Letrozole

Hi I’m new to this forum.  I have had breast cancer twice, 2nd time round was in the same breast.  Because of this I decided to go for a double mastectomy to avoid a “3rd” time.  First time round I was put into Tamoxifen for 5 years, apart from the common side effect of hot flushes & mega weight gain  I felt well on then.  However, I’m now on Letrozole, have been taking them for just over 12 months and am experiencing just about every single side effect listed and more.  Recently I have been getting excessive sweating, dull like growing pain in my left leg from hip to  knee, excessive fatigue and more recently bouts of Vertigo & Tinnitus which are so debilitating I keep having to take time off work.  I’m interested to find out  if anyone else is experiencing this on Letrozole?  I also have aching joints which I can cope with, excessive itchiness all over the body, mainly at nigh but I take antihistamines for that.

With all of this going on it’s making me feel like a complete hypercondriact... is anyone else experiencing all of this and how do you cope? 

I look forwards to your comments xx

  • Hi, if you type letrozole side effects into the search option you will find thousands of comments. I am two years post bc and having almost every side effect listed, I stopped taking it a month ago and have seen some improvements, I see my consultant in January and will discuss it then but I really don’t think I will take it again. I can’t cope anymore with the pains and bone aches and I have already tried Anastrozole with similar problems. At the moment I am all about quality of life, but that is my choice. You are not alone with your problems, people on here do understand. I researched my problems before realising it was side effects, not the other way round, and made my decision to stop taking Letrozole. No doubt the consultant will come up with something else but in the meantime I am seeing what the difference is . Hope this helps. Sue
  • I had breast cancer removed Aug 2013.  Started on Letrozole April 2014 for a year but because of aches & pains I got moved onto Anastrozole.  At first I thought it was better, but been on it now for over 2 years & I'm crippled with joint pain, shoulders, hips, knees, particularly left leg, foot deformed, bakers cyst behind left knee.  I'd asked consultant if I could stop it.  He said no & offered Tamoxifen, I said no.  2 weeks ago I went to GP who offered me a break for a month to see if there was improvement.  So I've stopped taking it.  I value quality of life.  My bakers cyst has reduced & hot flushes have stopped!  I've been cold.  Haven't been cold in over 3 years. In 2 years by bone density has gone from above average to osteopenia of the spine.  I know someone who has been on it for 6 years without any side effects.  It must affect people who are prone to arthritis.  My cancer was the most oestrogen positive you could get, but a risk I'm prepared to take rather than suffering.  Also had the insomnia & itching, take antihystamines to control it & constipation.  But prone to the latter two anyway.

  • Hello Jolamine...

    Thank you for your reply, please don't be sorry, nice of you to ask...

    The eye thing is like a physical feeling of something being caught on something... really weird....I feel like if I could put scissors under my eyeball and snip it would go.... it's like when I look up the lower part of my eye is attached to something it shouldn't be... that's the best I can do for explaining...

    The Dr today said he could only tell me if my eyes are good or bad... not necessarily what is causing another problem. He said I do not need to see an optician for two years.... there is nothing wrong ... this is just frustrating....but because of the MRI scan I do kind of feel better. 

    Don't know where to turn with it so just gonna leave it for now. Maybe I've reached a point where this is as good as it gets... weird vision, painful left hip and left knee... general joint arthralgia... still too scared to stop the Letrozole....so I think I'll just shut up moaning and plod on.....from the things I've read I really could be in a worse situation with my prognosis.

    How are you??

    Hi MilosMum,

    I am a lot better now that I am no longer taking Letrozole, although I still suffer with some of the side-effects. Still, I'm glad that I perservered with it, because I feel that I have done all that I can to keep the cancer at bay.

    Like you, I feel that I could be a lot worse off and, I'm grateful to still be here 12years after my first diagnosis.

    Kind regards,

  • Hello,

     

    I have been on Letrozole for two years and have the same joint pains and aches as so many people report.  I am thinking of taking a Letrozole,holiday around my son's wedding.  I'd be interested to hear from anyone who has taken a holiday and to know how long for and how long before symptoms improved...if they did.

  • Hi, 

    I posted in April 2017 about this , it may help you. Briefly at the end of my tether I just stopped and within a a week I felt so much better. A locum consultant just left it at that, but 5 months later a new consultant put me on Aromasin, also called Exemestane and the side effects are nothing like as bad. I still take it so that says something. I think it was quite new then. 

    you don't have to suffer in silence, ask for a change and push for it. We are all different and affected in different ways so a different medication may well suit you better. I have had 4 different meds and letrozole was by far the worst, I am hoping to stop altogether next year. 
    good luck, enjoy the wedding.

    Hi Shermalt,

    A very warm welcome to our forum.

    I am sorry to hear about the trouble you've had with Letrozole. I took Tamoxifen for 1 year, then Letrozole for 6½ years. I had a number of side-effects. I stopped taking these in July 2017, but my joint pains have never subsided since.

    Have you discussed taking a break with your consultant or nurse? It is always worth doing this first. The other thing you could do is to follow Snowdrops' advice and change to aother drug with fewer side-effects. I hope that you still have time to get this sorted before your son's wedding and that you all have a wonderful day.

    Please keep in touch and let us know how you get on. We are always here for you.

    Kind regards,

  • Hello Snowdrops and Jolamine,

     

    Thank you both for your replies.  It really does help to share experiences.  I have been in touch with my oncologist and will see what he says.  I have slight osteoporosis now and am really keen to keep that in check so want to do something about Letrozole.  I take a lot of exercise and do specific ones set by the a physio friend every day but I don't think it is making much difference, to be honest.  I wake up very stiff in the mornings and have to work hard to get everything moving!

  • Hi Shermalt.

    I also take Adcal on prescription. It's a calcium and vitamin D supplement and was prescribed as soon as chemotherapy and radiotherapy treatment ended. This could help with osteoporosis.

    good luck. 

  • What side affects do you get when coming off Letrozole?.  I have been told it is time to stop taking it.   Quite truthfully, it scares me in case the cancer comes back.   Arianna.

  • Hello Shermelt,

    Your symptoms might be something else entirely.  Obviously I don't know what age you are, but probably need to be checked for any form of arthritis etc.   I actually have similar symptoms to what you describe, and I have fibromyalgia, which is a chronic condition and causes pain in the muscles and stiffness in the morning and after resting etc.  There is a lot more to it.   It would be a good idea to consult a doctor and will possibly be referred to a rheumatologist, for a blood test etc.

    Hi Arianne,

    A very warm welcom to our forum.

    I took Tamoxifen for one year, following a lumpectomy. The following year I found a lump in the same breast and had a double mastectomy. Following this, I took Letrozole for six and a half years. I stopped taking this in July 2017. Once we have had cancer, we all have to learn to live with the fear of recurrence. I can honestly say that although I had several side-effects when taking these drugs, I had no problems coming off them. In fact, apart from the slightly increased fear of it coming back, it was a relief to stop taking them. 

    My moods and my tiredness improved when I stopped, although I still get joint pains throughout my body and still have sweats and nausea. I agree that it is impossible to decide whether or not my arthritis might have been a problem irrespective of any treatment,  I am just glad to still be here 13 years on and leading a busy and fulfilling life.

    Please keep in touch and let us know how you fare. We are always here for you.

    Kind regards,
