Sir, when i don t sleep in the night, automatically i have sneezing problems. Once sneezing comes immediately, i have a feeling that i have the throat infection and my face becomes dry. This happening to very often. Some times, Due to Dust also, i find this same complaint. Doctor recommends always Either Allegra or Montek Lc. I take these medicine only when i have sneezing problems otherwise don t take. Pl suggest Regards N.Balachandran Chennai -87 0000 0000
