Hydrocodone 5-325mg refers to a prescription combination medication that contains 10 mg of hydrocodone, a powerful opioid pain reliever, and 535 mg of acetaminophen, a commonly used non-opioid analgesic and fever reducer. While 10-535 mg is not a standard formulation typically seen in the U.S. (standard combinations usually include 325 mg, 500 mg, or 650 mg of acetaminophen), this description assumes it's a custom or compounded dose available through specialized pharmacies.
