Are we on the right track in treating my girl?

Hi doctor,

My daughter, who is 4 years old, has got cold, cough and viral fever 3 weeks before. After a week of suffering, she was prescribed with Mucolite and Azithral antibiotic five day course of 5 mL one daily. When she was recovering, she started complaining of painful urination and abdomen pain. After a few days, we did a urine test and the result suggested infection with pus cell (4 to 6/hpf) and epithelial cell (0 to 2/hpf). For the past one week, her body temperature is usually about 98.5 to 99.3 degrees Fahrenheit and sometime it might get rise to 99.6 to 100 degrees Fahrenheit. The urine culture is in progress and will get the report in three to four days. The doctor has prescribed Disodium hydrogen citrate liquid, Cefixime oral suspension and Rinifol-Z (Lactic acid bacillus with vitamin and zinc) for the time being. My daughter was diagnosed for epilepsy this year and she is on Keppra. Online review shows that Disodium hydrogen citrate may cause seizure and muscle twitching as the side effect. I am really worried either to avoid it or give her the medicine. Are we on the right track in treating my girl? Is there anything wrong? She seems to get the cold again. It is just being two weeks now and she got cold again. Does she suffer from any other condition we need to diagnose further? She is almost sick for the last three weeks and we as parents are concerned about her epilepsy.

Please assist.

Thanks in advance.
