Allergies affect millions of people year-round, triggered by pollen, dust mites, pet dander, mould, and certain foods. This section provides neutral, factual information about the prescription and over-the-counter antihistamine and allergy-relief medications most commonly discussed with healthcare professionals.
About Allergy Medications
Allergy medications fall into several categories. Antihistamines are the most widely used — they block histamine receptors, reducing sneezing, itching, and runny nose. Second-generation antihistamines such as fexofenadine, loratadine, and cetirizine are generally preferred because they cause less sedation than first-generation options like diphenhydramine. Hydroxyzine is sometimes used when a stronger sedating antihistamine is appropriate under medical supervision.
