    Some individuals who have previous episodes of anaphylaxis are prescribed an auto-injector of adrenaline.

Anaphylaxis should be considered as a medical emergency. If on hand, a shot of adrenaline must be given as soon as possible. Some individuals who have previous episodes of anaphylaxis are prescribed an auto-injector of adrenaline. This is administered into the outer thigh muscle and held in place for 5-10 seconds. For those who were prescribed an auto-injector for the first time, the doctor can provide instructions on how to administer a shot. Family members and friends must also learn how to use the device in case of emergencies.

Always call for emergency assistance whether adrenaline has been administered or not. In case after 5-10 minutes the individual still feels sick, another injection can be given at the opposite thigh.

The individual must lie flat with the legs elevated on a low table to chair. If he/she experiences difficulty breathing, he/she can sit up to make breathing easier. In case the individual loses consciousness, move him/her in the recovery position. If the heart stops or breathing ceases, CPR must be carried out.
