Lortab is a form of Hydrocodone, brand name Vicodin. 5 mgs. of Hydrocodone, and 325 mgs of APAP, or brand name Tylenol. Just read the TOP number for your pain medicine dosage, and BOTTOM number for whatever has been added as an adjunct medication such as Tylenol, Ibuprophen, mainly those two are used. Many quote their pain meds as "I take 500 mgs. of Vicodin." That dose wouldn't go over to well!!!
