Cleen Ready to Use Enema - 133ml

What Is a Phosphate Enema and How Does Cleen Work?

Constipation can be genuinely uncomfortable — and sometimes, oral laxatives simply do not act quickly enough. The phosphate enema has been used for decades as a reliable, fast-acting rectal solution for bowel evacuation. Cleen Ready to Use Enema 133ml contains sodium acid phosphate and sodium phosphate as its active ingredients, delivered in a pre-filled, single-use squeeze bottle that makes administration as straightforward as possible. If you are looking for effective relief from constipation or need to clear the bowel before a medical procedure, this product is worth understanding properly. You can also explore our wider range of constipation treatments if you want to compare options before deciding.

Cleen is a well-established brand in the UK, and this 133ml ready-to-use format means there is no mixing or measuring involved. The solution is administered rectally, and results are typically seen within 2 to 5 minutes. That speed of action is one of the main reasons healthcare professionals and patients alike reach for this product when prompt bowel clearance is needed.

How Does Cleen Ready to Use Enema Work in the Body?

The mechanism is based on osmosis. When the sodium phosphate solution is introduced into the rectum, it draws water from surrounding tissues into the bowel lumen. This increase in fluid volume softens the stool and distends the rectal wall, triggering the urge to defecate. It is a local action — the solution is not intended to be absorbed systemically in significant amounts at the recommended dose.

• Sodium phosphate creates an osmotic gradient in the rectum
• Water is drawn into the bowel, softening impacted stool
• Rectal distension stimulates peristaltic contractions
• Bowel movement typically occurs within 2–5 minutes

How Does Cleen Enema Compare to Other Constipation Treatments?

Is Cleen Ready to Use Enema Suitable for Long-Term Use?

This product is intended for short-term or occasional use only. Regular reliance on any enema — including a phosphate enema — can disrupt the natural balance of electrolytes in the body and may reduce the bowel's natural motility over time. If you find yourself needing to use it frequently, that is a signal to speak with your GP about the underlying cause of your constipation. Chronic constipation often has dietary, lifestyle, or medical causes that deserve proper investigation rather than repeated symptomatic treatment.

Store the product below 25°C and keep it out of reach of children. Do not refrigerate. Check the expiry date before use and do not use if the seal is broken.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.
