How can i reduce/get rid of postnasal drip?

Probable allergies: would use antihisamines like claritan or Zyrtec, would also use Fluticasone nasal spray if chronic problem consistent with allergies

Postnasal Drip: Every day, glands in the linings of your nose make about a quart of mucus each day. The excess can come out of the nostrils -- that’s a runny nose. When the mucus runs down the back of your nose to your throat, it's called postnasal drip. http://www.webmd.com/allergies/postnasal-drip
