Detailed explanation-1: -Second-generation antihistamines were first developed in the 1980s. They cause less sleepiness than first-generation antihistamines and also interact with fewer medications. Some examples of second-generation antihistamines include: Cetirizine (Zyrtec)
Detailed explanation-2: -There are reports based on patient-rated questionnaires [19, 20] that show that even second-generation antihistamines, such as rupatadine and cetirizine, especially if up-dosed, lead to daytime sleepiness nonetheless.
Detailed explanation-3: -The most common side effect of cetirizine is feeling sleepy and tired. This happens in more than 1 in 10 people. Talk to your doctor or pharmacist if this side effect bothers you or does not go away.
