About antazoline and xylometazoline eye drops

Type of medicine

Anti-allergy eye drops

Used for

To relieve the eye symptoms of allergies such as hay fever

Also called


Available as

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 allergic conjunctivitis.

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 hay fever 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.

Before using antazoline and xylometazoline eye drops

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:

  • If you wear soft contact lenses.

  • 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.

  • If you are pregnant or breastfeeding. This is because, while you are expecting or feeding a baby, you should only use medicines on the recommendation of a doctor.

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

  • If 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.

How to use antazoline and xylometazoline eye drops

  1. Wash your hands well before you use the drops.

  2. Remove the cap.

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

  4. Hold the bottle upside down near to your eye. Try not to touch your eye as you do this.

  5. Gently squeeze the bottle to release one drop into your eye. Only use a second drop if the first drop missed going into your eye.

  6. Close your eye for a minute or two, and press gently on the side of your nose where the corner of your eye meets your nose. This helps to stop the drop from draining away and keeps it in your eye.

  7. Repeat the process in your other eye.

  8. Replace the cap.

Getting the most from your treatment

  • 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.
