Florida hurricane season officially runs from June 1 through November 30. Most people prepare for storms by stocking supplies and securing their homes. What fewer people think about is what happens to their allergies and asthma in the weeks and months after a storm passes.

Mold is one of the most potent and most overlooked allergy triggers in South Florida, and hurricane season is when it becomes a serious problem for a large portion of the population.

Why Mold and South Florida Are a Difficult Combination

Mold is a type of fungus that grows wherever there is moisture, warmth, and an organic surface to feed on. South Florida checks every one of those boxes year-round. High humidity, warm temperatures, and frequent rain mean that outdoor mold levels in Palm Beach County are elevated for most of the year, even without a hurricane.

During and after a storm, those conditions intensify significantly. Heavy rainfall saturates the ground, floods low-lying areas, and drives water into homes and buildings through roofs, windows, and doors. Once moisture gets inside, mold can begin growing within 24 to 48 hours on drywall, wood, carpet, insulation, and furniture.

The problem is compounding. Outdoor mold spore counts spike during and immediately after storms. At the same time, indoor mold starts growing from water intrusion. People who spend more time indoors during storm recovery may actually be more exposed to mold, not less.

What Mold Allergies Feel Like

Mold releases tiny reproductive particles called spores into the air. These spores are small enough to be inhaled deep into the respiratory tract. For people who are allergic to mold, the immune system treats these spores as a threat and launches an inflammatory response.

Symptoms of mold allergy typically include nasal congestion and a runny nose, sneezing, itchy or watery eyes, postnasal drip (mucus dripping down the back of the throat), coughing, and skin irritation. For patients who also have asthma, mold exposure can trigger significant flares, including wheezing, chest tightness, and shortness of breath.

One of the reasons mold allergy is frequently underdiagnosed is that its symptoms look nearly identical to other common allergies and to upper respiratory infections. Many patients assume they caught a cold after a storm when they are actually reacting to mold spores. The key difference is duration. A cold resolves within 7 to 10 days. Mold allergy symptoms persist as long as the exposure continues.

Where Mold Hides After a Storm

After a hurricane or heavy flooding event, mold does not always grow in obvious places. Visible black or green mold on walls is easy to spot. The mold that causes the most persistent health problems is often hidden.

Common places mold grows after water intrusion include inside wall cavities behind drywall, under flooring and subflooring, in attic insulation that absorbed roof leaks, inside HVAC ducts and air handling units, behind kitchen and bathroom cabinets, and in crawl spaces and garages.

HVAC systems are a particular concern in South Florida. When an air conditioning unit or ductwork becomes contaminated with mold, it distributes spores throughout the entire living space every time the system runs. Patients who develop persistent respiratory symptoms after a storm and cannot identify a visible source of mold in their home should consider having their HVAC system professionally inspected.

How to Reduce Your Mold Exposure After a Storm

The most effective way to manage mold allergy during and after hurricane season is to reduce exposure. Treatment helps, but removing or limiting the source is always the priority.

After any water intrusion event, act quickly. Remove standing water and wet materials within 24 to 48 hours if at all possible. Wet drywall, carpet, and insulation that cannot be thoroughly dried should be removed and replaced rather than dried in place. Run dehumidifiers continuously in affected areas and aim to keep indoor humidity below 50 percent. Hard surfaces that got wet can be cleaned with appropriate antifungal solutions, but porous materials like drywall and carpet generally cannot be fully remediated once mold takes hold.

When outdoor mold counts are high, which is particularly common in the days immediately following a major storm, keeping windows closed and running air conditioning with a clean, high-quality filter can help reduce the amount of outdoor spores entering your home.

If you have a known mold allergy, wearing an N95 mask during outdoor cleanup work after a storm is a practical protective measure.

When to See an Allergist About Mold

Many people in Palm Beach County have a mold sensitivity and do not know it. If your allergy or asthma symptoms reliably worsen during the summer and fall months, if they spike after heavy rain events, or if they got significantly worse after moving into a particular home or after a flooding event, mold is a strong suspect.

A board-certified allergist can perform food and environmental allergy skin testing or specific blood testing to confirm whether you have a mold allergy and identify which mold species you are reacting to. This matters because there are many species of mold and not everyone is sensitive to the same ones.

For patients with confirmed mold allergy, allergen immunotherapy (allergy shots) can be an effective long-term treatment. Immunotherapy for mold works the same way it does for pollen or dust mites: by gradually desensitizing the immune system to the specific allergen so that future exposures trigger a smaller response.

For patients whose mold allergy is driving asthma symptoms, a full asthma evaluation including FeNO testing and pulmonary function testing may also be recommended to understand the degree of airway inflammation and optimize the treatment plan. How do I know if I have a mold allergy or just a cold after a storm? The biggest difference is duration and pattern. Cold symptoms typically resolve within 7 to 10 days. Mold allergy symptoms persist as long as mold exposure continues, and they tend to worsen in humid conditions or after rain. If your symptoms keep coming back every storm season or linger for weeks after a flooding event, allergy testing is worth pursuing.

Is outdoor mold or indoor mold more likely to trigger my symptoms? Both can cause significant symptoms, but indoor mold is often the more persistent problem because exposure is continuous. Outdoor mold levels fluctuate with weather conditions. Indoor mold from water damage continues to grow and release spores until it is physically removed. Patients with hidden indoor mold sources often experience symptoms that do not improve even when they stay inside.

Can mold grow in my air conditioner in South Florida? Yes, and this is a common problem in our climate. HVAC systems that run frequently in humid conditions can accumulate mold in the coils, drain pans, and ductwork. If you notice a musty smell when your air conditioning runs or if your symptoms are worse indoors than outdoors, having your system professionally inspected and cleaned is a reasonable first step.

Does allergy medication help with mold allergies? Antihistamines and nasal steroid sprays can help manage mold allergy symptoms, but they do not address the underlying sensitivity. For patients with persistent or severe mold allergy, allergen immunotherapy offers a longer-term solution by gradually reducing the immune system's reactivity to mold spores.

What mold species are most common in Palm Beach County? The most commonly problematic outdoor molds in South Florida include Alternaria, Cladosporium, and Aspergillus. After flooding or water damage, Stachybotrys (often called black mold) and Penicillium are frequently found indoors. Allergy testing can identify which specific species your immune system is reacting to.

Should I leave my home after a hurricane if I have mold allergies? If there has been significant water intrusion or visible mold growth, temporarily relocating during remediation is worth considering, particularly for patients with severe mold allergy or poorly controlled asthma. If relocation is not possible, maximizing air filtration, keeping windows closed, and working with your allergist on a medication plan for the exposure period can help manage symptoms.

If your allergies or asthma seem to flare every time it rains or after a storm, mold may be playing a bigger role than you realize. Call our Jupiter office at (561) 510-7232 or book online here to schedule an appointment with Dr. Jacobs.

Penicillin Allergy Testing: Myths, Risks, and Why It Matters

Sun, 14 Jun 2026 13:44:28 GMT

Key Points

Up to 90% of people who believe they are allergic to penicillin are not actually allergic when formally tested
Carrying an inaccurate penicillin allergy label leads to the use of broader, less effective antibiotics with more side effects
Penicillin skin testing is safe, quick, and can confirm or clear a penicillin allergy label in a single visit

If your medical chart says you are allergic to penicillin, there is a good chance that label is wrong. Research consistently shows that up to 90 percent of patients who report a penicillin allergy are not actually allergic when they undergo formal testing. That is not a small rounding error. It is one of the most widespread medical misclassifications in the country, and it has real consequences for your health every time you need an antibiotic.

Understanding where the label comes from, why it is so often inaccurate, and what it takes to clear it is worth your time.

Where Does the Penicillin Allergy Label Come From?

Most penicillin allergy labels originate in childhood. A child takes amoxicillin (a common penicillin-type antibiotic) for an ear infection and develops a rash. A parent reports the rash to the doctor. The allergy gets recorded in the chart and follows that person for the rest of their life.

The problem is that many of those childhood rashes had nothing to do with the antibiotic. Viral infections, which are often what children have when antibiotics are prescribed, commonly cause rashes on their own. A child with a viral illness who also happens to be taking amoxicillin may develop a rash from the virus, not the medication. But the timing creates a logical connection that is hard to ignore in the moment, and the allergy label gets added.

Other common sources of inaccurate penicillin allergy labels include mild side effects like nausea or stomach upset that were recorded as allergic reactions, reactions to a different antibiotic that was grouped under the penicillin label, and family members telling patients they had a reaction as a child that the patient has no memory of.

Over time, even if a true penicillin allergy existed, it often fades. Studies show that approximately 80 percent of people with a confirmed penicillin allergy lose that sensitivity within 10 years. Someone who genuinely reacted to penicillin at age seven may have no allergy whatsoever by adulthood, but the label in their chart never gets updated.

Why the Label Matters More Than You Might Think

Carrying a penicillin allergy label changes how you are treated medically, often in ways that put you at a disadvantage.

Penicillin and related antibiotics (the penicillin class, also called beta-lactam antibiotics) are among the most effective, best-studied, and well-tolerated antibiotics available. When a doctor sees a penicillin allergy in your chart, they switch to alternative antibiotics. Those alternatives are often broader spectrum, meaning they kill a wider range of bacteria including ones your body needs, which increases the risk of side effects like gastrointestinal problems and secondary infections. Some alternatives are simply less effective against the specific bacteria being treated.

At a population level, over-reliance on broad-spectrum antibiotics is one of the drivers of antibiotic resistance, a growing public health concern. At an individual level, patients with penicillin allergy labels have been shown in research to have longer hospital stays, higher rates of certain infections, and worse outcomes in some surgical settings compared to patients who can receive penicillin-class antibiotics.

The stakes get even higher in specific situations. If you ever need surgery, a serious infection, or treatment during pregnancy, your antibiotic options matter enormously. Carrying an allergy label that should not be there limits those options unnecessarily.

What Penicillin Skin Testing Actually Involves

Penicillin skin testing is a straightforward procedure that can confirm or clear a penicillin allergy label in a single office visit for most patients.

The test works similarly to standard environmental allergy skin testing. Small amounts of penicillin protein extracts are applied to the skin, either through a prick test on the forearm or a small intradermal injection just below the skin's surface. If your immune system has a true IgE-mediated sensitivity to penicillin (the type of reaction that causes hives, swelling, or anaphylaxis), a localized reaction will appear at the test site within about 15 to 20 minutes.

If the skin test is negative, which it is for the large majority of patients tested, the next step is typically a supervised oral amoxicillin dose given in the office. This is called an oral challenge. You take the medication and are monitored for 30 to 60 minutes. If no reaction occurs, the allergy label can be formally removed from your chart.

The entire process is done under medical supervision with appropriate precautions in place. Serious reactions during penicillin skin testing are rare, and the testing environment is equipped to manage them if they occur.

Who Should Consider Penicillin Allergy Testing?

If your chart carries a penicillin allergy label and you are not certain where it came from, or if the original reaction was a mild rash or stomach upset rather than a serious allergic response like hives, throat swelling, or anaphylaxis, penicillin skin testing is worth discussing with an allergist.

It is particularly worth pursuing before a planned surgery, if you have a condition that may require antibiotic treatment in the future, if you have had repeated courses of broad-spectrum antibiotics with significant side effects, or if you are pregnant or planning to become pregnant.

Children can also be tested. In fact, clearing an inaccurate penicillin allergy label early in life prevents decades of unnecessary antibiotic restrictions during some of the most medically active years.

What Happens If the Test Is Positive?

A positive penicillin skin test confirms a true IgE-mediated penicillin allergy. In that case, penicillin-class antibiotics should be avoided, and your doctor will work with other antibiotic options when treatment is needed.

For patients with confirmed penicillin allergy who require a penicillin-class antibiotic for a specific serious infection where no alternatives are appropriate, a process called drug desensitization may be possible. This is a specialized procedure performed in a controlled setting and is separate from standard allergy testing. It is not appropriate for routine situations but can be a life-saving option in the right clinical context.

For most patients, though, the result of penicillin skin testing is a negative test, a successful oral challenge, and the permanent removal of a label that should never have been there.

Frequently Asked Questions

Is penicillin skin testing safe? Yes. Penicillin skin testing is performed under medical supervision with appropriate safety measures in place. The amounts of allergen used are very small, and serious reactions are rare. The risk of leaving an inaccurate allergy label in place over a lifetime of medical care is generally considered greater than the very low risk associated with testing.

How long does penicillin allergy testing take? Plan for approximately one to two hours. This includes the skin test itself, the waiting period for results, and the supervised oral amoxicillin challenge if the skin test is negative. Most patients are able to complete the full evaluation and receive a definitive answer in a single visit.

Do I need to stop any medications before penicillin skin testing? Antihistamines should be stopped before testing, as they can suppress skin test reactions and produce false negative results. The office will give you specific guidance on which medications to pause and for how long based on what you are currently taking.

Can a penicillin allergy develop later in life even if I tolerated it before? Yes, though it is uncommon. Allergies can develop at any age with repeated exposure. If you tolerated penicillin in the past but had a concerning reaction more recently, that reaction should be evaluated. Skin testing can help clarify whether a true allergy has developed.

Will my insurance cover penicillin allergy testing? Most major insurance plans cover penicillin skin testing when it is medically indicated. Coverage varies by plan, so contacting your insurance company in advance to confirm your benefits is always a good idea. Our office can assist with insurance questions during scheduling.

What is the difference between a penicillin allergy and a penicillin intolerance? A true penicillin allergy involves an immune system response, typically IgE-mediated, that can cause hives, swelling, difficulty breathing, or anaphylaxis. An intolerance involves unpleasant but non-immune side effects like nausea, diarrhea, or stomach cramps. Intolerances are not true allergies and do not require avoiding the medication entirely, though they are frequently mislabeled as allergies in medical records.

If your chart says penicillin allergy and you are not sure the label is accurate, it is worth finding out. Call our Jupiter office at (561) 510-7232 or book online here to schedule an appointment with Dr. Jacobs.

Fall & Winter Asthma in South Florida: Why Symptoms Flare—and How to Stay in Control

Wed, 04 Mar 2026 18:44:52 GMT

If you’ve noticed that your (or your child’s) asthma seems to act up when school starts and the weather changes, you’re not imagining it. Even in sunny South Florida, fall and winter bring unique asthma challenges. This blog explains why symptoms flare this time of year and what patients can do to better control their asthma.

Why asthma often gets worse in the fall

In our region, the fall spike in asthma is driven by allergens shifting (ragweed, outdoor molds), respiratory viruses (RSV, influenza, COVID-19), and increased indoor air exposures (dust mites, pet dander, mold).

South Florida allergen snapshot in fall and early winter

Weeds like ragweed dominate late summer through fall. Outdoor molds thrive after rain and yard work. Trees and grasses have different peaks but can overlap.

What patients can do—our fall/winter asthma game plan

A five-pillar control plan: vaccines, consistent controller medication, allergen avoidance, indoor air quality strategies, and a personalized Asthma Action Plan.

Special tips for families with school-age kids

Make sure schools have updated action plans and inhalers, pre-treat before sports if needed, practice hand hygiene, and prioritize sleep.

Adults: don’t neglect these stealth triggers

Hidden asthma triggers in adults include dust mites in the bedroom, workplace exposures, heartburn, obesity, and sleep apnea.

Ragweed & weed pollens: how to live your life without hiding inside

Use pollen forecasts, shower/change after exposure, and stay consistent with allergy medications during ragweed season.

Mold: the fall spoiler we can actually manage

Bag leaves, dry water-damaged materials quickly, and keep indoor humidity between 30–50% to prevent mold growth.

Viruses: set yourself up for a gentler season

Get flu shots early, keep COVID-19 vaccinations current, ask about RSV prevention, and have an asthma sick-day plan.

When to call us (or go to urgent care)

Seek care if you’re using your rescue inhaler more than every 4 hours, having frequent night symptoms, or showing red zone asthma signs like difficulty speaking or blue lips.

Checklist: your Fall & Winter Asthma Kit

Asthma action plan, updated inhalers and spacers, vaccines, HVAC filters, humidity monitor, saline rinses, and school/sports kits.

Our approach at Allergy and Asthma Specialists of the Palm Beaches

We provide personalized testing, action plans, environmental coaching, and virus-season strategies to keep patients in control.

Bottom line

Fall and winter bring more asthma triggers, but with the right plan—vaccinations, controller therapy, allergen management, and environmental strategies—patients can stay well controlled.

Penicillin Allergy: Myths, Risks, and Why Testing Can Change Your Health

Wed, 04 Mar 2026 18:39:10 GMT

Did you know that 1 in 10 Americans report having a penicillin allergy—but fewer than 1% of people are truly allergic? That means the vast majority of patients who carry a 'penicillin allergy' label have either outgrown their allergy, never had a true allergic reaction, or were misdiagnosed in the first place.

Unfortunately, that inaccurate label can follow you for years, affecting which antibiotics you can take, the cost of your treatments, and even your risk of complications in the hospital.

At Allergy and Asthma Specialists of the Palm Beaches, we believe in getting the story right. This blog explains why penicillin allergies are often incorrect, what testing and “challenge” procedures involve, and how finding out the truth can improve your health and safety.

Why So Many People Are Labeled “Penicillin Allergic”

Childhood rashes, side effects mistaken for allergy, outgrowing the allergy, and miscommunication in medical records are the most common reasons patients are mislabeled.

The Risks of Carrying a False Penicillin Allergy Label

Fewer antibiotic choices, more expensive alternatives, higher risks of side effects and infections, longer hospital stays, and contribution to antibiotic resistance are major concerns.

What Does Penicillin Allergy Testing Involve?

Step 1: Careful history to clarify the original reaction.
Step 2: Skin testing with small doses under the skin. .
Step 3: Oral challenge with amoxicillin in a monitored clinic setting.

What Are the Benefits of Testing?

More effective antibiotics, lower costs, fewer complications, shorter hospital stays, and confidence in emergencies.

Are There Risks of Testing or Challenge?

Risks are very low: mild local skin reactions, rare hives, extremely rare systemic reaction (emergency treatment is on hand).

What Happens If You Are Truly Allergic?

We will document your allergy clearly, provide an action plan, discuss alternatives, and consider desensitization if penicillin is essential.

Why This Matters for Children

Children are often mislabeled because of viral rashes. Removing a false label early means access to safe first-line antibiotics and avoidance of unnecessary broad-spectrum alternatives.

Why This Matters for Adults

Adults often carry the label for decades. Testing can simplify treatment, reduce surgical risk, and improve hospital outcomes.

The Bigger Picture: Public Health Impact

Removing false penicillin allergy labels supports antibiotic stewardship, reduces resistance, and improves patient safety nationwide.

What to Expect at Our Clinic

Consultation and history review, skin testing, oral challenge, clear documentation, and patient education are the core steps.

Practical Take-Home Messages

Don’t assume your allergy is lifelong. Testing is safe, effective, and protects your health. Children especially benefit from early correction.

Conclusion

An allergy evaluation could give you back access to safe antibiotics, reduce risks, and improve your health for years to come. Don’t let an outdated label limit your care—schedule a consultation with Allergy and Asthma Specialists of the Palm Beaches.

Recurrent Itching (Pruritus): Why It Happens and How We Approach It in the Clinic

Wed, 04 Mar 2026 18:28:40 GMT

Everyone experiences an occasional itch. But when itching keeps coming back—especially if it’s widespread, intense, or interfering with sleep and quality of life—it’s called recurrent or chronic pruritus. For many people, itching is linked to obvious skin conditions like eczema, hives, or allergic rashes. For others, the skin looks completely normal, yet the sensation of itch persists.

As allergy, asthma, and immunology specialists, we often see patients who have been struggling with itching for months or even years. Sometimes they have tried multiple creams and antihistamines without relief. Our job in the clinic is not only to ease the discomfort, but also to search for hidden causes that may point to deeper health issues.

Why Recurrent Itching Matters

Itching may sound like a minor nuisance, but chronic pruritus affects quality of life almost as much as chronic pain. Patients often report sleep disturbance, anxiety, embarrassment, and skin infections from scratching. Medically, itching can signal conditions like liver disease, kidney disease, thyroid disorders, diabetes, iron deficiency, blood cancers, and neurologic or psychiatric causes.

Step One: Looking at the Skin

The first step in the clinic is examining the skin. If there are primary rashes—eczema, hives, nodules—the itch is likely dermatologic. If the skin looks normal (except for scratch marks), we think about systemic, neuropathic, or psychogenic causes.

Step Two: A Targeted Medical History

We ask about timing, distribution, associated symptoms, exposures, and stress levels. This holistic history helps us identify whether the itch is allergy-related, systemic, or influenced by psychological and social factors.

Step Three: Baseline Lab Work

If the cause isn’t obvious, we run baseline labs: CBC, iron studies, kidney function, liver panel, thyroid function, blood sugar, HIV and hepatitis screens. Sometimes we add special tests like protein electrophoresis or imaging.

Different Faces of Recurrent Pruritus

Pruritus may present with or without visible skin disease. We separate these two pathways to guide management.

Pruritus With Dermatitis (Skin Rash Present)
Conditions include eczema, contact dermatitis, hives, and prurigo nodularis. Treatments include moisturizers, topical steroids, antihistamines, and biologics like dupilumab and nemolizumab for severe cases.

Pruritus Without Dermatitis (Skin Looks Normal)
Causes include liver disease, kidney disease, blood disorders, thyroid disease, neuropathic itch, and psychogenic itch. Treatment involves addressing the underlying condition, using medications like gabapentin or antidepressants, and referring to specialists when necessary.

The Social and Emotional Side of Itching

Chronic itch disrupts sleep, affects mood, and increases depression risk. We validate our patients’ experiences and offer support through counseling, stress management, and community resources.

Self-Care and Lifestyle Strategies

Daily moisturizers, gentle cleansers, soft fabrics, short nails, cool compresses, and stress management all help reduce itching and prevent skin damage.

When to See a Doctor

Seek care if itching lasts more than 2–3 weeks, disrupts sleep, occurs with systemic symptoms, or does not respond to basic remedies.

How We Approach Recurrent Itching in Our Clinic

At Allergy and Asthma Specialists of the Palm Beaches, we provide a stepwise approach: history, exam, allergy testing, lab work, targeted treatments, collaboration with specialists, and emotional health support.

Conclusion

Recurrent pruritus may stem from allergies, skin disease, or systemic illness. With the right evaluation and care, relief is possible. Chronic itching is not something patients have to live with.
