My doc told me Claritin D, Zrytec D, Ocean spray Saline solution, and all natural cough drops (non-Menthol). Ive been drinking lemon and honey green tea. cooking with garlic and cinnamon more (good anti-virals)
Depends on the halls. Avoid the menthol as @natpirt mentioned. A sinus irrigation is a savior (nettipot or just a squeeze bottle) once in the am and once in the pm. Humidifiers, LOTS of fluid, Vicks, Tylenol (although I don't bother wasting my time because it really doesn't help me) are all great options.
