how long does letrozole stay in your system
My RE typically only prescribes Letrozole for a few different reasons: 1) Clomid stays in your system for 5-7 days where Femara (Letrozole) stays in your system for 2 days. 2) Because Clomid stays in your system longer, it can affect the development of a baby and cause birth defects. 3) Femara doesn't reduce your estrogen levels as much so no need to take an estrogen supplement.
