Q: I've done everything that you suggested, but I'm still itching and uncomfortable. How can we treat this?
A: Cold compresses can help with the swelling and may provide a little anesthesia if cold enough, but eye drops are the mainstay of treatment.
Oral antihistamines were among the first systemic drugs to treat allergies and can still be used successfully. Newer antihistamines such as Claritin or Zyrtec are effective and won't cause drowsiness.
"Older" eye drops include antihistamine/decongestant combinations. There are also mast cell stabilizers that prevent release of histamine, and also dual action antihistamines and mast cell stabilizers.
If you're still suffering, an ophthalmologist may carefully prescribe low doses of topical steroids for short periods of time. Steroid use needs to be monitored since prolonged use can cause glaucoma and cataracts.
