Adrenaline is the first line of treatment for serious allergic reactions (anaphylaxis). It is available on prescription in a pre-loaded injection device known as an adrenaline auto-injector or AAI.
But the adrenaline used in these devices degrades over time and may become less effective after the expiry date. With that in mind, it is vitally important that you check the expiry date of your AAIs and request replacements a month before they are due to expire.
IF your AAI has already expired, you must replace it immediately.
