What this medicine is used for

The name of your medicine is Fluoxetine. It contains the active ingredient fluoxetine (as fluoxetine hydrochloride).
Fluoxetine belongs to a group of medicines called selective serotonin reuptake inhibitors (SSRIs). Serotonin is one of the chemicals in your brain which helps control your mood. Fluoxetine and other SSRIs are thought to help by increasing the amount of serotonin in your brain.
Fluoxetine is used to treat:
depression
obsessive compulsive disorder (OCD)
premenstrual dysphoric disorder (PDD)
Depression is longer lasting and/or more severe than the 'low moods' everyone has from time to time due to the stress of everyday life. It is thought to be caused by a chemical imbalance in parts of the brain. This imbalance affects your whole body and can cause emotional and physical symptoms such as feeling low in spirit, loss of interest in activities, being unable to enjoy life, poor appetite or overeating, disturbed sleep, often waking up early, loss of sex drive, lack of energy and feeling guilty over nothing. Fluoxetine corrects this chemical imbalance and may help relieve the symptoms of depression.
Check with your doctor if you need more information about obsessive compulsive disorder (OCD).
The symptoms of OCD vary from patient to patient.
This medicine is not expected to affect your ability to drive a car or operate machinery, but make sure you know how it affects you beforehand, as it can make some people dizzy or drowsy, and affect judgement, thinking and motor skills.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed this medicine for another reason.
There is not enough information to recommend the use of this medicine for children under the age of 18 years.

any of the ingredients listed at the end of this leaflet
Some of the symptoms of an allergic reaction may include:
shortness of breath
wheezing or difficulty breathing
swelling of the face, lips, tongue or other parts of the body

Do not take this medicine if you are taking other medicines called Monoamine Oxidase Inhibitors (MAOIs).
These may be used for the treatment of depression (phenelzine, tranylcypromine or moclobemide), Parkinson's disease (selegiline) or infections (linezolid).
Do not take fluoxetine until 14 days after stopping any MAOI, and do not take MAOIs until at least 5 weeks after stopping fluoxetine.
Taking fluoxetine with a MAOI may cause a serious reaction with signs such as a sudden increase in body temperature, very high blood pressure, rigid muscles, nausea, vomiting and/or fits (convulsions).
Do not take this medicine if you are taking pimozide (Orap), a medicine used to treat disturbances in the way people think, feel or act.
Taking pimozide together with fluoxetine may alter the rhythm of your heart.
Do not take this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering.
If it has expired or is damaged, return it to your pharmacist for disposal.

Before you start to take it

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.
Tell your doctor if you are pregnant, or plan to become pregnant.
There have been reports that babies exposed to fluoxetine and other antidepressants during the third trimester of pregnancy may develop complications after birth.
Do not take this medicine whilst pregnant until you and your doctor have discussed the risks and benefits involved.
Tell your doctor if you are breastfeeding, or plan to breastfeed.
Fluoxetine can pass into breast milk. Do not take this medicine whilst breast-feeding until you and your doctor have discussed the risks and benefits involved

If you have not told your doctor about any of the above, tell them before you start taking this medicine.

Taking other medicines

Tell your doctor if you are taking any other medicines, including any that you can get without a prescription from a pharmacy, supermarket or health food shop.
Some combinations of medicines may increase the risk of having serious side effects. These serious side effects may be life-threatening.
In particular, do not take fluoxetine if you are taking the following other medicines:
pimozide, used to treat disorders which affect the way you think, feel or act
monoamine oxidase inhibitors (MAOIs), which are also used for treating depression (phenelzine, tranylcypromine or moclobemide), certain infections (linezolid), and Parkinson's disease (selegiline)
Some other medicines may interact with fluoxetine. These include:
other medicines used to treat depression, obsessive compulsive disorder or premenstrual dysphoric disorder (PMDD), such as sertraline, citalopram, paroxetine and fluvoxamine
medicines used to treat anxiety called benzodiazepines (e.g. diazepam, alprazolam)
medicines called antipsychotics, used to treat certain mental and emotional conditions (e.g. haloperidol and clozapine)
lithium, used to treat mood swings and some types of depression
medicines used to control fits, such as carbamazepine and phenytoin
warfarin, used to thin the blood
sleeping tablets or sedatives
flecainide, used to treat irregular heart beats
tryptophan, contained in some multivitamin and herbal preparations
sumatriptan, and other medicines called triptans used to treat migraines
tramadol, a strong pain-killer
St John's wort (Hypericum perforatum), a herbal remedy
tamoxifen, a medicine for treatment or prevention of breast cancer.
These medicines may be affected by fluoxetine or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.
Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking this medicine.
Do not start taking other medicines for depression without talking to your doctor first. Do this even if you have already stopped taking fluoxetine.
Monoamine oxidase inhibitors (MAOIs), which are other medicines used for depression, may interfere with fluoxetine. You should not start a MAOI for at least 5 weeks after stopping fluoxetine.

How to take this medicine

Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.
If you do not understand the directions, ask your doctor or pharmacist for help.

How much to take

The usual starting dose of fluoxetine is one 20 mg capsule each morning.
Your doctor may increase or decrease this dose depending on how you respond to this medicine.
For premenstrual dysphoric disorder (PMDD), fluoxetine may be prescribed to be taken every day or only during a certain part of the month. Your doctor will prescribe the dosing schedule that is right for you
Do not stop taking your medicine or change your dosage without first checking with your doctor.

How to take it

Swallow the capsule whole with a full glass of water.

When to take it

Fluoxetine is usually taken as a single dose in the morning.
If your doctor tells you to take fluoxetine twice a day, take one dose in the morning and one at midday.
Take your medicine at about the same time each day.
Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
It does not matter if you take this medicine before or after food.

How long to take it for

Continue taking your medicine for as long as your doctor tells you.
For depression, the length of treatment will depend on how quickly your symptoms improve. Most antidepressants take time to work, so don't be discouraged if you don't feel better right away. Some of your symptoms may improve in 1 or 2 weeks but it can take up to 4 to 6 weeks to feel any real improvement.
Even when you feel well, you will usually have to take this medicine for several months or even longer to make sure that the benefits will last.
Occasionally the symptoms of depression or other psychiatric conditions may include thoughts of harming yourself or committing suicide. It is possible that these symptoms may continue or increase until the full anti-depressant effect of your medicine becomes apparent (i.e. one to two months).
You or anyone close to you or caring for you should watch for these symptoms and tell your doctor immediately or go to the nearest hospital if you have any distressing thoughts or experiences during this initial period or at any other time.
Contact your doctor if you experience any worsening of your depression or other symptoms at any time during your treatment.

If you forget to take it

If it is almost time to take your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for the dose that you missed.
This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much of this medicine. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
If you take too much fluoxetine you may be sick or feel sick, agitated, restless, excitable or hyperactive or you may have convulsions (fits).

Keep all your doctor's appointments so that your progress can be checked.
Your doctor may do some tests from time to time to make sure the medicine is working and to prevent unwanted side effects.
Occasionally, the symptoms of depression may include thoughts of suicide or self-harm. It is possible that these symptoms continue or get worse during the first one to two months of taking fluoxetine until the medicine starts to work completely. This is more likely to occur in young adults under 25 years of age (i.e. 18 to 24 years of age) and have not used antidepressant medicines before.
If you or someone you know or care for demonstrates any of the following warning signs of suicide-related behaviour while taking fluoxetine, contact a doctor immediately, or even go to the nearest hospital for treatment:
thoughts or talk of death or suicide
thoughts of talk of self-harm or harm to others
any recent attempts of suicide or self-harm
increase in aggressive behaviour, irritability or agitation or any other unusual changes in behaviour or mood
worsening of depression.
All mentions of suicide or violence must be taken seriously.
Tell your doctor if you get a headache or start to feel dizzy, confused, forgetful, weak, unsteady or unable to concentrate.
Some people (especially older people and/or those taking diuretics/water tablets) may experience a lack of sodium in the blood when taking this medicine. Make sure to drink plenty of fluids.
If you are being treated for depression, be sure to discuss with your doctor any problems you may have and how you feel, especially any feelings of severe sadness, thoughts of suicide, bursts of unusual energy, anger or aggression, or if you become particularly agitated or restless.
This will help your doctor to determine the best treatment for you.

Things you must not do

Do not give your medicine to anyone else, even if they have the same condition as you.

Your doctor may want you to gradually reduce the amount of fluoxetine you are taking before stopping completely.
Do not take the herbal remedy St. John's Wort while you are being treated with fluoxetine.
If you are already taking the herbal remedy, stop taking St. John's Wort and mention it to your doctor at your next visit.

This medicine may make some people dizzy or drowsy, and affect judgement, thinking and motor skills in some people. If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.
Be careful when drinking alcohol while you are taking this medicine.
If you drink alcohol, dizziness or drowsiness may be worse. Your doctor may suggest avoiding alcohol while you are being treated for depression.
If you are diabetic, be sure to regularly monitor your blood glucose levels and tell your doctor if these change significantly.
You should wait at least 5 weeks after stopping fluoxetine before starting any medicines called MAOIs.
