Antihistamines
Antihistamines are medicines used to alleviate the effects of allergic reactions by blocking the action of histamine, a molecule involved in inflammation and allergic symptoms, such as itching, redness, or skin rashes. In dermatology, they are frequently prescribed to relieve symptoms of urticaria, atopic eczema, or insect bites. Antihistamines are available in oral, topical, or injectable forms.
