2 Before you take Citalopram Tablets
Do not take Citalopram tablets if you:
- are allergic (hypersensitive) to citalopram or any of the other ingredients (See Section 6).
- are taking MAO (monoamine oxidase) inhibitors (medicines used for treatment of depression or Parkinson’s disease). The
MAO-inhibitor called selegiline may be used in combination with citalopram, but only at doses of less than 10 mg per day.
- have recently taken MAO-inhibitors. Depending on the type of MAO-inhibitor you used to use, you may have to wait for up to
14 days after stopping the MAO-inhibitor before starting with Citalopram. If you stop taking Citalopram and want to start using
MAO-inhibitors, you have to wait for at least 7 days. Please ask your doctor for advice.
- are taking linezolid unless you are under close medical supervision and monitored on blood pressure.
- are taking pimozide (an antipsychotic medicine).
- are born with or have had an episode of abnormal heart rhythm (seen at ECG; an examination to evaluate how the heart is
- take medicines for heart rhythm problems or that may affect the heart’s rhythm. Also refer to the section “Taking other
Use in children and adolescents under 18 years
Citalopram tablets should normally not be used by children and adolescents under 18 years. Also, you should know that patients under 18
have an increased risk of side effects such as suicide attempt, suicidal thoughts and hostility (predominantly aggression, confrontional
behaviour and anger) when they take this class of medicines. Despite this, your doctor may prescribe Citalopram for patients under 18
because he/she decides that this is in their best interest. 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 this medicine. Also, the long-term safety effects concerning growth, maturation and cognitive and behavioural
development of Citalopram in this age group have not yet been demonstrated.
Thoughts of suicide and worsening of your depression
If you are depressed 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.
- 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 and ask them to read this leaflet. You might
ask them to tell you if they think your depression is getting worse, or if they are worried about changes in your behaviour.
Take special care and check with your doctor before taking Citalopram Tablets if you:
- have diabetes (as your doctor may need to adjust the dose of insulin your antidiabetic medicine)
- have had seizures or have epilepsy. You will be carefully monitored by your doctor. Treatment with Citalopram should be
stopped if seizures occur or if you start having more seizures than usual.
- are receiving electro-convulsive treatment (ECT).
- have or have had episodes of mania (overactive behaviour or thoughts).
- have a history of bleeding disorders or are using medicines that affect blood clotting or increase the risk of
- suffer from psychosis with depressive episodes, because the psychotic symptoms may increase.

- have or are prone to heart rhythm disorders (QTinterval prolongation or have suspected congenital QT-syndrome)
- suffer or have suffered from heart problems or have recently had a heart attack
- have a low resting heart-rate and/or you know that you may have salt depletion as a result of prolonged severe
diarrhoea and vomiting (being sick) or usage of diuretics (water tablets)
- experience a fast or irregular heartbeat, fainting, collapse or dizziness on standing up which may indicate abnormal
functioning of the heart rate
- suffer from low blood levels of potassium or magnesium (hypokalaemia/hypomagnesaemia).
- suffer from low blood sodium (hyponatremia) or SIADH (inappropriate secretion of the anti-diuretic hormone which
regulates the water balance in the body). These disorders have been reported rarely when taking Citalopram (mainly in the elderly) and
generally they stabilize on stopping treatment.
- If whilst taking Citalopram you develop symptoms signs such as restlessness, confusion, trembling, excitation, fever, shivering,
hallucinations, muscle cramps, rapid heart beat, tell your doctor at once.
These may be a first sign of a condition called serotonin syndrome. He/she will stop your treatment with Citalopram
- If you start feeling restless and are no longer able to stand or sit still, please inform your doctor, since you may be suffering
from a side-affect called akathisia.
- At the start of treatment, sleeplessness and intense excitation can occur. Patients with panic disorder may experience
intensified anxiety symptoms in the first 2 weeks of treatment. In both cases, the doctor may adjust the dose accordingly.
- After discontinuation of therapy withdrawal symptoms may appear: dizziness, sleep disturbance, agitation, anxiety, nausea
and/or vomiting, tremor of headache are the most common symptoms.
They usually occur within the first few days, and last for about 14 days. It is advised to gradually stop treatment by lowering the dose
over a period of
several weeks. Please consult your doctor before discontinuing treatment.
Taking other medicines
Do not take Citalopram if you take medicines for heart rhythm problems or medicines that may affect the heart’s rhythm, e.g. such
as Class IA and
III antiarrhythmics, antipsychotics (e.g. fentiazine derviatives, pimozide, haloperidol), tricyclic antidepressants , certain antimicrobial
agents (e.g. sparfloxacin, moxifloxacin, erythromycin IV, pentamidine, anti-malarian treatment particularly halofantrine), certain
antihistamines (astemizole, mizolastine). If you have any further questions about this you should speak to your doctor.
The following medicinal products must not be used together with Citalopram Tablets:
- MAO-inhibitors (medicinal products against depression or Parkinson’s disease). This applies both to irreversible MAO-inhibitors
like phenelzine and to reversible MAO-inhibitors like moclobemide.
The MAO-inhibitor called selegiline may be used in combination with citalopram, but only at doses of less than 10 mg per day.
- If you have recently taken MAO-inhibitors.
Depending on the type of MAO-inhibitor you used to use, you may have to wait for up to 14 days after stopping the MAO-inhibitor before
starting with Citalopram. If you stop taking Citalopram and want to start using MAO-inhibitors, you have to wait for at least 7 days.
Please ask your doctor for advice.

in the brain)
- other medicines for depression: tricyclic antidepressants, other serotonin re-uptake inhibitors or medicines containing
- tramadol (to treat severe pain).
- St. John’s Wort (Hypericum perforatum) as the above medicines may lead to ‘serotonin syndrome’ (see ‘Other warnings’).
- desipramine (to treat depression) as the blood level of desipramine may be increased and a reduced dose may be needed.
- blood-thinning medicines (warfarin), other oral anticoagulants or medicines influencing blood clotting (e.g. non-steroidal
acetylsalicylic acid (aspirin), NSAID’s, dipyridamole and ticlopidine) as use with citalopram may lead to increased/prolonged
- cimetidine (to reduce gastric acid)
- medicines to treat stomach ulcers (e.g. omeprazole, esomeprazole, lansoprazole)
- fluvoxamine (to treat depression)
- neuroleptics (to treat schizophrenia) as use with Citalopram can cause seizures.
- metoprolol (for high blood pressure or heart failure) as an increase in the blood level of metoprolol has been

Taking Citalopram Tablets with food and drink
You are advised not to drink alcohol with this medicine. The film-coated tablets may be taken with or without food.
Pregnancy, breast-feeding and 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.
Data suggest that the use of Citalopram during pregnancy does not lead to problems with the foetus. Therefore, Citalopram may be used if
you are pregnant or planning to become pregnant taking into account the following issues.
If you are taking Citalopram during pregnancy, you should not stop treatment with Citalopram abruptly.
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.
Citalopram passes into breast milk in small amounts.
There is a risk of an effect on the baby. If you are taking Citalopram, talk to your doctor before you start breastfeeding.
Ask your doctor or pharmacist for advice before taking any medicine.
Driving and using machines
Citalopram Tablets may affect your ability to make judgements and to react to emergencies. Make sure you are not affected in this way
before you drive or operate machinery. If you are affected in any way, you should NOT drive or operate machinery.

shakiness of the arms and legs (tremor), confusion, sweating, headache, diarrhoea, fluttering or pounding heartbeat (palpitations),
emotional instability, irritability, and visual disturbances.

more severe, or
go on for longer. If you get severe withdrawal effects when you stop taking Citalopram, please see your doctor. He or she may ask you to
start taking your
tablets again and come off them more slowly. If you do get withdrawal effects, you will still be able to stop Citalopram.
