Letrozole side effects and timing?

@teacher22 thanks for your insight. How often does your oncologist check your liver? While I have had blood work done since I started letrozole in April it hasn’t been ordered by my oncologist.

@wews :
Just to offer my 2cents based on my personal experience...
My medical oncologist ordered quarterly COMPREHENSIVE METABOLIC PANEL and CBC W/ AUTO DIFFERENTIAL blood work done for me to make sure that all the elements are in normal range ever since I started taking Anarzole 2 years ago. COMPREHENSIVE METABOLIC PANEL checks including key liver enzymes such as: ALT, AST, measured in blood tests.
Best wishes to you all on the journey ahead and Happy New Year!
@wews My levels were checked by Primary Doctor during a yearly physical. In September of 2025 my blood work (done by Cancer center) were in the normal range they were significantly elevated in December 2025. I switched from Anastrozole (due to emotional side effects) to Letrozole in late November. I have a CT scheduled for tomorrow.

I was referred to a hepatologist. When I had high liver enzymes I was getting them checked every two weeks. Then it was once a month and then three months. Because they have been at normal levels or only slightly elevated, I just get them checked when my hematologist does a complete metabolic panel around every six months.
