Phosphate enema (Cleen)


Sample letter advising patients of a switch


Dear Patient


The NHS carries out regular reviews of medicines to make sure that patients continue to receive high quality and effective treatment that costs the NHS less.


The latest review involves a change in one of the medications on your prescription. The full details of the change are shown below and this new medication will be given to you when you collect your next repeat prescription.


              Phosphate enema Formula B standard tube will change to Cleen® ready-to-use enema


              Phosphate enema Formula B long tube will change to Cleen® ready-to-use enema


This new medicine contains the same active ingredient as your old medication so please continue to use it in the same way and at the same dose as before Please use all the Phosphate enemas Formula B you currently have before starting on the Cleen® ready-to-use enemas. The appearance of the new version of enema will be different from your previous product, however you should notice no difference in how it works as it is equally effective and has the same side effects as your old version.


To obtain your next supply of medicines more efficiently, you can order a repeat prescription by logging into your account using the NHS app which may be downloaded from the NHS website.  We would also like to take this opportunity to remind you to only order the medicines you need each time you resubmit your repeat prescription request as this helps minimise medicine waste.   


If you are concerned or wish to discuss the matter further, please do not hesitate to contact the practice.


Yours sincerely
