What are the signs of a caffine allergic reaction?!

An allergic reaction to caffeine would pretty much be like a reaction to any other allergen. You could experience nausea or vomiting, rashes, itching, headaches, throat irritation and trouble breathing if your reaction becomes severe enough (anaphylaxis) and that would require emergency treatment with an epi-pen. Please note that these reactions vary from person to person. Here are two websites that explains food allergies: http://www.foodallergyinitiative.com http://www.foodallergy.org.
Please consult your doctor if you find that you are experiencing severe reactions to caffeine or any other allergen. Hope this helps...Good luck!Health Question & Answer
