You have prolonged fever for 20 days despite two antibiotics (Cuvibact = faropenem and levofloxacin), so I would not start another antibiotic empirically without identifying the cause.
Your blood culture has no growth at 48 hours, but it is still an interim report; the final report is expected after 5 days. Previous antibiotics can also make a blood culture negative.
Urine shows 8â10 RBC/HPF with 1+ blood, but no nitrite, leukocyte esterase or bacteriaâso this does not strongly suggest a UTI. Microscopic hematuria should be rechecked after the acute illness.
I would advise: CBC,
CRP/ESR,
LFT, RFT, malaria test, dengue testing as appropriate, and further evaluation based on symptoms/examination. Please see a physician/medicine specialist promptly, rather than taking another antibiotic blindly.
Next Steps
If fever is associated with breathing difficulty, severe headache, confusion, persistent vomiting, low BP, or severe weakness â urgent hospital evaluation.
