baby chest problems

My daughter of 9 months has had a very rattley chest and bad coughing episodes for about 6 weeks i have taken her to our doctor here 3 times first time she got given pred mix for 3days a few days after that was finished i took her back for the second time and she got given Keflor to have 2.5 ml twice daily until finished by the 6th day she was getting fevers and bad coughing episodes again so i took her back just for a checkup as i feel the meds weren't doing anything for her but he gave her the same medicine again for a further 5 days, we are about to finish the medicine tomorrow nite and she is starting to cough and is again getting fevers she has been quite drowsy and quiet for the past 2 days and as her mother i feel she is not getting any better - she is also taking medication for siezures - vigabatrin approx 45mg per kg or slightly less, i would just like to know what i could be doing to help her situation or what you would suggest to do
thanks
