Over here, it lists drugs that will affect Avodart:

and here, it states: "Ketoconazole may increase the blood levels of dutasteride"

So, using keto will actually increase the effectiveness of dutasteride?

Upon further reading, dutasteride is metabolized extensively by CYP3A4 enzyme, whereas Ketoconazole is a strong CYP3A4 inhibitor, and they do have drug interaction.

So, better avoid using ketoconazole while on dut?
