Anti-flu & Allergies

Antiviral drugs are recommended for both treatment and prevention of flu. Antiviral drugs work best when taken within 48 hours of onset of flu symptoms, but they may still offer benefits when taken later. These medications may reduce the duration of flu by one to two days and prevent severe flu complications. Allergies occur when the body’s immune system responds to a substance it considers an “invader.” Substances that provoke the immune system into an allergic response are known as allergens. There is no such thing as a universal allergen. What might trigger a life-threatening allergic response in one person might cause absolutely no harm in another. The physiological mechanism of allergic reactions is the same, however, in everyone. Allergens enter the body — either through ingestion, inhalation or contact with the skin or mucus membranes. This causes white blood cells to release an antibody which then binds to what are known as mast cells. The mast cells rupture – and in the process, release biochemical substances including histamine. Mild allergy symptoms include itchy, watery eyes, a runny nose, scratchy throat and a rash. More severe, life-threatening allergy symptoms include swelling of the throat, wheezing and difficulty breathing.
