Antibiotics in Recurrent Urinary Infections

Physicians typically treat ordinary urinary tract infections with a short course of antibiotic therapy. For people with recurring infections, however, the antibiotic treatment plan may differ, ranging from long-term usage to a single dose.

Cause

• According to the Mayo Clinic, people who have recurrent urinary tract infections may have an impaired immune system that allows bacteria to more easily infect the urinary tract.

Types

• The types of antibiotics used to treat urinary tract infections include trimethoprim/sulfamethoxazole (Bactrim, Cotrim), nitrofurantoin (Furadantin) and cephalexin (Keflex).

Long-term Antibiotics

• Recurrent urinary tract infections can be treated with low doses of antibiotics over six or more months. The typical antibiotics used are trimethoprim/sulfamethoxazole or nitrofurantoin.

Short-term Antibiotics

• Alternatively, your doctor may prescribe a self-treatment plan, providing you with a supply of antibiotics. These antibiotics are to be used after the onset of future symptoms.

Single-dose Antibiotics

• Some doctors prescribe single-dose antibiotics, to be taken after sexual intercourse to prevent redevelopment of infections.

Warning

• Be sure to talk with your physician if you're planning to become pregnant or if you're taking oral contraceptives. Also, always take antibiotics as prescribed.
