On this page, you can find the following information:

Tips for measuring liquid medicines

  • Ask your pharmacist to show you how to measure the right amount of each medicine in the right syringe.
  • Check with your pharmacist each time you get medicine because the strength or dose may have changed.

What is a medicine syringe?

A medicine syringe is used to give liquid medicines by mouth to babies and children, and to adults who have problems swallowing tablets or capsules. It helps you measure the exact dose. Medicine syringes usually have markings on them so that doses are measured in milliliters (mL).  

Why should I use a medicine syringe?

When measuring liquid medicines, always use a proper medicine cup, spoon or syringe to give the correct dose. Don't use a kitchen teaspoon or a measuring spoon designed for cooking. They are not accurate enough to measure medicine.

Kitchen spoons come in different shapes and sizes, which give different measurements. Using them could cause you to take (or give) a dose that is too high or too low. Instead always use the measuring device provided with your medicine.

If a measuring device is not provided with your medicine, ask your pharmacist for help in choosing one. You can also ask your pharmacist to show you how to use it.

Where can I get a medicine syringe?

Some liquid medicines come with their own measuring syringe or you can buy one from your pharmacy.

Examples of medicine syringes

Not all medicine syringes are the same. Each has different markings. It is important to understand the markings clearly for each medicine to measure the correct dose. 

Ask your pharmacist to show you how to measure the right amount of each medicine in the right syringe. Check with your pharmacist each time you get medicine because the strength or dose may have changed.

What is a syringe adaptor?

Some medicine syringes come with an adaptor or a bung– a plastic or rubber fitting that fits into the medicine bottle. These help to fill the syringe with medicine. To measure the liquid using an adaptor, you put the adaptor into the top of the medicine bottle, then insert the syringe into the adaptor and draw the required amount. It makes measuring the medicine much easier without spilling.

How do I use a medicine syringe safely?

Measuring the dose accurately

Read the directions carefully to see how much to take or give your child. Don't just fill the syringe to the top. Look at the numbers on the side of the syringe and use the numbers to fill it to the right line for the dose that you need.

If a measuring device is provided with the medicine, take the time to check it with the your pharmacist before you leave the pharmacy. Show the pharmacist how you would measure the medicine and repeat back any special instructions. This helps the pharmacist know if they have explained what to do clearly, so you can give the medicine safely.

Giving the medicine

To prevent choking you need to use the correct technique when giving medicine to someone using a syringe.

Do's Don'ts
✔ If giving the medicine to a child, put the tip of the oral syringe inside your child’s mouth between the gums and inside of their cheek. Gently push the plunger to push small amounts of medicine into their mouth at a time. Let your child to swallow before you push the plunger again.

✔ Give your child a drink to wash down the medicine. This makes it easier to swallow
✘ Don't put the medicine in the back of their throat or squirt all the medicine into their mouth in one go, as this could cause choking.

How do I clean a medicine syringe?

When you have given the whole dose of liquid medicine, wash the syringe in warm soapy water. Draw the plunger in and out in the soapy water several times. Rinse with clean running water.  The syringe is now ready for use for the next dose. Do not place the syringe in boiling water, a microwave or oven.
