Allergic Rhinitis

Abstract
A Baltimore college student has rhinorrhea, sneezing, nasal congestion, and itchy, watery eyes in the spring. He reports having had similar symptoms the previous spring. Over-the-counter allergy pills failed to help his symptoms and caused dry mouth and somnolence. He wants relief and assurance that he won't be ill, have dry mouth, or feel drowsy during final exams. On examination, his conjunctivae are injected, and his nasal mucous membranes are pale, wet, and boggy. What should the physician recommend?
