How to Measure Medicine in a Syringe

Measuring medicine in a syringe requires careful attention to detail to ensure accurate dosing. Always use the appropriate syringe provided with the medication or recommended by your doctor or pharmacist. Never use household spoons or other inaccurate measuring devices.

Syringes are calibrated in milliliters (mL) or cubic centimeters (cc), which are equivalent units. The markings on the syringe indicate the volume of liquid. The size and spacing of the markings vary depending on the syringe's capacity. A 1 mL syringe, for instance, has longer lines marking each 0.1 mL increment. To measure 0.24 mL, you would fill the syringe until the top of the plunger aligns with the 0.24 mL mark.

  • Example: A 1 mL syringe's longer lines represent 0.1 mL increments. Shorter lines may represent 0.01 mL or 0.02 mL, depending on the syringe.

  • Important Note: Always check the markings on your specific syringe before measuring.

Using the Syringe

  1. Select the correct syringe: Use the measuring device provided with the medication. If none is provided, obtain an appropriate oral syringe from a pharmacy.
  2. Draw up the medication: Carefully draw the liquid medicine into the syringe to the prescribed measurement line. Avoid creating air bubbles.
  3. Verify the measurement: Double-check that the plunger aligns precisely with the correct measurement line.
  4. Administer the medication: Administer the medication as directed.

Different Syringe Sizes

Oral syringes come in various sizes (e.g., 1 mL, 3 mL, 5 mL, etc.). The size you need depends on the dose of medication. Pharmacists can help you choose the right syringe for your medication.

  • Milliliters (mL) and cubic centimeters (cc) are interchangeable terms for volume measurement in syringes.

  • Do not use measuring spoons typically found in kitchens for administering medications.

Remember, accuracy is crucial when measuring medication. If you have any questions or concerns, consult a pharmacist or your doctor.
