Exposure to pollen can cause your body to produce allergic symptoms, called hay fever. Cells in the linings of your nose and eyes release a chemical called histamine when they come into contact with pollen. Histamine causes inflammation (rhinitis), which produces symptoms such as sneezing and a runny or blocked nose. It also causes red, watery and itchy eyes (allergic conjunctivitis). Fexofenadine, an antihistamine, stops the effects of histamine and this helps to relieve these symptoms.

Urticaria is a condition where an itchy skin rash develops. The rash may be triggered by an allergy or it can be caused by some other factor which may not be known. If the rash lasts for longer than six weeks, it is referred to as chronic urticaria. Fexofenadine is given to ease the symptoms of rash in people with chronic urticaria.

There are three strengths of fexofenadine tablet available - 30 mg, 120 mg and 180 mg. The 30 mg strength is for treating hay fever in children aged 6-12 years; the 120 mg strength is for treating adults with hay fever; and the 180 mg strength is for chronic urticaria.

Fexofenadine 120 mg tablets can be bought from pharmacies for the treatment of hay fever symptoms. The pharmacist will need to ask questions to make sure this medicine is right for you.

Before taking fexofenadine

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 (or your child) start taking fexofenadine it is important that your doctor knows:

  • Si está embarazada, esperando un bebé o en período de lactancia.

  • Si toma o utiliza otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que pueda adquirirse sin receta, así como medicamentos a base de plantas y complementarios.

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

How to take fexofenadine

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

  • Recommended doses of fexofenadine are:

  • For adults with seasonal allergic rhinitis (hay fever): 120 mg taken once a day.

  • For children aged 6-12 years with seasonal allergic rhinitis (hay fever): 30 mg taken twice a day, in the morning and evening.

  • For adults with chronic urticaria: 180 mg taken once a day.

  • You should take fexofenadine before a meal where possible. Some people find it helps to swallow the tablet with a drink of water. Try to take the tablets at the same time of day each day, as this will help you to remember to take them.

  • If you do forget to take a dose, don't worry, but do remember to take your next dose when it is due. Do not take two doses together to make up for a forgotten dose.

  • Some antacids can reduce the amount of fexofenadine your body absorbs. Because of this, it is recommended that you do not take indigestion remedies during the two hours before or during the two hours after you take a fexofenadine tablet.

Aproveche al máximo su tratamiento

  • Many people only need to take an antihistamine when they have symptoms. Unless you are told otherwise, you should stop taking fexofenadine once your symptoms have eased.

  • Although fexofenadine is classed as a non-drowsy antihistamine, it can still cause drowsiness in a few people. If this happens to you, do not drive and do not use tools or machines.

  • If you drink alcohol while you are on fexofenadine, be aware of its effects on you and do not drink more than moderate amounts. Alcohol can increase the risk of side-effects from antihistamines.

  • Si va a someterse a una operación, a un tratamiento o a unas pruebas (sobre todo si es para detectar una alergia), no olvide decir que está tomando un antihistamínico.

  • Si compra algún medicamento, compruebe en la farmacia que es adecuado para tomarlo con un antihistamínico. Hay otros medicamentos que pueden aumentar el riesgo de efectos secundarios.
