Drug therapy for ocular allergy.

Ocular allergy is a common problem for the primary care practitioner. A range of ocular decongestants, antihistamines, mast cell stabilizers, and corticosteroids are available for use, and practitioners must be familiar with the clinical effectiveness, treatment regimens, and side effects of these drugs. This paper reviews the drugs, both prescription and nonprescription, appropriate for management of ocular allergy and provides guidelines for their use.
