What this medicine is used for

APO-Citalopram contains the active ingredient citalopram (as citalopram hydrobromide).
It is used to treat depression.
Citalopram belongs to a group of antidepressant medicines called Selective Serotonin Reuptake Inhibitors (SSRIs). Citalopram and other SSRIs are thought to help by increasing the amount of serotonin in your brain.
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.
Citalopram corrects this chemical imbalance and may help relieve the symptoms of depression.
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 no evidence that this medicine is addictive.
However, if you suddenly stop taking it, you may get side effects.
This medicine is available only with a doctor’s prescription.
Do not give this medicine to a child or adolescent.
The benefit and safety of citalopram use in children and adolescents below 18 years of age has not been proven.

When you must not take it

Do not take this medicine if you have an allergy to:
any medicine containing citalopram
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

Do not take citalopram until 14 days after stopping most MAOIs. The exception is the MAOI, moclobemide, where you may take citalopram one whole day after finishing taking moclobemide.
Taking citalopram with MAOIs 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). Your doctor will know when it is safe to start citalopram after the MAOI has been stopped.
linezolid, used in some serious bacterial infections

Some other medicines may interact with citalopram. These include:
tryptophan, contained in some multivitamin and herbal preparations
tramadol, a strong pain killer
sumatriptan and similar medicines used to treat migraines and cluster headaches
St John’s Wort (Hypericum perforatum), a herbal remedy
other medicines used to treat depression
lithium, used to treat mood swings and some types of depression
any other medicines used to treat anxiety, obsessive-compulsive disorder or pre-menstrual dysphoric disorder.

If you are taking any of these you may need a different dose or you may need to take different medicines.
If you take medicines which affect the heart rhythm whilst taking citalopram then your doctor will do regular tests on your heart (ECG). Citalopram may also cause changes to your heart rhythm.
Other medicines not listed above may also interact with citalopram.
Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking this medicine.

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

Your doctor or pharmacist will tell you how much of this medicine you should take. This will depend on your condition and whether you are taking any other medicines.
The usual starting dose for adults is 20 mg per day.
Your doctor may increase your dose slowly in stages of 10 mg depending on how you respond to this medicine. The maximum dose is 40 mg a day.
Elderly people have a starting dose of 10 mg per day, which may be increased slowly to a maximum dose of 20 mg a day.
People who take cimetidine or other medicines which affect the blood levels of citalopram (called CYP 2C19 inhibitors), or people who have liver problems should not take more than 20 mg of citalopram per day.
Do not stop taking your medicine or change your dosage without first checking with your doctor.

How to take it

Swallow the tablets whole with a full glass of water. Do not chew them.

When to take it

Take it as a single dose, either in the morning or in the evening, at about the same time each day.
Taking it at the same time each day will have the best effect and will also help you remember when to take it.
It does not matter if you take it before, with or after food.

How long to take it for

Continue taking your medicine for as long as your doctor tells you, even if it takes some time before you feel any improvement in your condition.
Make sure you have enough to last over weekends and holidays.
As with other medicines for the treatment of these conditions, it may take a few weeks before you feel any improvement.
Individuals will vary greatly in their response to this medicine.
Your doctor will check your progress at regular intervals.
The length of treatment may vary for each individual, but is usually at least 6 months.
In some cases your doctor may decide that longer treatment is necessary.
The underlying illness may last for a long time and if you stop your medicine too soon, your symptoms may return.
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.
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.
Also contact your doctor if you experience any worsening of your depression or other symptoms at any time during your treatment.

Stopping Treatment

Do not stop taking this medicine even if you begin to feel better.
Your doctor may decide that you should continue to take it for some time, even when you have overcome your problem. For best effect, this medicine must be taken regularly.
Do not stop taking your medicine suddenly.
If you suddenly stop taking your medicine, you may experience mild, but usually temporary, symptoms such as dizziness, feelings like pins and needles, sleeping problems (vivid dreams, nightmares, inability to sleep), feeling anxious, headaches, feeling sick (nausea), vomiting, sweating, feeling restless or agitated, tremor, feeling confused or disorientated, feeling emotional or irritable, diarrhoea (loose stools), visual disturbances, or fast or irregular heartbeats.
When you have completed your course of treatment, it is better that your dose is gradually reduced over a couple of weeks, rather than stopped abruptly.
Your doctor will tell you how to reduce the dosage so that you help avoid getting any unwanted effects.

If you forget to take it

If you are less than 12 hours late in taking your dose, take the missed dose as soon as you remember and then go back to taking your dose as you normally would.
If you are more than 12 hours late, then skip the dose you missed and take your next dose when you are meant to.
Do not take a double dose to make up for missed doses.
This may increase the chance of you experiencing side effects.
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 to help you remember.

If you take too much (overdose)

If you think that you or anyone else may have taken too much of this medicine, immediately telephone your doctor or the Poisons Information Centre (Tel: 13 11 26 in Australia) for advice. Alternatively go to the Accident and Emergency Department at your nearest hospital.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
If you take too much citalopram you may get symptoms of nausea (feeling sick), vomiting, dizziness, fast or slow heart beat or change in heart rhythm, decreased or increased blood pressure, tremor (shaking), agitation, dilated pupils of the eyes, drowsiness or sleepiness. Convulsions, coma, and rarely, temporary paralysis or weakness of muscles may occur.
A condition called serotonin syndrome may occur, with high fever, agitation, confusion, trembling and abrupt contraction of muscles.

While you are taking this medicine

Things you must do

Persons taking citalopram may be more likely to think about killing themselves or actually trying to do so, especially when citalopram is first started or the dose is changed. Tell your doctor immediately if you have thoughts about killing yourself or if you are close to or care for someone using citalopram who talks about or shows signs of killing him or herself.
All mentions of suicide or violence must be taken seriously.
Occasionally, the symptoms of depression may include thoughts of suicide or self-harm. It is possible that these symptoms continue or get worse until the full antidepressant effect of the medicine becomes apparent. This is more likely to occur if you are a young adult, i.e. 18 to 24 years of age, and you have not used antidepressant medicines before.
If you or someone you know or care for is showing any of the following warning signs of suicide-related behaviour while taking this medicine, contact your doctor or even go to the nearest hospital for treatment:
thoughts or talk of death or suicide
thoughts or talk of self-harm or harm to others
any recent attempts of self-harm
increase in aggressive behaviour, irritability or agitation
worsening of depression.
Follow your doctor’s instructions. Do not stop taking this medicine or change the dose without consulting your doctor, even if you experience increased anxiety at the beginning of treatment.
At the beginning of treatment certain patients may experience increased anxiety, which will disappear during continued treatment.
Tell your doctor immediately if you experience symptoms such as restlessness or difficulty in sitting or standing still.
These symptoms can also occur during the first weeks of treatment.
Contact your doctor immediately if you suddenly experience an episode of mania.
Some people with manic depression (bipolar disorder) may enter a manic phase. Symptoms of mania include lots of rapidly changing thoughts or ideas, exaggerated gaiety, being much more physically active and much more restless.
Sometimes you may not know that you are manic, so it may be helpful to have a friend or relative watch over you for any possible signs of change in your behaviour.
Visit your doctor regularly so they can check on your progress.
Tell your doctor immediately if you become pregnant.
If you are a woman of child-bearing age, you should avoid becoming pregnant while taking citalopram.
Make sure your midwife and/or doctor know you are taking citalopram. When taken during pregnancy, particularly in the last 3 months of pregnancy, medicines like citalopram may increase the risk of a serious condition in babies, called persistent pulmonary hypertension of the newborn (PPHN), making the baby breathe faster and appear bluish. These symptoms usually begin during the first 24 hours after the baby is born. If this happens to your baby you should contact your midwife and/or doctor immediately.
Low Potassium or Sodium
Some people (especially older people or those taking diuretics/water tablets or people who are dehydrated, have diarrhoea or vomiting or take certain antibiotics) may experience a lack of sodium or potassium in the blood when taking this medicine. Tell your doctor if you get a headache or start to feel dizzy, confused, forgetful, weak or fatigued, unsteady or unable to concentrate or if you get muscle weakness or spasms or abnormal heart beats or have problems breathing.
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking this medicine.
Tell any other doctors, dentists, and pharmacists who treat you that you are taking this medicine.
If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine.
If you start to breastfeed or are planning to breastfeed while taking this medicine, tell your doctor immediately.
If you are about to have any blood tests, tell your doctor that you are taking this medicine.
Your doctor may occasionally do tests to make sure the medicine is working and to prevent side effects. If you are taking certain other medicines or have heart problems you doctor will monitor you closely.
Keep all your doctor’s appointments so that your progress can be checked.
Tell your doctor if, for any reason, you have not taken your medicine exactly as prescribed.
Otherwise your doctor may think that it was not effective and change your treatment unnecessarily.
Tell your doctor if you feel this medicine is not helping your condition.
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.
Tell your doctor immediately if your heart beats unusually, and/or you feel short of breath, dizzy or faint.
Make sure you have enough tablets to last over weekends and holidays.

Things you must not do

Do not take this medicine to treat any other complaints unless your doctor tells you to.
Do not give your medicine to anyone else, even if they have the same condition as you.
Do not stop taking your medicine or change the dosage without checking with your doctor.
If you stop taking it suddenly, your condition may worsen, or you may have unwanted side effects.
Your doctor will tell you how to gradually reduce the dose of your medicine. This is usually done slowly, over 1 to 2 weeks, before stopping completely.

Things to be careful of

Be careful when driving or operating machinery until you know how this medicine affects you.
This medicine may cause nausea, fatigue, dizziness, visual disturbances or drowsiness in some people. If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.
Avoid alcohol while you are taking this medicine.
It is best not to drink alcohol while you are being treated for depression.
