Prescribing Adaptations

Warfarin was switched to DOACs or NOACs for visually impaired patients because warfarin's colour-coded, variable-dose tablets are hazardous for this group. Insulin pens were highlighted as a serious and under-recognised risk, with one patient experiencing recurrent hypoglycaemia because she could not read the dose indicator. Liquid medications were identified as particularly hazardous for OPwSI because accurate measurement requires visual acuity many patients lack. Simplifying treatment regimens with once-daily dosing was the most consistently reported prescribing modification for OPwSI. Preloaded injectables were preferred over self-draw injectables for visually impaired patients because they eliminate the need to measure and draw up doses. Inhalers with auditory or tactile confirmation, such as a Symbicort inhaler producing a distinct click, were preferred over devices requiring visual inspection.
