Dad had a problem tonight; he was adding my liquid meds and forgot which ones had already been added. He was able to figure it out, but it worried him that I might get too much or not enough of a med if he couldn't figure it out. One of the meds is bluish and the other two are white and he wondered if each med could be made a different color to help distinguish between them. He's going to ask the pharmacist the next time we need refills.
