About doxepin

What is doxepin used for?

Doxepin is used for the treatment of depressão. It belongs to a group of medicines called antidepressivos tricíclicos.

Doxepin can help ease the symptoms of depression and is particularly helpful if you also have difficulty sleeping. It is thought to work by interfering with brain chemicals (called neurotransmitters) which may be involved in causing symptoms of depression.

The exact cause of depression is not known. It can develop for no apparent reason or it may be triggered by a life event such as a relationship problem, bereavement, or illness. With depression you have a consistently low mood and other symptoms severe enough to interfere with your normal day-to-day activities.

Who should not take doxepin?

Some 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 doxepin it is important that your doctor knows:

• Se você tem uma glândula tireoide hiperativa.

• If you have any problems with the way your liver works, or the way your kidneys work.

• If you have epilepsy or diabetes (diabetes mellitus).

• If you have porphyria - a rare inherited blood disorder.

• Se você estiver tomando outros medicamentos, incluindo aqueles disponíveis para compra sem receita, bem como medicamentos fitoterápicos e complementares. Isso é especialmente importante se você tomou recentemente um medicamento para depressão, conhecido como inibidor da monoamina oxidase (IMAO).

How to take doxepin capsules

• Read the manufacturer's printed information leaflet from inside the pack. It will give you more information about doxepin and will provide you with a full list of the side effects which you may experience from taking it.

• Doxepin can make you feel sleepy so your doctor may advise you to take a small dose when you first start taking it, and then to increase your dose gradually as your body gets used to it.

• Doxepin is often prescribed once a day at bedtime, although it can also be taken two or three times a day. Your doctor will tell you which is right for you and the directions will be printed on the label of the pack to remind you what the doctor has said.

  • If you have any questions about how to take the capsules, ask your pharmacist for advice.

• You can take doxepin before or after meals. Many people find if helps to swallow the capsule with a drink of water.

• If you forget to take a dose, take it as soon as you remember unless your next dose is due. If it is nearly time for your next dose, then take the next dose when it is due but leave out the forgotten dose. Do not take two doses together to make up for a missed dose.

Obtendo o máximo do seu tratamento

• Tente manter suas consultas regulares com seu médico. Isso é para que seu médico possa verificar seu progresso.

• You may feel that doxepin is not working for you straightaway. It can take a week or two for the effect to build up, and 4-6 weeks before you feel the full benefit. It is important that you do not stop taking it thinking that it is not helping.

• While 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 it straightaway.

• 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 doxepin as it increases the risk of side effects, such as feeling sleepy.

• There are several types of antidepressants - each type works in a slightly different way and can have different side effects. If you find that doxepin does not suit you then let your doctor know, as another antidepressant may be found that does.

• Some people who take doxepin find that their skin becomes more sensitive to sunlight than usual. Do not use sunbeds and try to avoid strong sunlight until you know how your skin reacts. Use a sun cream with a high sun protection factor.

• Your doctor may ask you to carry on taking doxepin even after you feel better. This is to help stop your symptoms from returning.

• If you buy any medicines, check with a pharmacist that they are suitable for you to take. This is because a number of medicines can increase the risk of side effects from doxepin, including some painkillers, flu remedies and antihistamines.

• If you have diabetes you may need to check your blood sugar (glucose) more frequently. This is because doxepin can alter the levels of sugar in your blood. Your doctor will advise you about this.

• If you are due to have any medical treatment, tell the person carrying out the treatment that you are taking a tricyclic antidepressant, as they can interfere with some anaesthetics.

• Continue to take doxepin 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 becomes necessary.

How to store doxepin capsules

• Mantenha todos os medicamentos fora do alcance e da vista das crianças.

Perguntas frequentes

Is doxepin better than Xanax?

Doxepin and Xanax (alprazolam) work in very different ways. Doxepin is a tricyclic antidepressant and Xanax is a benzodiazepine, mainly prescribed short-term for anxiety or panic, as it can cause dependence if used for too long. Which is “better” depends on your condition and medical history.
