Older adults warn that changing pill colors and shapes cause dangerous confusion

Barbara Wolf, a 73‑year‑old from Birmingham, Alabama, takes six medications each day and relies on the color, shape and size of each pill to keep her regimen straight.

She recently received a refill in which a familiar blue tablet had turned yellow, and recalls earlier changes from white‑blue to white‑purple and from pink to blue. Each alteration startled her and forced her to double‑check with the pharmacist before taking the medicine.

Wolf argues that pharmaceutical companies, generic manufacturers and pharmacists should limit cosmetic changes to pills. Alterations can create confusion, increase the risk of taking the wrong drug or missing a dose, and potentially lead to serious health consequences.

While pill organizers help many patients manage their regimens, Wolf says that visual changes still pose a real safety concern for older adults who depend on appearance cues.
