medical ER alert

[starion]

Dear LungLine Nurse,
Is there a particular "Medical Alert" type jewelry or service you would recommend for patients who have risk of analphylaxis or severe allergy over other jewelry or service?  From what I've seen, most companies just make the the "jewelry" with the information provided by patient engraved on it and Medic Alert has a toll-free number as well which can be called 24/7 for the patient's file.
Thanks for any further info and/or recommendations you can provide.
Aloha,
Starion

It is important to wear something such as a bracelet or necklace that alerts others of your health problem.  However we do not recommend any specific product.

P.S.  I believe I am quite sensitive to sulfites, which is the preservative in most (or all) injectable epiphedrine formulations commonly available.  Should I be tested for this to be sure exactly what I am sensitive to?
