What type of medication cures post-nasal drip?

I have been having breathing problems for as long as I can remember. I have tried nasal sprays and they do not work. Please any advice will be much appreciated. Thank you!

Well instead of a spray maybe you should try taking a pill-based form of medicine?

I know that Sudafed works for post-nasal drip but it does not cure it. It just basically helps you deal with every-day irritants.

But before you just go out and buy a package you should ask your doctor if you should take it or not. People can have different reactions to it.
