It's unfortunate that anything a person has a bad reaction to is often placed in the Allergies section of their medical records without qualifiers.

True allergies cause a histamine reaction for which antihistamines can be used. Other reactions, that don't cause histamine release, include idiosyncratic (from drugs) / idiopathic (various conditions), and psychosomatic (indirect relationship). It's important for a person having reactions of more than one type to distinguish between them.

If this was a true allergy with potentially lethal consequences, you would probably have been prescribed an anaphylaxis kit and taught how to use it.

If it's not a true allergy, the antihistamine Benadryl will likely only work as a placebo for the other aforementioned types of reactions. UT suggests you should be on something stronger; however, that's not for an antihistamine effect ... that's for antidepressant and antianxiety effects. A property of antihistamines led to the development of SSRIs. Depression and anxiety have been associated with Multiple Chemical Sensitivity like you experience.
