This video explains how to give an emergency injection of liquid hydrocortisone using a standard syringe. You will need a glass ampoule of liquid hydrocortisone containing a hundred milligrams of hydrocortisone sodium phosphate, some tissues, a syringe, a green blue or orange needle. Green needles are for larger people with a BMI larger than 30, blue needles are for adults and older children and orange needles are for younger children or the upper arm. Check the expiry or best before date on the bottle. If it’s expired but it’s the only medication you have use it anyway. Notice the blue dot. This is the breaking point. Tap the ampoule to remove any liquid from the top. Now, using the blue dot as a placer for your thumb, snap the ampoule away from you. There’s less risk of a breakage if you use an amp snapper as shown. Peel open the syringe and attach the needle, pushing firmly to connect. Carefully remove the shield. Hold the ampoule with your non-dominant hand and draw up all the liquid from the ampoule with your other. Hold the syringe at eye level and tap the barrel to remove any air bubbles. Expel any air by pressing the plunger until a drop of liquid forms at the top of the needle. If you have a blue or green needle, you should inject into the middle third of the outer thigh. If you have an orange needle, it’s best to inject into the upper arm muscle. Hold the syringe like a dart and insert the needle firmly into the injection site at an angle of 90 degrees. Depress the plunger steadily until it’s empty. Use a clean tissue to gently massage the injection site. Dispose of the needle safely.
