According to the Vicodin website, Vicodin is available in 5 milligrams, 7.5 milligrams and 10 milligrams of hydrocodone. All Vicodin tablets contain 300 milligrams of acetaminophen regardless of hydrocodone content.
According to Drugs.com, Vicodin is an opioid pain medication. Acetaminophen is put in Vicodin because it increases the effectiveness of hydrocodone. Vicodin should not be used by someone who recently consumed alcohol, a tranquilizer or any kind of sedative. Users of Vicodin are cautioned that this drug can be addictive even when used responsibly and as directed. Overdose of Vicodin or any narcotic can be fatal. Drugs.com advises pregnant women to refrain from using Vicodin until use is discussed with a doctor as the likelihood of harm done to an unborn baby from usage is uncertain.
