What are antihistamine injections?
Antihistamine injections are medications that are used for the rapid treatment of:
- allergic reactions,
- motion sickness, and
- to induce sedation when injected into a patient.
Antihistamine injections are also used to alleviate extra pyramidal symptoms of antipsychotic medications.
Histamine is a chemical that causes many signs and symptoms of allergy. Histamine is released from histamine-storing cells (mast cells) and attaches to other cells that have receptors for histamine on their surfaces. Histamine stimulates the cells to release chemicals that produce effects that we associate with allergy. Antihistamines blocks histamine receptors and thus prevent activation of cells with histamine receptors by histamine.
