How to stop a runny nose in 1 hour?
Cold medicines, like NyQuil™ SEVERE, will help dry up your nasal passages to help relieve your runny nose with an antihistamine. It also has a nasal decongestant to relieve your stuffy nose. If you want a soothing rush of Vicks Vapors with the same NyQuil relief, try Nyquil™ SEVERE + VapoCOOL™ Cold & Flu. There are several good options among antihistamines to dry up a runny nose, including diphenhydramine (Benadryl, Nytol), brompheniramine (Dimetapp Cold, Robitussin Cold & Allergy, Allergy Elixir), and doxylamine (Alka-Seltzer Plus Night-Time Cold Medicine, NyQuil).
