Interstitial cystitis is an inflammation of the bladder that is not caused by an infection. Symptoms of interstitial cystitis include pain, increased need to urinate and incontinence. Conventional approach includes dietary changes, bladder training, medication and surgery. Although many individuals show improvement while following conventional treatment, most cases are not completely cured, says Merck Manual. Quercetin is a natural supplement that has shown potential benefits in managing interstitial cystitis, especially when combined with other natural supplements. If you suffer from interstitial cystitis and are considering taking quercetin, you should first talk to your doctor.
About Quercetin
Quercetin is a natural substance found in citrus fruits, apples, berries, parsley, tea and red wine. Quercetin is also available as an over-the-counter supplement. This nutrient possesses antioxidant and anti-inflammatory qualities, and belongs to a class of plant substances called bioflavonoids.
Research
A standardized supplement that includes quercetin was found beneficial in managing interstitial cystitis, according to a study published in the December 2008 issue of "The Canadian Journal of Urology." This study involved 252 participants diagnosed with interstitial cystitis and painful bladder syndrome who did not respond to conventional therapy. The herbal combination used during the study contained quercetin and its related compound rutin, as well as chondroitin, glucosamine and hyaluronate. The researchers from Tufts Medical Center in Boston concluded that this herbal combination may be useful in managing cases of interstitial cystitis, particularly those cases that fail to respond to conventional therapy. The University of Maryland Medical Center also notes two research studies that showed that quercetin may be beneficial for individuals with interstitial cystitis; however, more research is needed to fully confirm these findings.
Dosage
Quercetin is not safe for children. For adults suffering from interstitial cystitis, a daily dose of 500 mg of quercetin is recommended, according to the University of Maryland Medical Center.
Side Effects and Drug Interactions
Quercetin is generally considered a safe and well tolerated supplement. In rare cases, it may cause stomach upset and headaches. Do not take more than 1 g a day of quercetin, as it may cause kidney complications, warns UMMC. Quercetin may interact with some conventional drugs including blood thinners, chemotherapy drugs and steroid medication.
Considerations
Consult a doctor to find out if you may benefit from taking quercetin for your condition. Keep in mind that quercetin does not replace and should not be used to replace any conventional therapy for interstitial cystitis. Quercetin is not approved by U.S. Food and Drug Administration to treat this condition.
