I started the 6 pack on Friday 2/3, I have had a major headache, face hurts, teeth hurt, coughing terribly, nose running. My Dr. Started me on this due to back pain and I've had wheezing. I have been taking allergy injection until last Aug. I've had serious family health issues and had to be out of state. Have taken Zyrtec every day. My understanding about methylprednisolone is that if a person has had an infection or come in contact with a contagious infection, that I could get it due to my immune system being down. This prednisolone has turned in the opposite direction for me. Would like to know if I can take this cough medicine until I can get in to my Dr. Thank you
