What is it?

Zaditor is a first‑generation antihistamine eye drop that blocks histamine receptors in the eye, relieving itching, redness, and watery discharge caused by allergic conjunctivitis (e.g., hay fever, pollen, pet dander). The 0.025 % concentration is the most common strength for over‑the‑counter (OTC) use in the U.S. and many other countries.

How do I use it?

Step	Instructions
1.	Wash your hands thoroughly.
2.	Tilt your head back slightly and look upward.
3.	Gently pull down the lower eyelid to create a small pocket.
4.	Hold the dropper above the eye, squeeze one drop into the pocket, then close your eye.
5.	Avoid rubbing the eye. If you use a contact lens, remove it before administering the drops and wait at least 15 minutes before reinserting.

• Typical dosing: 1 drop in each eye, 2–3 times daily (every 8–12 hours).
• First‑time users: Some people notice a brief burning or stinging sensation. This usually passes within a minute.
• Maximum frequency: Never exceed 3–4 doses in 24 hours unless a doctor says otherwise.

Who should use it?

• Adults, children, and infants ≥ 6 months (in the U.S.; check local regulations for age limits).
• People with non‑allergic eye irritation (dry eye, infection) should use a different treatment.
• Pregnancy & breastfeeding: Consult your healthcare provider. The drug is classified as pregnancy category B in the U.S., but data are limited.
