Nursing friends can I take sudafed and Mucinex DM together? I was using claritin and sudafed but think I need Mucinex DM to dry this mess up. I dont want to OD. I also got night quil for cough and to help me sleep. What can I take to dry this stuff up. I am tried of coughing. I had a viral infection if that helps. The cough is so low that it is now causing my siatic nerve to shoot pain up my back and down my leg right after I cough. UcenterDress dress below the knee tea length
