A common ingredient in many cough and cold remedies has become a popular substance to abuse by teenagers searching for a cheap, easy high.
Dextromethorphan (DXM), a cough suppressant, is found in at least 70 over-the-counter (OTC) products, including Alka-Seltzer Plus Cold & Cough Medicine, Coricidin Cough and Cold Tablets, Dimetapp DM, Robitussin cough products, Triaminic cough syrups, Tylenol Cold products, and Vicks NyQuil LiquiCaps.
Used as directed on the label, DXM products are effective at suppressing cough and are safe to use. DXM was approved by the FDA in 1958 and has no serious side effects when used in small doses — typically, 10 mg to 20 mg doses every 4 to 6 hours, or 30 mg every 6 to 8 hours.
When taken in vastly larger quantities, however, DXM produces a distorted awareness, altered time perception and hallucinations. And if taken along with other drugs — even other OTC medications like acetaminophen — the combination can cause liver damage, heart attack, stroke or death.
Cough syrup abuse has been a problem for decades, but the concern in the past had been about the alcohol and codeine in cough and cold products. Because of that, the alcohol has been removed from most OTC cough and cold remedies, and the sale of products that contain codeine are restricted by state law.
DXM seemed a good alternative to codeine and alcohol. It had few, if any side effects, when used as directed. And a larger quantity of DXM — downing several bottles of cough syrup at 1 time, for instance — would cause vomiting.
Today, teens have alternatives to drinking the syrup, however. DXM is available in powder, capsule and pill forms, particularly over the Internet. These forms can be swallowed or snorted. Some websites even tell users how to extract DXM from cough syrup and advise users how much DXM to take to get high. Illicit users may take 240 mg to 1,500 mg of DXM at a time.
It is estimated that 1 in 11 teens has abused cough medicine or other OTC products.
Slang terms for DXM include Black Beauties, Brownies, Dexies, Dextro, Drix, Gel, Groove, Mega-perls, Poor Man's Ecstasy, Red Devils, Robo, Rojo, Rome, Sky, Triple C, Tussin, and Velvet.
The effects of DXM have been compared to PCP (phencyclidine) and the anesthetic ketamine. All 3 are called dissociative substances: At high doses, they give the abuser a feeling of not being in one's own body. DXM also produces hallucinations. The effects can last up to 6 hours, but that can vary, depending on how much DXM is taken and what other drugs or chemicals are taken along with DXM.
People who regularly abuse large amounts of DXM may also be taking toxic amounts of other drugs, such as acetaminophen, found in the OTC cough and cold medications they are abusing.
Other effects of DXM include:
Nausea, vomiting and dizziness
Lack of coordination
Panic attack or seizures
Lethargy or drowsiness — or hyperactivity
High blood pressure
Rapid eye movement
Racing or pounding heartbeat
Paranoia and hallucinations
Feeling of floating
Regular abuse of DXM at high doses can lead to a chemical psychosis, a mental condition in which the person loses contact with reality. The condition may require hospitalization and treatment with medications to keep the person and others around the person safe.
As a parent, you should warn your children about the dangers of abusing OTC drugs. Some teens believe that OTC drugs are safer to abuse because they are legal.
Here are other suggestions:
Monitor the OTC drugs in your home. Keep track of how much medicine is in each bottle.
Don't buy extra OTC drugs to "stock up."
Don't allow your children to keep OTC drugs in the bedroom, backpack or school locker.
Monitor your children's Internet use, keeping an eye out for websites visited that discuss OTC or other drug abuse.
Use OTC and prescription medicines responsibly yourself.
