Allergies occur when the body reacts negatively to foreign substances such as environmental factors, foods, or medications. While symptoms can be minor, in severe cases they can become life-threatening. As of 2018, more than 50 million Americans suffer from some form of allergy, and although there is no cure, many allergies can be managed with over-the-counter (OTC) or prescription medications.

What Are Seasonal Allergies?

The most common seasonal allergy is seasonal allergic rhinitis—an allergic reaction to pollen from trees, grasses, and weeds. Rhinitis causes inflammation in the nose, leading to symptoms such as mucus buildup and post-nasal drip. Seasonal allergies can also trigger eye irritation and are often confused with the common cold. However, allergies typically involve more itching and last 2–3 weeks per allergen, while colds usually resolve within a week.

Common Symptoms of Seasonal Allergies

• Itchy nose and eyes
• Runny nose
• Sneezing
• Excess mucus production
• Post-nasal drip

Seasonal allergies affect more than 24 million people in the U.S., with symptoms most prevalent during high pollen seasons.

Prevention Tips for Seasonal Allergies

• Avoid touching your eyes and nose.
• Wash hands frequently with soap and water.
• Use allergy-friendly filters in your vacuum, home, and car.
• Wear hats, sunglasses, and long sleeves when outdoors.
• Keep windows closed to prevent allergens from entering the home.

Treatment Options for Allergy Relief

• Medications such as antihistamines, decongestants, and nasal corticosteroids.
• Avoiding triggers, especially during peak pollen seasons.
• Immunotherapy, including allergy shots or sublingual immunotherapy (SLIT) tablets for dust mites, grass, and ragweed.

If your symptoms persist despite treatment, seeing an allergist can help identify your specific triggers and create a personalized treatment plan for long-term relief.
