HOME CARE ADVICE FOR EYE ALLERGY

  1. Wash Allergens Off the Face:

    • Use a wet washcloth to clean off the eyelids and surrounding face.

    • Rinse the eyes with a small amount of warm water (tears will do the rest).

    • Then apply a cold wet washcloth to the itchy eye.

    • Wash the hair every night because it collects lots of pollen.

  2. Oral Antihistamines:

    • If the nose is also itchy and runny, your child probably has hay fever (i.e., allergic symptoms of the nose AND eyes).

    • Give your child an oral antihistamine, which should relieve the nose and the eye symptoms.

    • Oral antihistamines usually control the eye symptoms and avoid the need for eye drops.

    • Benadryl or Chlorpheniramine (CTM) products are very effective (no prescription needed). They need to be given every 6 to 8 hours (See Dosage table). The bedtime dosage is especially important for healing the lining of the nose.

    • Continue oral antihistamines every day until pollen season is over (usually 2 months for each pollen).

  3. New Antihistamine Eye Drops (Ketotifen) for Pollen Allergies - 1st Choice:

    • Usually an oral antihistamine will adequately control the allergic symptoms of the eye.

    • If the eyes remain itchy and poorly controlled, buy some Ketotifen antihistamine eyedrops (no prescription needed).

    • Dosage: 1 drop every 12 hours

    • Ask your pharmacist to recommend a brand (e.g. Zaditor or Alaway)

    • For severe allergies, the continuous use of ketotifen eye drops on a daily basis during pollen season will give the best control.

  4. Older Antihistamine/Vasoconstrictor Eye Drops - 2nd Choice:

    • Usually the eyes will feel much better after the allergic substance is washed out and cold compresses are applied.

    • If not, this type of eye drop can be used for intermittent eye allergy symptoms (no prescription needed).

    • Ask your pharmacist to recommend a brand. Examples are Naphcon A, Opcon A or Visine A.

    • Avoid vasoconstrictor eyedrops without an antihistamine (without an A in the name). Reason: they only treat the redness, not the cause.

    • Dosage: 1 drop every 8 hours as necessary.

    • Avoid continuous use for over 5 days. (Reason: rebound red eyes)

    • Disadvantage: less effective than Ketotifen eye drops.

  5. Contacts: Some children with contact lenses may need to switch to glasses temporarily (Reason: to permit faster healing).

  6. Expected Course: If the allergic substance can be identified and avoided (e.g., a cat), the symptoms will not recur. Most eye allergies continue through the pollen season (4 to 8 weeks).

  7. Call Your Doctor If:

    • Itchy eyes aren't controlled in 2 days with continuous allergy treatment

    • Your child becomes worse

And remember, contact your doctor if your child develops any of the "Call Your Doctor" symptoms.
