Abstract
This case is, in many respects, typical of the multiple sensitivities of polysymptomatic patients who react to aeroallergens, foods and chemicals. However, the case has a number of unusual aspects: migraine provoked by pollen, irritable bowel symptoms caused by reactions to a water-soluble metabolite of tetracycline in animal products, and bladder symptoms apparently owing to the excretion of amitriptyline metabolites and of sulphites in molybdenum deficiency. Sensitivity to drug metabolites was probably acquired by the vaginal route.
