Re: Letrozole Side Effects

Hi Helzie, yes l was on letrozole pre surgery to try to shrink the lump but had the lumpectomy after about four months as it wasn't shrinking as quickly as my consultant wished. I have just collected my latest prescription and it is Activis instead of Accord (which I have been on since the beginning). I believe it is quite a good make. I hope so. I will keep you posted ladies!

Re: Letrozole Side Effects

Hi again Helzie,

My lymhnodes were completely clear - they removed 3 with the SNB. In my case the MRI did not show the size of the actual cancer.  There were two reasons, firstly because I had quite dense breast tissue and secondly because I had a lobular invasive. That devil grows tentacle like strands from the centre of the cancer (20mm) which are often only a few cells wide - hence the MRI could not pick it up. Post op (mastectomy, chosen by me, as I was not large breasted/best decision I ever made) the report showed the whole thing being 110mm.  That was quite a shock, as you may imagine. So chemo was a 'have to do' simply because of the size. My biggest surprise was the time it takes for me to recover from the chemo and radiotherapy. 

Hope you are recovering well.

Hugs

Re: Letrozole Side Effects

Hi Sue,

 

Ah! Fiinally I've met someone else like me!! Shortly after my (shock) diagnosis in late Sept, I was put on Letrozole in late October (like you I was ER+ 8/8) as a treatment and to shrink the mass pre WLE.  I could feel it  shrinking almost immediately and when I had the US in mid-January the mass had halved before my surgery in Feb!! I did inform them in Nov/Dec, including surgeon at the time of the noticeable shrinkage but they stuck to the original surgery time scale. In hindsight I should have been more insistent on an earlier op date or even requesting a US at the time but this was all very new to me then and I was on a steep learning curve! How were your lymph nodes following surgery? Mine revealed a micro and a macro (6mm!) infiltration out of the 5 which were removed. All others were clear.The med team were genuinely shocked at this. I should state nothing was detected on US or MRI in November! In addition all my scans then, CT and bone all came back clear-a great relief at the time. Of course this new revelation changed things and I felt I was back at square one again. Of course now I also had to have chemo, whereas before it was always going to be rads only, if even that.

 

I also see you'll be on Letrozole for `10 years. That's good since anything I''ve read suggests this is the optimum time frame, as opposed to 5 years.

Re: Letrozole Side Effects

Hello Lej
I have been on letrozole for 18 months and to start with got any old brand the chemist had in stock. I have found for me the best one is "accord" and now have it on my repeat prescription monthly. I found a huge difference in side effects between brands so it might be worth trying out some.
It's important that the side effects are manageable for a good quality of life ..as it .can be ten years of them now with new protocols .

Re: Letrozole Side Effects

Hi Helzie,

yes, I was on Letrozole pre surgery. The reason was not to give the cancer anything to live on, whilst I was waiting for it. It was an ER+8, i.e. the highest of the scale they measure receptiveness on. My operation was just over 8 weeks post biopsy results.

Post chemotherapy I am now on it for the next 10 years. 6 months and counting, lol....

Re: Letrozole Side Effects

Lej and Sue HS-From reading your posts, it sounds as if you were both on Letrozole pre-surgery, is this correct?  What was the purpose of this, pls?  Actually reading the thread I was reminded of the fact I, too had some (mild) hot flushes along the way, having been on it for for about 4.5 months in total. Onco told me to discontinue it during chemo.

Re: Letrozole Side Effects

Hi Lej

This is a challenging question to answer. I went through the worst of my hot flushes, etc., whilst on chemo and shortly afterwards. Now 6 months on Letrozole they have nearly gone away. I still have about 4-6 a day, but they are just me getting warm, rather than breaking out in a sweat. Like you, I was on HRT, which I stoppen in January 16, when I started on Letrozole before my mastectomy in March. I guess it can take some time for the symptoms to set in - I started my chemo in May...and during the treatment months and shortly afterwards the menoppausal symptoms were at their worst.

Our bodies are just so individual.

It might be worth trying a different brand - I am on the Teva one, but it might not help. And you may also exerience other side effects. My joint pains and tiredness got much worse, when I, for one month, was on a different one.

BCC has published a really useful booklet with regard to menopausal symptoms and it might be worth to download it and have a thorough read

https://www.breastcancercare.org.uk/information-support/publication/menopausal-symptoms-breast-cance...

I hope it might help a little..

Hugs

Sue

Re: Letrozole Side Effects

Hi all, l have been on letrozole for a year now and at first suffered few side effects apart from being a little achy and being a bit more tired. I then had a lumpectomy in July and and four weeks of radiotherapy in October/November. I already had a few hot flushes after coming off HRT and also suffered from insomnia however in the last few months both have got worse. I am just wondering if switchingredients to another brand of letrozole might help. I am currently on Accord. Has anyone got any advice or comments?

Re: Letrozole Side Effects

Yes you should but speak with your GP about it, You should also have had a baseline Dexa scan.

Beware  that calcium supplements can interfere with other meds so you need to checkwhen best to take them . it doesn't interfere with letrozole.

Re: Letrozole Side Effects

Have you had a dexa bone scan to show up if you have any bone thinning?   I had adcal prescribed after mine showed up slight thinning.  My pharmacist is useless in terms of ordering a specific brand for me and the other chemist where I live is just the same.

Re: Letrozole Side Effects

I started taking it at end of October and apart from tiredness (which could also be put down to stress of condition) and very minor joint pain if sitting down for a while, I'm fine with it. No apparent hair loss. I did continue with the brand prescribed at the hospital (Accord) and told my local pharmacist to order same and keep  some in stock! Wonder if I should be taking supplements to avoid osteoporosis, though?

Re: Letrozole Side Effects

I started with aching joints and bones especially wrists, shins and ankles after about six weeks and they wore off after about three months or so and I haven't had any problems since.  I occasionally feel a bit sick in the morning if I take the tablet on an empty stomach if I have to rush out first thing bit otherwise I am fine. When the aches were at their worst I took paracetamol which eased them a lot.  There is one brand which brings the aches back on, Activis, but all other brands are fine for me.   Good luck with it.  I think lots of people do take it without problems.

Re: Letrozole Side Effects

Hi Blacky

You probably won't have any side effects straight away, as it takes about 6 weeks to kick in. I'm getting some stiffness in joints after a couple of months, and now taking cod liver oil which is helping.

Re: Letrozole Side Effects

Hi, I just want to say that you will find posts on here of ladies with lots of different side effects from Letrozole and the other drugs but I have noticed lately that any side effects I have had seem to have settled down and I am not too bad at all.

I have been on it for 18 months .

I would be interested to hear if anyone else has found this to be the case.

Re: Letrozole Side Effects

Dear Sue,

I  am 58 years old with normal weight and I have been on Tamoxifen for about 18 months.  The side effects knocked me a bit initially - with joint pains and weight gain. I gained about 4,5kg in 2 months. I tackled this by increasing my physical activity to 1 hour per day and removing all sugar and glucose from my diet.  I have regained my normal wieght and I have managed to clear all my joint pains.  I feel very well and my energy levels are good too.  I am still slighty hot at night which seems to be related to how many coffees I have had during the day..  Wine also adds to the hot flushes and I have tried to cut down on my wine consumption.

 

I hope that this is helpful..

Re: Letrozole Side Effects

Also I've been told that it takes about 6 weeks to kick in, so you may not notice anything straight away. Then if you do experience anything, it peaks at about 3 months. So after that, it should settle and ( I'm hoping )doesn't get any worse.

Let you know whether that's true or not!

Re: Letrozole Side Effects

Hi bluelayla

ive been on Letrozole for a month now and have felt a bit more tied with some aching joints but manageable generally.  I take it at night now which is better as am less achy in the day. Do have fluctuations in temperature but again these are manageable. I think the side effects lessen as time goes on so I am hopeful. I keep thinking that it's keeping me safe while I wait for surgery so can put up with a bit of discomfort! Good luck. Emma xx

Re: Letrozole Side Effects

Hi Sue C and poppyj

 

Thanks for the words of encouragement. I know that it will help to keep the cancer away and am hoping that thinking about it is worse than actually taking them.  I plan to start on Monday and will make a note of how I feel so that I can monitor the side effects and will then have something constructive to go back to the doctor or specialist.  That's a great idea and one I probably wouldn't have thought of so my thanks.

 

Will keep you posted and try to be optimistic, not something I am naturally good at!

I've been on letrozole for about 3 months now and although there are side effects (for me mainly achy joints ) its not so bad. It's definitely manageable. Try and remember that its keeping that horrible c away xx

Re: Letrozole Side Effects

Hello Blueleyla

You may not have any, or all the side effects mentioned. Suggest you persevere with the Letrozole for a few months and if you do have symptoms mentioned on the leaflet, ask your specialist or GP to change you to a different brand as they do vary despite all being called Letozole. I would try keeping a daily diary and note down how you feel each day just to monitor how they are affecting you.

Hi Everyone

I had a lumpectomy at the end of December and went for my check up yesterday which went well.  I now have Letrozole and have read the side effects leaflet and the posts on this site and I am now really anxious about taking them. I know they are meant to help but the side effects seems horrendous. Has anyone taken them and been ok? Could really do with hearing any positive comments

Re: Letrozole Side Effects

My 87 year old mother has been on Hormone Therapy Femara since August 2016 since she was diagnosed with stage 2 CA Breast. She is an Angina patient too. 

 

Initially she faced severe diarrhea and hot flashes but that has got sorted now. Her major issue is exteme weakness ie where she was able to walk for half an hour morning and evening now she can push herself to only 10 minutes. She has developed a tremor too in her right hand, Got her complete thyroid profile done too but that was normal. Her BMD Dexa was pretty good for her age but due to her Angina her Calcium supplement was reduced and she was also advised not to take her ibandronate. So her spine base pain is excruciating when she has to get up after sitting or even when she has to take a turn while sleeping.

Re: Letrozole Side Effects

Hi all

Letrozole side effects - I have a little story to tell, which may be of help to some.

Although, I guess it is not side effect clear - it does seem to depend on whose manufacturers Letrozole suits you best. Although the active ingredient is the same for all - the stuff they use to make up the actual tablet varies. And sometimes the side effects can be appearing or be made worse because of that.

I started with the Teva brand of Letrozole in February, before my op, chemo and rads. No problems...

Since October back on them. Initially on the Teva brand - again no issues - then they ran out of that one and I was given the Actavis brand. I became very depressed and had the most awful joint pains, starting to move around like a really old lady. So I researched......and it does appear that certain brands suit us better than others. After going back to the Teva brand - depression gone and joint pains gone.....

The Teva brand seems to be best for me - for others other brands may be best. So if you and your GP are up for it, it may be worth experimenting to find the brand, which gives you the least side effects.

Hugs

hi Sue D,
I did not need chemo & have the option of going onto AIs, but agreed with my oncologist to stay on tamoxifen. Since starting tamox 7 months ago, my weight has remained stable. I do watch what I eat, but not have made any significant dietary changes & have increased my activity levels.

Re: Letrozole Side Effects

I have been on Letrozole for just over a year and have suffered with aches and pains and hot flushes. I take 1000 mg of Evening Primrose Oil to help with the flushes and plenty of exercise, mostly walking, for the aches and pains. These remedies have helped. My main problem is that my hair didn't really grow back after chemo, my Onc thinks it's the Letrozole stopping the growth and says I can change to either exemestene or Tamoxifen to see if it will kick start the follIcles.. I would like to try Tamoxifen but hear that there is a lot of weight gain with it, I have osteoarthritis in my knees so dont want to put on weight. However, I feel so awful with so little hair that I might take that risk and just stop eating. Is anyone on Tamoxifen and managing to stay slim? Thanks. Sue

After 7 weeks on letrozole ( and zoladex ), starting to get very achy joints and muscles. I knew this was coming, but what is the best way of dealing with it? I'd like to think that exercise would help, but after walking this afternoon, I feel worse! Any suggestions out there??

Re: Letrozole Side Effects

Hi ,

I've been taking Letrozole for 2 years since diagnosis in November  2014 and awaiting a mastectomy in Feb last year.

My surgeon did warn me that I would experience symptoms of the menopause. I didn't worry because I had only had mild forgetfulness during my  actual menopause.

I was not prepared for hot flushes, joint pain, dry skin, hair loss, sleeplessness and loss of appetite,

My surgeon recommended expensive thick amd thin shampoo and conditioner on the internet, which didn;t work.

It wasonly when a new doctor asked if I knew I had serroboeic dermititis.?  No! but immediately the dry skin and itchy scalp were sorted. I put a upside down sink strainer in my shower drain to stop hair from blocking it,

I am awaiting a bone density scan results, but calcium tablets amd hay fever Cetrizine tablets daily, help with the joint pain and rashes.

The only other tip is to take the Letrozole at bedtime so some of the rubbish side effects take place as you sleep.

Hi Lorna

Have only been on letrozole for 5 weeks but have been having stiff and sore neck too. Thought I'd slept funny! 

Just a suggestion.....I also had a lot of migraines and considered beta blockers but wasn't keen. So my dr suggested aspirin. I take a small one(75mg) once a day and have done so for about a year and a half. In that time have only had 3 migraines, whereas before was getting on average once a month. 

Hope this helps x

Re: Letrozole Side Effects

Hello Kathleen54

 

I think what you are describing is known as formication. I had it for a while post menopause then it stopped,

I hope yours will soon.

 

Also, if your skin is only slightly dry it can itch severely, One of the best moisturisers for atopic skin conditions is Doublebase and it is available on prescription if your doctor thinks it an appropriate.

 

Best wishes
