Urologists soothe irritated bladder linings with bladder instillations, a treatment where liquid medication is placed directly into the bladder through a thin catheter so it coats the damaged lining rather than traveling through the bloodstream. Common wash ingredients include dimethyl sulfoxide (DMSO), heparin, lidocaine, sodium bicarbonate, and hyaluronic acid or chondroitin sulfate, often combined into a "rescue cocktail" that reduces inflammation and helps rebuild the bladder's protective GAG layer. The solution is typically held in the bladder for 15 to 30 minutes before being released, with treatment usually given weekly for six to eight weeks and then tapered based on response. Relief varies widely: some people notice calmer urgency and less pelvic pain after the first few sessions, while others need several rounds or a different medication mix, and mild stinging or temporary flare-ups can occur afterward. There are several factors to consider, including your specific diagnosis, prior treatments, and how your bladder responds. See below to understand more.

Because bladder pain, urgency, and burning can stem from interstitial cystitis, infection, pelvic floor dysfunction, or other conditions that call for very different treatments, understanding what is driving your symptoms matters before starting any therapy. A free, instant, online symptom check can help you organize what you are feeling, see which conditions match your pattern, and walk into your urology appointment with clearer questions and a faster path to the right next step.Urologists soothe irritated bladder linings with bladder instillations, a treatment where liquid medication is placed directly into the bladder through a thin catheter so it coats the damaged lining instead of traveling through the bloodstream.

Irritated bladder linings can lead to painful, frequent urination and significant impact on daily life. For people with interstitial cystitis or those with fibromyalgia who also experience bladder pain, targeted bladder instillations offer an effective, localized approach. This article explains how urologists perform these “medication washes,” what to expect, and how they can help soothe the bladder lining without masking symptoms or causing undue anxiety.
Oral medications for IC and bladder pain can have systemic side effects and may not deliver enough active drug directly to the bladder wall. Bladder instillations:
Urologists may use one or a combination of these solutions, depending on individual needs:
Most people undergo instillations once or twice a week for 4–6 weeks, followed by a maintenance schedule as recommended by their urologist.
While generally safe, bladder instillations can cause:
Discuss any concerns with your urologist. They’ll tailor treatments to minimize irritation and monitor for adverse events.
If symptoms improve, your urologist may extend the interval between instillations or switch to maintenance doses. If relief is limited, they might:
Persistent or worsening symptoms, new blood in urine, high fever, or intense pain warrant prompt evaluation. Don’t hesitate to:
Bladder instillations can be a powerful tool for people with interstitial cystitis, especially those managing bladder pain alongside fibromyalgia. If you’re considering this treatment or have any symptoms that could be serious, speak to a doctor right away. A medical professional can confirm your diagnosis, discuss risks, and help create a personalized care plan that addresses both comfort and safety.
