How to Fill a Syringe Properly?
Filling a syringe accurately is crucial for administering the correct medication dosage. The process varies slightly depending on the type of medication container (vial or pre-filled syringe), but the core principles remain the same.
-
Gather Supplies: Ensure you have the correct medication, a clean syringe, and an alcohol swab if necessary.
-
Prepare the Vial: Clean the top of the vial with an alcohol swab and let it dry completely. This helps prevent contamination.
-
Draw Air into the Syringe: With the needle cap still on, pull back the plunger to draw an amount of air equal to the desired medication dose. This is important for creating pressure to easily draw the liquid out. This step is detailed in the MedlinePlus Medical Encyclopedia.
-
Insert the Needle: Carefully insert the needle through the rubber stopper of the vial.
-
Invert the Vial: Hold the vial upside down with the needle still inside.
-
Inject the Air: Push the plunger to inject the air into the vial.
-
Withdraw Medication: Gently pull back the plunger to withdraw the desired amount of medication. Avoid drawing in extra air bubbles. The MedlinePlus Medical Encyclopedia and wikiHow both explain this process.
-
Remove the Needle: Carefully remove the needle from the vial.
-
Check for Air Bubbles: Tap the syringe gently to bring any air bubbles to the top. Then, carefully push the plunger to expel the air bubbles.
-
Verify Dosage: Double-check that the syringe contains the correct amount of medication. Confirming the dosage is crucial and is implied by several of the linked articles.
Filling a Syringe from a Pre-filled Syringe (Cartridge)
Some medications come in pre-filled syringes. In this case, you would simply follow the manufacturer's instructions. The DUPIXENT® instructions stress the importance of proper training for this process.
Filling an Oral Syringe
For oral liquid medications:
-
Use the Correct Tool: Always use the measuring device, usually an oral syringe, that comes with the medication or is recommended by your doctor or pharmacist. The HealthyChildren.org article highlights the importance of using the appropriate measuring tool.
-
Proper Technique: Slowly insert the tip of the syringe into the liquid medication, ensuring it doesn't spill, and pull back the plunger to fill the syringe slightly more than the required dose. This technique is described in the video excerpt.
Important Considerations:
- Sterility: Maintain a sterile environment throughout the process to prevent contamination.
- Dosage: Always double-check the medication dosage before administering.
- Disposal: Dispose of used needles and syringes properly in a sharps container. Mass.gov's document provides guidance on safe needle disposal.
