Trick of the Trade
Ask about the color of his/her warfarin tablets
In the United States, manufacturers of both brand and generic warfarin have agreed to make each strength a consistent color. While the colors do NOT change, the shape and shade may vary.
To aid your memory recall of the colors, you can use this mnemonic
“Please Let Granny Brown Bring Peaches To Your Wedding”
Alternatively, @scepticalemdoc from Queensland, Australia offered an EM-related mnemonic:
“Probably Leaves Granny Bleeding Bloody Profusely, Thank You Warfarin”
|Mnemonic||Warfarin Tablet Color||Tablet Strength|
While this color-coding scheme holds true for warfarin dispensed in the United States, it may not apply in other countries. Also be cautious of patients with deuteranopia (color-blindness), who may mistakenly report the wrong tablet color.
