About antazoline and xylometazoline eye drops

The drops contain two ingredients. Antazoline 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. Xylometazoline is a sympathomimetic agent; it works on the blood vessels in the eye to reduce redness. Antazoline and xylometazoline eye drops (brand name Otrivine-Antistin®) are used to treat conjuntivite alérgica.

Allergic conjunctivitis causes red, watery and 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 rinite alérgica season. Perennial allergic conjunctivitis persists throughout the year. This is commonly due to an allergy to house dust mite or animal hair. Antazoline and xylometazoline eye drops are available on prescription, or you can buy them without a prescription at a pharmacy. They can be used by adults and by children over 12 years of age.

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

• Se você usa lentes de contato gelatinosas.

• If you have any of the following: high blood pressure, an overactive thyroid gland, diabetes, increased pressure in your eye (glaucoma), heart or blood vessel disease, difficulty passing urine, or a tumour on your adrenal glands, called phaeochromocytoma.

• Se você está grávida ou amamentando. Isso porque, enquanto estiver esperando ou alimentando um bebê, você deve usar medicamentos apenas sob recomendação de um médico.

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

• Se você estiver tomando ou usando qualquer outro medicamento. Isso inclui quaisquer medicamentos que você esteja tomando e que estejam disponíveis para compra sem receita médica, bem como medicamentos fitoterápicos e complementares.

1. Lave bem as mãos antes de usar as gotas.

2. Remova a tampa.

3. Incline a cabeça um pouco para trás e puxe a pálpebra inferior do olho para formar uma bolsa.

4. Segure o frasco de cabeça para baixo perto do seu olho. Tente não tocar no seu olho enquanto faz isso.

5. Aperte suavemente a garrafa para liberar uma gota no seu olho. Use uma segunda gota apenas se a primeira não entrar no seu olho.

6. Feche o olho por um ou dois minutos e pressione suavemente o lado do nariz onde o canto do olho encontra o nariz. Isso ajuda a evitar que a gota escorra e a mantém no olho.

7. Repita o processo no outro olho.

8. Recoloque a tampa.

• 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 will provide you with a full list of the side-effects which you may experience from using them.

• Use the eye drops two or three times a day in both eyes, unless you have been told otherwise by your doctor.

• 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.

• When you first put the drops 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 using machines or tools.

• 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.

• 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.

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

• Your doctor will tell you how long to use the drops for. You should notice an improvement in your symptoms within a few days, but treatment for up to seven days is sometimes required. Do not use the drops for more than seven consecutive days.

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 antazoline and xylometazoline eye drops. You will find a full list in the manufacturer's information leaflet supplied with your drops. Unwanted effects often improve as your body adjusts to a new medicine, but speak with your doctor or pharmacist if the following continues or becomes 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.

• Mantenha todos os medicamentos fora do alcance e da vista das crianças.

• Armazene em local fresco e seco, longe de calor e luz diretos.

• Eye drops only keep for four weeks once the bottle has been opened so throw away the bottle after you have finished the course of treatment, even if there is some solution left. Never keep opened bottles of eye drops to use later. This helps to prevent the risk of eye infections.
