A variety of decongestant medications are available without a prescription. Even if it is OTC, though, you may have to ask for your favorite medicine at the pharmacy counter if it contains pseudoephedrine, which can be used to make methamphetamine.
A law that took effect in 2006 requires anyone buying a medication containing pseudoephedrine to show ID when making the purchase. An ingredient called phenylephrine has replaced pseudoephedrine in many OTC medicines, but some say they don't think it works as well at clearing congestion.
Decongestant nasal sprays are another OTC option, but don't use them for longer than three days. Overuse can create a rebound effect of narrowing and constricting the blood vessels of your nose.
