Antihistamines play a significant role in alleviating symptoms caused by the release of histamine during an allergic reaction. These symptoms can include itching, rash, swelling, and respiratory issues. By blocking histamine's action in the body, antihistamines help to reduce these effects and provide relief to the patient.
