Some liquid medicines come with a dosing device such as an oral syringe, dosing cup, or measuring spoon.
If the label says to use the measuring device provided, it means you should measure each dose with that device rather than with a regular household spoon.
Why Does the Measuring Device Matter?
Liquid medicines need to be measured accurately.
Household teaspoons and tablespoons are not standardized and can hold different amounts. Using the wrong spoon can lead to too much or too little medicine being taken.
What Types of Measuring Devices Are Used?
Depending on the medicine, you may receive:
- An oral syringe
- A dosing cup
- A calibrated measuring spoon
- A dropper designed for that product
The correct device depends on the medicine and the dose being measured.
Are Oral Syringes More Accurate?
Oral syringes can be especially useful for measuring smaller liquid doses because the markings make it easier to measure a specific amount.
Some prescription medicines specifically instruct patients to use the oral dosing syringe supplied with the product.
Can You Use a Kitchen Teaspoon?
A regular household teaspoon should not be used to measure liquid medicine.
Household spoons vary in size, so they may not deliver the intended dose. MedlinePlus specifically advises using a medication-measuring device instead.
What If You Lose the Measuring Device?
Do not guess the dose with a household spoon.
Ask the pharmacist for a replacement device that is appropriate for the medicine and can measure the prescribed amount accurately.
Should You Measure in mL or Teaspoons?
Follow the units written on the prescription label or product instructions.
Many liquid medicines are measured in milliliters (mL). Make sure the markings on the measuring device match the units on the label.
If the instructions or markings are confusing, ask a pharmacist before giving the dose.
What About Children’s Liquid Medicine?
Accurate measurement is especially important when giving liquid medicine to children.
Use the dosing device that comes with the product or another appropriate medication-measuring device, and follow the dose instructions carefully.
When to Ask a Pharmacist
Ask a pharmacist if:
- You do not have the original measuring device
- The markings are difficult to read
- You are unsure how much liquid to measure
- The prescription label and device use different units
- You are giving the medicine to a child
- You are unsure which device is appropriate
Bottom Line
“Use the measuring device provided” means the liquid medicine should be measured with the dosing device intended for that product or dose.
Avoid using ordinary household spoons, because they may not measure the medicine accurately.
