Moderate Interactions (Monitor Closely): - Antifungals (e.g., ketoconazole): may increase hormone concentrations. - Antibiotics (e.g., tetracycline): possible reduced efficacy. - SSRIs (e.g., fluoxetine): may affect hormone metabolism. - Diuretics (e.g., hydrochlorothiazide): monitor blood pressure changes.
