To ask the Secretary of State for Health and Social Care, what assessment his Department has made of the potential impact of levels of epilepsy medication availability on patient safety.

Medicine supply issues are global in their nature and, whilst not wholly preventable, the Department has a range of well-established processes and tools to manage and mitigate risks to patients. The Department has worked hard with industry to help resolve intermittent supply issues with some epilepsy medications. As a result of ongoing activity and intensive work, including asking manufacturers to expedite deliveries, most issues have been resolved.

The Department is currently aware of supply issues affecting some suppliers of clobazam 10 milligram tablets, all strengths of topiramate tablets, clonazepam 2 milligram tablets, and phenobarbital 15 milligram tablets, used in the management of epilepsy.

The supply issue with clonazepam 2mg tablets from one manufacturer is expected to resolve late January 2026. The affected suppliers of topiramate 25 milligram and 50 milligram tablets, and clobazam 10 milligram tablets, are expected to resupply these products by early December 2025. The resupply date from the other affected manufacturers for topiramate 50 milligram, 100 milligram and 200 milligram tablets and phenobarbital 15 milligram tablets is yet to be confirmed. Stock remains available from alternative manufacturers of these products to meet patient demand, and we have issued comprehensive management guidance to the National Health Service.

We have issued guidance for the discontinuation of sodium valproate (Epilim Chronosphere) 750 milligram and 1000 milligram modified release (MR) granules sachets. Alternative strengths of sodium valproate MR granules sachets remain available.
