Hydrocodone or dihydrocodeinone (marketed as Vicodin, Anexsia, Dicodid, Hycodan, Hycomine, Lorcet, Lortab, Norco, Hydroco, Tussionex, Vicoprofen) is an opioid derived from either of the naturally occurring opiates codeine or thebaine. Hydrocodone is an orally active narcotic analgesic and antitussive. Sales and production of this drug have increased significantly in recent years, as have diversion and illicit use. Hydrocodone is commonly available in tablet, capsule and syrup form.
As a narcotic, hydrocodone relieves pain by binding to opioid receptors in the brain and spinal cord. It may be taken with or without food. When taken with alcohol, it can intensify drowsiness. It may interact with monoamine oxidase inhibitors, as well as other drugs that cause drowsiness. It is in FDA pregnancy category C: its effect on an embryo or fetus is not clearly known and pregnant women should consult their physicians before taking it. Common side effects include dizziness, lightheadedness, nausea, drowsiness, euphoria, vomiting, and constipation. Some less common side effects are allergic reaction, blood disorders, changes in mood, mental fogginess, anxiety, lethargy, difficulty urinating, spasm of the ureter, irregular or depressed respiration and rash.
Hydrocodone can be habit-forming , and can lead to physical and psychological addiction. In the U.S., pure hydrocodone and forms containing more than 15 mg per dosage unit are considered Schedule II drugs. Those containing less than or equal to 15 mg per dosage unit in combination with acetaminophen or another non-controlled drug are called Hydrocodone Compounds and are considered Schedule III drugs. Hydrocodone is typically found in combination with other drugs such as paracetamol (acetaminophen), aspirin, ibuprofen and homatropine methylbromide. The purpose of the non-controlled drugs in combination is often twofold. 1) To provide increased analgesia via drug synergy. 2) To limit the intake of hydrocodone by causing unpleasant and often unsafe side effects at higher than prescribed doses (See Below). In the UK it is listed as a Class A drug under the Misuse of Drugs Act 1971.
Daily consumption of hydrocodone should not exceed 40 milligrams in patients not tolerant to opiates. However, it clearly states in the 2006 PDR (Physicians Desk Reference) that Norco 10, containing 10 miligrams of hydrocodone and 325 miligrams of APAP (viz., acetaminophen or paracetamol), can be taken at a dosage of up to twelve tablets per day (120 miligrams of hydrocodone). Such high amounts of hydrocodone are only intended for opiate tolerant patients, and titration to such levels must be monitored very carefully. This restriction is only limited by the fact that twelve tablets, each containing 325 miligrams of APAP, puts the patient right below the 24 hour FDA maximum of 4,000 mg of APAP. Some specially compounded products are routinely given to chronic pain patients in doses of up to 180 mg of hydrocodone per day. Tolerance to this drug can increase very rapidly if abused. Because of this, addicts often overdose from taking handfulls of pills, in pursuit of the high they experienced very early on in their hydrocodone use. Symptoms of hydrocodone overdosage include respiratory depression, extreme somnolence, coma, stupor, cold and/or clammy skin, sometimes bradycardia, and hypotension. A severe overdose may involve circulatory collapse, cardiac arrest and/or death.

Hydrocodone is possibly known best by the trademark name Vicodin™ (pronounced 'VIKE-o-din'). Like Quaalude and Valium in the 1970s, Vicodin has become not just a drug but a symbol, and its presence in a lyric or a screenplay can be seen as a comment on the obsessions of the early twenty-first century. Some of the places where the brand name has appeared in popular culture include:
Analgesics | Opioids | Drugs | Schedule II controlled substances
