Hello, I was born with one kidney. I recently moved. I have a new doctor and she informed me not to take any other meds. except regular tylenol. My question is am I able to take a cold and flu medicine? I generally don't get sick very often but, I am down with sneezing and coughing constently both day and night.Its been three years that I had a cold like this one. I need to get back to work. Can you please help with a little advice?
