Zaditor Eye Drops is an over-the-counter medication primarily used to relieve itchy eyes caused by allergies. It contains the active ingredient ketotifen, which is an antihistamine that works by blocking the release of histamine, a substance in the body that causes allergic symptoms such as itching and redness.

Zaditor Eye Drops are for ophthalmic (eye) use only and should be applied directly to the eye(s). The usual recommended dosage is one drop in the affected eye(s) twice a day, with at least 8 hours between doses. It's important to wash your hands before using the eye drops and avoid touching the tip of the dropper to prevent contamination.

Common side effects of Zaditor Eye Drops may include:

• Temporary stinging or burning sensation in the eyes after application
• Mild eye irritation
• Headache

Less common but more severe side effects may include:

• Eye pain
• Changes in vision
• Swelling or redness of the eye
• Signs of an allergic reaction, such as rash, itching, swelling, severe dizziness, or trouble breathing

If you experience any severe side effects or allergic reactions, stop using Zaditor Eye Drops immediately and seek medical attention.
