I was prescribed Bramfed today, but the pharmacy was out of it and so the doctor s assistant called and said for me to get Robitussin DM because it was the same thing. After purchasing the Rob DM, I came home and realized that I ve been taking Mucinex DM which is the same thing, but is actually a little bit stronger. With that being said, the Mucinex hasn t really been working, so I don t think the Rob DM is going to either. Do you know if the Bramfed would have been more effective (my question mark isn t working on my keyboard). They didn t even swab me to see if had anything. They prescribed me antibiotics so I questioned if I had an infection and they said no we don t think you have an infection (even though I have been coughing up yellow and green phlegm). So I questioned why the antibiotics if there s no infection and the answer I was given was, well, it will help clear up whatever it is you have going on . I m just not sure if I should take the antibiotics if what I have is viral. I feel like today was such a waste of a visit and time. Please help. Thank you.
