Vicdol is a prescription medication that combines two active ingredients: hydrocodone and acetaminophen. Hydrocodone is an opioid pain reliever, while acetaminophen is a non-opioid analgesic that helps reduce fever and alleviate pain. This combination makes Vicdol effective for managing moderate to severe pain. However, due to the presence of hydrocodone, it carries a risk of dependence and should be used under strict medical supervision.
