Warnings and precautions
Consult your doctor or pharmacist before starting to take this medicine.
Suicidal thoughts and worsening of depression or anxiety disorder
If you are depressed and/or suffer from anxiety disorders, you may sometimes have thoughts of self-harm or suicide. These can increase when taking antidepressants for the first time, as all these medicines need time to start working, usually around two weeks, but in some cases, the time could be longer.
You may be more prone to having these types of thoughts:
If you have thoughts of self-harm or suicide at any time, contact your doctor or go to the hospital immediately.
It may be helpful to inform a family member or close friendthat you are depressed or have an anxiety disorder, and ask them to read this prospectus. You can ask them if they think your depression or anxiety disorder has worsened, or if they are concerned about changes in your attitude.
The following cases are described in which you should only take citalopram under certain conditions and with special caution. Consult your doctor about this. This also applies if this information applied to you in the past.
Do not take citalopram
You should have special caution when taking citalopram if
Tell your doctor if you have altered liver or kidney function. Your doctor may adjust the dose (see section 3).
In patients who suffer from epilepsy, treatment with citalopram should be discontinued if seizures occur or if their frequency increases (see also section 4, "Possible side effects").
Citalopram may also affect blood sugar control in patients with diabetes.
You may need to adjust your antidiabetic treatment.
During treatment with citalopram, rare cases of hyponatremia (low sodium levels in the blood) have been reported, possibly caused by inadequate secretion of antidiuretic hormone (SIADH), which was generally reversible after treatment discontinuation. Most reports referred to elderly patients, patients taking diuretics, or patients with volume deficit for other reasons. The signs may include discomfort with muscle weakness and confusion.
If you suffer from manic-depressive illness, you may experience a manic phase. If you enter a manic phase characterized by an unusual and rapid change of ideas, inappropriate happiness, and excessive physical activity, contact your doctor. In this case, treatment with citalopram should be suspended by your doctor.
Important information about your disease
Improvement does not occur immediately. After starting treatment with citalopram, it may take several weeks before you notice any improvement. In the treatment of anxiety disorder, it usually takes 2-4 weeks before noticing any improvement.
Some patients with anxiety disorder may experience an increase in anxiety at the beginning of treatment. However, these symptoms usually disappear on their own after 14 days of treatment. To reduce these anxiety symptoms, a low initial dose of 10 mg of citalopram is recommended during the first week of treatment (see section 3).
It is very important that you follow your doctor's instructions exactly and do not interrupt treatment or change the dose without consulting your doctor.
Medicines like citalopram (called SSRIs/SNRIs) may cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms persist after treatment discontinuation.
Restlessness/difficulty staying still or stopping
During the first weeks of treatment, symptoms such as restlessness, difficulty staying still, or stopping (akathisia) may appear. Inform your doctor immediately if you experience these symptoms. Then, a dose adjustment may be useful.
Withdrawal symptoms observed when stopping treatment with a Selective Serotonin Reuptake Inhibitor (SSRI)
When you stop treatment with citalopram, especially if it is sudden, you may feel withdrawal symptoms (see "How to take citalopram" and "Possible side effects"). They are common when treatment is stopped. The risk is greater when citalopram has been used for a long time, in high doses, or when the dose is reduced too quickly. Many people find that the symptoms are mild and disappear on their own within two weeks. However, in some patients, they can be severe or prolonged (2-3 months or more). If you experience severe withdrawal symptoms when stopping treatment with citalopram, please contact your doctor. You can ask them to start taking your tablets again and stop them more gradually.
In relation to the use of medicines like citalopram, rare cases of altered bleeding time and/or hemorrhagic disorders (e.g., ecchymosis, gynecological hemorrhages, gastrointestinal bleeding, and other cutaneous or mucous bleeding) have occurred.
Caution should be exercised in patients with a history of hemorrhagic disorders and during concomitant use of medicines that may increase the risk of bleeding (see also section "Other medicines and citalopram").
If you suffer from psychotic depression, treatment with citalopram may increase psychotic symptoms (e.g., hallucinations or delusions).
Currently, there is little clinical experience with the concomitant use of citalopram and electroconvulsive therapy, so caution is recommended.
Tell your doctor if you have eye problems such as certain types of glaucoma (increased intraocular pressure). Citalopram should be used with caution in this case.
Elderly patients (over 65 years)
Elderly patients are more sensitive to the effects of antidepressants, so the dose of citalopram should be adjusted by your doctor. Please inform your doctor if you experience any side effects.
Children and adolescents under 18 years
Citalopram should not be used normally in children and adolescents under 18 years. Moreover, you should know that patients under 18 years have a higher risk of suffering from adverse effects such as suicidal attempts, suicidal thoughts, and hostility (mainly aggressiveness, confrontational behavior, and anger) when taking this class of medicines.
Despite this, your doctor may prescribe citalopram to patients under 18 years when they decide what is most convenient for the patient. If your doctor has prescribed citalopram to a patient under 18 years and you want to discuss this decision, please go back to your doctor. You should inform your doctor if any of the symptoms listed above progress or worsen when patients under 18 years are taking citalopram. Also, the long-term effects on safety and related to growth, maturity, and cognitive and behavioral development of citalopram in this age group have not yet been demonstrated.
Other medicines and citalopram
Tell your doctor or pharmacist if you are taking, have recently taken, or may need to take any other medicine.
Take only the medicines that your doctor has prescribed to you at the same time as citalopram.
Do not take citalopram
Citalopram should not be taken with sumatriptan and similar medicines (medicines for the treatment of migraine), tramadol (medicines for the treatment of pain), tryptophan, or oxitriptan (serotonin precursors), as it may cause an increase in the power of serotoninergic effects. There have also been isolated cases of "serotonin syndrome" (for its explanation, see section 4) when citalopram is combined with moclobemide or buspirone.
Concomitant administration of citalopram and herbal preparations containing St. John's Wort(herbal medicine for the treatment of depression) should be avoided due to the increased risk of adverse effects.
Concomitant administration of cimetidine, lansoprazole, and omeprazole (for the treatment of stomach ulcers), fluconazole (for the treatment of fungal infections), fluvoxamine (antidepressant), and ticlopidine (to reduce the risk of stroke) may cause an increase in the concentration of citalopram in the blood. Dose adjustment may be necessary.
Caution should be exercised when taking flecainide or propafenone (medicines used to treat irregular heart rhythm), desipramine, clomipramine, and nortriptyline (medicines used to treat depression) or risperidone, tioridazine, and haloperidol (medicines used to treat schizophrenia and psychosis) at the same time. Dose adjustment may be necessary.
Concomitant use of metoprolol (medicine for the treatment of high blood pressure and heart disease) causes an increase in the level of metoprolol in the blood. Dose adjustment may be necessary.
Although interactions with the concomitant use of citalopram and lithium (for the prevention and treatment of manic-depressive disorders) have been rarely reported, treatment should be carefully monitored.
Caution should be exercised when taking citalopram at the same time as other anticoagulant medicines (anticoagulants such as warfarin), medicines that affect platelet function, or other medicines that increase the risk of bleeding (see also "Warnings and precautions" in section 2). These medicines include non-steroidal anti-inflammatory drugs (ibuprofen, naproxen, acetylsalicylic acid, etc.), dipyridamole, antipsychotics, and ticlopidine.
Caution should be exercised when using medicines that decrease potassium or magnesium levels in the blood, as this increases the risk of suffering from heart rhythm disorders, which pose a risk to life.
Caution should be exercised when using imipramine and desipramine (both medicines used to treat depression) concomitantly. Dose adjustment of desipramine may be necessary.
Citalopram may decrease the seizure threshold. Therefore, caution should be exercised when treating concomitantly with medicines that also have a possible risk of decreasing the seizure threshold, e.g., mefloquine (used to treat malaria), bupropion (used to treat depression), tramadol (strong analgesic), neuroleptics (medicines for the treatment of schizophrenia or psychosis), and medicines for the treatment of depression (SSRIs).
Interactions between citalopram and clozapine (medicine used to treat psychosis) have been reported, which may increase the risk of adverse effects associated with clozapine. The nature of these interactions is not known.
Citalopram with alcohol
Although there is no evidence of interactions between citalopram and alcohol, alcohol consumption should be avoided during treatment with this medicine.
Pregnancy, breastfeeding, and fertility
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.
Pregnancy
Do not take citalopram if you are pregnant or plan to become pregnant, unless you and your doctor have discussed the risks and benefits.
Do not stop treatment with citalopram abruptly during pregnancy. Consult your doctor if you want to stop or interrupt treatment.
Make sure your midwife and/or doctor knows that you are being treated with citalopram. When medicines like citalopram are taken during pregnancy, particularly in the last three months of pregnancy, the risk of suffering from a serious disorder in newborns, called persistent pulmonary hypertension of the newborn (PPHN), may be increased, which makes the baby breathe more rapidly and have a bluish appearance. These symptoms usually appear within the first 24 hours after the baby's birth. If this happens to your baby, you should contact your midwife and/or doctor immediately.
If you are taking citalopram during the last three months of pregnancy and up to the day of your child's birth, you may experience serious adverse effects or withdrawal, such as respiratory difficulties, blue-tinged skin/lips, irregular breathing with breathing pauses, temperature fluctuations, seizures, apathy, difficulty sleeping, difficulty feeding, vomiting, low blood sugar levels, stiff or flexible muscles, increased reflexes, tremors, extreme nervousness or agitation, irritability, constant crying, and drowsiness.
If your newborn baby suffers from any of these symptoms, contact your doctor immediately; they will be able to advise you.
If you take citalopram in the final stage of pregnancy, there may be an increased risk of abundant vaginal bleeding shortly after delivery, especially if you have a history of hemorrhagic disorders. Your doctor or midwife should know that you are taking citalopram to be able to advise you.
Breastfeeding
Citalopram is excreted in breast milk in small amounts. There is a risk of effects on the child. If you are taking citalopram, inform your doctor before starting breastfeeding.
Fertility
Citalopram has been shown to reduce sperm quality in animals. This could theoretically affect fertility, but so far, no effect on fertility has been observed in humans.
Driving and using machines
Citalopram has a mild to moderate influence on the ability to drive and use machines. Do not drive or use machines until you know how this medicine affects you. Normally, citalopram does not affect the ability to perform daily activities. However, if you feel dizzy or drowsy when you start taking this medicine, you should be careful when driving, operating machinery, or performing tasks that require you to be alert until these effects disappear. If you are not sure, consult your doctor if you can perform the aforementioned activities.

In mild to moderate hepatic insufficiency, an initial dose of 10 mg of citalopram per day is recommended for the first two weeks of treatment. Patients with hepatic insufficiency should not take more than 20 mg of citalopram per day. Your doctor should monitor your liver function. Caution and extremely careful dosing are recommended if you have severe liver problems.
No dose adjustment is necessary in case of mild or moderate renal insufficiency. The use of citalopram is not recommended in patients with severe renal insufficiency (creatinine clearance less than 30 ml/min) due to lack of experience.
Use in children and adolescents under 18 years old
Citalopram should not normally be used in children and adolescents under 18 years old (see "Warnings and precautions").
How and when should you take citalopram?
Citalopram is for oral use.
The tablets are taken once a day.
The tablets can be taken at any time of day, regardless of meals, with plenty of liquid (e.g., 1 glass of water). Do not chew the tablets because they have a bitter taste.

How long should you take citalopram?
Note that the effect of citalopram may take several weeks. It may take 2 to 4 weeks before you start to feel better. Therefore, expect an improvement only after some time.
In the treatment of anxiety disorders with and without agoraphobia, the maximum effect is achieved after about three months of treatment.
The total duration of treatment varies greatly from person to person (usually at least 6 months) and is determined by your doctor. Respect this time even if you already feel better or are symptom-free, to avoid a new worsening or relapse of the disease.
If you take more citalopram than you should
If you or someone else has taken a quantity greater than the prescribed dose, inform your doctor immediately or go to the emergency department of the nearest hospital. Do this even if you have no symptoms and take the citalopram package with you.
