"I Started Letrozole 5 months ago. I take it at night. My side effects have been minimal compared to what it is doing for me (hopefully) I started with terrible leg aches at night for a couple of months and they are now gone-- My hands and ankles are really stiff in the morning, my body feels a bit beat up, and I had a vaginal discharge for about 4 months that finally stopped. Also my pap came back abnormal due to the hormone changes my body is going through so don't freak out right away if that happens. All normal! My doc has also put me on Alendronate Sodium tablets once a week to help with my bones and to prevent bone cancer. I just started getting back into working out with some weights and tread mill and that is helping for sure."

"I have been on letrozole for 13 months, which I began after a lumpectomy of my left breast, followed by four months of chemo and four weeks of radiation. For many months my only noticeable side effect was fatigue. I always took it at night so this was not too much of an issue. Within the last few months, I’ve been experiencing increasingly more painful joint and muscle pain in my shoulders and arms. Sometimes ibuprofen seems to ease the pain, but not always. I’m hoping it doesn’t get worse, for it is not easy to ignore. And yes, I’ve had weight gain also... the 20lb seems to be the magic number, however , being menopausal this was occurring with me anyway. I have a very active job with a lot of lifting and walking but the weight gain won’t budge."

"I have been taking letrozole for over a year, and about six months ago developed hand, and foot tremors, very mild, but never has those before this drug. Had Lobular, did radiation, left breast, clean lumpectomy. Also had hair shedding, and vaginal dryness. It does beat the cancer coming back, but I feel like a very old 61. Will be talking to oncologist next month, maybe ask if I can take a break."

"Letrozole was successful in shrinking my tumor prior to surgery. I am now taking letrozole to prevent recurrence of breast cancer but am finding the side effects are impacting my life. I get so many aches and pains in my joints, coupled with dizziness, fatigue, and headaches. I am grateful to letrozole for helping to remove the cancer but feel that my enjoyment of life is reduced due to taking this drug long term."

Femara (letrozole) "I was prescribed Letrozole by the Oncologist after breast cancer surgery. Exactly one year on this medication I started having arthritis, which progressed to full blown Rheumatoid Arthritis. The Oncologist refused to acknowledge a link, and insisted I stay on the medication for five years. Common sense told me that the medication interfered with my immune system. I will be on medication for the rest of my life, to control the RA, taking injections every three weeks. I am positive it is connected to the Letrozole."

"I have been on this drug for over a year now. This is my update to a previous comment. I stopped it on the advice of my doctor, because of my hot flashes & sweats, joint pain. It was a month break. Started it up again, my hot flashes & sweats, were subsiding, now they are getting worse again. My joint pain is going away. Some nights I may sleep 4 hours max."

"I have been on Femara since 6/4/15 almost 1.5 years now. At first my only side effect was enhanced hot flashes and night sweats. I am post menopause. No real weight gain which has pleased my oncologist. I do however now have muscle weakness, joint pain in wrists, fingers knees. Also now have trigger finger in thumb. Have seen a rheumatologist and have been put on diclofenac for joint pain. Even she feels like my aches are from the Femara. The meds she put me on are not working. Get just as much relief from Aleve and Advil. If anyone out there has a solution to the joint pain, please write in."

"I had stage 2 breast cancer in 2004 took tamoxifen for 5 years and was then moved to femara. I have had significant bone and muscle pain; weight gain; severe hot flashes/night sweats; and brain fog, forgetfulness; however my 5 years of femara will end in June 2015 however I was under the impression that I would be taken off of this medication; however I have seen many post that show individuals on this medication for 8, 9 or more years. I am not sure what my oncologist has in mind for me. I was 46 when I found out and have had both breast removed and completed 5 months of chemo but I am still concerned to be without any medications for fear of my cancer returning."

"I was diagnosed with stage 2 hormone positive breast cancer December 2015. I had a bi-lateral mastectomy January 2016 just 3 days after turning 60. No lymph node involvement. I also didn't have chemo or radiation and started on letrozole in February. Didn't notice side effects at first. I think I was going through reconstruction with tissue expanders. This was very painful and pain meds helped. Since having my implants and no pain meds my joints ache, my memory is awful, tired, and hot flashes. Sometimes depressed for no reason and just don't feel like doing anything. Have lost weight by strict dieting and biking which helps. Now it's March 2017 and still cancer free. Also added another BP med and a cholesterol med and low dose pain med."

"I was reluctant to even commence taking Letrozole as my benefit score was 0.9%. After only a few weeks I had leg pains and brain fog. Then devastatingly my dental implants failed and I have had immense bone loss in my jaw causing tooth loss. My DEXA scan confirmed I am Osteopenic. I was only on Letrozole for about 3 months and it has ruined my life. I wish I had followed my instincts and never taken it. I had no dental implant problems prior to taking this horrible drug."

"Stage 3 breast cancer. Double mastectomy, chemo, Radiation. Started letrozole about 5 months ago. Severe joint and muscle pain especially in shoulders, arms and hands. 20 lb weight gain. Seriously hate this medication but afraid to go off it because supposedly it reduces my recurrence rate. I'm trying acupuncture for the joint pains."

"Had chemo every other weeks for 4 treatments, surgery, another 4 sessions of chemo then, radiation every week day for 33 sessions. Neulasta shots day after chemo, that was so horrible, excruciating body aches. I've been on Letrozole 8 months. Side effects have been, muscle aches, fatigue, some nausea, dry mouth, trigger thumb, hot flashes, weight gain, blurry vision, insomnia, occasional decrease in appetite, neuropathy mostly in my feet ( maybe from the chemo?). Is that enough? My doctor wants to give me a 3-4 week break but I'm scared to stop. I can live with these side effects if it keeps me from a recurrence. I am feeling better not quite as tired or nauseated. I'm glad I'm not the only one with the symptoms."

"Was diagnosed in Oct 2014 with endometrial stroma sarcoma and put on Letrozole 2.5 mg (UK). Small tumours near my liver have now disappeared and the main tumour has shrunk from 2.7 to 1 cm. Side effects have been very bad from nausea, dizziness, aches and pains (sometimes from head to toe), stiffness in all the joints, brain fog and tiredness. Yes, some days you wonder if it is worth it but then you look at the family and decide there is no option but to keep fighting. Taking loads of supplements and herbs which have helped somewhat and acupuncture. The insomnia is very hard to deal with - nothing seems to help at all with that. Now having a 4 month break. Oncologist suggested 1 month but after 1 month the effects are still there."

"My 2nd breast cancer 8/16, 1st 2005 DCI stage 1 Rt. breast. 2nd in left breast. It is primary, not metastatic but due to the large size tumor, Surgeon wants to shrink tumor to try a lumpectomy. On Femara 2 months and feeling very blessed. Sonogram follow up shows tumor shrinking and this allows me the holidays with family before surgery. I have the typical side effects; joint pain, daily hot flashes, nightly sweats, (fans everywhere, portable in my purse) some hair thinning so I keep in double braids to save vacuum & shower drains. I can't walk far at one clip due to fatigue so use a walker with seat to allow daily exercise. Changed diet & losing weight. Grateful for medication & will keep taking as long as tumor is shrinking."

"I started letrozole in May 2018 after chemo-mastectomy-ovary removal-radiation for stage 3A breast cancer. I was 32 at the time, I'm 38 now. I've taken the recommended 5 years of letrozole without (or rarely) missing a dose. The oncologist now is giving me the choice to stop or extend it, leaving it up to me. I'm afraid to stop. However, I do have osteoporosis now (at age 38). My feet/knees/hands have been stiff, and I have no libido (probably because of surgical menopause). I'd like to stop to see if I can kick the brain fog, but is it worth getting cancer coming back? It's a hard choice. This medicine probably saved my life up until now."

"Has anyone had eye problems with Letrozole. I've been on it about a year and a half. Every so often I can't see out of my right eye at all and the color is a deep maroon.....very scary. My retina doctor said there was no bleeding. I have wet macular degenration in the right eye and I read Letrozole can cause the pulling of the vitreous in the eye on the retina causing the retina to change your vision and also small retina hermorrhages. I'm so afraid of losing my vision. Has anyone ever had this happen to them? Does anyone know if there are other safer options to prevent my Stage 1 breast cancer from coming back other than Letrozole?"
