When you are experiencing anaphylaxis, you will be advised to lie flat, or sit with your legs outstretched if breathing is difficult. Your legs can be elevated if you feel faint. An infant should be held horizontally (across your body). Do not hold an infant upright or over your shoulder. If you are pregnant you should lie on your left side to ensure continued blood circulation to your baby.
If you stand up too quickly after anaphylaxis, your blood pressure may drop dangerously. You should not stand up after having adrenaline - wait until a clinician assesses it is safe for you to get up. Do not stand or walk anywhere, even to the bathroom, ambulance or into the emergency department. This is usually a minimum of one hour after one dose of adrenaline, or four hours if more than one dose is given.
