What is trazodone used for?
Trazodone is used to treat depresión y ansiedad. It is a type of medicine called a tricyclic-related antidepressant.
Antidepresivos like trazodone are used to ease symptoms such as low mood, poor sleep and poor concentration. This in turn allows you to function more normally and cope better with any difficult circumstances. Trazodone also helps to reduce the symptoms of anxiety, even if you are not depressed.
Depression and anxiety can develop for no apparent reason, or they may be triggered by a life event such as a relationship problem, bereavement, or illness.

Who should not take trazodone?
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 trazodone it is important that your doctor or pharmacist knows:

If you have thyroid problems.
If you have liver, kidney or heart problems.
If you have epilepsy or diabetes (diabetes mellitus).
If you are troubled by constipation which lasts several days.

How to take trazodone
Volver al contenidoRead the manufacturer's printed information leaflet from inside your pack. This will give you more information about trazodone and a full list of side effects which you may experience from taking it.
You may be prescribed trazodone to take once a day, at bedtime. Some doctors, however, may recommend smaller doses taken two or three times a day. Your doctor will tell you which is right for you and your dose will also be on the label of the pack to remind you.
Take trazodone exactly as your doctor has told you to. It can cause drowsiness so your doctor may advise you to take a smaller dose to begin with, and then to increase it as your body gets used to the medicine.
Take trazodone after meals. If you are taking your doses at bedtime, have a light snack beforehand.
If you forget to take a dose take it as soon as you remember, unless it is nearly time for your next dose in which case leave out the forgotten dose. Do not take two doses together to make up for a missed dose.

You may feel that trazodone is not working for you straightaway. It can take a week or two after starting it before the effect begins to build up, and 4-6 weeks before you feel the full benefit. It is important that you do not stop taking it after a week or so, thinking it is not helping.
If you feel depressed, you may have distressing thoughts and think about harming yourself or ending your life. If this happens, it is very important that you tell your doctor about this as soon as possible.
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 trazodone, as it increases the risk of side effects, such as feeling sleepy.
If you are taking trazodone for depression, your doctor may ask you to carry on taking it even after you feel better. This is to help stop the depression from returning.
It is normal for a course of treatment to last for around six months after your symptoms have eased.
Continue to take trazodone unless your doctor tells you otherwise. Stopping treatment suddenly can sometimes cause problems and your doctor may want you to reduce your dose gradually if this is necessary.
If you buy any medicines, check with a pharmacist that they are suitable for you to take. This is because a number of medicines which can be bought from pharmacies and other retail outlets can increase the risk of side effects from trazodone. These include antihistamine medicines, and St John's wort.
If you have diabetes you may need to check your blood sugar (glucose) more frequently. This is because trazodone may affect the levels of sugar in your blood. Your doctor will advise you about this.
If you are having any medical or dental treatment, tell the person carrying out the treatment that you are taking this medicine.
