Discontinued and Outdated Treatments

The AUA Guidelines specifically discourage the use of several therapies due to poor results and/or the risk of adverse events. In addition, several older, out-dated therapies were not discussed and/or recommended.

Long Term Antibiotic Therapy

Research studies have not found significant improvement in IC symptoms when treated with long term-antibiotics.(1) Adverse events, on the otherhand, were profound including GI disturbances, vaginal infections, nausea and dizziness (2)(3). The risk of fostering antibiotic resistant infections must also be considered. As a result, the AUA panel judged that antibiotic treatment is contraindicated in the treatment of IC in patients who have a negative urine culture and who have been treated previously. They do NOT, however, want to discourage the use of antibiotics in patients using prophylactic antibiotics to treat recurrent bladder infection.

Bacillus Calmette Guerin (BCG)

Bacillus Calmette Guerin is a therapy used for the treatment of bladder cancer. Four studies found BCG to be no more effective than placebo for the treatment of IC thus the AUA now specifically discourages its use other than in a research setting.(3,4,5,6) Side effects can be severe, including fatality.(7)

Resiniferatoxin (RTX)

Resiniferatoxin is another investigational medication that had little success with studies showing no difference from placebo.(8) Patients also reported severe pain after treatment. As a result, the AUA does not recommend this therapy.

High Pressure, Long Duration Hydrodistention

High -pressure (e.g., greater than 80 to 100 cm H20), long-duration (e.g., greater than 10 min) hydrodistension is associated with increased frequency of serious adverse events (e.g., bladder rupture, sepsis) without a consistent increase in benefit.(9-10) As a result, the AUA strongly discourages their use.

Long-term Glucocorticoid therapy

Two studies found marginal success and serious adverse events when glucocorticoids were used as a long-term therapy for IC.(11,12) Of particular concern were reports severe side effects including: new diabetes onset, exacerbation of diabetes, pneumonia with septic shock and increased blood pressure. The AUA believes that the risks of this treatment clearly outweigh any potential benefit. Short term use may be considered for flares, however.

Silver Nitrate, Clorpactin & Agyrol

Not even mentioned in the AUA Guidelines is the use of Silver Nitrate and Clorpactin, commonly used from the 1950′s through the 1990′s. Patients may occasionally encounter physicians who use them today however the AUA does not suggest nor recommended them. They have been replaced with the far more effective bladder instillations, such as a rescue instillation. A key concern for both silver nitrate and clorpactin is their caustic effect. Both can cause severe damage to the bladder wall and underlying nerves.

Argyrol (“mild silver protein solution”) was used, at one point, as a bladder instillation. Less caustic that silver nitrate, it was believed to provide an antiseptic effect to the bladder wall. There is no evidence showing any effect in the treatment of IC.
