    ### Instruction:
    What are the treatments for Pyelonephritis: Kidney Infection ?
    ### Response:
    Pyelonephritis is treated with antibiotics, which may need to be taken for several weeks. While a urine sample is sent to a lab for culture, the health care provider may begin treatment with an antibiotic that fights the most common types of bacteria. Once culture results are known and the bacteria is clearly identified, the health care provider may switch the antibiotic to one that more effectively targets the bacteria.
