Department of Health and Social Care (DHSC) has issued a medicine supply notification for ketotifen 1mg/5ml elixir (Zaditen)

• Zaditen® 1mg/5ml elixir is currently out of stock with no confirmed resupply date.
• Zaditen® 1mg tablets are available and can support demand of the elixir if deemed appropriate. (Zaditen® 1mg tablets and 1mg/5ml elixir were discontinued in 2019, however, in June 2020 both preparations were re-introduced back to the UK market.)
• Unlicensed imports of ketotifen elixir have been sourced; lead times vary.

The following specialist importers have confirmed they can source unlicensed ketotifen 1mg/5ml elixir (please note, there may be other companies that can also source supplies):

There is currently no listing on dm+d for the imported product for prescribers to select using their prescribing systems so an EPS prescription for unlicensed ketotifen 1mg/5ml elixir  cannot be issued. Where a prescriber wishes to prescribe an unlicensed import, an FP10 paper prescription should be issued as 'Ketotifen 1mg/5ml elixir (Special Order)' and endorsed by the pharmacy as a non-Part VIIIB special with the following information:

  • Amount dispensed over pack size used;
  • Invoice price per pack size from which the order was supplied lessany discount or rebate;
  • Manufacturers'/importers' MHRA licence number;
  • Batch number of the product supplied;
