How Azelastine Eye Drops works

Azelastine is an antihistamine that blocks the effects of histamine and other substances released by the body during an allergic reaction, which reduces eye inflammation, itching, redness, and watering.

Azelastine Eye Drops dosage

Only use this medicine in the eyes; do not swallow it. Wash your hands before applying the drops, and avoid letting the dropper tip touch your eye, fingers, or any surface to prevent contamination.

Remove soft contact lenses before use and wait at least 15 minutes before putting them back in. If you use other eye drops, space them out from this medicine.

You may use the drops before going outside if you expect contact with pollen. Use regularly until symptoms go away, as stopping early may cause symptoms to return.

If you forget a dose, use it as soon as you remember, then continue at the usual time; do not double up. Talk to a doctor if you do not feel better, or feel worse, after 2 days. Do not use for longer than 6 weeks unless your doctor tells you to.
