A small section of the drug labels available on the Pharmacogenomics Knowledgebase (PharmGKB). PharmGKB tags Food and Drug Administration (FDA) labels with a B inside a blue square if the label came from the FDA's Biomarker list (https://www.fda.gov/drugs/scienceresearch/researchareas/pharmacogenetics/ucm083378.htm). A small set of labels contain specific dosing guidance based on genetic information; these labels are tagged as including dosing information. For example, in the above image, aripiprazole is tagged in this manner because the FDA label states that CYP2D6 poor metabolizers should have their dose reduced by 50%
