Vicodin is a combination medicine used for moderate to severe pain. It contains a narcotic, hydrocodone, and acetaminophen. Hydrocodone works in the brain to change how your body feels and responds to pain, while Acetaminophen is a less potent pain reliever that increases the effects of hydrocodone.
Dosage should be adjusted according to the severity of the pain and the response of the patient. However, it should be kept in mind that tolerance to hydrocodone can develop with continued use and that the incidence of untoward effects is dose related.
The usual adult dosage for Vicodin 5 mg/300 mg is 1 or 2 tablets. This is taken every 4-6 hours as needed for pain. Also, the total daily dosage should not exceed 8 tablets.
Also the usual adult dosage for Vicodine 7.5 mg/300 mg is 1 tablet. This is also taken every 4 -6 hours as needed for pain. The total daily dosage should not exceed 6 tablets.
People who take Vicodin in high doses risk liver damage which can be fatal. Thus too much acetaminophen intake causes problems. For those without existing liver problems, the adult daily dose should not exceed 4 grams. In addition, patients should read labels carefully. This is to therefore sure, there is no acetaminophen in any other medication they are taking.
Seek medical help if any of these symptoms develop: severe nausea, dark urine and stomach pain. Also yellowing of the skin or eyes. In addition, because of the acetaminophen, you may not be able to take this drug if you consume more than 3 alcoholic drinks per day or if you have cirrhosis of the liver.
