Beta-lactams are arguably the most widely used and well-known antibiotics. This group includes penicillin and cephalosporins such as amoxicillin, Keflex, Duricef, Suprax and Ceftin, states RxList.

The appropriate antibiotic depends on the health condition requiring treatment, the kind of bacterium present in the urine, the susceptibility of the bacterium to the antibiotic, the severity of the infection and whether the patient is an adult, child or pregnant, explains RxList.

The family of tetracyclines, often prescribed for chlamydia infections, is unsafe for mothers and children, and includes minocycline and doxycycline, states RxList. Gentamicin and amikacin are forms of aminoglycosides, an antibiotic that doctors generally combine with other antibiotics in cases of severe UTIs.

Trimethoprim-sulfamethoxazole is a combination antibiotic sold under the names Bactrim DS or Septra. Like most antibiotics, it works best when administered in evenly spaced intervals, explains WebMD. WebMD recommends drinking 8 ounces of water with each dose of trimethoprim-sulfamethoxazole to avoid the formation of kidney stones.

Fluoroquinolones, such as the brand-name prescription antibiotic Levaquin, are broad-spectrum antibiotics safe for oral or intravenous administration, explains RxList.
