What is the expected outcome of administering an antihistamine?

Increased allergy symptoms

Reduction in allergy symptoms

Administering an antihistamine is primarily aimed at reducing allergy symptoms. Antihistamines work by blocking the action of histamine, a substance in the body that is responsible for many of the symptoms associated with allergic reactions, such as itching, sneezing, and nasal congestion. By inhibiting histamine's effects, antihistamines help alleviate the discomfort caused by allergies.

The expected outcomes following the administration of an antihistamine include relief from symptoms such as runny nose, watery eyes, and hives, making it a crucial medication for individuals experiencing allergic reactions. This reduction in allergy symptoms is the primary therapeutic goal when using these medications.
