The first-line treatment options for allergic rhinitis in adults, according to current UK guidelines, are intranasal corticosteroids and antihistamines (intranasal or non-sedating oral antihistamines), used either alone or in combination NICE CKS.
Intranasal corticosteroids are considered the most effective treatment for allergic rhinitis NICE CKS.
Options include intranasal mometasone furoate, fluticasone furoate, or fluticasone propionate, which have minimal systemic absorption NICE CKS.
For mild, intermittent allergic rhinitis, an antihistamine (intranasal or oral non-sedating antihistamine) is suggested, especially in children, while any first-line treatment may be offered to adolescents and adults NICE CKS.
In cases of moderate to severe or persistent allergic rhinitis, an intranasal corticosteroid or a combination of intranasal corticosteroid with an intranasal antihistamine is recommended NICE CKS.
