Update on ophthalmic medicine shortages April 2023

There are currently UK-wide shortages of some eye medications.

Our pharmacy team is receiving an increased number of calls and emails from patients as a result of these shortages, which we are unable to respond to. We are communicating with patients via our website, advising them to ask their local pharmacy about alternative options.Please direct patients to their local pharmacy and not to Moorfields.
The following table lists affected stock, timescales for resolution, and suggests temporary alternatives.

Please note, if the medication is not listed in the table – there is not a shortage.

Please be aware that at present there are very limited/no UK supplies of pilocarpine 4% eye drops, Diamox SR® 250mg Prolonged-release Capsules, Verkazia and Ikervis – please see details below of the alternatives used at Moorfields:
