Allergies & sinus problems
Stuffy for weeks: allergy, sinus infection, or the wrong spray?
About a quarter of adults have a seasonal allergy. Here is how to cut exposure, which medicines suit which symptoms, why decongestant sprays backfire after a few days, how to rinse your sinuses safely, and why most sinus infections clear without antibiotics.
In 30 seconds
The short answer
Allergies are common: in 2021, about a quarter of U.S. adults had a seasonal allergy.1 Breathing in pollen, mold, dander or dust makes the body release chemicals that cause symptoms.3 The best first step is reducing exposure,6 and nasal steroid sprays are the most effective treatment.8 Most sinus infections are viral and get better on their own without antibiotics.19

Choosing a medicine
| Medicine | Good for | Know this |
|---|---|---|
| Less-drowsy antihistamines (cetirizine, loratadine, fexofenadine) | Sneezing, itching, runny nose.12 | No alcohol; check how it affects you before driving.13 |
| Steroid nasal sprays | The most effective treatment for allergic rhinitis.8 | Work best used every day; can cause stinging or nosebleeds.811 |
| Decongestant nasal sprays | Short-term stuffiness. | No more than 3 days, or congestion rebounds.910 |
| Pseudoephedrine tablets | Stuffiness. | Tell your doctor first if you have high blood pressure or heart disease.15 |
Allergy shots can build tolerance over months to years.18

What the research says
- Hay fever and allergies often run in families.5
- Seasonal allergies can trigger or worsen asthma and lead to sinus and ear infections.17
- Allergy symptoms are often worst around 4 to 6 a.m.; a bedtime antihistamine may help mornings.14
- Unneeded antibiotics will not help, and their side effects can still cause harm.20
- Sinusitis lasting more than 12 weeks is chronic and needs a provider's assessment.31
From the Dr. Majid Ali archive
A historical perspective
“Allergy is a great masquerader of the immune system.”— Dr. Majid Ali, 2014-07-08Allergy was one of Dr. Ali's long-running subjects. He called it a great masquerader, argued that it was widely under-recognized, and put reducing exposure to triggers ahead of medicines.
Parts of that are consistent with current sources: allergies are common, affecting about a quarter of adults,1 and the best first treatment is to reduce exposure to what triggers your symptoms.6
Where ProperHealth stops. Dr. Ali also wrote that asthma, eczema, psoriasis, bowel diseases and other disorders are "in reality" caused by undiagnosed allergy, and explained allergy through his own "oxygen homeostasis" model. The sources used here do not support those claims. Allergy testing and diagnosis belong to a clinician.7
Medicines and safety
A pharmacist can help you match a medicine to your symptoms, check it against your other medicines and conditions, and show you how to use a nasal spray. A pharmacist does not diagnose allergies or sinus infections or prescribe antibiotics.
- Antihistamines: some cause less sleepiness, such as cetirizine, loratadine and fexofenadine.12 Avoid alcohol with them.13
- Steroid nasal sprays work best used every day;8 ask about a child using one more than two months a year.11
- Decongestant sprays: no more than 3 days.9
- Pseudoephedrine: tell your doctor first if you have high blood pressure, glaucoma, diabetes, prostate trouble, or thyroid or heart disease.15
- Children under 4: no over-the-counter cough and cold medicines unless a provider says so.24

What sprays, antihistamines and antibiotics do and do not do, what sets allergies off, and the non-drug steps with real evidence.
What conventional treatment does
- Nasal corticosteroid sprays are the most effective treatment for allergic rhinitis, and work best when used every day.8 Some antihistamines cause less sleepiness — cetirizine, desloratadine, fexofenadine, levocetirizine and loratadine;12 symptoms are often worst around 4 to 6 a.m., so a bedtime dose may help mornings.14 Allergy shots build tolerance with gradually increasing doses of the allergen.18
- Viruses cause most sinus infections, and most get better on their own without antibiotics;19 a provider may suggest watching and waiting 2 to 3 days before deciding on one.22
Limits and adverse effects
- A decongestant nose spray used for more than a few days can cause a rebound effect, making congestion worse;10 do not use one for more than 3 days.9 Steroid nasal sprays can cause stinging and nosebleeds; ask a professional if a child needs one for more than two months a year.11
- Pseudoephedrine can cause a fast or irregular heartbeat; tell your doctor first if you have high blood pressure, glaucoma, diabetes, prostate trouble, or thyroid or heart disease.15 Do not drink alcohol with antihistamines, and learn how one affects you before driving.13 When antibiotics are not needed they will not help, and their side effects can still cause harm.20 Do not give over-the-counter cough and cold medicines to children under 4 unless a provider says to.24
What contributes to the condition
- Breathing in an allergen such as pollen, mold, animal dander or dust makes the body release chemicals that cause symptoms.3 Hay fever and allergies often run in families.5 Hot, dry, windy days tend to have the most pollen; on cool, rainy days most of it is washed to the ground.4
- In 2021, 25.7% of U.S. adults had a seasonal allergy1 and 27.2% of children had at least one allergic condition.2 Seasonal allergies can trigger or worsen asthma and lead to sinus and ear infections.17
Integrative and naturopathic approaches, by evidence
Evidence levels: EstablishedEmergingHypothesisNot supported
- Established
The best treatment is to avoid the pollens that cause your symptoms; you may not avoid them all, but you can reduce exposure.6 Allergy testing, most often skin testing, can reveal what triggers your symptoms.7 Showering before bed removes allergens from skin and hair; stay indoors when symptoms are severe.16
- Established
Saline rinsing can remove dust and pollen and loosen thick mucus27 — but only with distilled, sterile or previously boiled water; tap water is not safe.25 Boil water 3 to 5 minutes, cool to lukewarm, use within 24 hours,26 and wash the device and let it dry between uses.28 A warm compress over the nose and forehead, and breathing steam, can ease sinus pressure.23

An allergy that comes with wheezing, or a sinus problem that lasts past 10 days, has moved beyond self-care; see the warning signs below.
When to get help now
Each warning sign cites the official guidance behind it. The wording still needs pharmacist sign-off.
- Trouble breathing, throat tightness, swelling of the face or lips, or collapse after a sting, food or medicine — use epinephrine if available and call 911.32
- Severe headache, a stiff neck, swelling or redness around the eye, or confusion with sinus symptoms — seek emergency care.3334
- Severe facial pain, or sinus symptoms lasting more than 10 days without improving — see a provider.35
- Wheezing or asthma that is getting worse during allergy season — contact your provider right away. Severe shortness of breath at rest, drowsiness or confusion — call 911.3637
- Fever, nosebleeds or headaches while using a nasal rinse — see your provider.38
