Patient leaflet - Citalopram 10 mg film-coated tablets

1 What Citalopram is and what it is used for

Citalopram belongs to a group of antidepressants known as Selective Serotonin Reuptake Inhibitors (SSRIs).

Citalopram is used for the treatment of:

  • Depressive illnesses (major depressive episodes)
  • Panic disorders with or without agoraphobia (e.g. strong

    fear of leaving the house, entering shops, or fear of public places)

2 What you need to know before you take Citalopram

Do not take Citalopram:

  • If you are allergic (hypersensitive) to Citalopram, other

    SSRI antidepressants or any of the other ingredients of this medicine (see section 6 “Contents of the pack and other information”)

  • If you are taking or have recently taken medicines used

    to treat depression called Monoamine Oxidase Inhibitors (MAOIs): e.g moclobemide or you are being treated with the non-selective MAOI linezolid (an antibiotic medicine), unless you are being closely monitored (see “Other medicines and Citalopram” section) .The irreversible MAOI selegiline (used to treat Parkinson`s disease) may be used in combination with Citalopram in doses not exceeding 10mg selegiline per day. Before starting treatment with Citalopram, you may have to wait for up to 14 days after stopping the use of a MAOI. When changing from Citalopram, you may have to wait for at least 7 days before you start taking MAOIs.

  • If you are taking the medicine pimozide, used to treat

    mental disorders (see “Other medicines and Citalopram” section)

  • If you are born with or have had an episode of abnormal

    heart rhythm (seen at ECG; an examination to evaluate how the heart is functioning)

  • If you take medicines for heart rhythm problems or that

    may affect the heart`s rhythm

Warnings and precautions

Talk to your doctor before taking Citalopram if:

  • You are older (above 65 years of age)
  • You suffer from kidney and liver problems
  • You suffer from a panic disorder as you may need to

    start treatment with a low dose

  • You are at risk of a decreased salt (sodium) level in the

    blood (hyponatraemia)

  • You start to feel restless and cannot sit or stand still

    (akathisia). This is most likely to occur within the first few weeks of treatment. Increasing your dose of Citalopram may make this condition worse

  • You have a history of feeling/being elated/over-excited

    which causes unusual behaviour (mania). If you have a manic episode, your treatment with Citalopram should be discontinued

  • You have diabetes as the dose of your diabetic medicine

    may need to be adjusted (see “Other medicines and Citalopram” section)

  • You have or are at risk of increased pressure in the eye

    (glaucoma) as Citalopram can cause dilation of the pupils (mydriasis)

  • You have unstable epilepsy, Citalopram should be

    avoided. If you have controlled epilepsy, you should be carefully monitored. Citalopram should be discontinued if you develop fits (seizures) or there is an increase in the frequency

  • You are receiving ECT (Electro-Convulsive Treatment)
  • You have a history of bleeding disorders, if you are

    pregnant (see ‘Pregnancy’1) or are taking anticoagulant medicines (for thinning the blood) (see “Other medicines and Citalopram section”)

  • You are taking serotonergic medicines (antidepressants)

    such as sumatriptan or other triptans, tramadol, oxitriptan, and tryptophan (see “Other medicines and Citalopram” section) as on rare occasions, development of serotonin syndrome have occurred. Treatment with Citalopram should be discontinued if symptoms such as agitation, shakiness (tremor), involuntary muscle twitching (myoclonus) and fever (hyperthermia) should occur

  • You are taking St. John’s Wort, a herbal remedy used to

    treat depression as it may result in an increase in undesirable effects (see “Other medicines and Citalopram” section).

  • You have suspected congenital long qt- syndrome or

    suffer from low blood levels of potassium or magnesium (hypokalaemia/hypomagnesaemia).

  • You suffer from or have a history of heart problems or

    have recently had a heart attack. If signs of irregular heartbeat (cardiac arrhythmia) occur during treatment with Citalopram, treatment should be withdrawn and an ECG should be performed

  • Medicines like Citalopram (so called SSRIs/SNRIs) may

    cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms have continued after stopping treatment.

Thoughts of suicide and worsening of your depression or anxiety disorder

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 an adult. Information from clinical trials has shown an increased risk of suicidal behaviour in young adults aged less than 25 years old 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 them to tell you if they think your depression or anxiety disorder is getting worse, or if they are worried about changes in your behaviour.

Use in children and adolescents under the age of 18 years:

Citalopram should not be used in the treatment of children and adolescents under the age of 18 years. Patients under the age of 18 years have an increased risk of suicide-related behaviours (suicide attempt and suicidal thoughts) and hostility (predominantly aggression, oppositional behaviour and anger) when treated with antidepressants. If your doctor has prescribed Citalopram for a patient under 18 and you want to discuss this, please go back to your doctor. You should inform your doctor if any of the symptoms listed above develop or worsen when patients under 18 are taking Citalopram. Studies of people under 18 taking Citalopram have not shown for certain whether or not the medicine affects growth, or development of the brain or body.

Pregnancy, breast-feeding and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.

Pregnancy

Do not take Citalopram if you are pregnant or think you may be pregnant, unless you and your doctor have discussed the risks and benefits involved. You should not stop treatment with Citalopram abruptly during pregnancy. Contact your doctor if you wish to pause or stop the treatment.

Make sure your midwife and/or doctor know you are on 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.

If you take Citalopram, particularly during the last 3 months of pregnancy, your newborn child may experience serious side effects such as breathing difficulties, bluish skin/lips (cyanosis), irregular breathing with breathing pauses (apnoea), temperature fluctuations, fits (seizures), lack energy (lethargy), sleeping difficulties, difficulty in feeding, being sick (vomiting), low level of sugar in the blood (hypoglycaemia), stiff or floppy muscles, abnormally increased reflexes, shaking (tremor), extreme nervousness or nervous shaking, irritability, lacking energy (lethargy), constant crying and drowsiness (somnolence). If your baby has any of these symptoms when it is born, contact your midwife/and or doctor immediately.

If you take Citalopram near the end of your pregnancy there may be an increased risk of heavy vaginal bleeding shortly after birth, especially if you have a history of bleeding disorders. Your doctor or midwife should be aware that you are taking Citalopram so they can advise you.

Breast-feeding

Citalopram passes into breast milk in small amounts and there is a risk of an effect on the baby. If treatment with Citalopram is considered necessary, discontinuation of breast-feeding should be considered

Fertility

Citalopram 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.

Driving and using machines

Citalopram has minor to moderate influence on the ability to drive and use machines as it can reduce the ability to make judgements and react to emergencies. If this occurs, you should not drive or use machines. .

Citalopram contains lactose

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.

If you stop taking Citalopram

It is important that you keep taking Citalopram for as long as your doctor has told you to.

Abrupt discontinuation should be avoided. When you stop treatment with Citalopram the dose should be gradually reduced over a period of at least one to two weeks in order to reduce the risk of withdrawal reactions. If side effects should occur following a decrease in the dose or upon discontinuation of treatment, then resuming the previously prescribed dose may be considered. Subsequently, your doctor may continue decreasing the dose, but at a more gradual rate.

Withdrawal symptoms are common, particularly if treatment is stopped suddenly e.g. feeling dizzy, tingling or numbness in the hands or feet (paraesthesia), finding it difficult to sleep (insomnia) or having intense dreams, agitation, anxiety, feeling (nausea) or being sick (vomiting), shaking (tremor), confusion, sweating, headache, diarrhoea, feeling your heartbeat (palpitations), feeling emotional, irritability, visual disturbances. Most people find that any effects are mild to moderate and go away within two weeks. Some people find they are more severe and last longer (2-3 months or more).

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
