Hi everyone - living with side effects of letrozole

I was diagnosed with breast cancer at the end of 2023. I had a lumpectomy and so far I’m still clear. They put me on Letrozole straight away and, apart from some night sweats, muscle aches and headaches, it’s been ok so far. I’m now getting a completely different symptom. I’ve had brain fog, mainly losing words when talking, for a couple of months and didn’t know until recently that apparently Letrozole can cause this.

I look forward to talking to everyone on here.

  • Hello Crystal53

    I'm sorry to hear that you've recently had some new symptoms appear, which you feel are attributed to letrozole. One of the side effects listed for Letrozole is problems with your memory. 

    It's worth talking things through with your specialist cancer nurse or GP if you feel that the side effects are impacting your daily life. Some women report that they find side effects can change when using different brands of medication, so if you've recently changed brand of letrozole, then it's worth talking with your pharmacist about trying a different brand to see if this helps. 

    If you'd like to chat things through with one of our nurses, you're welcome to call them on 0808 800 4040, Monday to Friday, 9am to 5pm. I know they will be happy to listen and offer any advice, information and support they can. 

    I hope things settle for you soon Crystal53. Keep in touch and let us know how you get on. 

    Best wishes,
