Letrozole side effects and timing?

Posted by wews @wews, 1 day ago

Could those of you you are taking or have taken letrozole share when side effects started to appear? I have been taking it since April 2025 and within the last month I am losing hair, feel some stomach and intestine discomfort and some joint and low back pain. I work out and do yoga and breathing which helps the joint and back but has anyone else noticed their hair falling out or thinning? Also do these side effects go away after a bit or do they get worse over time? What are your experiences? I have to stay on this for a long time and would love to prepare myself. Thanks.

Hair loss was my most significant and bothersome side effect. I was switched to exemestane but hair loss continued. I saw a dermatologist.

When did you hair loss start and how long did it go on? What did the dermatologist do to stop it? I am so upset. My oncologist also said all the drugs to block estrogen have this potential side effect. Were you able to grow hair back with your doctors help or stop it from falling out?
