Urine test confirmed klebsiella pneumoniae. i am allergic to trimethoprim, so doctor prescribed fosfomycin 3g. i read it only should be taken by women above 50kg, i am 45kg. what to do? what alternative? i cannot reach my doctor.

Klebsiella UTI: Klebsiella is susceptible to several antibiotics and the lab probably tested for susceptibility to many. Ones that usually are active include amoxicillin/clavulanate, cephalexin (and other cephalosporins), ciprofloxacin (and other quinolones), and doxycycline (and other tetracyclines). All these are more likely to be active sulfa-trimethoprim. Discuss with your doctor. Good luck.
