Prevention of Kidney Infection
People who have frequent episodes of pyelonephritis or whose infection returns after antibiotic treatment is finished may be advised to take a small dose of antibiotic on a long-term basis to prevent recurrent infection. The ideal duration of such therapy is unknown. If the infection returns after stopping this antibiotic, preventive therapy may be continued indefinitely. If a woman of childbearing age is taking an antibiotic, she should avoid pregnancy or talk to her doctor about whether to use an antibiotic that is safe during pregnancy in case she becomes pregnant.
