About hydroxyzine

Usado para

Itching, urticaria

Hydroxyzine belongs to a group of medicines known as sedating los antihistamínicos. It is used to relieve itching caused by some skin conditions, such as nettle rash (urticaria).

Exposure to substances such as pollen, pet fur, house dust or insect bites can cause some people to produce an excess of a chemical called histamine. This release of histamine can then cause a skin rash and/or itchiness. Because hydroxyzine blocks the effects of histamine, it helps relieve symptoms like these.

To make sure that this is the right treatment for you, before you start taking hydroxyzine it is important that you discuss the treatment with a doctor or pharmacist if:

  • You are pregnant, trying for a baby or breastfeeding.

  • You are over 65 years of age. This is because you could be more susceptible to side-effects.

  • You have a problem with the way your liver works, or if you have a problem with your kidneys.

  • You have a condition which causes increased pressure in your eyes, such as glaucoma.

  • Tienes problemas de próstata, o si has estado experimentando alguna dificultad para orinar.

  • You know you have an unusual heart rhythm.

  • Sabes que tienes una obstrucción en tus intestinos delgados.

  • Tiene epilepsia.

  • You have any long-term breathing problems, such as asthma or bronchitis.

  • You have a rare inherited blood condition known as porphyria.

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

  • You have ever had an allergic reaction to a medicine.

  • 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 hydroxyzine and will provide a full list of the side-effects which you may experience from taking it.

  • Take hydroxyzine exactly as your doctor tells you to. Usually, it is sufficient to take one dose at night to control symptoms. Where this is not the case, you may be asked to take 2 or 3 doses during the day in addition to your dose at night.

  • You can take hydroxyzine before or after food. 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.

  • Most people only need to take an antihistamine for a short while when they have symptoms. You should stop taking hydroxyzine once your symptoms have eased.

  • Hydroxyzine can cause drowsiness. If this happens to you, do not drive and do not use tools or machines. Alcohol will make the drowsiness worse, so it is best not to drink alcohol while you are on hydroxyzine.

  • If you are having an operation or any treatment or tests (particularly if it is to test for an allergy), tell the person due to carry out the treatment that you are taking an antihistamine. This is because you may be advised to stop taking hydroxyzine for a short while before some allergy tests.

  • Hydroxyzine may cause some people's skin to become more sensitive to sunlight than normal. 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 safe to take with an antihistamine. This is because a number of other medicines can interfere with the way hydroxyzine works and can increase the risk of side-effects.
