Alocril Eye Drops: Uses, Dosage, Side Effects, Precautions and Alternates product

Quick overview

Alocril (nedocromil) is a mast cell stabilizer eye drop used to treat itching caused by allergic conjunctivitis. It works by preventing certain eye cells from releasing chemicals that trigger allergic symptoms such as itching, redness, watering, and burning. It is available as an ophthalmic solution and is used regularly throughout the allergy season as directed by a doctor.

What is Alocril Eye Drops

Alocril (nedocromil) ophthalmic solution is a mast cell stabilizer, which is an anti-allergic medication, used to treat eye symptoms of allergic conditions, such as inflammation, itching, watering, and burning.

Alocril Eye Drops uses

  • Treatment of itching associated with allergic conjunctivitis (eye allergies)

Benefits of Alocril Eye Drops

  • Helps relieve itchy eyes caused by allergies.
  • Helps reduce redness and irritation from allergic conjunctivitis.
  • Can help control watery eyes and burning discomfort related to allergies.
  • Helps prevent and control recurrent allergic eye symptoms when used as prescribed.

How Alocril Eye Drops works

Alocril works by stopping certain cells in your eye from releasing chemicals that cause allergic symptoms like itching and redness. It blocks the release of these chemicals from mast cells, which are involved in allergic reactions.

Alocril Eye Drops dosage

Use the eye drops regularly, as directed by your doctor, at evenly spaced times each day. Start using the drops as close as possible to the start of your allergy symptoms, and keep using them throughout your allergy season, even if your symptoms go away.

Wash your hands thoroughly before and after using the drops. Tilt your head back, gently pull down your lower eyelid, and look up before placing the drop. Avoid letting the dropper tip touch your eye, eyelid, fingers, or any other surface, and avoid placing the drops directly on the cornea (the clear area over the pupil); place them just inside the lower eyelid instead. Blink a few times after the drop goes in so it spreads over the eye, then close your eyes and wipe away any extra solution with a clean tissue.

Do not wear soft contact lenses while using this medicine; if you wear hard or gas-permeable lenses, take them out before using the drops and wait at least 5 minutes before putting them back in. Do not use other eye medications at the same time without checking with your doctor first; if you do use another eye medicine, wait about 5 minutes between drops.

If you miss a dose, use it as soon as you remember, unless it is almost time for your next dose — do not double up on drops. This medicine has not been shown to be safe or effective for children under 3 years old.
