eatnow,
It took me years to find the combinations that worked for me. Don't give in too quickly.
With Flonase, I use two sprays in each nostril once a day--in the morning.
With Astelin, I use two sprays in each nostril two times a day.
I use the Xlear two or three times a day. (Used to use Ayr.)
Are you in a humid climate? If not, a humidifier might also help. It is a catch 22 for me because I am allergic to the molds, but there are times I REALLY need the humidifier because the humidity where I live is extremely low. I am just careful to wash it often and change the filters regularly.
I take Allegra and Singulair for allergies. I also use dry eye drops and Restasis for Chronic Dry Eye. With the dry air and high altitude, there are a lot of people in my area with Chronic Dry Eye as well as dry nasal passages.
If you have questions about the meds before your next doctor's appointment, try talking to your Pharmacist. Mine is particularly helpful in answering questions about any side effects for over the counter items as well as prescriptions.
