Do antihistamines cause the symptoms of allergic reaction?

No, antihistamines do not cause the symptoms of an allergic reaction; rather, they are designed to alleviate those symptoms. Allergic reactions occur when the immune system overreacts to allergens, releasing histamines that lead to symptoms like itching, swelling, and hives. Antihistamines work by blocking the action of histamines, thereby reducing these symptoms. However, some individuals may experience side effects from antihistamines, such as drowsiness or dry mouth, but these are not related to allergic reactions.
