Question

How does antihistamine work on human body?

Answer 1

Antihistamines are drugs which treat allergic rhinitis and other allergies.[1] Antihistamines can give relief when a person has nasal congestion, sneezing, or hives because of pollen, dust mites, or animal allergy.[1]Typically people take antihistamines as an inexpensive, generic, over-the-counter drugwith few side effects.[1] As an alternative to taking an antihistamine, people who suffer from allergies can instead avoid the substance which irritates them.
