Why You May Soon Need a Prescription for Sudafed

When a cold hits, New Jersey resident Ann Hilligan heads to the counter at her local pharmacy and asks for Sudafed. She's given a box after presenting a picture I.D. Her purchase is then logged.

The 37-year-old mom of two told WalletPop that she's willing to go through all that because "I like the original formula. It works better."

For consumers like Hilligan living in states like Tennessee, Missouri, Alabama, Nevada and Oklahoma, cold and allergy season may hit a little harder and take a bigger bite out their wallets this year.
