Re: Letrozole Side Effects

Hi, there,

I've been on Letrozole for 4 years now and can honestly say that Vitamin D, Glucosamine and fish oil capsules plus  weight bearing exercise have worked wonders for the joint pain I experienced for the first year or so on Letrozole. I used to take Turmeric too but it gave me heartburn eventually so had to stop it.

Re: Letrozole Side Effects

I take mine at night (when I get into bed) started off in the morning but found it drained me - the nighttime regime is far better.
I started taking Letrozole in April yes life is a little different but nothing that I cannot live with and most of the side effects seem to have subsided or I have found a way to manage them.

I was scared at first worried sick that being on this medication would be the 'end' I think (well for me) is to not overthink what you read (be aware, yes) but do not let your imagine convince you that these pills (or any meds come to that) will ruin your life.
Of course, I would rather not be on them - just as I wish I did not have breast cancer needing chemo, surgery and rads but I did/do...life has a way of upsetting the apple cart.

Please try not to be petrified I know I was totally overwhelmed by ALL of the info I received when first diagnosed I would come home feeling more worried about the treatment than cancer.
Once you get started and begin to experience for yourself things will become clearer.

Lots of HUGE Hugs

Re: Letrozole Side Effects

Thanks Wendy, I appreciate your message.  I’ve over researched and now I’m petrified. Great to hear about taking at night time.  Take care.

Re: Letrozole Side Effects

It’s so good to hear about your last week.  I’ve just had a full hysterectomy last week and need to start taking medication this week.  I’m pretty fatigued after 5 ops in the last year.  I’m emotional at the moment….it’s good to hear my concerns are commons.  Thanks for sharing.

Re: Letrozole Side Effects

I’ve been taking letrozole for 2.5 years.  No side effects thanks to magnesium supps.  Initial BMD scan 2.5 years ago showed osteoporosis which was a shock.  I was determined to reverse this and have achieved this with regular jumping and skipping exercises while holding weights and, of course, regular calcium and D supps.  So osteoporosis is now back to osteopenia, which I’m stoked about.

Re: Letrozole Side Effects

Hi there

 

i have been on Letrozole 6 months now. In early days I did get joint pain but I added vitamin D and glaucosimin and also had a 2 week stint on acupuncture. These last few months I am back to normal with only the usual older age joint pain it’s definitely experimenting.

Re: Letrozole Side Effects

Hi,

Have been on Letrozole for two and half years and haven't had any problems with bone or joint pain. Bone density scans (which aren't at all scary) are recommended around the beginning of treatment, for a base line reading, and every two years after, while you're on it. This is because letrozole can make bones weaker because it lowers oestrogen. My bone density was low, osteopenia and osteoporosis, ((I had no idea) so I have needed to take Alendronic Acid tablet weekly and daily Calcium/vit D supplement to counteract it. This had helped and my last scan showed an improvement. My GP originally referred me for my first bone density scan as the hospital hadn't mentioned it - it was only that I had read up about it.

Anyway, I wish you well with your journey and hope that letrozole suits you.

Re: Letrozole Side Effects

I am just starting Letrozole. I have only been on it for a week. I've had a headache on and off with some nausea but nothing crazy.

I was very hesitant to the point of almost not taking the med at all due to the side effects. I wanted to know when did you start to notice the joint and bone pain? I honestly have other concerns too but I'll start with this.

Re: Letrozole Side Effects

I’ve been on Letrozole for 18 months. My main complaint was throbbing pain in my body all night. My oncologist told me to take Turmeric for the pain. I’m taking 2000 per day. I also take Magnesium and Fish Oil at the suggestion of others who take Letrozole. It really has helped.

Re: Letrozole Side Effects

Hi, 

If it was evidence based practice ( and I am a retired Registered Nurse so know a lot about this) then it would be standard practice across the UK for Oncologists to prescribe Vitamin D and calcium. They do not. Partly as they can be bought as OTC (over the counter) tablets or online. The NHS conducts audits to ensure practise is evidence based, this is quite rigorous. It is of course up to us as people who have had cancer to read up as much as we can to optimise our health and believe me, I have done this and still do. I find your comment quite rude.  
Regarding Oncology follow ups, my last one was telephonic and I wasn’t impressed as the copy GP letter I received didn’t reflect accurately what we had discussed. My next one due shortly is also telephonic. They are yearly.  I agree a physical examination in a face to face appointment is much better, but Covid19 has affected so much.

Re: Letrozole Side Effects

Hi Cumbrian and Surrey:

Having this forum shows that treatments and monitoring vary across the country.  Also, treatments are individualized. I did have one telehealth visit shortly after the first Covid lockdown, but my medical oncologist recommended an in-person visit a few months later with Covid precautions in place.

Notwithstanding the variations in doctor visits, research shows that Vitamin D and Calcium are necessary to prevent bone density deterioration. No matter how healthy we eat, with Letrozole known to negatively impact bone density, supplementation is recommended to combat the effects, so we can have good bone health at the end of the treatment.

Additionally, we have to advocate for our care especially when we have concerns. Expressing these concerns does not mean we not thankful, it means we want optimum care to promote our overall wellness. Recently, my 82-year old mom was sick with pneumonia (not Covid related) and was on a ventilator for about 5 days. She survived and is recovering. I can't begin to tell you the number of times I had to speak up at the hospital, and at the Nursing Home where she had rehabilitation before coming home. 

Best wishes to you all as you continue your treatments, and seek the best solutions for your care. Blessings, always.

Re: Letrozole Side Effects

Hi surrey

its not a debate....it’s evidence based practice to prescribe a combined vitamin D3 and calcium Supplement.......you just need to  do a basic search of the literature to see this.  So having a good dietary intake in itself is not enough.
I do agree however that 6 monthly check up are definitely not standard care.

Re: Letrozole Side Effects

Hi @YvonneS Seems to be different treatment times around the country, I am not going to see any of my treatment team every six months, in fact, all of my oncology appointments have been via telephone because of Covid which has made information gathering about my own specific case very difficult.

Yes, I have read all the leaflets provided and searched online but it is not the same as being able to sit face to face with your oncologist and ask those relevant questions specific to me.

I am on Letrozole started 6 weeks ago, again nothing but a leaflet, bone scan before I started them, and the promise of Vit D at the end of rads - if not for places like this I would have been largely in the dark. I accept GPs, Doctors etc need to be Covid safe, (but the nurses have worked through it) albeit wearing their masks and whatever - but they are seeing patients face to face...cancer is not something to be left for the patients to have to go searching for info, coming to terms with the illness is bad enough.
Don't get me wrong I am grateful that all my treatment went ahead but there have been HUGE gaps in the information and help I have received especially as I have gone through all of my diagnosis and treatment alone.

Re: Letrozole Side Effects

Hi Yvonne,

Just to add to this debate that Vitamin D and calcium as you say are necessary for bone health, but ensuring you have a good dietary intake should be enough. Regular weight bearing exercise is important too, as is avoiding smoking and excess alcohol. Vitamin supplements aren't the go to.

6 monthly checks by oncologists aren't standard care,  at least not where I live. Perhaps this is different in your area.

Re: Letrozole Side Effects

Hi Yvonne

thanks for you message. I had one bone density scan at the end of 2019 6 months after start of Letrozole treatment and nothing since. No advice and only 1 CT scan Feb 2020 and 1 ultrasound Feb this year.

I will be taking the clinic to task on the 29th next week as I am really cross with being dismissed by the nurses who never seem to be available when

Re: Letrozole Side Effects

Hi Rosemarie:

I am surprised too that you were not told about Vitamin D and Calcium. Letrozole negatively impacts bone density. You should have had a bone density test prior to the beginning of your Letrozole treatment. The medical oncologist renews the test about every 2 years to see how your bones are doing from the last test results. The goal is to avoid osteoporosis.

I see my medical oncologist every 6 months to monitor my Letrozole, and my surgical oncologist every 6 months as well. I believe that is standard care for breast cancer survivors, so please look into it.

At this point, Covid should not be an excuse to see your doctor in person. I hope you are able to take care of this, and I wish you the very best.

Re: Letrozole Side Effects

I’ve had no joint pain nor arthritis since having celery juice on an empty stomach every morning for 2 years now.  Good quality magnesium supplements a must along with calcium and vitamin d.  Don’t rely on your doctor, always back up any advice with your own research.  Compliment with an holistic GP.

Re: Letrozole Side Effects

Hi there,

just had a conversation with my GP who said my Vitamin D levels are extremely low (21) and has prescribed a massive boost that I have to take for three months only 1 tablet per week. Apparently I am also anaemic.

I only know because my GP insisted on a blood test, and he said we should all be monitored every 3 -6 months. He thought this was done automatically by the clinic.

He was not impressed that neither the oncologist nor the clinic nurses mentioned the need to take vitamin supplements during treatment with Letrozole and that I haven’t seen an oncologist for a year, all I get told is that I am “responding well” to treatment. How would they know as a telephone call by a nurse is useless and it was based on an ultrasound at the beginning of the year. I have never received anything in writing. 
Still, I suppose I mustn’t complain as there are people out there that are worse off and have had their treatment stopped. I think if I hear “it’s the covid” once more as an excuse for the NHS doing nothing, I shall scream!

Re: Letrozole Side Effects

Hi, please google DR AXE very helpful on vitamins! Magnesium will help with your joint pain! The reason i get my vitamins on prescription is because i had to educate my GP!!! They know very little about how a combination of vitamins work together. I did a lot of research and so glad i did as i am now pain free. Good luck

Re: Letrozole Side Effects

Hi, it is so annoying GPs and my oncologist never mentioned how important it is to take supplements while on Letrizole. I had to do my own research! I have been on Letrozole for 6yrs now with NO problems since i started taking calcium D3, K2 and Magnesium. (I had severe side effects in the 1st year and now free from pain!) Please google DR AXE on these amazing supplements especially Magnesium and remember to leave 2hrs between taking them. Good luck!

Re: Letrozole Side Effects

Hi, have been taking Letrozole since August 2019 and the side effects have got progressively worse, so I can hardly walk due to joint pain. I have not seen my consultant since February 2020 and when I have raised issues with the team at my local clinic I get fobbed off. My GP recently had blood tests done due to hair loss and gout-like symptoms and found I was suffering from Vitamin D deficiency and am now anaemic. This side effect of low estrogen was never mentioned and there is nothing in the leaflet that comes with the medication.

The Americans have been aware for at least 10 years that Letrozole can cause gout-like symptoms and vitamin deficiency. Why aren’t we kept informed?

I am due to see my consultant at the end of April so hopefully I’ll get some clarification

Re: Letrozole Side Effects

I was worried too about starting Letrozole and scared myself reading too much on side effects. I started 4 weeks ago and also started taking vit D at same time.  I was washed out in week 1 and could barely do anything but I had my COVID jab earlier in week so could have been a result of both things. Since then I have been fine and can’t really claim to have any noticeable side effects. I am doing daily exercise and Pilates stretching on demand which helps me. 
I will keep aware of the joint pain side. I take my tablet at night as I was advised that would mitigate any big hot flush impacts. I am sleeping heavier than I ever have. 
good luck with your journey.

Re: Letrozole Side Effects

I'm on letrozole for over 7 months now after a metastasis op.  I had Tamoxifen which was perfectly okay for me after mastectomy but as my Oncologist commented it did not worked well as it came back to my axillary lymph nodes after 4 years.  

I experienced the following:. Sudden ankle pain when walking but not all the time, it will recur at times, right hip pain similar to wrist pain recurring. When those pain happens I would be on the floor if I don't stop walking, that severe.  But it take only minutes when it happens & gone.  I had also a severe psoriasis on my face & neck & difficulty in sleeping or staying asleep.  Tiredness was bad.   I have wrinkles & dry skin, but I'm 64 so I don't fret with that. Just few days ago I noticed my toe nails are flaking.

I have osteoporosis diagnosed few years ago & Im in Prolia injection after a year of my osteo.  Prolia is 6 monthly injection.   

I'm in Vitamin D3, Calcium, Vitamin C, Magnesium & zinc.  It's too much to remember, through research of my own I'm  on Ultra Vitamin B complex & dropped magnesium since Bcomplex has enough magnesium & if I haven't eaten I won't worry taking my calcium too.

Now My pains gone maybe because of PROLIA,  my psoriasis controllable because if ELEUPHRAT, my sleep is sound because of PHENERGAN & taking Letrozole in the morning instead at night.    My tiredness negligible now maybe because if my VITAMIN B COMPLEX.  My skin I use liberally SOBOLENE moisturiser which is very effective for my dry skin.

My doc has some hit & miss prescription.  The worst was Tramadol Rapid.  I was throwing up & dizzy.

Through my demand to get doc referral to get MRI when I have pains,  I had discovered more, I have bulging disk.

Now I'm ok. I was back at work after few months on leave.  My tiredness still occur when I lack some sleep.  All I need now is regular exercise which I'm too lazy & unmotivated. I'm not big I'm just 52kg & 152cm tall.

I think, LETROZOLE is good.  It only needs some other means to ease side effects.  By itself, is a struggle.  Also taking Vitamins on a certain time & no contradiction with another supplement (i.e. V-B must be taken in the morning first thing on an empty stomach), to make it useful for the body systems.

Research on the net & see to it in  reliable sources.

It's doable!

Re: Letrozole Side Effects

Reabarnes:

Thanks for your information, I did not know they have magnesium vitamins prescribed. I will speak to my medical oncologist about it. I do have severe joint pain from my shoulders to hips, thighs, feet, and hands. In an earlier post, I had shared how massage therapy and exercise had helped greatly. However, with the Covid Pandemic, I had to stop my massages, and it shows. I was happy to hear your story about vitamins that work, and even though our bodies react differently, it is still good news. Best wishes to you, and thanks very much.

Re: Letrozole Side Effects

Yvonne, I take Lamberts MagAsorb, 2 150mg tablets per day, morning and night. I get these on prescription, also Adcal but don't take together, leave 2/3 hrs. With or without food. Also take k2 with food, good combination.

Re: Letrozole Side Effects

i talked about the benefits of magnesium for me in here about 12 months ago, still going strong.  Magnesium supports the muscle aches, which eases the pressure in the joints.  What I've been using to rid of the joint pain is celery juice, at least a cup every morning on an empty stomach 30 min before breakfast.  Celery is an anti inflammatory wonder food, as joint pain is inflammation.  Acidic foods will inflame the body, so trying to alkaline it through the diet really helps.

Oh the first one to mention Magnesium! Yes you must take the combination of calcium D3 K2 and the magical MAGNESIUM. I have been on Letrozole 6yrs. I literally couldn't get out of bed! every bone and muscle ached! Since adding Magnesium it disappeared! No more side effects!

Re: Letrozole Side Effects

I have been to chat rooms for the past nine years and am grateful for all the input each of you have given. I haven’t responded before now because I just don’t do chat rooms. So I decided to respond this time because I am making a big decision of possibly stopping letrazole. I'm 70 year old at this time. I was diagnosed in 2012 with estrogen receptive breast cancer. I had a left mastectomy with it being stage 1 and no recommended treatment following surgery. In 2016, 5 months before the five year mark, I developed cancer on the same side which became stage 3 and had gone into the muscle. Radiation followed. They put me one arimidex and after 3 months I stopped it because I could no longer remember how to do things in my work program (I was still working) and if I hadn’t had GPS I would not have remembered how to get to clients homes and back. Some 3 hours away. I tend to do a lot of research so read Dr. David Servan’s book, “Anti Cancer a new way of life”. He had been diagnosed with radical brain tumor and treatment twice and was told he had six months to live. He wasn't ready to die, as he put it, and researched ways to help himself. He lived for 20 years more. In 2018, I was diagnosed with metastases breast cancer of C5-C6 cervical cancer outside the spine. I had radiation and was put on Letrazole. Nothing more can be done.

On letrazole, the side effects started early. All of the ones that you all have mentioned. Yes I felt like the bottoms of my feet were like cardboard (someone said for them it felt like Dutch wooden shoes). The exacerbation to my joints was so bad that I could hardly walk or use my arms (shoulder pain). I’ve been on plant based diet for some time. I take supplements. I see integrative doctor who does acupuncture. He has kept me going pretty well until this 2nd year of letrazole. My oncologist told me that I’m not killing myself with letrazole but it will affect my quality of life. He told me to stop it until 9-4-20 at which time I have another MRI and CAT scan. It has only been 7 days and already the cardboard feeling has left, my joints are less painful, I can get up out of the chair and walk again. Nausea diminishing along with other side effects. I am considering stopping. I have been reading a book and saw youtube by Dr. Stephen Jenkinson on “Die Wise A manifesto for sanity and soul.” Steven Levine wrote book, “One Year To Live” which is very helpful too. A friend asked me a question recently, “Is everything better than death? I am contemplating this question but I don’t believe self imposed suffering is better for me. Death for me is (and I’ve meditated on death) like a compassionate being taking us back into their arms. I’ve written a manual for family and friends, called “transition from life to death, you can be prepared. These are my thoughts, take what you want and leave the rest. Best to you in your journey. Peace.

Re: Letrozole Side Effects

Not everyone reacts the same JL as I've been taking Letrozole for over 3 years now, with little or no side-effects at all! Occasionally very mild, barely noticeable joint pain which subsides very quickly. While I am tired, this could very well just be the product of all the treatment in the last few years. So I would definitely try it if I were you!

 

I started on Accord brand and haven't found much difference with the others, either. The pharmacist (part of a chain) took me aside one to explain they may not be able to get this one and when I asked why she said it was all down to costs. Apparently each pack costs £180.00! The current one is a Sun Pharmaceutical one. However, have heard of many others who favour one brand over the others.

Re: Letrozole Side Effects

Hi,

The brand is Cipla, only my second tonight so we'll see how I get on, fingers crossed!

I was taking to a friend of mine today who has been on the same and hasn't really suffered at all so it all depends I guess.
