Azelastine eye drops for allergies

About azelastine eye drops

Conjuntivitis alérgica causes red, watery, itchy eyes. It is caused by exposure to irritants such as plant pollens, pet fur, cosmetics or house dust mite. Seasonal allergic conjunctivitis occurs at certain times in a year, a common cause being an allergy to pollen in the hay fever season. Perennial allergic conjunctivitis persists throughout the year. This is commonly due to an allergy to house dust mite or animal hair.

Azelastine is an antihistamine; it helps relieve allergic itchiness by blocking the release of a chemical called histamine, which is produced by the body as part of an allergic reaction.

To make sure this is the right treatment for you, before you start using the eye drops it is important that your doctor knows:

• Si usas lentes de contacto blandos.

• If you are pregnant or breastfeeding. (Although azelastine is not known to be harmful to babies, it is still important that you tell your doctor if you are expecting or breastfeeding a baby.)

• If you have ever had an allergic reaction to an antihistamine, or to any other eye drops.

1. Lávese las manos antes de usar las gotas.

2. Retire la tapa.

3. Tilt your head back a little, and then pull the lower lid of your eye out to form a pocket between your eye and the lower eyelid.

4. Sostén la botella boca abajo cerca de tu ojo. Intenta no tocar tu ojo mientras haces esto.

5. Apply sufficient pressure to the bottle to release one drop into your eye. Only use a second drop if the first drop missed going into your eye.

6. Cierra el ojo durante uno o dos minutos y presiona suavemente el lado de tu nariz donde la esquina de tu ojo se encuentra con tu nariz. Esto ayuda a evitar que la gota se drene y la mantiene en tu ojo.

7. Repeat the process in your other eye.

8. Coloca de nuevo la tapa.

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

• Azelastine eye drops should usually be used twice a day (in the morning and the evening). If your symptoms are particularly severe, your doctor may suggest you use them up to four times a day.

• When you first put the drop into your eye, it may cause blurred vision. This should quickly clear, but make sure you can see clearly again before you drive and before you use machines or tools.

• Take care not to touch your eye, fingers, or any other surface with the dropper of the bottle. This could infect the liquid left in the bottle.

• If you are using any other eye drops, leave 5-10 minutes between using the other eye drops. This is to prevent more liquid going into your eye than it can handle. Otherwise the drops will overflow from your eye and not have the intended effect.

• Your doctor will tell you how long to use the drops for. You should not use the drops for a period of more than six consecutive weeks.

• If your symptoms do not improve within two days, or if they become worse, make another appointment to see a doctor.

• Do not wear soft contact lenses while you are using the eye drops, unless your doctor has advised you otherwise. This is because lenses will irritate your eyes, and also because there is a preservative in the drops which can affect soft contact lenses.

Along with their useful effects, eye drops can cause unwanted side-effects although not everyone experiences them. The table below contains the most common one associated with azelastine eye drops. The best place to find a full list of the side-effects which can be associated with azelastine is from the manufacturer's printed information supplied with the drops. 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.

Occasionally people can be allergic to eye drops, particularly when the eye drops contain a preservative. If you notice a rash around your eyes, or any swelling or increased itching, stop using the drops and contact a doctor for advice. If you experience any other symptoms which you think may be due to the eye drops, speak with your doctor or pharmacist for further advice.

• Mantenga todos los medicamentos fuera del alcance y la vista de los niños.

• Almacenar en un lugar fresco y seco, lejos del calor y la luz directos.

• Eye drops only keep for four weeks once the bottle has been opened - do not use the drops if the bottle has been open for longer than this. This helps to prevent the risk of eye infections.
