Summary
Strong CYP3A4 inducers markedly reduce flibanserin exposure, but dexamethasone is only a weak-to-moderate inducer and topical exposure is minimal. Any loss of efficacy would be limited to prolonged systemic use.
What this interaction means in plain words
Dexamethasone-tobramycin and Flibanserin have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Dexamethasone-tobramycin belongs to Anti Bacterial; Flibanserin belongs to Genitourinary.
Why it happens
Possible CYP3A4 induction by dexamethasone increases flibanserin metabolism.
What to do
