Summary
Oral erythromycin may alter gut flora, which in theory could reduce the bacterial contribution to biotin availability. Dietary and supplemental biotin is the main source, so a clinically meaningful drop in biotin status is not expected.
What this interaction means in plain words
Biotin and Erythromycin base 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
Antibiotic-related change in intestinal bacteria that synthesize some biotin; the effect is theoretical.
What to do
No routine action is needed. Consider checking biotin status only if deficiency symptoms occur during prolonged antibiotic courses.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
