Does Grapefruit Extract Affect Propecia?

hello dr

i want to ask you about this fat burner as it has grapefruit extract. does this product accelerate hair loss or affect propecia effects?

Grapefruit is problematic with many medications due to the way it metabolizes, and I’d expect grapefruit extract would be similar. In simple terms grapefruit can compete with the metabolism of many drugs including Propecia so you may end up with higher levels of Propecia in your blood stream. This is not necessarily good. If possible I would NOT take grapefruit and Propecia at the same time.
