Different actions: atarax or hydroxyzine is a first generation antihistamine, which works by suppressing the release of histamine, a transmitter which causes the symptoms of allergy. singulair, or montelukast works much earlier in the pathways for allergy, and tends not to have the sedating effects of hydroxyzine or diphenhydramine (benedryl). it is also effective in asthma.

Different Drugs: Singulair (montelukast) is a drug which blocks leukotrienes which are inflammatory chemicals made by your immune system in allergic reactions. Atarax blocks histamine.
