Summary
Antibiotics were once thought to lower oral estrogen levels by disrupting gut flora and enterohepatic recycling. Evidence for non-rifamycin antibiotics such as ofloxacin shows no meaningful loss of hormonal effect, and clinically important failure is unlikely.
What this interaction means in plain words
Estradiol and Ofloxacin have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Estradiol belongs to Endocrine; Ofloxacin belongs to Anti Bacterial.
Why it happens
Theoretical reduction in enterohepatic recirculation of estrogen from altered gut flora; not shown to be clinically significant.
What to do
No change in estrogen therapy is generally needed. Advise additional contraception only if vomiting or severe diarrhea occurs.
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?
