Allergy relief with nasal sprays
Nasal sprays can be an effective way of treating nasal allergies by delivering medication directly into the nose.
Decongestant nasal sprays can also help clear a blocked nose caused by hayfever, dust or pet allergies.
Allergy sprays contain different types of drugs that treat allergy symptoms. Some contain nasal steroids. Others contain antihistamines or anticholinergics. Other nasal sprays contain allergy medicines such as mast cell stabilisers.
How do nasal steroids give allergy relief?
Steroids are drugs that can be used in nasal allergy sprays. These allergy treatments help with the management of nasal symptoms from seasonal and year-round allergic and non- allergic rhinitis.
Steroid nasal sprays give allergy relief for all nasal allergy symptoms including congestion and discharge. They are not associated with significant side effects.
Nasal steroids give allergy relief by decreasing inflammation ( swelling) and mucus production. This action helps reduce the reaction of the nasal tissues to inhaled allergens. Nasal steroids can also treat nasal polyps that often cause obstruction and lead to nasal congestion and sinus infections.
How do other antihistamine and decongestant nasal sprays give allergy relief?
Decongestant nasal sprays give allergy relief for a swollen, congested nasal passage. A decongestant nasal spray may also relieve nasal swelling quickly without causing symptoms such as insomnia. However, decongestants should be used with caution in patients with high blood pressure and heart disease.
Antihistamines block the effect of histamine, a substance in the body that causes blocked and runny nose in hayfever.
An antihistamine nasal spray can treat allergy symptoms, including the runny nose, without causing as much drowsiness as an oral antihistamine might. Although sometimes sedation is a side effect with antihistamine nasal sprays, so use caution when driving.
It's best to use antihistamine nasal sprays before you're exposed to allergens to prevent sneezing, runny nose, and itchiness. Antihistamines are also effective for treating itchy eyes, sneezing, and itching.
Nasal sprays with mast cell stabilisers help prevent allergy symptoms such as runny nose or itchy eyes. These allergy drugs need several days to give good allergy relief and should be started up to one week before contact with allergens. They work by preventing the release of allergy symptom-causing chemicals such as histamine from mast cells. Leukotriene receptor antagonists are particularly useful for combination therapy when a person has asthma, as well as allergies. These drugs help block the chemicals in the body that promote inflammation.
Anticholinergics are a useful allergy treatment if you have a clear, watery discharge (rhinorrhoea) from the nose. These allergy drugs may work with antihistamines. Anticholinergic nasal sprays give relief from allergy symptoms by reducing a runny nose.
