Acrivastine for allergies

About acrivastine

Acrivastine belongs to a group of medicines called antihistamines - it is an anti-allergy medicine. It stops the effects of a naturally occurring substance called histamine and this helps to relieve the symptoms of allergies such as hay fever and urticaria.

Exposure to substances such as pollen, pet fur, house dust or insect bites can cause your body to produce allergic symptoms. Cells in the lining of your nose and eyes release histamine when they come into contact with these substances. This leads to inflammation in your nose and eyes, which produces symptoms such as sneezing and watery eyes.

Urticaria is a condition where an itchy skin rash develops. The rash can be triggered by an allergy to a substance such as a soap or a detergent.

You can buy acrivastine capsules without a prescription at pharmacies.

To make sure that this is the right treatment for you, before you start taking acrivastine 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 (because the safety of acrivastine has not been studied in people in this age group).

• You have any problems with the way your kidneys work.

• You have epilepsy.

• You have a rare inherited blood disorder called porphyria.

• You are taking or using any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.

• You have ever had an allergic reaction to another antihistamine, or to any other medicine.

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

• The dose recommended for adults and for children aged over 12 years, is one (8 mg) capsule taken as needed up to three times a day. You can take the capsule either with or without food. The capsule is best swallowed with a drink of water.

• If you forget to take a dose, don't worry, just take the next dose when it is due and then continue as before. Do not take two doses together to make up for a forgotten dose.
  

• Most people only need to take an antihistamine when they have symptoms. You should stop taking the capsules once your symptoms have eased.

• Although acrivastine 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 while affected by drowsiness.

• If you drink alcohol while you are on acrivastine, 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.

• If you are having an operation, or any treatment or tests (particularly if it is to test for an allergy), make sure you say that you are taking an antihistamine.

• If you buy any other medicines 'over the counter', check with a pharmacist that they are suitable to take with an antihistamine. This is because a number of other medicines can increase the risk of side-effects.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the more common ones associated with acrivastine. The best place to find a full list of the side-effects which can be associated with your medicine, is from the manufacturer's printed information leaflet supplied with the medicine. Alternatively, you can find an example of a manufacturer's information leaflet in the reference section below. Speak with your doctor or pharmacist if any of the following continue or become troublesome.

If you experience any other symptoms which you think may be due to the capsules, speak with your pharmacist for further advice.
