Histamine is a natural compound involved in allergic responses, inflammation, and regulation of gastric secretion. In medicine, it is used in diagnostic tests for allergies and, in some cases, for evaluating gastric secretion.
The medication is administered subcutaneously or intradermally, as directed by a doctor. It is important to monitor the patient for adverse reactions.
Side effects may include redness, itching, pain at the injection site, or allergic reactions. In rare cases, anaphylactic reactions may occur.
Histamine is not recommended for patients with hypersensitivity to this compound or severe conditions such as uncontrolled asthma.
