What CITALOPRAM PFIZER is used for

CITALOPRAM PFIZER is used to treat depression.

It belongs to a group of medicines called selective serotonin reuptake inhibitors (SSRIs). They are thought to work by their actions on brain chemicals called amines which are involved in controlling mood.

Depression is longer lasting 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 PFIZER corrects this chemical imbalance and may help relieve the symptoms of depression.

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

This medicine is only available with a doctor's prescription.

CITALOPRAM PFIZER is not addictive. However, if you suddenly stop taking it, you may get side effects.

Tell your doctor if you get any side effects after stopping CITALOPRAM PFIZER.

How much to take

Take CITALOPRAM PFIZER exactly as your doctor has prescribed.

Follow all directions given to you by your doctor.

The standard dose for adults for this medicine is between 20 mg and 60 mg (one to three tablets) per day.

The recommended dose in elderly patients is 20 mg to 40 mg (one to two tablets) per day.

Your doctor will tell you how much doses to take each day. This depends on your condition and whether you are taking other medicines

  • Ask your doctor or pharmacist if you are unsure of the correct dose for you.
    They will tell you exactly how much to take.
  • Follow the instructions they give you.
    If you take the wrong dose, CITALOPRAM PFIZER may not work as well and your condition may not improve.


Your CITALOPRAM PFIZER should be swallowed with a drink of water.

Do not chew them.


Take your tablet at about the same time each day, either morning or evening. Taking your tablet at the same time each day will have the best effect. It will also help you to remember when to take it.

CITALOPRAM PFIZER can be taken with or without food.

How long to take CITALOPRAM PFIZER

Continue to take CITALOPRAM PFIZER even if it takes some time before you feel any improvement in your condition.

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 CITALOPRAM PFIZER. Your doctor will check your progress at regular intervals.

The duration of treatment may vary for each individual, but is usually at least 6 months.

In some cases the doctor may decide that longer treatment is necessary.

Continue taking your medicine for as long as your doctor tells you, even if you begin to feel better.

The underlying illness may persist for a long time and if you stop your treatment too soon, your symptoms may return.

Do not stop taking this medicine suddenly.

If the medicine is stopped suddenly you may experience mild, but usually temporary, symptoms such as dizziness, feelings like pins and needles, sleep disturbances (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, fluttering or pounding heartbeat (palpitations). When you have completed your course of treatment it is therefore advised that the dose of CITALOPRAM PFIZER 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 do not get these unwanted effects.

If you forget to take CITALOPRAM PFIZER

If you miss a dose and remember in less than 12 hours, take it straight away, and then go back to taking it as you would normally.

Otherwise, if it is almost time for your next dose, skip the dose you missed and take the next dose when you are meant to.

Do not take a double dose to make up for the dose you have missed.

If you are not sure what to do, ask your doctor or pharmacist.

If you have trouble remembering when to take your medicine, ask your pharmacist for hints.

If you take too much (overdose)

Immediately telephone your doctor or Poisons Information Centre - the telephone number in Australia is 131 126 or go to Accident and Emergency (Casualty) at your nearest hospital if you think you or anyone else may have taken too much CITALOPRAM PFIZER. Do this even if there are no signs of discomfort or poisoning.

You may need urgent medical attention.

Symptoms of an overdose may include nausea (feeling sick), dizziness, fast heart beat or change in heart rhythm, decreased or increased blood pressure, tremor (shaking), agitation, dilated pupils of the eyes, drowsiness and 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 CITALOPRAM PFIZER

Things you must do

If you are about to start any new medicine, tell your doctor or pharmacist that you are taking CITALOPRAM PFIZER.

Tell any other doctors, dentists and pharmacists who are treating you that you are taking CITALOPRAM PFIZER.

If you become pregnant while taking CITALOPRAM PFIZER tell your doctor immediately.

Tell your doctor immediately if you have any suicidal thoughts or other mental or mood changes.

All mentions of suicide or violence must be taken seriously.

If you or someone you know demonstrates any of the following warning signs of suicide-related behaviour while taking CITALOPRAM PFIZER, contact a health care provider immediately, or even to 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.

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. under thirty years of age and you have not used antidepressive medicines before.

Follow your doctor's orders and do not stop the treatment or change the dose without consulting your doctor even if you experience increased anxiety at the beginning of treatment.

In the beginning of the 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 as soon as possible if you suddenly experience an episode of mania.

Some patients with bipolar disorder (manic depression) may enter into a manic phase. This is characterised by profuse and rapidly changing ideas, exaggerated gaiety and excessive physical activity.

Sometimes you may be unaware of the above-mentioned symptoms and therefore you may find it helpful to ask a friend or relative to help you to observe the possible signs of change in your behaviour.

Things you must not do

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

Do not take CITALOPRAM PFIZER to treat any other complaints unless your doctor tells you to.

Do not stop taking CITALOPRAM PFIZER, or lower the dosage, without checking with your doctor.

Do not let yourself run out of medicine over the weekend or on holidays.

Suddenly stopping CITALOPRAM PFIZER may cause unwanted discontinuation symptoms such as dizziness, headache and nausea. Your doctor will tell you when and how CITALOPRAM PFIZER should be discontinued. Your doctor will gradually reduce the amount you are using, usually over a period of one to two weeks, before stopping completely.

Things to be careful of

Be careful driving or operating machinery until you know how CITALOPRAM PFIZER affects you.

It may cause nausea, fatigue and dizziness in some people, especially early in the treatment. 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 not advisable to drink alcohol while you are being treated for depression.
