However, you might not feel better for two to three days. Generally, these UTI treatments lasts about seven days. A number of previous studies have shown that short courses of 3 days of antibiotics are as effective as longer courses in uncomplicated UTI. A secondary aim was to investigate whether the likelihood of treatment failure varied between different antibiotics and, in the case of trimethoprim, the antibiotic most frequently prescribed for UTIs, between prescriptions of different duration.The study was carried out using the General Practice Research Database (GPRD), a computerized database of anonymized patient records drawn from a sample of representative general practices throughout the UK. On average, between 1992 and 1999, only 7.9% of trimethoprim prescriptions were for 3 days, 59.8% were for 5 days and 32.3% were for 7 days (Table 5The absolute risk of failure for 3, 5 and 7 days of trimethoprim treatment is shown in Table 6Not everyone diagnosed by a general practitioner with a UTI and treated with an antibiotic will necessarily have a bacterial infection. Of these, 509 patients (0.7%) had a previous record of diabetes and 4316 patients (5.7%) were pregnant at the time of the first treated infection.The 10 antibiotics most frequently associated with a diagnosis of UTI/cystitis are shown in Table 1Overall, 14% of patients required a further prescription for an antibiotic within 28 days of the initial prescription. Suitable data were not available to allow a similar analysis of recurrence rates.Patients prescribed amoxicillin are significantly more likely to return for a further course of antibiotics than those prescribed trimethoprim.

Antibiotics are often prescribed for viral illnesses that do not respond to other medication, or when patients do not take that medication properly. This class of bacteria are resistant to a lot of other antibiotics. It also depends on the type of infection you’re treating.Most antibiotics should be taken for 7 to 14 days. In each case the difference in failure rate was small and may be of little clinical significance. All diagnoses of UTI or cystitis with an associated prescription for an antibiotic were identified. Eventually, penicillin was produced in large quantities in a laboratory through fermentation using the fungus.Some other early antibiotics were produced by bacteria found in ground soil.Today, all antibiotic medications are produced in a lab. Failure rates were significantly greater for patients receiving cefalexin compared with those treated with co-trimoxazole, and there was no evidence that cefalexin was any more effective than trimethoprim (Table 3A number of previous studies have shown that short courses of 3 days of antibiotics are as effective as longer courses in uncomplicated UTI.This study was retrospective and patients were not randomized between treatments.
