How to Treat Spring Allergies: Sprays, Pills & More

Spring allergies respond best to a layered approach: reducing your exposure to pollen, using the right over-the-counter medications at the right time, and for stubborn cases, considering longer-term treatments like immunotherapy. Most people can get significant relief without a prescription, but timing and consistency matter more than most realize.

Start Nasal Steroid Sprays Early

Over-the-counter nasal corticosteroid sprays (sold as Flonase, Nasacort, and Nasonex) are the single most effective treatment for spring allergy symptoms like congestion, sneezing, and a runny nose. They work by dialing down the inflammatory signals your nasal tissue produces when it contacts pollen. Over days of consistent use, the spray reduces swelling in your nasal passages and cuts down on mucus production.

The key detail most people miss: these sprays don’t work like decongestants. You won’t feel immediate relief. Maximum benefit takes several days of regular use, and individual response times vary. This is why allergists recommend starting your nasal spray one to two weeks before your typical allergy season begins, rather than waiting until you’re already miserable. If you know tree pollen wrecks you every March, start spraying in mid-February. Consistency is everything. Skipping days resets the clock.

Choose the Right Antihistamine

Oral antihistamines handle the itching, sneezing, and watery eyes that nasal sprays don’t fully cover. Second-generation options like cetirizine (Zyrtec), loratadine (Claritin), and fexofenadine (Allegra) are preferred because they cause far less drowsiness than older antihistamines like diphenhydramine (Benadryl). They work within one to two hours and last a full 24 hours per dose.

Each one has a slightly different profile. Cetirizine tends to be the most potent but is the most likely of the three to cause mild drowsiness. Fexofenadine is the least sedating. Loratadine falls in the middle. If one doesn’t seem to work well for you after a week or so, switching to another is a reasonable move since people respond differently. Taking your antihistamine at the same time every day, rather than only when symptoms flare, keeps a steady level in your system and prevents the allergic cascade from gaining momentum.

Treat Itchy Eyes Separately

If your eyes are the main battleground, oral antihistamines alone often aren’t enough. Over-the-counter allergy eye drops containing ketotifen (sold as Alaway and Zaditor) deliver relief directly where you need it. One drop in each affected eye twice daily, spaced 8 to 12 hours apart, blocks both the histamine response and the release of other inflammatory chemicals from cells in your eye tissue. This dual action makes ketotifen drops more effective for eye symptoms than oral antihistamines alone.

Avoid “redness relief” eye drops (like Visine Original) for allergies. These simply constrict blood vessels temporarily and can cause rebound redness with regular use. Look specifically for drops labeled for allergy or itch relief.

Rinse Pollen Out With Saline

Nasal saline irrigation, using a neti pot or squeeze bottle, physically flushes pollen grains out of your nasal passages. It’s drug-free, safe to combine with any medication, and provides near-immediate relief from congestion. Many people find rinsing after spending time outdoors significantly reduces their evening and nighttime symptoms.

Water safety matters here. Never use plain tap water for nasal rinsing. The CDC recommends using store-bought water labeled “distilled” or “sterile.” If you use tap water, bring it to a rolling boil for one full minute (three minutes if you live above 6,500 feet elevation), then let it cool completely before use. Stored boiled water should go in a clean, sealed container. These precautions prevent rare but serious infections from organisms that can survive in untreated tap water.

Reduce Pollen Exposure at Home

No medication works as well when you’re constantly re-exposing yourself to the allergen. A few changes to your routine can cut your indoor pollen load dramatically.

Pollen counts tend to be lowest between 4:00 a.m. and noon, then climb through the afternoon, peaking between 2:00 and 9:00 p.m. If you exercise outdoors or need to do yard work, mornings are your best window. On high-pollen days, keep windows closed during the afternoon and evening, even if the weather is pleasant.

HEPA air purifiers capture at least 99.97% of airborne particles, including pollen, at sizes down to 0.3 microns. Running one in your bedroom while you sleep can make a noticeable difference, since you spend roughly a third of your day there. Choose a unit rated for the square footage of the room. Changing clothes and showering after extended time outside also prevents you from carrying pollen onto furniture and bedding.

Watch for Pollen-Food Cross Reactions

If you notice your mouth or throat itching or tingling when you eat certain raw fruits or vegetables during allergy season, you’re likely experiencing pollen-food allergy syndrome. Your immune system confuses proteins in certain foods with the pollen proteins it’s already primed to attack. This is more common than most people expect.

The specific foods depend on which pollen triggers your allergies:

  • Birch pollen: apple, cherry, peach, pear, plum, kiwi, carrot, celery, almond, hazelnut
  • Grass pollen: celery, melons, oranges, peaches, tomato
  • Ragweed pollen: banana, cucumber, melons, sunflower seeds, zucchini

Cooking or heating these foods typically breaks down the proteins enough to prevent the reaction. So if a raw apple makes your lips tingle in April, applesauce or baked apples likely won’t. Symptoms are almost always mild and limited to the mouth and throat, but if you experience swelling beyond your mouth, difficulty breathing, or any full-body reaction, that signals a more serious food allergy that needs evaluation.

When OTC Treatments Aren’t Enough

If you’ve layered a nasal steroid, an antihistamine, and pollen avoidance strategies together for a full season and still feel miserable, immunotherapy is worth discussing with an allergist. It’s the only treatment that changes how your immune system responds to pollen rather than just managing symptoms.

Two forms are available. Allergy shots (subcutaneous immunotherapy) have been the standard for decades. You receive gradually increasing doses of your specific allergens via injection, typically weekly at first, then monthly for maintenance. The full course runs three to five years. Sublingual tablets, which dissolve under your tongue at home daily, are a newer alternative approved for specific allergens like grass and ragweed pollen.

Both approaches are effective for seasonal allergies. Meta-analyses comparing the two consistently show that allergy shots produce a somewhat larger reduction in symptoms, but sublingual tablets still deliver meaningful relief and don’t require regular office visits. The benefits of either form tend to persist for years after treatment ends, which distinguishes immunotherapy from every other allergy treatment. It’s a bigger time commitment upfront but can be the difference between dreading spring and barely noticing it.

Putting It All Together

The most effective approach for most people combines prevention with medication. Start a nasal steroid spray a couple of weeks before your season begins. Add a daily antihistamine once symptoms arrive. Use saline rinses after pollen exposure. Keep windows closed in the afternoon, run a HEPA filter in your bedroom, and shower before bed. Layer in allergy eye drops if your eyes are particularly affected. Each of these interventions is moderately helpful on its own, but stacked together, they typically provide substantial relief for even moderate-to-severe spring allergies.
