Antihistamines and sleep problems
Antihistamines, often used for relief of allergies, are sometimes prescribed to help people sleep. Examples of antihistamines are diphenhydramine hydrochloride (such as Benadryl) and doxylamine (such as Vicks Nyquil). Short-term improvements in insomnia have been noted with antihistamine treatment, but side effects may include daytime sleepiness, dizziness, mental sluggishness, and rapid heart rate.1
