Acrivastine for allergies

Overview

Acrivastine is a type of antihistamine used to relieve the symptoms of allergies such as hay fever and urticaria (hives).

You can buy acrivastine capsules without a prescription at pharmacies.

Acrivastine works by blocking the effects of histamine, a chemical released by the body during an allergic reaction.

This helps relieve symptoms such as sneezing, itching, watery eyes, and a runny nose caused by allergens such as pollen, pet dander, house dust mites, insect bites, and detergents.

Common side effects of acrivastine are:

• Feeling sleepy.

• Dry mouth.

You can 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.

Speak with your doctor or pharmacist if any side effects 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.

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.

• Read the leaflet before use. It explains how to take acrivastine and lists possible side effects.

• Take one capsule (8 mg) when needed. Adults and children over 12 years can take up to 3 capsules a day. Swallow the capsule with water, with or without food.

• If you miss a dose, skip it. Take your next dose when it is due. Do not take two doses together to make up for a missed 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.

• Keep all medicines out of the reach and sight of children.

• Store in a cool, dry place, away from direct heat and light.

Can I take acrivastine with other antihistamines?

Do not take acrivastine with other antihistamines unless advised by a doctor or pharmacist. Taking more than one antihistamine may increase the risk of side effects such as drowsiness.

Can I drink alcohol while taking acrivastine?

It is best to avoid or limit alcohol while taking acrivastine. Alcohol can increase feelings of drowsiness or dizziness in some people.

If you are pregnant, trying for a baby, or breastfeeding, speak to your doctor, pharmacist, or midwife before taking acrivastine. They can advise whether it is suitable for you.
