Any help here would be welcome ty

  • A very warm welcome to the forum Alfiesme although I'm sorry to hear what has happened since you starting taking Letrozole.

    Whilst side effects can vary from person to person, if what you're currently experiencing is making you feel really unwell then don't hesitate to let your medical team and/or GP know.

    Hopefully some of our members who are taking Letrozole will share their experiences and advice with you soon but if it would help to have a chat about this with one of our cancer nurses, they're available Monday - Friday between 9a.m - 5p.m on 0808 800 4040. They're very well informed and with their knowledge and insight they will do all they can to support you and address your concerns.

    In the meantime, we're sending you all our support Alfiesme and will have our fingers crossed things start to get better soon.

    Kind regards,

    Steph, Cancer Chat Moderator
