HOME CARE ADVICE FOR EYE ALLERGY
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.
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 and over-the-counter. 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).
New Antihistamine Eye drops (Ketotifen) for Pollen Allergies OTC (over-the-counter) - 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 OTC antihistamine eyedrops.
- Ketotifen eyedrops (OTC) are a safe and effective new product. (2007)
- 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.
Older Antihistamine/Vasoconstrictor Eye Drops (OTC) - 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.
- Dosage: 1 drop every 8 hours as necessary.
Contacts: Some children with contact lenses may need to switch to glasses temporarily (Reason: to permit faster healing).
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).
Call Your Doctor If:
- Itchy eyes aren't controlled in 2 days with continuous allergy treatment
- Your child becomes worse
