Eye Allergy Remedy

Allergies are symptoms caused by the release of the chemical histamine in the body. They can be triggered by substances like mold, pollen or the proteins in certain foods. When allergies affect the eyes, symptoms like redness, itching and excessive tearing may be present. While prevention is best, prescription and over-the-counter products can help ease eye allergy symptoms once they've begun.

Eye Drops

• Over-the-counter (OTC) and prescription eye drops are the most common treatment for eye allergy symptoms. Most of these drops contain antihistamines and mast cell stabilizers that stop itch and prevent it from returning. They work by blocking histamine, a chemical responsible for causing most allergy symptoms.

  Zaditor (ketotifen) is one of the most effective over-the-counter options for eye allergy relief. It differs from other OTC eye drops in that it doesn't contain vasoconstrictors, which are known for causing rebound symptoms like redness and irritation. Medications including Optivar (azelastine) and Patanol (olopatadine) are available by prescription and work in a similar fashion.

Oral Antihistamines

• Antihistamines---both over-the-counter and prescription---provide yet another option for treating eye allergies. They work by competing with histamine for receptor sites, preventing the chemical from triggering symptoms like sneezing and itchy eyes.

  Over-the-counter medications like Claritin and Zyrtec are excellent options for treating allergy symptoms. They are less likely to cause unwanted side effects than sedating antihistamines and are comparable in potency and efficacy. Older antihistamines like Benadryl and Tavist can also be effective in treating eye allergies, but can sometimes cause sedation, depression and other side effects.

  Prescription antihistamines are similar to over-the-counter versions, but may be slightly more potent. Allegra, Phenergan, Atarax and Clarinex are among the most common prescription antihistamines. Antihistamines are most effective if taken continuously when allergies are the worst, such as during the spring and fall allergy seasons.

Herbal Remedies

• Many herbal and traditional remedies exist for treating eye allergies. The herb eyebright has been used for centuries as a remedy for eye inflammation. It contains tannins, which are likely responsible for its effects on inflammation. Eyebright can be applied directly to eyes in the form of drops or taken orally to fight allergic symptoms and irritation.

  Other common herbal remedies for eye allergies include chamomile, golden rod and dandelion, all of which can be taken internally as a tincture or tea. Herbs that reduce histamine production---such as reishi mushroom and stinging nettle---can also be useful in treating eye allergy symptoms.

Preventing Eye Allergies

• While herbs and medications can be helpful in reducing the symptoms of eye allergies, they are most effective when used in conjunction with preventive measures and general healthy lifestyle choices.

  Avoiding allergic triggers is the best method of prevention. According to the American College of Allergy, Asthma and Immunology (ACAAI), measures like staying indoors when pollen counts are highest can go a long way toward preventing allergies from becoming severe. Keep pets out of the bedroom and avoid leaving windows open to reduce pet dander, dust and pollen in the home. A dehumidifier can help reduce moisture levels in the air, which in turn cuts down on mold growth. Areas prone to high moisture, such as the bathroom, basement and kitchen, are all great places for dehumidifiers.
