Eight serious shortage protocols (SSPs) for phenoxymethylpenicillin V (Pen V) that were due to expire yesterday have been extended until the end of February.

Two antibiotics, azithromycin and clarithromycin, have also been removed from the list of medicines that can be supplied as an alternative under five of the Pen V SSPs.

Instead, only amoxicillin, flucloxacillin, cefalexin or co-amoxiclav can be supplied as an alternative to phenoxymethylpenicillin 250mg tablets, 250mg/5ml oral solution and 250mg/5ml oral solution sugar free, as well as 125mg/5ml oral solution and 125mg/5ml oral solution sugar free, under SSP043 – SSP047. The alternatives should be supplied in that order of priority.
