Since the recent spike in air pollution in BKK, I've had what seems like a classic allergic reaction:  constantly runny nose, ghastly post-nasal drip, etc.  Fortunately, no real respiratory distress...

What's locally available to deal with these symptoms that won't cause drowsiness?  In the U.S., I'd use Claritin or Zyrtec, but I don't know what's good and available in Bangkok.

Both of these are available here.

There are locally made brands of loratadine (same as claritine). Any pharmacy will have it.
