Deadly Duo: Mixing Alcohol and Prescription Drugs Can Result in Addiction or Accidental Death

Alcohol and Xanax, both found in Whitney Houston's hotel room right after she died, inhibit the central nervous system and depend on the same enzyme for bodily clearance

The mystery of Whitney Houston's death will not be solved for several weeks, as the Los Angeles County Coroner's Office awaits a full toxicology report. But many experts speculate that the singer's tragic demise involved a deadly cocktail of alcohol and prescription drugs, including Xanax.

Houston wouldn't be the first star to suffer such a fate: Heath Ledger, Michael Jackson and Anna Nicole Smith are all thought to have died in part from prescription drug overdoses, which can involve painkillers, sedatives and stimulants, often in combination with alcohol. But the problem extends far beyond Hollywood. In 2007 some 27,000 Americans died from unintentional prescription drug overdoses—making prescription drugs a more common cause of accidental death in many states than car crashes are.

A slippery slope
Although sedatives are thought to have played a role in Houston’s death, most prescription drug overuse involves opioid painkillers. Approximately 3 to 5 percent of people who take pain medication eventually end up addicted, according to Nora Volkow, director of the National Institute on Drug Abuse, an arm of the U.S. National Institutes of Health. And "individuals who have a past history of a substance-use disorder—from smoking, drinking or other drugs—are at greater risk," she says. Addiction to other classes of prescription drugs such as sedatives, stimulants and sleep medications is thought to be less common—but it occurs, and even users who do not become compulsively addicted can, over time, become physically dependent and experience intense withdrawal symptoms when their prescriptions run out. They might also develop drug tolerance, the need to take higher doses over time to feel the same effects.

Other people start taking prescription drugs just to get high, perhaps in part because they have the (false) notion that prescription drugs are safer to experiment with than are illicit drugs. "They take them for recreational purposes, and then a portion of them find 'Wow, I can't stop using this,'" says Jon Morgenstern, director of addiction treatment at the Columbia University Medical Center.

It is unclear how Houston developed her substance problems, but like many other addicts, she eventually began mixing drugs along with alcohol. Many prescription drug users who are not addicted or dependent consume alcohol concurrently as well, despite medical advice against it. According to a 2008 study published by researchers at Brown University and the University of Rhode Island, 60 percent of people who regularly take prescription drugs known to interact with alcohol also drink, and 5 percent have at least three drinks in a row when they do.

Prescription drugs and alcohol can be a dangerous combination, Volkow says. Painkillers and booze are perhaps the worst to mix, because both slow breathing by different mechanisms and inhibit the coughing reflex, creating "a double-whammy effect," she says, that can stop breathing altogether. Alcohol also interacts with anti-anxiety drugs (including Xanax), antipsychotics, antidepressants, sleep medications and muscle relaxants—intensifying the drugs' sedative effects, causing drowsiness and dizziness, and making falls and accidents more likely. A 2010 study published in the Canadian Journal of Public Health reported that automobile drivers were much more likely to weave and speed if they were under the influence of drugs like Xanax in addition to alcohol than if they had consumed alcohol alone. And according to a 2011 study published in the AmericanJournal of Therapeutics, people who visited an emergency room after taking too much of the sleeping drug Ambien were more than twice as likely to end up in an intensive care unit if they had also consumed alcohol, compared with Ambien-takers who had not had anything to drink.

    Using a hot tub after taking these drugs promotes a lower blood pressure which contributes to fainting - and consequently drowning.... this is what probably happened in Housten's case.

    Yes, but nobody dare point out the facts concerning a dope addict else they get suspended from their radio show!

    A small but important clarification if I may.

    Every person reacts somewhat differently to every psychoactive drug. You cannot accurately predict how a drug like alcohol or Xanax might effect you by observing its effects on others. So, even if it is prescribed you need to check your personal reaction carefully and contact your doctor immediately if you feel that something is wrong. Also, your past experience with a drug may not be predictive of future experiences. Good trip/bad trip. You just don't know beforehand.

    If you use two psychoactive drugs together you dramatically increase the likelihood of something going very badly wrong. There are two common problems:

    A synergistic reaction. The two drugs together produce an unexpected and unpredictable effect that neither of the drugs alone would be likely to produce.

    Potentiation. The two drugs enhance each others effects in such a way that the overall effect will be much greater than if you took just one drug alone. Again this is unpredictable.

    Synergy and potentiation can occur together.

    If that doesn't scare the #%@!!?* out of you I don't know what will.

    Of course studies mean nothing to druggies, but most of the addicted people I've treated over the past 5 years got there on prescription meds, then added alcohol and other drugs, and really had no clue what was happening to them. Better information is important for all of us regardless of the %age of folks who won't pay attention. Sorry to sound so preachy, but recently I've seen so many confused (how did I get like this?) people, and its sad.

    Selling pain killers & hypnotics to adults, like how alcohol is sold, is the best way to handle the overdose & addictions problems (in conjunction with increased education about drugs in general). Having a doctor give the drugs as medicine implies that there is a health benefit to using them; that illusion fools many. I was fooled by that illusion about amphetamine, plus, I kept getting them because I was afraid of losing the prescription & thus access; because I couldn't buy them legally, I couldn't wean myself off very easily & I ended up in rehab & with lots of suffering. Education & legalisation is the best approach to drugs; alcohol use should be scrutinized to the same extent the use of other hard drugs is too.

    Studies do mean something to 'druggies': it seems that most 'druggies' who drink wine or beer each night do not even know they're using a hard drug. Education about drugs should improve & terms like 'druggies', which have an air of slander via the suggestion that the addicted people are defined only by the addiction, should be avoided.

    I disagree; education affects people. ~50% of human behavior is genetic, ~40% comes from the environment/peers & 10% of behavior comes from one's parental/guardian influence: therefore, 50% of behavior can be shaped by education. The positive affects of good education are well documented, so the slanderous & rude comment about hard-drug addicts being flippant to facts is not fair.

    Sorry Toby, I was just responding with his language. I agree that word usage matters, and that turning people into "junkies" or "stoners" is harmful. People with an addiction need assistance, not judgement

    i repeat. a silly study. doctors are going to suddenly say : Gee whiz!". Crap, they've ebeen told this 40 years ago, 20 years ago, last year.

    Doctors don't turn anyone into stoners. People are responsible and do it to themselves. Druggies are responsible for their own behavior. Alcoholics are responsible for their own behavior. The idea that peope are too ignorant to know not to take too many drugs or not to drink too much is naive. It's just enabling further bad behavior,

    This is a good article, but there is a small error. It is true that alcohol can inhibit the metabolism of some other drugs via competition for cytochrome p450 enzymes. See, for example, this article: http://pubs.niaaa.nih.gov/publications/arh23-1/40-54.pdf. However, there are many different enzymes in the p450 family. Alcohol (ethanol) is metabolized (in part) by a kind of cytochrome p450 enzyme, CYP2E1. CYP2E1 also is responsible for metabolizing Tylenol and barbiturates; these are important interactions. The point is that Xanax (alprazolam) is not metabolized by CYP2E1. Rather, it is metabolized by a different cytochrome p450 enzyme: CYP3A4. (http://www.nature.com/tpj/journal/v2/n4/abs/6500115a.html)

    Of course, alcohol and Xanax do interact, but the interaction is a pharmacodynamic one, not a pharmacokinetic one.

    thank you for the precise detail on drug clearance. I note that this makes alcohol and acetaminophen a really bad combination too; how many people have been made aware of that? Acetaminophen kills at least 100 people a year through liver failure, and hospitalizes thousands.

    Yes. Studies do mean something to "druggies," sometimes they mean a lot.

    A mechanism in this kind of deaths is suspected from a long time, and the death of Marilyn Monroe may have followed such a path. The person suffers from chronic sleep problems, and is using some kind of drug to relieve this, and also is an alcohol user. He/she goes to bed, and takes an sleeping pill, becoming drowsy, entering a reduced or dawn conscience state. As he/she's not sure of having taken the pill, he/she takes another one, the process is repeated several times, resulting in a lethal overdose, tha was easier to reach with Barbiturates, the kind of sleeping pills in Marilyn's times. A pity, let them rest in peace. Salut +

    How about the over-the-counter drugs so heavily promoted on TV?
    NyQuil is a sedative promoted as a cold remedy. My pharmacies do not stock Motrin, only their store-brand substitutes, so when an MD advises "Motrin" the only one found on my local pharmacy shelves is "Motrin Plus", which the fine print explains includes a sedative. Does every drug store customer carry a magnifier to read the fine-print ingredients? "Plus" implies it's better than the non-plus variety, w/o warning that it is even more dangerous.

    Too many people still regard addiction as a character defect rather than a legitimate brain disease. Education about the science of addiction can help combat the stigma and encourage people to get treatment. For a website that discusses addiction science in accessible English, from the viewpoint of a long-term sober alcoholic, please check out www.AddictScience.com.

    I took my time and read all the statements here, I will not use a PHD that I do not have but I will share a truth, most alcohol drinks have Opoits, known as Opoid. Heroin to be more to the point.
    It should also be noted that in fact 27,000 Americans did die from This Health Care Concept for Pain. But in a study 1.3 Million people between Canada and the USA are also dead, in the last 10 years.
    This study also placed a fact that not one Government Official or any one within their family died from Oxy Heroin.
    Within the Cartel Family it is forbidden to give family members Narcotics, but some Drug Lords do indulged.
    The thing you over look is that if this Oxy Heroin was so good for our Economy, Where Is The Money ? Seeing how Government Officials state our children are around $30,000 dollars in debt to cove our Economy fall out. I wonder how Mom can share with a 4 year child that they are in debt. I shared this here like this in order to show you that in all things is a truth, and some how in my life I have become the Founder and Director of the International Boycott Of The Arabic Drug Empire.
    Sometimes I do not think people hear the tear of the ones who died. The reality of this are the on going deaths clime, according to your Laws, was it to be noted something is terribly wrong after 5000 deaths, or 10,000 or how many people have to die from a Health Care Concept that has failed and is in conflict of your Constitutional Laws in and for The Safe Keep Of The people.

    Good point. Also factored into the equation is the amnesia-related side effects of most benzodiazepines. (Not sure about the selective GABA inhibitors such as zolpidem)
    Benzo's cause retrograde and anterograde amnesia in varying degrees depending on the particular drug in question.
    Flunitrazepam (Rohypnol) was a classic drug re: this side-effect, thus it was first choice as a date-rape drug.
    It is now classed as an S8 drug in Australia, same as Scedule II narcotics in the U.S....much harder to obtain.
    Not sure if this was a genuine side effect of the Barbiturates though the associated confusion after swallowing a couple of Seconal's would be on a par with the retrograde amnesia.
