Griffonia Simplicifolia Overview

Benzhydrocodone, Acetaminophen Overview
-
The combination of benzhydrocodone and acetaminophen is used to relieve acute pain (pain that begins suddenly, has a specific cause, and is expected to go away when the cause of the pain is healed) that cannot be relieved by other non-opioid pain medications. Benzhydrocodone is in a class of medications called opiate (narcotic) analgesics. It works by changing the way the brain and nervous system respond to pain. Acetaminophen is in a class of medications called analgesics (pain relievers) and antipyretics (fever reducers). When acetaminophen is used in combination with benzhydrocodone to treat pain, it works by changing the way the body senses pain.
