From dessert to work out, a lot of something to be thankful for can make individuals wiped out. Also, when people take an excessive amount of medicines, the impact can be unsafe. That is the reason doctors are worried about the discoveries of another study.
Liquid medicines can be tricky to measure correctly. Doctors recommend measuring drugs with tools such as medicine droppers and oral syringes. They strongly prefer the use of these over such things as kitchen spoons. But recommendations are only helpful if people follow them. And many parents don’t, the new survey indicates.
Shonna Yin is a pediatrician at New York University in New York City. She was part of the team that studied how parents interpret the dosing instructions on labels for liquid medicines. Her team recruited 2,096 parents to take part. All had at least one child who was eight or younger.
The parents read the dosing label for a liquid medicine. They then selected the tool they would use to measure it. Many chose imprecise spoons from a flatware set.
The name “teaspoon” can apply to two types of spoons. A teaspoon for baking has a precise size. It always delivers the same amount of an ingredient. But the term is also given to a spoon that is part of a flatware set used for dining. These dinnerware teaspoons can vary widely in size. A parent who uses one of those spoons risks dispensing too much or too little medicine.
Yet plenty of parents are ready to do that, the new study found. The findings will appear in an upcoming issue of the journal Academic Pediatrics.
Spooning it out, by the numbers
The scientists recruited parents who had brought a child to one of three outpatient clinics. At least seven out of every 10 people visiting these clinics come from low-income households.
The parents were randomly divided into five groups. Each received dosing instructions for a liquid medicine. Two groups received labels that only had one unit on them: milliliters, abbreviated as mL. Parents in a third group were given labels that had two units. These were milliliters, abbreviated as mL, and teaspoons, abbreviated as “tsp.” Parents in a fourth group were given labels that had mL and “teaspoons.” Parents in the fifth group were given labels that only had one unit: teaspoons, spelled out.
The parents were shown a card with labeled photos of dispensing tools. These included dosing spoons, measuring spoons, dosing cups, droppers and oral syringes. Each had markings to help measure a dose accurately. Other photos showed flatware teaspoons and tablespoons — tools that cannot measure liquids accurately.
After looking at the card, the researchers asked each parent: “If you had all of these dosing tools at home, which of these would let you give your child the correct amount of medicine?”

Parents who were given labels with teaspoon units were most likely to choose a flatware spoon. This was the case even when the label also included a milliliter option. In all, more than one-quarter (27.7 percent) of parents who were given labels that contained teaspoon units chose a dinnerware spoon. In contrast, only 8.3 percent of parents in the groups given labels with just the milliliter units chose such an imprecise spoon.
Of parents given milliliter and “tsp” instructions, 22.2 percent chose a kitchen spoon. The share was even higher, 29 to 31.8 percent, among parents who had been given milliliter and “teaspoon” instructions or “teaspoon” only instructions.
How “health literate” are parents?
Parents’ health knowledge might affect their dosing choice. The researchers describe this understanding as “health literacy.” This term “has to do with how a person understands information about their health, and how they make decisions about their health using that information,” explains Yin.
More than three out of every four parents (77 percent) in the study didn’t score well on health literacy. And this group was less likely to pick an accurate measuring tool.
Doctors and other professionals can help parents understand how to measure medicines more precisely, the authors say. After all, the stakes for getting it right are high. “Kitchen spoons come in many different shapes and sizes,” notes Yin. “Reaching for the wrong size spoon could lead to someone giving more [medicine] than intended, or less.”
The new data support guidelines by the U.S. Centers for Disease Control and Prevention and the American Academy of Pediatrics. Both recommend that doctors and drug companies label dose information only in milliliter units.
The study also supports another recommendation made by the American Academy of Pediatrics, notes Ian Paul. He is a pediatrician at Penn State College of Medicine in Hershey, Pa. That group of doctors recommends “using syringes with metric units.”
What’s more, such a switch might help parents, who can become distracted when dealing with a sick child. They could misread tablespoons for teaspoons. Or they might confuse the number for this unit with the milliliter amount. Giving 2 tablespoons instead of 2 milliliters, Yin notes, would result in a child ingesting 15 times the labeled dose. A serious overdose could cause abnormal heart rhythms or even seizures, she points out.
“It’s important for kids to start learning about how to take care of their own health, even at a young age,” argues Yin. “That way, when they are on their own, away from their parents, they will know what to do to keep them healthy.”
Centers for Disease Control and Prevention, or CDC An agency of the U.S. Department of Health and Human Services, CDC is charged with protecting public health and safety by working to control and prevent disease, injury and disabilities. It does this by investigating disease outbreaks, tracking exposures by Americans to infections and toxic chemicals, and regularly surveying diet and other habits among a representative cross-section of all Americans.
Dropper (in medicine) commonly called an “eye” dropper; it is a tool for dispensing medicines that are measured by the drop.
Milliliter One-thousandth of a liter (equal to about 1/5 of a teaspoon). The abbreviation for milliliter is mL.
Pediatrician A doctor who works in the field of medicine that has to do with children and especially child health. This field of medicine is known as pediatrics.
Statistically significant in research, if a result that is obtained is statistically significant, it means there is a very high likelihood that any difference that is measured between two or more conditions was not the result of random accidents.
Survey (v.) To ask questions that gleans data on the opinions, practices (such as dining or sleeping habits), knowledge or skills of a broad range of people. Researchers select the number and types of people questioned in hopes that the answers these individuals give will be representative of others who are their age, belong to the same ethnic group or live in the same region. (n.) The list of questions that will be offered to glean those data.
Syringe A device for dispensing medicines that uses a plunger to draw in and later release a dose. It can be used for drugs, such as insulin, that are delivered through a needle tip into the muscle. Or it can hold oral medicines that will be swallowed.
