For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.

Summary

Rifampin induces CYP3A4 and reduces saxagliptin exposure, although the active metabolite increases, so overall DPP-4 inhibition is largely maintained. The clinical impact on glycemic control is generally small.

What this interaction means in plain words

Rifampin and Saxagliptin have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.

Evidence level: Moderate

Why it happens

Rifampin induction of CYP3A4/5 increases saxagliptin metabolism, with partly offsetting formation of the active metabolite.

What to do

No dose adjustment is usually required; monitor glucose control when rifampin is started or stopped.
