Prescription non sedating antihistamines
Antihistamines work by physically blocking the H1 receptors, stopping histamine from reaching its target.This decreases your body's reaction to allergens and therefore helps to reduce the troublesome symptoms associated with allergy.Your doctor or pharmacist will advise you on how to take your medication, including what dose and how often.Read the leaflet that comes with your particular brand for further information.
Specialised cells and chemicals, which defend your body, can now get access to the area.(Mucosae are membranes lining body cavities such as your mouth, nose and digestive tract.) If your skin is damaged or your immune system detects a foreign substance, histamine is released from mast cells.The histamine binds to special sites (receptors) on other cells, called H1 receptors.While this is a helpful response, it also causes redness, swelling and itching.Allergic reactions such as hay fever (seasonal allergic rhinitis) are caused by an oversensitivity or over-reaction of the immune system to a particular allergen.
They have a number of uses, but are most often used to treat allergies.
