We have made no estimate. The joint NHS England and NHS Clinical Commissioners guidance ‘Conditions for which over the counter items should not routinely be prescribed in primary care: guidance for CCGs’ was published in 2018. It recommends that over the counter items should not be prescribed for 35 conditions that are either minor or will resolve without treatment, and that probiotics and vitamins and minerals, which are not clinically effective, should also not be prescribed.
The guidance is currently being updated and is expected to be published this spring. This will include estimates of potential financial savings for the National Health Service of not prescribing over-the-counter items, taking account of the changes in prescribing volumes since publication of the guidance.
