Nasal Congestion
"I have taken Sudafed (pseudoephedrine) for many years, and have found it to be the only OTC medicine that really dries up nasal congestion.  Nowadays, &quot;Sudafed,&quot; the brand name, is being sold with other ingredients, because pseudoephedrine can be used for illegal purposes in drug manufacture.  When buying it at the pharmacy counter, one must show ID, so their name can be entered on a registry; a person can&#039;t buy frequent or large quantities of the medication.

But if you get the real thing, it really works."
