What is doxepin used for?
Retour au sommaireDoxepin is used for the treatment of dépression. It belongs to a group of medicines called antidépresseurs tricycliques.
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?
Retour au sommaireSome 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:
Si vous êtes enceinte ou si vous allaitez.
Si vous avez une glande thyroïde hyperactive.
Si vous avez des problèmes avec le fonctionnement de votre foie ou de vos reins.
If you have epilepsy or diabetes (diabetes mellitus).
If you have had problems with constipation over a long time.
Si vous avez des difficultés à uriner, ou si vous avez eu des problèmes de prostate.
Si vous avez un trouble cardiaque ou une maladie des vaisseaux sanguins.
If you have had a mental health problem - in particular, bipolar disorder or psychosis.
If you have increased pressure in your eyes (glaucoma).
If you have been told you have phaeochromocytoma - a tumour on your adrenal gland.
If you have porphyria - a rare inherited blood disorder.
Si vous prenez d'autres médicaments, y compris ceux disponibles à l'achat sans ordonnance, ainsi que des médicaments à base de plantes et complémentaires. Cela est particulièrement important si vous avez récemment pris un médicament pour la dépression, connu sous le nom d'inhibiteur de la monoamine-oxydase (IMAO).
Si vous avez déjà eu une réaction allergique à un médicament.
How to take doxepin capsules
Retour au sommaireRead 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.
Tirer le meilleur parti de votre traitement

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.

Questions fréquemment posées
Retour au sommaireCan you get doxepin in the UK?
Yes, doxepin is available in the UK, but it’s not commonly prescribed compared to newer antidepressants. It may be used for depression, anxiety, or sometimes for sleep problems, but usually only when other options haven’t worked.
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.
How effective is doxepin for sleep?
Doxepin at low doses is sometimes prescribed to help with insomnia as it might improve sleep quality by reducing how often you wake up during the night and helping you stay asleep longer. It’s generally considered effective, especially for people who have trouble staying asleep, but it may not work for everyone.

Questions fréquemment posées
How does doxepin work to treat depression?
Doxepin is a tricyclic antidepressant thought to work by interfering with brain chemicals called neurotransmitters. These neurotransmitters are believed to be involved in causing the symptoms of depression.
Can I take doxepin with other medications?
You should tell your doctor about all other medicines you are taking, including those bought without a prescription, as well as herbal and complementary medicines. This is particularly important if you have recently taken a monoamine-oxidase inhibitor (MAOI) for depression, or any medicines that can increase the risk of side effects from doxepin, such as some painkillers, flu remedies, and antihistamines.
How long will it take for doxepin to start working?
You may not feel the effects of doxepin straight away. It can take one to two weeks for the effect to build up, and typically four to six weeks before you experience the full benefit. It's important not to stop taking it prematurely, thinking it's not helping.
What should I do if I forget to take a dose of doxepin?
If you forget a dose, take it as soon as you remember. However, if it's almost time for your next scheduled dose, then simply take the next dose when it's due and skip the forgotten one. Do not take two doses at once to compensate for a missed dose.
Why might my doctor ask me to continue taking doxepin even after my symptoms improve?
Your doctor might advise you to continue taking doxepin even after you feel better. This is a common practice with antidepressants and helps to prevent your depression symptoms from returning.
Can doxepin make my skin more sensitive to the sun?
Yes, some people who take doxepin find their skin becomes more sensitive to sunlight. To protect your skin, it's advised to avoid strong sunlight and not use sunbeds until you understand how your skin reacts. Using a sun cream with a high sun protection factor is also recommended.
What is 'serotonin syndrome' and what should I do if I suspect it?
Serotonin syndrome is a rare but serious condition where levels of serotonin in the brain become too high, often due to taking more than one medicine that affects serotonin. You should seek medical attention immediately if you experience a combination of stiff muscles or 'jerky' movements, an unusually fast heartbeat, high temperature (fever), feeling or being sick, diarrhoea, feeling delirious, or seeing visions (hallucinating).
