Most Neo-Sensitabs are stable at room temperature for a number of years, a few of the more labile antibiotics should be refrigerated for long term storage. However even the more labile antibiotics are stable at room temperature for 2 months which means in most cases working stock will not need refrigeration on a daily basis as is the case with paper discs.
Why are most Neo-Sensitabs stable at room temperature?
Unlike paper discs we use the dry crystalline antimicrobial which is compacted into tablets.
Does stability mean better results?
A multi centre evaluation in UK hospitals showed good comparison between paper discs and Rosco tablets with 'stable' antibiotics but significantly better results obtained with Rosco tablets when the antibiotic was less stable (co-amoxyclav).
