Chlorpheniramine / hydrocodone
"There's no generic for this medication and it is quite expensive, but definitely worth the money. My husband had a post-nasal drip cough that just wouldn't go away, and it kept both of us up at night. He took a teaspoon of this and we both slept through the night, he didn't cough once. Felt great in the morning too, no drowsiness. Great stuff."
