Therefore, this article will only discuss the newer antihistamines, as described below.
Newer antihistamines, called second-generation antihistamines include: It's important to note that montelukast (Singulair), is not an antihistamine, but rather an antileukotriene medication.
These antihistamines have significant side effects termed “anticholinergic” side effects, which may include dry mouth, sleepiness, constipation, and urinary retention.
Because of the side effects of these medications, they are generally considered to be too sedating for routine daytime use.
This results in simultaneous drug interaction whereby the central nervous system depression caused by the antihistamine is offset by the central nervous system stimulation caused by the caffeine.

Urticaria and angioedema lasting more than 6 weeks have been designated as chronic urticaria (CU).
It encompasses two major subtypes: chronic spontaneous urticaria (CSU) (previously known as chronic idiopathic urticaria) (CIU) and chronic inducible urticaria.
It must be noticed, however, that it is difficult to find clinical investigations that strictly follow the criteria recommended by the guidelines on the management of urticaria, and therefore studies included in this review were those in which higher doses of NSAHs were used regardless of the clinical response to conventional doses.
AHs included in this review are desloratadine, levocetirizine, fexofenadine, and the recently introduced NSAHs rupatadine and bilastine.
According to Humphreys and Hunter up to 40% of patients with CU may not achieve good control with antihistaminic therapy .
