Azelastine drops relieve eye itching and redness associated with allergies.
It is usual to use the drops twice each day, although they can be used up to four times a day for severe symptoms.
When first put in, eye drops can cause blurred vision. Wait until this clears before you drive and before you use tools or machines.

About azelastine eye drops
Tipo de medicamento | Antihistamine eye drops |
Utilizado para | To relieve the symptoms of allergic conjunctivitis |
También llamado | Optilast® |
Disponible como | Gotas oculares |
Allergic conjunctivitis 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.
Before using azelastine eye drops
Para asegurarse de que éste es el tratamiento adecuado para usted, antes de empezar a usar el colirio es importante que su médico lo sepa:
Si usa lentes de contacto blandas.
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.

How to use azelastine eye drops
Lávese las manos antes de utilizar las gotas.
Quita la tapa.
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.
Sostenga la botella boca abajo cerca del ojo. Procure no tocarse el ojo mientras lo hace.
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.
Cierre el ojo durante uno o dos minutos y presione suavemente en el lado de la nariz donde el rabillo del ojo se une con la nariz. Esto ayuda a evitar que la gota se escurra y la mantiene en el ojo.
Repeat the process in your other eye.
Vuelva a colocar la tapa.
Aproveche al máximo su tratamiento
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.
Tenga cuidado de no tocarse el ojo, los dedos o cualquier otra superficie con el cuentagotas de la botella. Esto podría infectar el líquido que queda en el frasco.
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.

How to store azelastine eye drops
Mantenga todos los medicamentos fuera del alcance y de 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.
