Allergies rarely show up as just one symptom. If you’re dealing with a mix of congestion, sneezing, runny nose, itchy eyes, and sinus pressure, the right over-the-counter (OTC) combo can make a big difference. Here are 10 evidence-based OTC options and how to match them to your symptoms safely.

Note: This article is educational and not a substitute for medical advice. Check labels, use as directed, and ask a clinician or pharmacist if you have health conditions, are pregnant, or take other medicines.

  1. Intranasal corticosteroid sprays (best all-around control)
  • What they help: Nasal congestion, runny nose, sneezing, itching; can lessen eye symptoms for some.
  • Examples: Fluticasone propionate (Flonase), fluticasone furoate (Flonase Sensimist), triamcinolone (Nasacort), budesonide (Rhinocort).
  • Why they’re first-line: Clinical guidelines consider them the most effective single therapy for allergic rhinitis across symptoms, especially congestion (Rhinitis 2020 practice parameter) AAAAI.
  • How to use: Daily, not just as needed. Full effect builds over several days; technique matters (aim nozzle slightly outward, away from the septum).
  • Watch-outs: Nosebleeds/irritation possible. Generally safe long-term at OTC doses; ask a clinician for kids or prolonged use ACAAI.
  1. Second-generation oral antihistamines (fast relief for itch/sneeze/drip)
  • What they help: Sneezing, itchy nose/throat/eyes, runny nose; less helpful for congestion.
  • Examples: Cetirizine (Zyrtec), levocetirizine (Xyzal), fexofenadine (Allegra), loratadine (Claritin).
  • Why choose them: Effective for histamine-driven symptoms with less drowsiness than older antihistamines ACAAI.
  • How to use: Once daily for steady control; fexofenadine works best when taken with water (not fruit juice).
  • Watch-outs: Cetirizine/levocetirizine can cause drowsiness in some. Avoid combining multiple antihistamines unless advised.
  1. Intranasal antihistamine sprays (quick, targeted nose relief)
  • What they help: Nasal congestion, runny nose, sneezing, and itching; often faster onset than intranasal steroids.
  • Example: Azelastine (Astepro) is now available OTC in the U.S. FDA.
  • Why consider: Useful as monotherapy or add-on to a nasal steroid when symptoms break through AAAAI.
  • How to use: 1–2 sprays per nostril as directed; benefits can start within minutes.
  • Watch-outs: Bitter taste and mild drowsiness can occur.
  1. Oral antihistamine + decongestant combos (for congestion plus itch/sneeze)
  • What they help: Combines antihistamine benefits with decongestant relief.
  • Examples: Loratadine + pseudoephedrine (Claritin-D), cetirizine + pseudoephedrine (Zyrtec-D), fexofenadine + pseudoephedrine (Allegra-D).
  • Evidence note: Pseudoephedrine has decongestant efficacy; the FDA advisory committee concluded in 2023 that available data do not support effectiveness of oral phenylephrine for nasal congestion FDA advisory committee meeting.
  • How to use: Daytime formulas usually contain non-drowsy antihistamines; “-D” indicates a decongestant.
  • Watch-outs: Pseudoephedrine can raise blood pressure/heart rate and cause insomnia; it’s sold “behind the counter” in many states. Avoid if you have certain heart conditions unless approved by your clinician MedlinePlus.
  1. Standalone oral decongestants (target stubborn nasal blockage)
  • What they help: Short-term nasal and sinus congestion.
  • Example: Pseudoephedrine.
  • Why use: Useful for short bursts (e.g., high-pollen days) when congestion dominates.
  • How to use: Short courses at the lowest effective dose.
  • Watch-outs: Same cautions as above; avoid near bedtime. Be cautious with thyroid disease, glaucoma, prostate enlargement, and certain antidepressants; ask a clinician or pharmacist MedlinePlus.
  1. Ketotifen allergy eye drops (itchy, watery eyes)
  • What they help: Ocular itching, tearing, redness from allergic conjunctivitis.
  • Examples: Ketotifen 0.025% (Zaditor, Alaway, generics); some olopatadine strengths are OTC, too.
  • Why choose: Dual-action antihistamine and mast cell stabilizer; fast and lasts 8–12 hours MedlinePlus.
  • How to use: 1 drop in affected eye(s) twice daily as directed; remove contacts before use.
  • Watch-outs: Don’t mix with “redness-relief only” drops that lack antihistamine activity.
  1. Saline nasal irrigation or sprays (rinse allergens, thin mucus)
  • What they help: Congestion, postnasal drip, and nasal irritation by mechanically flushing allergens.
  • Forms: Isotonic saline sprays; squeeze-bottle or neti pot rinses with sterile/distilled water.
  • Evidence: Can improve symptoms and quality of life for rhinitis/sinus issues when used correctly ENT Health (AAO-HNS).
  • How to use: Daily or as needed; always use distilled/sterile or properly boiled-and-cooled water.
  • Watch-outs: Poor water hygiene can lead to serious infection risk; follow device instructions.
  1. Intranasal cromolyn (prevention-focused)
  • What it helps: Prevents allergic nasal symptoms by stabilizing mast cells.
  • Example: Cromolyn sodium (Nasalcrom).
  • Why use: Very safe and non-drowsy; best when started before allergen exposure and used several times daily MedlinePlus.
  • How to use: 1 spray per nostril 3–4 times daily during allergy season.
  • Watch-outs: Requires frequent dosing; onset is slower than antihistamines/steroids.
  1. Topical nasal decongestant sprays (very short-term rescue)
  • What they help: Rapid relief of severe congestion.
  • Examples: Oxymetazoline (Afrin), phenylephrine nasal sprays.
  • How to use: Up to every 10–12 hours (oxymetazoline) for no more than 3 days.
  • Watch-outs: Longer use can cause rebound congestion (rhinitis medicamentosa) MedlinePlus.
  1. “Multi-symptom” allergy formulas (convenient—but read the Drug Facts)
  • What they help: Combine several actives to cover multiple symptoms (e.g., antihistamine + decongestant ± pain reliever).
  • Why consider: One pill or liquid can simplify dosing when you truly need all included ingredients.
  • Watch-outs:
    • Check the Drug Facts label to avoid duplicate ingredients (e.g., taking a combo plus a separate antihistamine) FDA Drug Facts Label.
    • Many combos rely on oral phenylephrine for “congestion,” which an FDA advisory committee concluded is not effective as an oral decongestant; choose products with pseudoephedrine if decongestant therapy is appropriate for you FDA advisory committee meeting.

How to combine safely for multi-symptom relief

  • Start with an intranasal corticosteroid for daily control if nasal symptoms persist through the season.
  • Add a second-gen oral antihistamine for itch/sneeze/runny nose days.
  • For breakthrough congestion, consider short-term pseudoephedrine or a brief course of topical oxymetazoline (max 3 days).
  • Eye symptoms? Add ketotifen drops.
  • Rinse with saline once daily to reduce allergen load and improve comfort.
  • Avoid stacking multiple antihistamines or multiple decongestants. Always read the Drug Facts label and ask a pharmacist if unsure FDA.

When to see a clinician

  • Daily symptoms >2–4 weeks despite optimized OTC use.
  • Severe congestion, recurrent sinus infections, or asthma symptoms.
  • Children, pregnancy, high blood pressure, heart disease, glaucoma, thyroid disease, prostate enlargement, or significant medication interactions.
  • Considering allergen immunotherapy (shots or prescription tablets) for long-term control.
