@zscline Welcome to Mayo Connect.
Regarding antibiotics!, remember that colds are caused by a virus and antibiotics don't work on them, so the short answer would be No. But, with bad lungs, a cold can quickly give was to a bacterial infection, whether bronchitis, pneumonia or a sinus infection, and those will respond. Each person and their docs must wprk out a treatment plan that works.
Also, at the first sign of a cold, it is usually good to double up on airway clearance, get extra rest and eat well. I also add a sinus rinse to my protocol to help wash out the virus.
