Urinary tract infection (UTI) facts

  • Urinary tract infections (UTIs) are infections of the urethra, bladder, ureters, or the kidneys, which comprise the urinary tract.
  • E. coli bacteria cause the majority of UTIs, but many other bacteria, fungi, and parasites may also cause UTIs.
  • Females have a higher risk for UTIs than most males, probably because of their anatomy; other risk factors for UTIs include any condition that may impede urine flow (e.g., enlarged prostate, congenital urinary tract abnormalities, and inflammation). Patients with catheters or those who undergo urinary surgery and men with enlarged prostates are at higher risk for UTIs.
  • Symptoms and signs of UTI vary somewhat depending on sex, age, and the area of the urinary tract that is infected; some unique symptoms develop depending on the infecting agent.

Macrobid (nitrofurantoin monohydrate/macrocrystals) is an antibacterial drug used to treat urinary tract and bladder infections caused by Escherichia coli or Staphyloccocus saprophyticus strains of bacteria that are sensitive to this drug. The drug is available as a generic under the name nitrofurantoin. Macrobid should not be used for pyelonephritis (kidney infections) or other deep tissue infections such as perinephric abscesses. Common side effects are nausea, headaches and gas (flatulence).

Macrodid is available in 100 mg tablets for use in children >12 years old and adults. Macrobid should not be used in infants and its use in children <12 years old and pregnant females is not well documented. Lactating females should not use Macrobid. Infrequent but serious side effects include ulcerative colitis, pancreatitis, nystagmus, blood cell alterations and pulmonary complications such as pulmonary hypertension, swelling and short of breath. Some serious side effects appear only after long –term use of the drug. Also, chronic use to suppress urinary infections may allow other bacteria to proliferate and cause infections. Patients with blood or liver problems should avoid Macrobid use. Magnesium trisilicate, found in antacids reduces the adsorption of Macrobid.
