Brown urine is sometimes a symptom of a urinary tract infection, specifically a lower urinary tract infection, according to Healthline. In patients with a lower UTI, the urine may look like tea or cola.
Other symptoms of a lower UTI include a strong, persistent urge to urinate, passing frequent, small amounts of urine, and pain while urinating, according to Mayo Clinic. A patient's urine may also smell strong or foul. Women may experience pelvic pain, while men may experience rectal pain.
Treatment of UTIs usually consists of antibiotics, according to Mayo Clinic. Infections classified as simple infections usually respond to amoxicillin, ciprofloxacin, ampicillin or sulfamethoxazole-trimethoprim; however, the specific type of drug prescribed usually depends on the patient's health and the type of bacteria found in the urine. Symptoms usually clear up after a few days once treated; however, patients may need to continue taking antibiotics for a week or longer to ensure the infection has been treated entirely.
For people experiencing recurrences of UTIs, a longer course of antibiotics may be prescribed, states Mayo Clinic. Doctors may also recommend an at-home urine test to check periodically for infection as well as taking an antibiotic after sexual intercourse. Severe infections may require intravenous treatment at a hospital.
