Precarious prescriptions
Can your doctor's poor penmanship hurt you?
To Teresa Vasquez, the news story that surfaced earlier last month about errors in the dispensing of a popular new arthritis drug, Celebrex, must have seemed chillingly familiar. On its way to becoming one of the bestselling new drugs in history, Celebrex has also earned another distinction: In 56 cases reported to the FDA, pharmacists have confused prescriptions for Celebrex with two other, similarly named drugs.
So far, apparently, the Celebrex mix-ups have caused no serious injuries. But Teresa Vasquez’s husband, Ramon — a heart patient from rural west Texas — was not so lucky. In 1995, according to court documents, Vasquez saw cardiologist Ramachandra Kolluru, who wrote out a prescription for the angina drug, Isordil, to be taken four times a day in doses of 20 milligrams. But to the pharmacist on duty at Albertson’s pharmacy in Odessa, Texas, the doctor’s scrawl looked like Plendil, a blood pressure medication with a maximum daily dose of 10 milligrams a day.
The pharmacist filled the prescription with Plendil but attached directions with the dosage for Isordil. As a result, Vasquez not only got the wrong drug, but he was directed to take it at eight times the maximum daily dosage. He took it several times, each time complaining to his wife about how poor it made him feel. The day after he began taking it, Vasquez suffered a massive heart attack. He died several days later, leaving his wife and three teenage children.
Experts say such mistakes are frighteningly common, though no accurate numbers are available. An estimated 1.3 million Americans are injured each year due to medication errors, such as getting the wrong dose or the wrong drug, according to the FDA. A study published last year in the medical journal Lancet estimated that between 1983 and 1993, the number of deaths caused by drug errors jumped 250 percent to more than 7,000 a year. How many of these deaths and injuries are due to name confusion? That’s not clear — though the U.S. Pharmacopeia, an industry trade group, estimates that about one-quarter of the 1,500 errors reported to its hot line each year involve mix-ups due to drug names that look or sound alike.
Among the fatal mix-ups reported to the FDA:
- Narcan, used to reverse an overdose of narcotics, and Norcuron, a muscle relaxant used to intubate patients.
- Pitressin, a synthetic hormone sometimes used to control bleeding in the esophagus, and Pitocin, used to induce labor in pregnant women.
- Amiodarane, an anti-arrythmic, and Amrinone, used in congestive heart failure.
- Demerol and Roxanol — both are narcotic analgesics, but Roxanol is more potent than Demerol.
Richard Chacon of Albuquerque, N.M., was one of the near misses. Chacon had been taking medication for chronic heartburn for many years, but in the summer of 1996, he noticed that the Prilosec pills he usually got looked different. He shrugged it off, figuring he’d been switched to a generic. In fact, he’d been given a prescription for Prozac. Without the protection of the right medication, his heartburn symptoms came roaring back. When he woke up one night with severe chest pain, and felt lightheaded and nauseous, he was rushed to the hospital. Since Chacon had a history of heart problems, including a double bypass procedure several years earlier, doctors were concerned that he was having a new round of cardiac trouble. After several days in the hospital, doctors discovered the error and Chacon was released in good condition.
One reason for the increase in medication mix-ups is the sheer number of drugs on the market. Bruce Lambert, an assistant professor of pharmacy administration at the University of Illinois at Chicago says there are 100,000 potential pairings of drug names that could be confused. And with around 100 new drugs coming onto the market each year, the potential for mistakes keeps growing.
“It’s a significant problem and it’s vastly underreported,” says Jerry Phillips, the FDA’s associate director for medication error prevention.
Pharmaceutical companies spend a lot of money selecting and test-marketing drug names. But critics of the industry say the companies pay far less attention to making sure names won’t be confused. “When a new name is being considered, it should be tested systematically for error prevention,” says Michael Cohen, a pharmacist who directs the nonprofit Institute for Safe Medication Practices. Potential names could be screened by a panel of pharmacists, doctors and nurses. The names could be run through a computer program, such as the one developed by Lambert, to identify look-alike or sound-alike names. “Unfortunately,” Cohen says, “the vast majority of companies don’t do that. So the FDA should require it.”
Celebrex, the new arthritis drug, was originally to be called Celebra. But drug maker Searle changed the name at the urging of the FDA, to avoid confusion with the antidepressant, Celexa. In Cohen’s view, though, the new name was not much safer. In fact, he predicted exactly what happened: that Celebrex would still be confused with Celexa, and would also be mistaken with Cerebyx, an anti-seizure medication. He pushed unsuccessfully for another change. To him, the errors that have occurred were both predictable and preventable; he continues to feel the name should be changed. “I hope we don’t have to wait until someone dies,” he says.
Searle spokesman Mark Gleason says there are no current plans to change the name, though a change is “one of a whole range of potential actions being considered.” In the meantime, he said, the company has sent out a “Dear Colleague” letter to pharmacists warning them of the potential problem. Gleason defends the company’s decision to go with the name Celebrex despite the warnings of problems. “This was mutually agreed to with the FDA,” he says. “There are 15,000 prescription drugs on the market, so it’s challenging getting brand names that aren’t like other brand names. You do your best shot. But there’s a lot of potential for human error.”
This potential for error has shot up along with the workloads of both doctors and pharmacists. “Doctors are seeing more patients than ever and pharmacists are under the gun too,” says Cohen.
Jim O’Donnell, an associate professor of pharmacy at Rush Medical College in Chicago, points out that changes in the pharmacy industry — the decline of mom-and-pop drug stores, the increasing volume of prescriptions handled by pharmacy chains and the growing use of poorly trained pharmacy technicians — have also set the stage for more errors. “The policy of some chains is that you must fill a prescription within 20 minutes,” he says.
Technology may provide some solutions: Dispensing software used by pharmacies could be loaded with special alerts that flash on the screen whenever a drug with the potential to be confused is being filled. On the other end of the prescribing chain, doctors could use computers to write prescriptions; when this approach has been tried in hospitals, it’s led to substantial reductions in errors. A simpler solution would be for doctors to type or print prescriptions, and to note on prescription forms the reason for drugs being ordered. That way when a pharmacist sees a diagnosis of heartburn, he or she will know the prescription isn’t for Prozac.
In the end, it may be the threat of litigation that makes drug companies, pharmacies and doctors pay more attention to the problem. In the Vasquez case, both Albertson’s and the pharmacist have settled a lawsuit filed by Vasquez’s widow, Teresa, and her children. But a case against Dr. Kolluru — alleging that his writing of the prescription was so bad as to be negligent — is scheduled for trial in August. “I laughingly say I’m representing the only doctor who’s ever been sued for bad handwriting,” says Kolluru’s attorney, Max Wright.
Until the FDA, along with the pharmaceutical and medical industries, makes the kind of reforms that will help protect the public, patients will need to learn to pay closer attention to the use of prescription drugs. Jimmie Anderson, of Berkeley, Calif., learned that lesson the hard way.
To control his high blood pressure, Anderson has been taking Norvasc for many years. But two summers ago, when he filled his prescription, he fell victim to one of the most common and serious mix-ups: He got the anti-psychotic Navane instead of Norvasc.
For four weeks, Anderson took the wrong medication, failing to connect his deteriorating health to the pills he thought should be helping. The first thing he noticed was his fatigue, then he felt his jaw lock up. Soon he started feeling restless. “I was walking the walls, pacing around my house,” he remembers. “I couldn’t sleep at all. It got so bad I thought I was dying.”
What may have saved his life was a visit from a friend who also took Norvasc and told Anderson he had the wrong drug. The experience changed Anderson’s approach to taking medicine and dealing with pharmacists. “Now I make sure I look at all my medications,” he says. “And I read them to make sure they’re right.”

Pick of the week: An early-’60s hipster time capsule
Pick of the week: Shirley Clarke's once-banned "The Connection" is a lean, mean saga of jazz, junk and rebellion
A time capsule loaded with smack from the bohemian underbelly of JFK-era America, Shirley Clarke’s 1961 film “The Connection” is an illustration of how much things change, and how much they stay the same. I’d be stretching to call “The Connection” a great film — it’s mannered and edgy, in a way that’s partly deliberate but also distinctive to its period — but it’s an important one in cultural and historic terms, despite being largely unknown. Watching this ensemble drama about a multiracial group of New York jazz musicians and beat philosophers in a run-down apartment, waiting for their drug dealer to show up, is like traveling back 50 years in time, only to encounter the same people you might meet on the street today (at least, in certain neighborhoods of Brooklyn, San Francisco, Austin and so on). At one point, the characters even debate the illusory distinctions between “hipsters” and “squares.”

Alcoholic writers? Coke-head stockbrokers? The links between personality type and addiction are largely overblown
Ernest Hemingway (Credit: John F. Kennedy Presidential Library & Museum) Here’s Ernest Hemingway, dead drunk on a stool in Cuba with his face on his hand and his hand on an ever-present mojito. He’s the tormented writer, hard at work at the daily scrubbing of his sins. Like the Hard-Drinking Writer, we’ve come to expect certain personality types to have certain habits: The Morose Musician with Keith Richards’ appetite for heroin; the Insecure Starlet with Marilyn’s taste for pills; the Monomaniacal Money Manager with a nose for cocaine. They are generalizations that have been imprinted by generations of popular culture. But the types don’t necessarily line up.

My suburban pot secret
I thought starting my own medical marijuana operation would be easy and safe. Then the DEA crackdown started VIDEO
(Credit: Yellowj via Shutterstock) It was sometime around 2 a.m. when I heard the car doors slam. I live on a very quiet street in Fort Collins, Colo., surrounded by working families who are usually falling asleep under the blue glow of their TVs by 10 p.m., and any noise in the night usually means that something is about to happen. And on that night I was certain it was about to happen to me.
Six marijuana plants were growing in my basement and because of shortsighted planning on my part, their odor had gotten completely out of control. Having never grown pot before, I foolishly overlooked the prominent admonitions printed in every growing guide I relied upon to help me with my harvest, that odor control was of the utmost importance. But equipment designed to mask the smell (ozone generators, activated carbon filters) is expensive. How much stench could six little plants really produce? I remember thinking. Well, a lot.

America’s pill-popping capital
Welcome to Kermit, W.Va. -- ground zero of the prescription drug epidemic
(Credit: iStockphoto/Salon) KERMIT, W.Va. — It takes less than a minute to drive past Kermit, five to tour the place entirely. An old coal mining town with barely 300 residents and one blinking light between the train tracks, Kermit has no supermarket, no clothing store, no main drag. Main Street is really a side street with rows of cottages, its biggest building, the Kermit community center, empty and boarded.
Yet in this tiny town, the Kermit Sav-Rite Pharmacy used to be as busy as a New York deli. Six employees worked the counter, lines at the drive-through window snaked around the square cinder-block building, and the parking lot was full day and night.

Recovery’s new poster boy
Bill Clegg's first addiction memoir shocked readers. We talk to him about his follow-up -- and his newfound fame
Bill Clegg (Credit: Brigitte Lacombe/Little, Brown & Co.) Two years ago, Bill Clegg’s first memoir dropped like a bombshell on the New York media world. “Portrait of an Addict as a Young Man” chronicled the handsome and hugely successful book agent’s descent into a harrowing crack addiction that cost him his career, his boyfriend and his savings — and left him broke and in rehab. In one harrowing part of the book (excerpted in New York magazine) Clegg decides to blow off a first-class flight to Berlin after a week without sleep for a crack binge and sex with the cabbie driving him to his airport hotel. Staring at his pile of drugs, he wrote, “I wonder if somewhere in that pile is the crumb that will bring on a heart attack or stroke or seizure. The cardiac event that will deliver all this to an abrupt and welcome halt.”
