Codeine / guaifenesin
cough
"My daughter and son were both prescribed this and it didn't work for either of them.  In fact, they both complained that it gave them a bad headache about an hour after taking it and they are both still coughing all night long.  Our pediatrician said this was just as good as Tussionex but much cheaper.  I'd rather pay $40 co-pay for the Tussionex since I know it works.  No relief for me or my children."
