CYP2B6 is a gene. This site has 0 published variants inside it and 1 near it, each from a published genetic study, joining it to 2 drug pages.
CPIC, the international group that writes gene-based prescribing guidelines, rates how strong the evidence is for each gene and medicine, from A (strong enough to change the prescription) to D (weak or conflicting). Every rating is shown, the weak ones included, so you can see where the evidence stops.

The FDA keeps a list of medicine labels that mention a gene. These are the ones that name CYP2B6. Where this site has a page on the medicine, the name links to it; otherwise it opens the label on DailyMed. A label naming a gene does not always mean a test or a dose change: for many it is one line about how the body clears the drug.

Positions outside the gene, filed under it because it is the closest. A variant near a gene does not always act through it.

A gene page gathers published research; it is not a test result and not medical advice. If a gene matters to your health, talk to a doctor or a genetic counsellor.
