Allergic Rhinitis
"Have terrible post nasal drip. Claritan is the only thing that works. No generics as good. Do find that the med works half the time it says it does;12 hr works for 6, 24 ? About 8. I take 12 hr twice a day in spring and fall. Deal with the hrs it&#039;s not working. Doesn&#039;t interfere with my sleep."
