What is Cystopurin?

Cystopurin is a pharmacy medicine used to relieve the uncomfortable and painful symptoms associated with cystitis and lower urinary tract irritation. Cystitis is commonly caused by a bacterial infection of the bladder and is particularly common in women, although it can affect men and adolescents as well. The discomfort experienced during cystitis is partly due to acidic urine, which irritates the inflamed lining of the bladder and urethra. This irritation leads to symptoms such as burning during urination, frequent urges to pass urine, and lower abdominal discomfort. Cystopurin contains potassium citrate, a urinary alkalinising agent. When dissolved in water and taken orally, it increases the pH of the urine, making it less acidic. This helps soothe the urinary tract, reducing pain and discomfort while urinating. Cystopurin does not kill bacteria or cure the infection itself. If symptoms persist, worsen, or recur frequently, medical assessment is required, as antibiotics or further investigations may be needed.

How Cystopurin Works

Urine is naturally acidic, but during cystitis the acidity can increase and intensify irritation of the bladder lining. This leads to the classic symptoms of cystitis:
  • Burning or stinging pain when passing urine
  • Frequent need to urinate, even when little urine is passed
  • Urgency to urinate
  • Lower abdominal pressure or discomfort
Potassium citrate works by neutralising excess acidity in the urine. By increasing urinary pH, it reduces chemical irritation of the inflamed tissues, allowing the bladder lining to feel calmer and less painful. This mechanism makes Cystopurin particularly useful for symptom relief in mild or early cystitis and as a supportive treatment alongside antibiotics when prescribed.

Cystopurin can be used as a supportive treatment alongside antibiotics if recommended by a healthcare professional.

These measures may help reduce symptom severity and recurrence.
