Zaditor Eye Drops Overview

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.

Side Effects of Zaditor Eye Drops

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.


Before using Zaditor Eye Drops, inform your doctor or pharmacist if you are allergic to ketotifen or any other medications. Also, inform them of your medical history, especially if you have any eye conditions or if you are pregnant or breastfeeding.

Avoid wearing contact lenses while using Zaditor Eye Drops unless directed otherwise by your doctor. If you wear contact lenses, remove them before using the eye drops and wait at least 10 minutes before reinserting them.

Do not drive or operate machinery if your vision is temporarily blurred after using Zaditor Eye Drops.

Keep the container tightly closed when not in use and store it at room temperature away from moisture and heat.

Can Zaditor Eye Drops be used in children?

I've been a Canadian Med Center customer for about 6 years now. In all that time there was never once that I considered taking my business elsewhere. They do a great job and the people they contract with are also super.

Always appreciate their prompt service but especially appreciate their hanging in there when there was difficulty getting my doctor to renew my prescription!
