What are the causes of sneezing allergy
Respiratory tract infections, such as the common freezing, can also cause sneezing.
Colds cause mucus production, which in turn stimulates various nerves within the nasal mucous membranes. Sneezing is an example of a symptom that makes it hard to tell the difference between symptoms of freezing compared to allergies.
In the case of a freezing, histamine is not causing the sneezing, so most antihistamines would not be expected to assist the symptom.
However, medications that can dry nasal secretions, including some antihistamines such as Benadryl, as well as anticholinergic nasal sprays such as Nasal Atrovent, can assist with sneezing.
When to see a GP
Visit a GP if the symptoms of allergic rhinitis are disrupting your sleep, preventing you carrying out everyday activities, or adversely affecting your performance at work or school.
A diagnosis of allergic rhinitis will generally be based on your symptoms and any possible triggers you may own noticed.
If the cause of your condition is uncertain, you may be referred for allergy testing.

Allergic Rhinitis and Sneezing
When you are allergic to something, you may sneeze.
Hay fever or allergy to pollen, mold, dander, or dust can own you running for the tissues. In allergic rhinitis, the allergic cells in your nasal mucous membranes release histamine. Histamine acts on various nerves within the nasal mucous membranes, which causes you to sneeze. It also causes other typical allergy-related problems, love a runny nose.
Antihistamines, in both oral and nasal forms, are often excellent treatment choices for sneezing caused by allergic rhinitis.
While they won't be helpful for most non-allergic causes, in the case of allergies they work against the histamine that is producing the sneezing and runny nose.
You should also take physical measures to reduce the allergens that are producing the reaction. These can include ensuring your furnace filters are clean, using air filters to reduce the quantity of pollen in the air, and washing your linens in boiling water to kill dust mites.
Nose and Eye Allergies
Symptoms of allergic rhinitis
Allergic rhinitis typically causes cold-like symptoms, such as sneezing, itchiness and a blocked or runny nose.
These symptoms usually start soon after being exposed to an allergen.
Some people only get allergic rhinitis for a few months at a time because they’re sensitive to seasonal allergens, such as tree or grass pollen.
Other people get allergic rhinitis every year round.
Most people with allergic rhinitis own mild symptoms that can be easily and effectively treated.
But for some people symptoms can be severe and persistent, causing sleep problems and interfering with everyday life.
The symptoms of allergic rhinitis occasionally improve with time, but this can take numerous years and it’s unlikely that the condition will vanish completely.
Irritants and Other Sneezing Triggers
Remember those ancient cartoons when black pepper was used to launch a character into a sneezing attack? Black pepper acts as a chemical irritant on the nerves in the nasal mucosa, which causes sneezing.
Other chemical irritants that cause sneezing include strong odors, perfumes, and tobacco smoke; these triggers cause non-allergic rhinitis since there are no allergic antibodies causing the symptoms.
Physical irritants such as bright sunlight can also cause sneezing, which is called the nasoocular reflex.
This involves a reflex connection between the eyes and nose, which causes stimulation of nerves within the nasal mucous membranes, resulting in sneezing.
For treating this problem, chemical and physical irritants do not cause sneezing through the release of histamine, so traditional antihistamines would not be expected to treat symptoms caused by these irritants.
Instead, various nasal sprays, including nasal steroids, some nasal antihistamines, and anticholinergic nasal sprays may be helpful for treating sneezing caused by chemical and physical irritants.
Allegra (fexofenadine) has emerged as a leading "non-drowsy" antihistamine for people with allergic rhinitis.
Bilaxten (bilastine) is a longer-lasting and even less sedating antihistamine option but is not yet approved for use in the United States.
Antihistamines combined with decongestants, analgesics, or both appear to own a little to moderate effect on freezing symptoms in older children and adults, according to a 2014 study in the Canadian Medical Association Journal.
Intranasal corticosteroids are first-line therapy for chronic non-allergic rhinitis. Fluticasone propionate (sold under the brand names Flovent and Flonase) and Qvar (beclomethasone) are the only topical corticosteroids approved for non-allergic rhinitis.

Allergic rhinitis is inflammation of the inside of the nose caused by an allergen, such as pollen, dust, mould or flakes of skin from certain animals.
It’s a extremely common condition, estimated to affect around 1 in every 5 people in the UK.
What causes allergic rhinitis
Allergic rhinitis is caused by the immune system reacting to an allergen as if it were harmful.
This results in cells releasing a number of chemicals that cause the inside layer of your nose (the mucous membrane) to become swollen and too much mucus to be produced.
Common allergens that cause allergic rhinitis include pollen (this type of allergic rhinitis is known as hay fever), as well as mould spores, home dust mites, and flakes of skin or droplets of urine or saliva from certain animals.
