How to calculate the amount of insulin to prescribe per month

Over-prescribing repeat medication may ensure that a person does not run out of a vital medication, but there are cost implications for the NHS. It may also be difficult for the person to store larger quantities (particularly where a medication should be stored in a fridge). There is a risk of older medication expiring before it has been used and being thrown away or, potentially, used after the expiry date when it may not be safe or effective to do so. This guide is designed to help prescribers calculate how much insulin to prescribe each month for people on stable doses of insulin.
