Anaphylaxis: While on holiday last year I was stung by a wasp and had a very bad reaction to it. It was so bad that I had difficulty breathing and needed emergency hospital treatment.
As I'm due to go abroad shortly I've started to worry in case it might happen again. Have you any advice on avoiding a repeat episode?
The reaction you experienced as a result of the wasp sting is known as anaphylaxis or anaphylactic shock. This is a collection of symptoms that develop when the chemical histamine is released by the body in response to exposure to an allergic substance.
In addition to swelling around the face and neck, there can be a drop in blood pressure, difficulty breathing, an asthma-like attack and gastrointestinal upset. In severe cases, it can result in death. These are all very serious symptoms and must always be treated with haste.
The first line of defence is to take precautions to avoid wasps. Never disturb a wasps' nest and stay away from areas that attract insects, such as litter bins. Don't walk barefoot out of doors and avoid wearing bright colours such as yellow or orange which seem to attract wasps. Use an insect repellent for added protection and avoid eating ice-cream and other sweet treats out of doors.
I have been given an EpiPen by my doctor in case I get a reaction again. What happens if I use it when I am not going into shock? Will the injection do me any harm?
EpiPen is a device which is designed to allow you administer a correct dose of adrenaline to counteract the symptoms of anaphylaxis. It is relatively safe to use but must be used with caution in the elderly or in those with cardiac problems. If you give yourself a dose of adrenaline that is not strictly necessary, you may feel a little unwell for a few minutes but this will pass and is preferable to waiting until symptoms become so severe that it's too late. Before going on holidays check the expiry date on your EpiPen to ensure you have adequate protection in the event that you need to use it.
With tighter security and a ban on bringing sharp objects on board a plane, will I be allowed carry the EpiPen?
Before travelling you should ask your doctor for a letter stating that you suffer from a life-threatening allergic condition which requires you to carry adrenaline with you at all times. When going through the security section inform the security staff that you are carrying the emergency treatment and show them your doctor's letter. When you return from holiday you may wish to speak to your doctor about a referral to an expert in the area of allergies.
