Can I take another type of medicine while I'm taking penicillin?

Asked by babiturtle36 (2359) February 26th, 2009 from iPhone

It’s too early to call my doctor. I’m currently taking penicillin because I have strep throat. I have a cold, ( stuffy nose, cough, mucus ) can I take another medicine for my cold at the same time as the penicillin? If so, what medicine? Or should I just wait till I can call my doctor?
