OTC decongestants that actually work, some useful info for those of us with bad sinuses.
- pseudoephedrine taken orally.
- phenylephrine, but only as nasal spray, not if you take it orally.
- Oxymetazoline (Afrin) nasal spray and others in this broad family
- propylhexedrine, sold OTC as Benzedrex as a vapor inhaler. Unfortunately people crack open the inhaler and swallow the whole thing as a drug of abuse, so often they are out of stock seemingly because of shoplifting, or not sold at all because the pharmacies don't want to deal with the hassle.
Anything that goes directly in your nose has the potential to cause rebound congestion after a couple days which can be pretty bad.
