Summary
Antibiotics have been theorised to lower estrogen levels by disrupting gut bacteria that help recycle estrogens. For an oral menopausal hormone product the clinical impact is unlikely to be meaningful, and the evidence for tigecycline specifically is weak.
What this interaction means in plain words
Bazedoxifene / conjugated estrogens and Tigecycline have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Theoretical reduction in enterohepatic recirculation of estrogens through altered intestinal flora.
What to do
No routine change is needed. Review the patient if menopausal symptoms or unexpected bleeding appear during prolonged antibiotic therapy.
