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 change in your medication will be given to you when you collect your next repeat prescription.

WHAT YOU TAKE NOW: Metformin 1g tablet

WHAT IT WILL CHANGE TO: TWO metformin 500mg tablets

The new medication is the same as your old medication. However, you will be taking two tablets instead of one tablet of the new medicine at the same time/s as before. Please finish taking all the metformin 1g tablets you currently have before starting on the new medicine. The new metformin 500mg tablets will look smaller than the old metformin 1g tablets because each tablet contains half the amount of medicine when compared to your old medication. Hence the appearance of the new tablets may differ from your previous product, however apart from this you should notice no difference at all.

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 or your local community pharmacist.

Yours sincerely
