sinusitis
"This is the ONLY sinus/allergy medication that worked consistently for me.  My doctor prescribed the Deconamine SR, which has a sustained release of 12 hrs.  FINALLY, after years of trying all the other prescription antihistamines/decongestants, when I took this, I could wake up without a sore throat from drainage, or dry mouth from over-zealous decongestants.  It worked like a charm!  "
