"Works okay, but for serious cough problems, get prescription-level medicine. Does help bring up phlegm. Drink lots of water, it will help bring up the mucus faster."

"Seriously the worst! Slightly numbs my tongue but not my throat. I’ve never tried a cough drop that doesn’t work. I thought because it’s a good brand they’d be great. But it’s awful. Now I’m sick, and snowed in so I can’t go to the store, and stuck with these horrible cough drops!"
