Talking to your health care provider

To get the most out of your visit with your health care provider, be prepared. Most health care providers are very busy, so to make the most of your time together, think about the questions you have, and the information your health care provider may need from you in advance.

Whether this is your first visit or a regular checkup, be ready to discuss your nasal allergies and overall health. For example, make a list of the nasal allergy symptoms you're experiencing and what triggers them (if you know), the types and dosages of prescription and over-the-counter medicines you take for your nasal allergies and other conditions, and any changes to your medical history since your last visit.
