Remove the protective cap from the needle or nozzle of the syringe. Draw air into the syringe by pulling back the plunger until the desired amount of air is in the syringe. The amount of air should be equal to the amount of medication you need to withdraw. Insert the needle or nozzle into the medication container, ensuring that it is fully submerged. Push the plunger down slowly and steadily to inject the air into the container. This creates positive pressure, making it easier to withdraw the medication. Keeping the needle or nozzle submerged in the medication, slowly pull back the plunger to draw the desired amount of medication into the syringe. Make sure to withdraw slightly more than the required amount to account for any air bubbles. Remove the needle or nozzle from the medication container, keeping the syringe upright to prevent any spillage. Check the syringe for air bubbles. If there are any, gently tap the syringe to make the bubbles rise to the top. Slowly push the plunger to expel the air bubbles until only medication remains in the syringe. Administer the medication as directed by your healthcare professional. This may involve injecting the medication directly into a vein, muscle, or other specified location. 11. After use, dispose of the syringe and needle safely in a sharps container or as per your local regulations. It is important to note that the steps may vary depending on the specific medication or substance being used. Always follow the instructions provided by your healthcare professional or the medication's packaging insert.
