Alcaftadine belongs to the class of medicines known as H1 antihistamines. It is used to prevent and treat symptoms of eye allergies such as itching, redness, irritation or burning sensation.

Before using Alcaftadine, you should tell your doctor if you are allergic to Alcaftadine or any of its ingredients to avoid any allergic reactions. Let your doctor know if you have, or have had any problems with your eyes. Inform your doctor about all the other medicines you are taking because they may affect, or be affected by, this medicine. Inform your doctor if you are pregnant, planning to conceive or breastfeeding to prevent any harmful effects on the baby. Do not use this medicine to treat irritation caused by wearing contact lenses or while wearing contact lenses. This is because Alcaftadine can cause discoloration of the soft lenses.

Alcaftadine works by blocking the release of a naturally occuring substance in our body known as histamine, that is responsible for producing symptoms of allergies such as itching, watery eyes, redness and irritation in the eyes.

Remember to wash your hands before and after application of Alcaftadine. Do not touch the eye with the dropper or the tip of the ointment tube. Try to use it at about the same time each day. Use the prescribed number of drops or the right amount of ointment. Do not use more medicine than directed and do not use more often than directed. Do not stop using Alcaftadine unless directed by your doctor and try not to miss any doses.

If you wear soft contact lenses, remove them before using Alcaftadine and wait at least 15 minutes before putting your lenses back in. Do not touch the tip to any surface, or to your eye, to avoid contamination.
