Allergy Season in Southwest Florida: What You Need to Know About Diagnosis, Treatment, and the New 2026 Guidelines
By the Care Team at Advance Medical of Naples
If you live in Southwest Florida and think allergy season only happens in the spring, think again. Our subtropical climate means that allergens are present virtually every month of the year. Tree pollen peaks in late winter and early spring, grass pollen persists through summer and fall, mold thrives in our humidity, and indoor allergens like dust mites never take a break.
For the more than 50 million Americans who suffer from allergies, this is a daily reality that affects far more than just a stuffy nose. Allergies can disrupt sleep, reduce productivity at work and school, trigger or worsen asthma, lead to chronic sinus infections, and significantly diminish quality of life.
At Advance Medical of Naples, we want our patients to know that effective treatment is available, and the guidelines for managing allergies have recently been updated with important changes.
Understanding Allergies: What Is Actually Happening in Your Body
An allergy occurs when your immune system identifies a normally harmless substance (an allergen) as a threat. In response, the immune system produces antibodies called Immunoglobulin E (IgE). These antibodies trigger the release of chemicals, including histamine, that cause the symptoms we recognize as an allergic reaction: sneezing, itching, congestion, runny nose, watery eyes, and in some cases, skin rashes, hives, or more severe responses.
The most common form of allergy is allergic rhinitis (hay fever), which can be seasonal (triggered by outdoor pollen) or perennial (triggered by year-round indoor allergens like dust mites, mold, or pet dander). Many people in Southwest Florida experience both.
The 2026 ARIA-EAACI Guideline Update: What Has Changed
In April 2026, the Allergic Rhinitis and its Impact on Asthma (ARIA) initiative, together with the European Academy of Allergy and Clinical Immunology (EAACI), published the most significant update to allergy treatment guidance in over a decade. Here are the key takeaways for patients:
- Combination nasal sprays are now first-line: For patients with moderate to severe seasonal allergic rhinitis, the new guidelines recommend combination intranasal sprays (containing both an antihistamine and a corticosteroid) as the preferred first-line treatment. These combination sprays provide faster and more complete symptom relief than either ingredient alone.
- Nasal corticosteroid sprays remain highly effective: For milder symptoms, intranasal corticosteroids alone continue to be an excellent option and are considered more effective than oral antihistamines for nasal symptoms.
- Long-term nasal decongestant use is now discouraged: The updated guidelines specifically advise against prolonged use of nasal decongestant sprays (like oxymetazoline). These products can cause rebound congestion when used for more than a few days and offer no added benefit when combined with corticosteroid sprays.
- Immunotherapy remains a powerful long-term option: For patients who do not respond well to medications or who want a more lasting solution, allergen immunotherapy (allergy shots or sublingual tablets) continues to be recommended. Studies show that immunotherapy can reduce the development of asthma in allergic rhinitis patients by approximately 30 to 40%.
Allergy Triggers Specific to Southwest Florida
Our region has a unique allergen profile that differs from much of the country:
- Tree pollen (December through April): Oak is the most significant tree allergen in our area, with a particularly heavy season in February and March. Cypress, pine, and palm also contribute.
- Grass pollen (March through October): Bahia grass is the dominant grass allergen in Southwest Florida. Bermuda grass is also present.
- Mold (year-round, peaks in summer): Our humidity and rainfall create constant conditions for mold growth. Outdoor mold spores are highest after rain, and indoor mold can develop anywhere moisture accumulates.
- Dust mites (year-round): Warm, humid environments are ideal for dust mites. In Florida, dust mite levels are consistently higher than in drier climates.
- Longer and more intense pollen seasons: Climate research shows that pollen seasons across the United States have grown longer by an average of 21 days compared to 1970, and the Southeast has gained approximately 19 additional days of pollen exposure.
When Over-the-Counter Is Not Enough
Many patients begin with over-the-counter antihistamines (cetirizine, loratadine, fexofenadine) and nasal sprays, and for mild, intermittent symptoms, these can be effective. However, if your symptoms persist for weeks, interfere with sleep, reduce your productivity, or if you find yourself relying on nasal decongestants daily, it is time to see your provider.
In-House Allergy Testing and Allergen Therapy at Advance Medical of Naples
You do not need a separate referral to an allergist. At Advance Medical of Naples, we offer in-house allergy testing and allergen immunotherapy (allergy therapy) right in our office.
Allergy testing allows us to identify the specific allergens causing your symptoms, whether they are related to pollen, grass, trees, mold, dust mites, pet dander, or chemical and environmental triggers. Once we know your triggers, we can build a treatment plan tailored to you.
For patients who want a long-term solution beyond daily medication, allergen immunotherapy is a safe, clinically proven approach that gradually retrains your immune system to tolerate your triggers. Over time, this reduces the severity of your allergic reactions and can lead to lasting relief, even after treatment is completed. For patients with both allergies and asthma, immunotherapy has been shown to improve asthma control and may even help prevent the progression from allergies to asthma in children.
The Connection Between Allergies and Asthma
Allergies and asthma are closely linked. At least half of adults and up to 80% of children with asthma have allergies that trigger their symptoms. When nasal allergies are poorly controlled, asthma tends to worsen. Conversely, treating allergies effectively can improve asthma control. If you have both conditions, managing them together as part of a coordinated plan is essential.
Practical Tips for Reducing Allergen Exposure at Home
- Use allergen-proof covers on mattresses and pillows
- Wash bedding weekly in hot water (130°F or higher)
- Keep indoor humidity below 50% using a dehumidifier or air conditioning
- Use a HEPA filter in your vacuum cleaner and consider a portable HEPA air purifier for the bedroom
- Keep windows closed during high-pollen periods and after rain (when mold spore counts spike)
- Shower and change clothes after spending extended time outdoors
- Address any visible mold or water damage in your home promptly
