I am 66yo male .H/o diabetis for 15 yrs and blood glucose well controlled with insuli. I get recurrent kidney inf. Urine culture +ve for E.coli. I get better after 100mg Martifur bid for a week. However, Infection recurred after 4-5 months.It happened 3 times. A friend said that his doctor suggested to take maintainance dose of 100mg./day for 2-3 months. Is it safe to take for such alon period? Pl. advise  PC Shah.
Hayes it is fairly common practice to prescribe low dose antibiotics to prevent recurrent infections. I would advise changing the antibiotics according to frequent urine culture reports and if cultures are negative then continue the same antibiotic for a maximum of three months at lower dose. Using Arthur for more than three months is not recommended as it can cause liver problems. Switch over to another Chat Doctor.
