A 35-year-old comes to the clinic. He states, Its 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 dont remember what they were. Can I have those things again? I just cant afford to miss work.

Please answer the following questions in a narrative format: 

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