your mental state like confusion, irritability and extreme agitation; you may suffer
from the so-called “serotonin syndrome” or “neuroleptic malignant syndrome”. Although this syndrome occurs rarely, it may result in potentially life
threatening conditions: contact your doctor immediately, Fluoxetine might need to be discontinued.

a rare hereditary fructose intolerance, glucose-galactose malabsorption or sucrase-isomaltase insufficiency.

alcoholism. You must not consume alcohol while taking Fluoxetine.

are undergoing ECT (electro-convulsive therapy);

Use in children and adolescents aged 8 to 18 years:
Patients under 18 have an increased risk of side-effects such as suicide attempt, suicidal thoughts and hostility (predominantly aggression, oppositional
behaviour and anger) when they take this class of medicines. Fluoxetine should only be used in children and adolescents aged 8 to 18 years for the treatment
of moderate to severe major depressive episodes (in combination with psychological therapy) and it should not be used to treat other conditions.
Fluoxetine should not be used in the treatment of children under the age of 8 years.
Taking other medicines

Fluoxetine may affect the way some medicines work, especially the following:

monoamine oxidase inhibitors (MAOIs) which are used to treat depression. Irreversible nonselective MAOIs must not be used with fluoxetine as serious
fatal reactions (serotonin syndrome) can occur (see section Do not take fluoxetine). Some MAOIs type A for example moclobemide, linezolid,
methylthioninium chloride (methylene blue) type B (selegeline) can be used with fluoxetine provided that your doctor monitors you closely.

metoprolol (which is used to treat heart problems).

tamoxifen (which is used to treat breast cancer).


mequitazine (which is used to treat allergies and rhinitis).

phenytoin (for epilepsy).

medicines that increase the level of serotonin such as lithium, tramadol (a painkiller), tripans (for migraine), tryptophan, selegiline or St. Johns Wort.

medicines that may affect the heart’s rhythm e.g. Class IA and III antiarrhythmics, antipsychotics (e.g. phenothiazine derivatives, pimozide, haloperidol),
tricyclic antidepressants, certain antimicrobial agents (e.g. sparfloxacin, moxifloxacin, erythromycin IV, pentamidine,) anti-malaria treatment particularly
halofantrine, certain antihistamines (astemizole).

medicines affecting CYP2D6 enzyme such as flecainide, propafenone and nebivol (for heart problems), carbamazepine (for epilepsy), tricyclic
antidepressants (for example imipramine, desipramine and antitriptyline) atomoxetine (for attention deficit and hyperactivity disorders) and risperidine
(for some psychiatric disorders).

cyproheptadine (for treating allergic reactions)

warfarin (used to thin your blood)

diuretics (water tablets that help you pass more urine), especially if you are elderly

‘atypical antipsychotics’ (like clozapine, phenothiazines)

Fluoxetine can be used during pregnancy but caution should be exercised, especially during late pregnancy or just prior to the onset of labour.

continued, your doctor may prescribe a lower dose of Fluoxetine.
Fluoxetine has been shown to reduce the quality of sperm in animal studies. Theoretically, this could affect fertility, but impact on human fertility has not been
observed as yet.

If you take more Fluoxetine than you should
If you have taken more Fluoxetine than you should, contact your doctor, pharmacist or nearest hospital casualty department immediately. Symptoms of overdose
include nausea, vomiting, fits, heart problems (including irregular heart beat and cardiac arrest) lung problems and change in mental condition ranging from
agitation to coma.
If you forget to take Fluoxetine
If you miss a dose, DO NOT take a double dose to make up for the forgotten dose, just take your next dose of Fluoxetine at your next dosage time.
If you stop taking Fluoxetine
If you are prescribed other medicines within 5 weeks of stopping your treatment, tell your doctor or pharmacist that you have been taking Fluoxetine.
Common withdrawal symptoms are: dizziness, headache, pins and needles, anxiety, feeling sick, sleep disturbances, feeling restless or agitated, unusual
tiredness or weakness and tremors (shakiness).
If you have any further questions on the use of this product, ask your doctor or pharmacist.
Like all medicines, Fluoxetine can cause side effects, although not everybody gets them.
Cases of suicidal ideation and suicidal behaviours have been reported during Fluoxetine therapy or early after treatment discontinuation.
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
