Anti Allergies
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.
Product Description
The physiological mechanism of allergic reactions is the same for everyone. Allergens enter the body — through ingestion, inhalation, or contact with the skin or mucous membranes. This triggers white blood cells to release an antibody, which binds to mast cells. These cells rupture and release substances like histamine, causing allergy symptoms.
Mild symptoms: Itchy, watery eyes, runny nose, scratchy throat, rash.
Severe symptoms: Swelling of the throat, wheezing, and difficulty breathing.
Guidelines
Allergy medications are available as pills, liquids, inhalers, nasal sprays, eye drops, skin creams, and injections. Some are over-the-counter; others require a prescription.
Clinical Research
Pills and liquids: Oral antihistamines—available OTC and by prescription—relieve runny nose, itchy/watery eyes, hives, swelling, and other allergy symptoms. Be cautious: some antihistamines cause drowsiness and fatigue, which can affect activities like driving.
Common drowsiness-inducing antihistamines:
- Diphenhydramine
- Chlorpheniramine
