Metformin 

Metformin is a medicine used to treat patients with type 2 diabetes and sometimes in women with polycstic ovary syndrome. It may also be referred to by its brand names Bolamyn®, Diagemet®, Glucient®, Glucophage® or Metabet®. 

Although metformin is used to reduce blood glucose levels in patients with diabetes, it does not lower glucose levels in the brain.

NICE do not recommend metformin as a treatment for brain tumours. It is important to speak to your healthcare team before taking any new medications or making changes to your current brain tumour treatment.
