The fastest way to soothe allergies is to combine two strategies: reduce your exposure to the trigger and block your body’s inflammatory response with the right medication. Most people rely on just one approach, but layering several together is what actually keeps symptoms under control through an entire allergy season.
When your body encounters an allergen like pollen, dust, or pet dander, your immune system releases histamine and other inflammatory chemicals from specialized cells called mast cells. Histamine is what causes the sneezing, itchy eyes, runny nose, and congestion you feel. Every strategy below works by either lowering the amount of allergen reaching your body or interrupting that inflammatory chain.
Pick the Right Over-the-Counter Medication
Nasal steroid sprays are the single most effective over-the-counter option for allergic rhinitis. U.S. allergy guidelines recommend them as first-line treatment because they reduce congestion, sneezing, and itching all at once, and they work faster and more completely than pills for moderate to severe symptoms. You’ll find them labeled as fluticasone or triamcinolone at the pharmacy. They take a day or two to reach full effect, so starting them before your worst season hits makes a real difference.
Oral antihistamines like cetirizine (Zyrtec), loratadine (Claritin), and fexofenadine (Allegra) are better for mild symptoms, especially itchy eyes, sneezing, and a runny nose. They’re less effective at relieving stuffiness. Adults typically take cetirizine 10 mg once daily, loratadine 10 mg once daily, or fexofenadine 180 mg once daily. All three are non-drowsy for most people, though cetirizine causes sleepiness more often than the other two.
For stubborn symptoms, you can use a nasal spray and an oral antihistamine together. Nasal antihistamine sprays like azelastine are another option that works faster than pills and targets nasal symptoms more directly. If one combination isn’t cutting it after a week or two of consistent use, that’s a sign you may need a different approach rather than just more of the same medication.
Clean Your Indoor Air
A HEPA air purifier in your bedroom can trap 99.97% of airborne particles as small as 0.3 microns, according to the EPA. That’s small enough to capture pollen, pet dander, dust mite debris, and mold spores. Place one where you sleep, since you spend roughly a third of your day there. Keep windows closed during high-pollen days and run the purifier continuously on a low setting rather than turning it on only at night.
If you have forced-air heating or cooling, upgrading to a MERV 11 or higher furnace filter helps catch allergens before they circulate through your home. Change it every one to three months during allergy season.
Rinse Your Sinuses Safely
Nasal saline irrigation, whether with a neti pot, squeeze bottle, or powered irrigator, physically flushes pollen and mucus out of your nasal passages. You can do it as many times a day as you need. It’s especially helpful before bed, when congestion tends to worsen.
The one critical safety rule: never use plain tap water. Tap water can contain bacteria and amoebas that are harmless when swallowed but potentially dangerous, even fatal in rare cases, when introduced into nasal passages. The FDA recommends using only distilled water, sterile water, or tap water that has been boiled for 3 to 5 minutes and cooled. Previously boiled water stays safe in a sealed container for up to 24 hours. Water passed through a filter specifically designed to trap infectious organisms also works.
Build an Allergy-Proof Nighttime Routine
Allergy symptoms often peak at night because you’ve been collecting pollen on your skin, hair, and clothes all day, then lying down in it. A few habit changes can dramatically improve how you sleep.
Shower before bed, or at least after spending time outdoors. This washes pollen off your skin and hair before it transfers to your pillow. The steam also helps loosen congestion. If you can’t wash your hair every night, wearing a sleep bonnet keeps pollen contained and off your bedding.
Wash your sheets, pillowcases, and blankets weekly in hot water. Handle dirty bedding gently to avoid launching allergens into the air as you strip the bed. Running a HEPA purifier in the bedroom while you sleep adds another layer of protection. And rinsing your sinuses right before you lie down clears out whatever you’ve inhaled during the day, so you’re not breathing through swollen passages all night.
Watch for Food Cross-Reactions
If raw fruits or vegetables make your mouth tingle or itch during allergy season, you’re likely experiencing oral allergy syndrome. Your immune system mistakes proteins in certain foods for the pollen you’re allergic to, triggering a mild reaction in your mouth and throat. This affects up to a third of people with pollen allergies.
The specific foods depend on your pollen trigger:
- Birch pollen: apples, cherries, peaches, pears, plums, carrots, celery, almonds, hazelnuts, kiwi, soy
- Ragweed pollen: bananas, cantaloupe, honeydew, watermelon, cucumber, zucchini, chamomile tea
- Grass pollen: tomatoes, melons, oranges, figs
Cooking or peeling these foods usually breaks down the problematic proteins enough to eliminate the reaction. If you notice tingling with raw versions, try them heated or processed instead of avoiding them entirely.
Supplements That May Help
Quercetin, a plant compound found in onions, apples, and berries, has shown promise as a supplement for allergy relief. It appears to stabilize the cells that release histamine, reducing symptoms at the source. A 2023 clinical trial found that adding a quercetin-based supplement to standard allergy treatment led to 39% greater symptom improvement over three months compared to medication alone. A 2025 study confirmed that quercetin combinations outperformed antihistamines by themselves over a similar timeframe.
That said, there’s no standardized dose for humans yet, and quercetin works best as an add-on to your other strategies rather than a replacement. Look for supplements that combine quercetin with bromelain, which may improve absorption.
Immunotherapy for Long-Term Relief
If your allergies are severe or last many months of the year, immunotherapy is the only treatment that can retrain your immune system to stop overreacting. It comes in two forms: allergy shots (given at a doctor’s office) and sublingual tablets or drops (dissolved under the tongue at home). Both require a commitment of at least one to two years, with many treatment plans extending to three years for lasting results.
Research comparing the two approaches in head-to-head studies shows they produce similar symptom relief and similar reductions in medication use. The main difference is safety: sublingual immunotherapy has a significantly lower rate of side effects than shots. Shots carry a small risk of a systemic reaction, which is why they’re always administered in a medical office. Sublingual therapy is convenient for people who can’t make frequent office visits, since you take it daily at home after the first dose.
Both forms can also reduce the risk of developing new allergies and may prevent allergic rhinitis from progressing to asthma over time. If you’ve been managing symptoms for years without real improvement, immunotherapy is worth discussing with an allergist because it targets the underlying problem rather than just masking symptoms season after season.
