Acetaminophen / hydrocodone
"There is some filler in this medication that I am allergic to. The medication itself is not that effective. This company and North Star Pharma use the same filler that I am allergic to. My face, tongue, eyes, throat, ear drums, hands and feet swell so badly it renders the drug useless. I am taking the findings to an allergist and from hence forth will have to screen every drug I take. 
Thanks for that,
Sincerely,
Swollen"
