About mianserin
Tipo de medicamento | A tricyclic-related antidepressant |
Usado para | Depresión |
Disponible como | Tabletas |
Mianserin belongs to a group of medicines known as tricyclic-related antidepressants. Se prescribe para el tratamiento de depresión. La depresión puede desarrollarse sin una razón aparente, o puede ser desencadenada por un evento de la vida como un problema de relación, duelo o enfermedad. Las personas con depresión tienen un estado de ánimo consistentemente bajo y otros síntomas lo suficientemente graves como para interferir con las actividades normales del día a día.
Mianserin is thought to work by interfering with certain brain chemicals (called neurotransmitters) which may be involved in causing the symptoms of depression. It can be especially helpful if you are also having difficulty sleeping.
Before taking mianserin
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 mianserin it is important that your doctor knows:
Si estás embarazada o amamantando.
Si tienes una glándula tiroides hiperactiva.
If you have a problem with the way your liver works, or with the way your kidneys work.
If you have epilepsy or diabetes (diabetes mellitus).
Si has tenido problemas de estreñimiento.
Si tiene alguna dificultad para orinar, o si ha tenido problemas de próstata.
Si tienes un trastorno cardíaco o una enfermedad de los vasos sanguíneos.
Si alguna vez has tenido un problema de salud mental (en particular, trastorno bipolar o psicosis).
Si tienes presión elevada en los ojos, una condición llamada glaucoma.
Si le han dicho que tiene un tumor en la glándula suprarrenal, llamado feocromocitoma.
Si tienes un trastorno sanguíneo hereditario raro llamado porfiria.
If you are taking any other medicines, including those available to buy without a prescription, as well as herbal and complementary medicines. This is especially important if you have recently taken a medicine for depression, known as a monoamine-oxidase inhibitor (MAOI).
Si alguna vez has tenido una reacción alérgica a un medicamento.
How to take mianserin
Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about mianserin and will provide you with a full list of the side-effects which you may experience from taking it.
It is usual to be prescribed a dose of 30-40 mg daily to begin with. Your doctor may ask you to take this divided into several doses during the day, or as a single dose taken at bedtime. The directions for taking it will be printed on the label of the pack of tablets to remind you what the doctor said to you. As your body gets used to the new medicine, your dose may be increased. If you have any questions at any time about what dose to take, ask your pharmacist for advice.
Swallow mianserin tablets whole - do not crush, chew or break them. Many people find if helps to swallow the tablets with a drink of water. You can take mianserin before or after meals.
Si olvida tomar una dosis, tómela tan pronto como lo recuerde. Si cuando lo recuerda, ya es casi la hora de su próxima dosis, omita la dosis olvidada y tome la siguiente dosis cuando corresponda. No tome dos dosis juntas para compensar una dosis olvidada.
Obteniendo el máximo de tu tratamiento
Try to keep your regular appointments with your doctor. This is because your doctor will want you to have blood tests (especially during the first few months of treatment) and will want to check on your progress.
You may feel that the tablets are 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 the tablets thinking they are not helping. Also, 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.
There are several types of antidepressants - each type works in a slightly different way and can have different side-effects. If you find that mianserin does not suit you, then let your doctor know, as another antidepressant may be found that does.
Your doctor will recommend that you do not drink alcohol while you are on mianserin. This is because it increases the risk of side-effects, such as feeling sleepy.
Some people who take mianserin find that their skin becomes more sensitive than usual to sunlight. Try to avoid strong sunlight until you know how your skin reacts, or use a sun cream with a high sun protection factor. Do not use sunbeds.
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 mianserin, including some strong painkillers, flu remedies and antihistamines which can be bought from pharmacies.
If you have diabetes you may need to check your blood sugar (glucose) more frequently. This is because mianserin 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 mianserin, as it can interfere with some anaesthetics.
Continue to take mianserin until your doctor tells you otherwise. Stopping treatment suddenly can sometimes cause problems and your doctor may want you to reduce your dose gradually when this becomes necessary. Your doctor may ask you to carry on taking mianserin even after you feel better. This is to help stop your symptoms from returning.
