The fruit produced by the Vaccinium macrocarpon plant is tart but tasty and is used as a medicinal supplement. Using cranberry tablets may help prevent bladder infections. This supplement works by preventing a particular type of bacterium -- called Escherichia coli, or E. coli, from adhering to the walls of the bladder. Despite these benefits, you should talk with your doctor before using cranberry tablets for a bladder infection.
Warning
Although daily treatment with cranberry tablets may help prevent the onset of a bladder infection, cranberry tablets shouldn't be used as a substitute for antibiotics if you have an active bladder infection. In the absence of an appropriate antibiotic treatment, a bladder infection may travel into your kidneys, causing a severe and potentially life-threatening infection called pyelonephritis. If you believe you have a bladder infection, seek care from your medical provider to ensure you receive appropriate treatment.
Recommended Dosage
Taking 400 mg of powdered cranberry concentrate two times each day may help prevent bladder infections. Alternatively, you can drink 4 to 10 oz of cranberry juice each day to help protect your bladder against infection.
Safety Issues
Treatment with cranberries may cause mild stomach irritation or diarrhea in certain people. If you have a personal history of kidney stones, consult your doctor before taking cranberry tablets. Cranberries contain a high level of oxalates, a substance associated with an increased risk of kidney stones. As noted previously, cranberry tablets should not be used in place of antibiotics if you have an active urinary tract infection.
Medication Interactions
If you're taking certain medications, treatment with cranberry tablets may be inappropriate. Avoid using cranberry tablets in conjunction with blood-thinning medications, such as warfarin. Cranberries may enhance the effects of blood thinners, which may increase your risk of bruising or bleeding.
