Alimemazine

About alimemazine

Alimemazine is used to relieve lumpy and itchy allergic skin reactions called hives (urticaria). It is also used before surgical procedures to help keep young children calm.

Alimemazine, an antihistamínico, works by blocking a substance called histamine in the body. In some people, an excess of histamine is produced by exposure to substances such as pollen, pet fur, house dust or insect bites, and this causes reacciones alérgicas en la piel. By blocking histamine, alimemazine eases the itchiness and lumpiness of these reactions.

When alimemazine is prescribed for a young child who is about to have an operation, it produces a sedative effect which helps the child feel relaxed. Alimemazine is not suitable for children under 2 years of age.

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 alimemazine it is important that your doctor or pharmacist knows:

• Si estás embarazada, intentando tener un bebé o amamantando.

• Si tienes una afección cardíaca o enfermedad de los vasos sanguíneos.

• Si tienes problemas de hígado, riñón o próstata.

• If you have any difficulties passing urine or if you have been constipated for some time.

• Si tienes problemas para respirar.

• If you have any of the following: epilepsy, Parkinson's disease, depression, increased pressure in your eyes (glaucoma), or a condition called myasthenia gravis which causes muscle weakness.

• Si alguna vez ha tenido amarillamiento de la piel o del blanco de los ojos (ictericia) o un trastorno sanguíneo.

• If you have low levels of thyroid hormone (hypothyroidism).

• If you have a tumour on your adrenal gland (phaeochromocytoma).

• Si tienes un trastorno sanguíneo hereditario raro llamado porfiria.

• Si está tomando o usando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que esté disponible para comprar sin receta, así como medicamentos herbales y complementarios.

• Si alguna vez ha tenido una reacción alérgica a otro antihistamínico, o a cualquier otro medicamento.

• Before you start this treatment, read the manufacturer's printed information leaflet from inside your pack. The manufacturer's leaflet will give you more information about alimemazine and a full list of side-effects which you may experience from taking it.

• Take alimemazine exactly as your doctor tells you to. This information will be printed on the label of the pack you have been supplied with to remind you. The usual recommended doses for allergic skin reactions are:
  

  • For adults and children aged 12 years or over: 10 mg taken 2 or 3 times a day (it may be less than this if you are over 65 years of age).

  • For children 5-11 years of age: 5 mg taken 3 or 4 times daily.

  • For children 2-4 years of age: 2.5 mg taken 3 or 4 times daily.

• If you are giving alimemazine liquid medicine to a child, make sure you follow the dosing instructions on the bottle carefully so that you measure out the correct dose.

• You can take alimemazine before or after meals. Some people find it helps to swallow the tablets with a drink of water.

• Si olvida tomar una dosis, no se preocupe, simplemente tome la siguiente dosis cuando corresponda y luego continúe como antes. No tome dos dosis juntas para compensar una dosis olvidada.

• Alimemazine causes drowsiness. If you feel drowsy or sleepy, do not drive and do not use tools or machines.

• Do not drink alcohol while you are on alimemazine as it increases the chance you will feel sleepy.

• Alimemazine may cause your skin to become more sensitive than normal to sunlight. Use a sunscreen that protects against UVA light and has a sun protection factor (SPF) of at least 15, especially in strong sunlight or until you know how your skin reacts. Do not use sunbeds.

• If you buy any medicines, check with a pharmacist that they are suitable to take with alimemazine. This is because a number of other medicines can interfere with the way alimemazine works or can increase the risk of side-effects.

• If you are having an operation or any dental treatment, tell the person carrying out the treatment that you are taking alimemazine.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with alimemazine, particularly when it is taken over a period of time. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

Si experimenta otros síntomas que cree que pueden deberse a este medicamento, hable con su médico o farmacéutico.
