Hydrocodone is an opioid pain-relieving medication used for treating moderate to severe pain, according to MedicineNet. Doctors also prescribe hydrocodone as a cough suppressant. It works by blocking the nerve cell receptors that allow the brain to sense pain.
Drug manufacturers combine hydrocodone with acetaminophen, which is a non-narcotic pain-relieving analgesic and fever reducer, reports MedicineNet. The brand-name drugs Vicodin, Lorcet, Norco, Zolvit and Verdrocet, feature this hydrocodone and acetaminophen combination, known as hydrocodone APAP.
Common side effects of hydrocodone APAP include sedation, dizziness, vomiting, nausea and lightheadedness. Other side effects include constipation and drowsiness. The drug is potentially habit forming, causing both physical and mental dependence, states MedicineNet.
