A 35-year-old comes to the  clinic. He states, “It’s getting close to allergy season and I need  something to keep me from getting sick. Last year the doc gave me a  shot, a spray, some pills, and an inhaler. They worked really  well but I  don’t remember what they were. Can I have those things again? I just  can’t afford to miss work.”
Please answer the following questions in a narrative format: 

Discuss the epidemiology of allergies.
What are your treatment options (consider pharmacoeconomic)? Compare first and second-generation antihistamines.
What education will you provide to the patient?
