This might be a flippant answer but don’t get one in the first place. Colds are caused by a virus and getting over them is mainly a function of immune system response, not drugs consumed. Yes, there are some anti-viral drugs but not for everyday use with the common cold. Sleep right, eat right. If you want drugs for symptom relief they are out there and they do work but you are not actually over the cold sooner. Zicam is a popular one.
