This pill with imprint “VICODIN 5 300” is White, Elliptical / Oval and has been identified as Vicodin 300 mg / 5 mg. It is supplied by Abbott Laboratories.Vicodin and Percocet are opioid narcotic medications. Morphine also belongs to this class. The U.S. Drug Enforcement Administration classifies opioids as Schedule 2 drugs. This means they have a high risk of abuse and could lead to physical dependence or psychological dependence (addiction). Vicodin and Percocet are both prescribed to treat moderate to severe pain. For the most part, they should only be prescribed to treat acute, or short-term, pain caused by an injury or surgery. However, in some cases, these drugs may be prescribed to treat chronic, or long-term, pain due to conditions such as arthritis or cancer. They work by interfering with how pain signals are sent through your central nervous system (CNS) to your brain. This reduces the pain you feel and makes movement and everyday activities easier.
