Which symptom is typical of histamine poisoning?

  • A.Loss of hearing
  • B.Flushing and headache
  • C.Paralysis of the limbs
  • D.Jaundice lasting weeks

Answer: B

Correct answer: Flushing and headache

The symptoms are those of an allergic reaction because histamine is the mediator of one: flushing, headache, palpitations, sweating, an urticarial rash, sometimes a peppery taste in the mouth. Onset is within minutes to an hour and recovery is usually within a day, which distinguishes it from a bacterial infection.
