sinusitis
"2 Years ago I thought I had a toothache...after a visit to the dentist, he told me it was a sinus infection and to go to the nearest medical centre.  I did and they prescribed me this drug.  After two days I had to call 911 from vomiting and passing out .  The only thing that saved me was Clariton Extra Strength to dry me up finally .. relief was within 20 minutes from taking only 1 pill ... true true story."
