How does citalopram work?
Volver al contenidoCitalopram increases the amount of circulating serotonin available in your brain. This may help the symptoms of depresión o panic disorder in some people.
Depression and panic disorders can develop for no apparent reason, or they may be triggered by a life event such as a relationship problem, a bereavement, or an illness.
Brain cells, called neurons, release a number of chemicals which go on to stimulate other neurons. This leads to electrical impulses which result in many functions controlled by the brain. Serotonin is one such chemical in the brain. Once released, it stimulates other neurons and is then taken back up into the neuron cells and recycled.
Citalopram side effects
Volver al contenidoThe most common side effects of citalopram are:
Sentirse mal (náuseas).
Estar enfermo (vómitos).
Indigestión.
Estreñimiento.
Diarrea.
Feeling sleepy, weak or tired.
Boca seca.
Dolor de cabeza.

Cambios de humor.
Encontrará una lista completa en el prospecto del fabricante que se suministra con su medicamento. Los efectos no deseados a menudo mejoran a medida que su cuerpo se adapta al nuevo medicamento, pero hable con su médico o farmacéutico si alguno de los siguientes persiste o se vuelve problemático.
Importante: a few people taking citalopram have developed an allergic-type reaction. Although this is quite rare, you should contact your doctor straightaway if you develop any swelling around your face, any difficulties breathing, or a severe rash.
On rare occasions, medicines that affect the level of serotonin in the brain can cause it to go too high and cause problems. The risk is higher if you are taking more than one medicine with this effect. Seek medical attention if you develop any combination of the following:
Músculos rígidos o movimientos 'bruscos'.
Latidos del corazón inusualmente rápidos.
High temperature (fever), feeling sick (nausea) or being sick (vomiting), diarrhoea.
Sentirse delirante o ver visiones (alucinar).
If you experience any other symptoms that you think may be due to this medicine, speak with your doctor or pharmacist for further advice.

Who should not take citalopram?
Volver al contenidoSome medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking citalopram it is important that your doctor knows:
Si estás embarazada, intentando tener un bebé o amamantando.
If you have any liver or kidney disorders.
If you have a heart condition or have been told you have an irregular heartbeat.
Si tienes epilepsia.
Si tienes niveles altos de azúcar en la sangre (diabetes mellitus).
If you have raised pressure in your eye(s) (glaucoma).
If you have ever had a bleeding disorder.
If you have ever had abnormally 'high' moods, called mania.
If you are being treated with electroconvulsive therapy (ECT).
Si alguna vez has tenido una reacción alérgica a un medicamento.
If you have taken an antidepressant known as a monoamine-oxidase inhibitor (MAOI) within the previous two weeks.
Si está tomando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que esté disponible para comprar sin receta, así como medicamentos herbales y complementarios.
How to take citalopram
Volver al contenidoBefore you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about citalopram and will provide you with a full list of the side effects which you may experience from taking it.
Take citalopram exactly as your doctor tells you to. It is prescribed as a once-daily dose. You can generally take it at a time to suit you, but try to take your doses at the same time of day, each day. There are several strengths of tablet available, so your doctor will tell you which strength is right for you. This information will also be on the label of the pack you have been supplied with.
If you are being treated for a panic disorder, your doctor may prescribe a low dose for you to begin with. This is because some people develop anxiety during the first two weeks, and slowly increasing the dose helps to reduce this.
If you have been given Cipramil® oral drops, your doctor will tell you how many drops to take each day. Count the correct number of drops into a drink of water, orange juice or apple juice. Stir it briefly, and then drink it straightaway.
You can take citalopram before or after food.
Si olvida tomar una dosis, tómela tan pronto como lo recuerde. Si no lo recuerda hasta el día siguiente, omita la dosis olvidada. No tome dos dosis juntas para compensar una dosis olvidada.
Obteniendo el máximo de tu tratamiento
Volver al contenidoYou may feel that citalopram is not working for you straightaway. It can take a week or two after starting this treatment before the effect begins to build up, and 4-6 weeks before you feel the full benefit. Do not stop taking it after a week or two, even if you feel it is not helping.
Intenta mantener tus citas regulares con tu médico. Esto es para que tu médico pueda verificar tu progreso.
If you drink alcohol, ask your doctor for advice. Your doctor is likely to recommend that you do not drink alcohol while you are on citalopram, as it increases the risk of side effects, such as feeling sleepy.
If you have diabetes, you may need to check your blood sugar (glucose) more frequently, as citalopram may affect the levels of sugar in your blood. Your doctor will be able to advise you about this.
If you buy any medicines, check with a pharmacist that they are safe to take with citalopram. This is because several medicines which are available from general retail outlets can interfere with this treatment. In particular, do not take the herbal remedy St John's wort, and ask for advice before buying any anti-inflammatory painkillers.
There are several types of antidepressants and they differ in their possible side effects. If you find that citalopram does not suit you then let your doctor know, as another may be found that will.
While you are taking citalopram, you may have thoughts about harming yourself or ending your life. These thoughts may also be associated with your condition. It is very important that you tell your doctor about this if it happens.
You should expect that a course of treatment will last for several months. This is normal and helps to prevent your symptoms from recurring.
Do not stop taking citalopram unless your doctor tells you to do so. Stopping treatment suddenly can cause problems and your doctor will probably want you to reduce your dose gradually when this becomes necessary.
A few people taking citalopram find that their skin is more sensitive to sunlight than normal. Until you know how your skin reacts, use a sun cream with a high sun protection factor (SPF) in strong sunlight.
How to store citalopram
Volver al contenidoMantenga todos los medicamentos fuera del alcance y la vista de los niños.
Almacenar en un lugar fresco y seco, lejos del calor y la luz directos.
You can use citalopram drops for 16 weeks after first opening the bottle. Do not use the drops after this time.
