PREVENTION - CONTINUED Sinus rinse or nettipot
MEDICATIONS Antihistamines � Blocks antihistamine that are released during an allergic reaction
MEDICATIONS CONTINUED Steroid nasal spray � Decreases inflammation in the nasal passage Antihistamine nasal spray � Helps with congestion in the nose

ALLERGY SHOTS Series of shots that last from 3 -5 years Patient is given increasing concentration of allergenic extract based on what they are allergic to Changes the immune system from having symptoms of allergies to having less or no symptoms 80% of people have improvement in symptoms In children see decreased progression to asthma in those that undergo allergy shots
CONCLUSION Seasonal allergies result in symptoms like itchy eyes, itchy nose, post nasal drip, asthma, and eczema. Seasonal allergies are caused by an immune reaction to pollens and molds that we inhale. Pollens and mold have defined seasons. Avoidance of allergens is the primary treatment Other ways to treat allergies are antihistamines, nasal sprays, and allergy shots
