How would I go about confirming a caffeine allergy/ intolerance? When I consume caffeine I have what seems to be an anaphylactic reaction.

Distinctly Unusual: Caffeine allergy is unusual but has been reported in the literature. After speaking to your allergist and clarifying your history, there are several options that could be explored. Skin testing could be done but there is no standardized skin test reagents for caffeine thus the results must be interpreted with care. Oral challenges could be considered but only with your physicians supervision. ...Read more

Can methylcobalamine B12 cause anaphylaxis?

Unlikely: I have never heard of methylcobalamin causing anaphylaxis and given that it is a chemical that is naturally found in every cell of your body it is probably impossible to have such a reaction. However, a supplement containing methylcobalamin may contain fillers and binders that some could be allergic to, so one could theoretically have anaphylaxis to a B12 supplement caused by the other ingredients. ...Read more

Is there a risk of anaphylaxis with apheresis?

Unlikely: "unlikely" because an aphorism in medicine is "never say never" but highly unlikely as the stuff returned to you is the stuff that was removed minus something. No foreign material is added to which your immune system could identify and react. In fact, apheresis aka plasmapheresis is sometimes used to treat serious cases of recurrent anaphylaxis where the cause is unknown or idiopathic. ...Read more

What will the emergency room do for anaphylaxis?

The place to go: If you are having an anaphylactic reaction the ER is the place to be. Typically they will monitor your vitals, and then treat. This can be various modalities, but most common would be IV antihistamine, steroid, H2 blocker and possibly epinephrine. Anaphylaxis can lead to airway obstruction, so if needed you may be intubated in severe cases. Also your blood pressure can drop. Do not mess around. ...Read more

Can you tell me how anaphylaxis cause circulatory shock?

Can you tell me how anaphylaxis cause circulatory shock?

Can nutty beers trigger anaphylaxis? Any help appreciated!

Yes: if you are allergic to the particular nuts used in the beer. Very minuscule amounts of nuts can cause severe and even fatal reactions in people who are very allergic. A patient of mine who was allergic to peanuts suffered fatal anaphylaxis after eating chili that was thickened with peanut butter. If you are that allergic, don't take any chances, and carry and dpi-pen with you. ...Read more

Can beers that have been brewed with nuts trigger anaphylaxis?

Yes but: it depends on the nut you are allergic to. I don't believe there has been a study deciphering whether the fermentation process in beer affected the allergenicity of the nuts. The best practice is avoidance until proven otherwise. A visit to an allergist will likely help you unravel the puzzle. ...Read more

If you have not seen one yet, you should consult an allergist. ...Read more

In what way would one determine anaphylaxis as a cause of death?

In what way would one determine anaphylaxis as a cause of death?

Blood tryptase: A blood test from a corpse can be tested for serum tryptase. The blood needs to be obtained a few hours after the allergic reaction and if elevated can indicate mast cell degranulation which is a sign of an allergic reaction. An autopsy that shows eosinophils in the affected tissue (larynx, lungs, etc) may also be helpful. ...Read more

Not normal: Anaphylaxis is uncommon. It is important for you to know exactly what happened so that you can inform healthcare providers who care for you in the future.
