Confusion on Prescription Drug Label Leads to Pharmacy Mix-Ups

May 26, 2015 | Lebowitz & Mzhen

Earlier this month, the FDA issued a prescription-drug watch surrounding the anti-bacterial drug, Zerbaxa. According to a recent report by Pharmacy Practice News, the FDA’s warning was based around the fact that the dosing information on the label of Zerbaxa cartons was confusing and not uniform with other prescription drugs, leading to the possibility of a pharmacist providing a patient with an incorrect dose of the medication. The report has caused the manufacturer of the drug to alter the drug’s label to make it more accurate and more easily read.

Evidently, Zerbaxa consists of two active ingredients, both of which are listed on the front of the drug’s carton. However, on the old label, the two active ingredients were listed separately, one after another. For example, on a package that contains a total of 1.5g medicine, the label read: 1g/.5g. This could give a pharmacist the idea that the amount of medicine in the carton was 1g and that it was equal parts of each active ingredient.

In fact, according to the FDA, there have been several pharmacy errors made involving this exact situation, seven since the drug’s approval back in December 2014. In four of these cases, the patient took the extra dose and suffered an injury. Thankfully, they suffered no serious harm as a result. In the three other cases, someone caught the error before the patient actually took the medication.

Walgreen’s Pharmacy Error Nearly Resulted in Fatal Overdose

March 23, 2015 | Lebowitz & Mzhen

Earlier this month in Orlando, Florida, a woman collapsed and was admitted to the hospital after she was given a dose of medication by her pharmacist that was ten-times stronger than prescribed by her doctor. According to a recent report by one local Florida news source, the woman was filling her blood-pressure medication at a local Walgreen’s when she was provided with the wrong pills.

The woman had been taking the medication for a number of years and recalls noticing that the pills were a little larger than her normal prescription, but told reporters that she figured she had just been provided with a generic form of the drug. However, after she took just one pill she collapsed as she approached her bed; luckily it padded her fall.

Evidently, the pills that the pharmacist provided her were ten-times stronger than what her doctor had prescribed; rather than being 10mg, the pills were 100mg. The pills were the same shape, slightly larger, and had the same markings as her normal pills. When confronted about the error, the pharmacist told the woman’s husband that the 10mg pills were on the same shelf right next to the 100mg pills.

Use of “Performance Metrics” May Increase Total Number of Pharmacy Errors

March 16, 2015 | Lebowitz & Mzhen

Pharmacies are businesses. And, like all businesses, the number one goal of a pharmacy is to remain profitable. Of course, most pharmacists are good people and truly care about their patients. However, the pharmacists are rarely the ones making the staffing policies that can lead to pharmacy errors.

It has been argued by some sources that many, if not most, of the prescription errors that occur today are caused by overworked pharmacists. An understaffed pharmacy is much more likely to send out a prescription with an unprescribed medication, an incorrect dose, or a wrong number of pills.

This trade-off between the profit and safety has caused some concern over the past few years in the field. However, one new trend that is appearing in pharmacies across the country threatens to worsen the already imperfect system by applying another set of pressures on already overworked pharmacists.

Pharmacists Told To Keep Similarly Named Medications Away from Each Other

October 2, 2014 | Lebowitz & Mzhen

Pharmacists are charged with a very important duty in our society: to verify and fill prescriptions issued by physicians and to answer any patient questions that may arise. In addition, pharmacists are a second line of defense against physician error, checking prescriptions against other medications that the patient is taking.

However, with the burden on pharmacists increasing as more and more people obtain healthcare, it seems that corners are being cut, potentially increasing the risk of a pharmacy error.

In fact, one report recently released by Pharmaceutical Journal discusses a recommendation that pharmacists keep similarly named medications physically apart from one another to reduce the chance of confusion.

New Study Finds that Two-Thirds of Pharmacists Miss at Least 20% of Dispensing Errors

September 15, 2014 | Lebowitz & Mzhen

According to a study that was recently conducted in the United Kingdom, pharmacists miss errors in prescriptions in a frightening number of cases. According to a report by the Pharmaceutical Journal, the study results were unveiled at the Royal Pharmaceutical Society Annual Conference earlier this month.

The study took 103 local pharmacists and had them fill 50 prescriptions in 25 minutes, which is generally considered a normal, if slightly heavy, workload for that amount of time. Five of the 50 prescriptions intentionally contained errors. There were also a few distractions that were thrown at the pharmacists while they were filling the test prescriptions, but nothing out of the ordinary for the profession.

The idea of the study was to see how many of the pharmacists would catch all five of the errors. The results were frightening. Below is a summary of the results:

Confusing Drug Names May Lead to More Prescription Drug Errors

August 20, 2014 | Lebowitz & Mzhen

Prescription drug injuries are becoming more and more common as pharmacies try to meet the increasing demands of their customers without hiring additional staff members. While there are several potential causes for a pharmacy misfill, one recent article points out that the similarity of different drug names may play a role in the confusion, increasing the chances of an error.

Confusion Can Lead to Serious Injury or Even Death

Although some medication errors can cause little or no harm to the patient taking the drug, others can cause permanent or serious injury or even death. Suppose that the prescription is for a life-threatening condition that, if the patient does not get his or her medication, he or she could die. If a pharmacist fills that patient’s prescription with the wrong drug—even if the improperly prescribed drug was harmless—the patient may suffer serious injury or death.

Dosage confusion is also an area that can result in serious injury. If a doctor improperly prescribes a larger-than-needed dose, and the patient takes the prescribed dose, he or she may be at risk of an overdose. The same is true for an under-dose.

Study of “Collaborative Pharmaceutical Care” Finds 3/4 Reduction in Hospital Medication Errors

March 19, 2014 | Lebowitz & Mzhen

A new study, conducted in Irish hospitals and published in a British journal, reviewed the effectiveness of a “collaborative” model of managing hospital patients’ medications. The model, known as the Collaborative Pharmaceutical Care in Tallaght Hospital (PACT), involves close involvement of clinical pharmacists in all stages of patient care during their stay in the hospital. The study, which was uncontrolled, found that PACT resulted in a reduction in the rate of medication errors by more than three-fourths.

The study was published in the online edition of the British Medical Journal Quality & Safety on February 6, 2014. The researchers compared the benefits of PACT to “standard ward-based clinical pharmacy,” with a focus on adult hospital patients receiving acute care, who were prescribed at least three medications in the hospital, and who left the hospital alive. The study included 112 patients receiving care based on PACT, and 121 patients receiving standard care. They measured the rates of medication errors and of potentially severe errors per patient.

According to the description provided in the study, the primary goal of PACT is to reduce the rate of medication errors that commonly occur when a patient is transferred between doctors or departments within a hospital, or transferred from one facility or organization to another, by improving the process of “medication reconciliation” (MedRec). This involves comparing a patient’s current medication orders to the medications a patient has been taking in order to prevent omission of a necessary drug, inclusion of an unnecessary or dangerous drug, or incorrect dosages.

Washington DC News Investigation Finds Multiple Medication Errors at National Pharmacy Chain

February 27, 2014 | Lebowitz & Mzhen

In a report on its investigation of the national pharmacy chain CVS/pharmacy, Washington DC’s NBC affiliate, News 4, claims to have found numerous alleged medication errors and other problems. Consumers reported receiving the wrong prescription and, in at least one case, meeting with indifference from employees. A former CVS pharmacist with more than thirty years at the company filed a whistleblower lawsuit last year, alleging in part that the company fired him in retaliation for reporting his concerns about an increasing rate of medication errors due to staff reductions. CVS has denied the allegations against it and publicly stated its commitment to protecting patients’ health and safety.

Washington’s News 4 reported a woman’s claim that CVS made a mistake when refilling her prescription for potassium citrate, which she took for her kidneys. She noticed that the pills did not look familiar, and saw that the pharmacy had given her a bottle of potassium chloride instead of citrate. The pills look similar and have similar names, but they have very different uses. Potassium chloride is used to treat hypokalemia, or low blood potassium, and can cause serious, even fatal, complications for some kidney patients. The woman claimed that when she notified the pharmacy manager of the mistake, he responded “Well, potassium is potassium.”
The report also looked at automatic refills, a service offered by CVS and other pharmacies. This allows the pharmacy to refill a prescription at regular intervals, so that the patient does not have to call and request a refill. Problems may occur, however, if the pharmacy refills prescriptions that the patient does not want or need. An elderly patient told the news team that he ended up with more Lidoderm patches, which contain an extremely strong painkiller, than he wanted, based on the auto refill system. This could lead to confusion for some patients, who might not realize that they are receiving medications they did not request.

Pharmacy Allegedly Dispenses Adult’s Prescription to Child with the Same Name, Resulting in Near-Fatal Drug Reaction

February 20, 2014 | Lebowitz & Mzhen

The family of a five-year old boy in the Chicago area is claiming that a case of mistaken identity resulted in the boy receiving the wrong medication and suffering a near-fatal reaction with possible long-term health effects. They have filed a negligence lawsuit in Cook County Circuit Court seeking $50,000 in damages. Pharmacies and the medical professionals they employ owe a duty of care to consumers to verify not only the type and dosage of medication dispensed, but also that the correct patient receives the correct medication.

The child reportedly had a routine checkup with a physician in January 2012. The doctor discussed allergy medication with the boy’s parents, but did not write a prescription at that time. A Walgreens pharmacy allegedly called the family two days later to tell them that their prescription was ready. Believing it to be the allergy medication they had discussed with the doctor, the boy’s mother picked the prescription up and began giving it to him according to the instructions on the bottle.

The lawsuit, filed in January 2014, states that the boy slept for almost two full days after taking the medication. When the child woke up, he exhibited unusual symptoms. His neck flared, leading his parents to call 9-1-1, but it soon subsided. The boy later fainted, so his parents took him to the doctor, who told them to go immediately to the hospital. The prescription that they thought was for allergies, they learned, was actually haloperidol, an antipsychotic medication intended for an adult with the same name as the child.

Similar Drug Names Can Cause Confusion, Catastrophe if Pharmacy Makes an Error

January 15, 2014 | Lebowitz & Mzhen

Confusion between two similarly-named drugs can be harmful or even fatal if the error is not detected quickly. An error could result from any number of circumstances, such as a pharmacist who misreads a doctor’s handwriting or a nurse who accidentally administers the wrong drug. The U.S. Food and Drug Administration has procedures for comparing new drug applications to existing drugs, but this does not guard against confusion regarding drugs that are already on the market. A pharmacy journal published an account last year of one such medication error at an oncology clinic, which fortunately did not result in any complications for the patient who received the wrong medication. A version of the drug she received, however, has been implicated in numerous injuries and lawsuits.

The journal Hospital Pharmacy included an account in its June 2013 issue of a fourteen year-old girl diagnosed with acute promyelotic leukemia (APL) who received the wrong medication for about four months. APL, according to the authors, can quickly turn fatal and requires immediate treatment. Her doctors prescribed an oral dose of trentinoin, a vitamin A derivative commonly prescribed in a topical form under the name Retin-A to treat and prevent acne. It is administered orally in 10-miligram capsules to treat APL. The same basic effect that treats acne can also fight cancer cells.

After completing a course of treatment, the patient returned to the hospital about a month later. Her doctors decided to do several rounds of outpatient intravenous chemotherapy and continue the oral trentinoin. A nurse in the oncology clinic, possibly unfamiliar with the drug, instead called in a prescription for isotrentinoin under the brand name Claravis. While similar to trentinoin, isotrentinoin is primarily used to treat severe acne. It was formerly marketed as Accutane, but the manufacturer discontinued the brand in 2009, allegedly in part because of lawsuits claiming harmful side effects.
