Rimso-50 is indicated for the symptomatic relief of interstitial cystitis, also known as painful bladder syndrome. This condition is characterized by chronic bladder pain, urinary urgency, and frequency.
Dimethyl sulfoxide (DMSO) is thought to work through multiple mechanisms including anti-inflammatory effects, muscle relaxation, and possibly by reducing pain sensation. When instilled directly into the bladder, it contacts the inflamed bladder wall directly.
Rimso-50 is administered via catheter directly into the bladder by a healthcare provider, typically on a weekly basis for a prescribed number of treatments. Patients may experience a garlic-like taste or body odor during treatment. Full benefit may take several weeks of therapy to achieve.
