I have a blank pill found in a bottle of hydrocodone bitartrate and acetaminophen 10 mg/500 mg My uncle has deceased and after cleaning out belongings I found these. I have other family members who have a bad back and wanted to make sure these were what they described on the prescription bottle. I surely don't want to take a chance of harming someone. I have never seen a pill without any imprint. They looked like they could have gotten wet, but all 40 without any numbers or letter. They are long, white, kinda looks like a skinney loaf of bread, or the letter I filled in. I am confused, hopefully someone will take a moment to help me out. Thank you in advance :) I can take a picture if there is someone experience at idenfying pills. Thanks again
