For Breast Cancer "Invasive Lobular Carc. Grade 2 Stage 1A. ER+PR+ HER-Oncotype DX 9. Lumpectomy & 21 days radiation. W/ generic anastrozole: Very strong bone and joint pain after 1 to 2 weeks in places I didn't think I had arthritis as well as in those places I'd previously "insulted" during my 64 years. Thought that if were to be my life, I'd rather die sooner rather than later. Med. Onc. told me all aromatase inhibitors would have same effect so put me on tamoxifen. 3 weeks into that - so far just sweater on and off, on and off."

Arimidex (anastrozole) for Breast Cancer "Stage 1 grade 2 invasive ductal carcinoma. Lumpectomy and radiation. The last 6 months of the 5 years on anastrozole I began to have hip and back pain. I stopped taking it October 1st and today is November 18th. I want to get back to my daily walk but have not been able to due to the difficulty walking. I do still walk the dog at night but it isn't easy. I have tried stretching and in some cases I felt it aggravated it. I even limp some days. It is very discouraging. I am taking 1 aleve morning and night but don't really like doing that either. I am hoping it gets better enough to walk which may make me feel better. I am 60 yrs old."

For Breast Cancer "I have been on Anastrozole for 13 months now. Initially I had some joint pain but that has subsided. A little weight gain, however after receiving a walking monitor for Christmas I have been on a walking program. I walk a minimum of 10,000 steps a day. The result has been a 17 pound weight loss since December. I feel terrific and am full of energy. I will soon have my 64th birthday and am overjoyed that I am cancer free and am able to manage the medication."

For Breast Cancer "Prescribed after Lumpectomy for breast cancer and taking this medication for 1 year, I've experienced extreme panic attacks, anxiety that often prevents me from wanting to leave the house, and insomnia. My symptoms were so severe, I could not function at work and took early retirement. I have discussed these side effects with my oncologist; his concern was more with flushing side effects than anxiety. I have 4 more years of taking this medication and honestly don't know if I'll be able to keep it up. I find myself having extremely blue feelings and without taking anti anxiety meds I truly would not be able to function as all."

For Breast Cancer "I began taking Anastrozole in November 2015 following breast cancer surgery and radiation. After one year, I began showing early signs of neuropathy. When questioned, my cancer specialist said he felt sure it was not due to the drug. A neurologist said the opposite. I was placed on gabapentin for the pain and tingling of the neuropathy symptoms. I also have been suffering from worsening back pain and recently had an MRI which shows degenerative disc disease. I also associate this with the anastrozole. I am discouraged about my quality of life declining since starting this drug. I wish my cancer specialist would have been more open about the side effects. I may have chosen a different path."

For Breast Cancer "I am reading about all of these side effects. I just finished my five years and it's not necessary for me to continue on with it. I suppose some of my achy feelings and stuff came from this drug, but I take a few others so I'm not sure. I haven't had any side effects no hair loss or thinning like many others that I've read about. One woman I met shortly after I got breast cancer said she did not take the drug as was recommended and not long after her breast cancer turned into lung cancer now it's inoperable so she urged people to take the drug. Thank you I hope your drug makes me live longer to be with my granddaughters."

For Breast Cancer "I've taken ANASTROZOLE for just over two years now. I find the fatigue the worst I’m just always tired no matter how well I sleep or how much I rest the fatigue is relentless so much so my whole life has changed I know longer enjoy the active life I had and I have gained a lot more weight even though I walk every day and try to do weight bearing exercises just doing the house work these days or going shopping is enough. The joint and bone pain gets me down too some days I can hardly bend down let alone get up it gets me down so add low mood to the list. I've had no support either I finished my treatment then was put straight on this drug and feel I've been left to get on with it. If it were not for the fear of the cancer returning I would quit this horrid drug every day is a struggle and I’m not sure if I can do another 3 years I want my life back."

For Breast Cancer, Metastatic "My experience with Anastrozole has been beneficial. Following a double mastectomy and removal of the majority of my right arm lymph nodes, significant chemo and radiation, I started Anastrozole in 2013. None of the side effects have been too bad or debilitating, so I am very fortunate and grateful for this drug for the significant benefits. I will have to stop in a couple of years and that makes me nervous! As so many reviews here are about major issues, it's important to know that's not always the case."

For Breast Cancer "I have been on Anastrozole since August/2012 and things had been going pretty well. It is now the end of February and I now have high blood pressure, shortness of breath, hand pain especially at night and in the morning when I can barely hold a comb to my hair. Also, I feel "pins and needles" in both hands. I am confused as to why the side effects are occuring now. At least I feel better knowing that others are going through the same thing."

For Breast Cancer "I have atypical ductal hyperplasia. Initially put on Tamoxofen, stopped secondary to multiple side effects to include osteoporosis and poor quality of life. Took 9 month drug free vacation before agreeing to taking Arimidex anastrozole. Hot flashes and insomnia have been dependent on what time of the day I take the medicine; worse if taken late afternoon/evening. Have had a return of joint/arthritic pain in hips/low back, shoulders and hands. Have fatigue, no libido and have gained 15 pounds despite being active and eating healthy. Short-term memory is poor and word recall is frustrating. I know many do well on this medicine but not sure if I will stay on it."

For Breast Cancer "I have been taking Anastrozole for 2 years and just in the past 3 months have I had any side effects. All of a sudden my knees ache, I had to have shots in my wrist and thumbs for tendinitis. I exercise regularly and could not figure out why this was happening until I researched the side effects. Has anyone tried Letrozole? Same side effects? I am only 53 and not really wanting to feel like I am 90. I am grateful to be alive but what are the real chances that this will re-occur? Right now I am on Anastrozole that is preventing recurrence, that caused tendonitis and trigger thumbs and was given Meloxicam for painful joints, so when does the medications end? So frustrated. Thankful for your input."

For Breast Cancer "I am new at taking anastrozle (30 days). For the past week or so I found it impossible to get up and around for work because I was so sleepy. I think it has increased my lower back pain and it has been hard getting up from bed due to pain and stiffness. My oncologist advised me to quit today until we can discuss alternatives. I am 59 and had a partial mastectomy and radiation."

For Breast Cancer "I started anastrozole one year ago. At first I didnt notice any side effects. Now for the past three or four months Ive experienced gradual increase in my joints. My hip joints, knee and hands, give me a lot of pain. I also have stiff hands when I wake up each morning, trigger fingers and thumb, it gradually gets better as the day goes on. Other side effects I have experienced is hair thinning, anxiety, insomnia, thinning nails, chronic diarrhea, thinning of the lower walls of my vagina causing a bladder prolapse and dry mouth. I have stopped taking the product and called my oncologist. He suggested Aromasin but after reading about the side effects of that it seems like I am going from the frying pan into the fire."

For Breast Cancer "Reporting in after being off Anastrazole for three weeks. Well, my joint pain is quite a bit better! Not a cure-all so far, but it's gone from being nearly intolerable to not so bad. I can get in and out of my car without feeling as if I am 102. Will start some exercise this week to see if that helps/hurts. See my oncologist in 2 weeks to report back to her. Like others have said, a little scared to be off the med, but had to see if it was causing all the misery. Will post an update in hopes that it helps others."

Arimidex (anastrozole) for Breast Cancer "Severe hot flushes, sleep disturbance, bone and joint pain, lack of concentration. Was getting Zoladex injections for 9 months then had hysterectomy. Have been on Arimidex for 7 months. Hope I don't have to be on it for up to 5 years. I don't think I could stick out these side effects."

For Breast Cancer "I have been taking Anastrozole for 2 years 2 months following a double mastectomy, Chemo, & radiation. I had trigger thumb surgeries on both thumbs the first year. I am a dentist, so not being able to bend my thumbs is not an option. My hair is very thin. My knees are so sore I can hardly walk when I first get up. Getting down on my knees is excruciating! I am an active person but I move like a 90 year old woman. I am thankful to be alive and thankful that this medication is available. However, if anyone knows how to help the knee pain, please share."

For Breast Cancer "Have taken ANASTEROLE for 8 months , following lumpectomy and radiation a year ago. After about 2 months, began to have severe hot flashes and insomnia. Eating more cold food and keeping air conditioning cooler helped. Symptoms followed such as exhaustion, low energy and low motivation. For past 4 months , have had extreme exhaustion , severe pain and feeling achy all over like having the flu. I have also had 4 bouts of severe stabbing stomach pain, followed by nausea and vomiting and painful elimination. Walking more than a few yards is painful and causes shortness of breath. I am experiencing severe depression and have crying spells. Last week my oncologist told me to stop ANASTEROLE for 6 weeks. I hope my symptoms decrease! But if so, I don’t know what will recommended in its place. I am very concerned about cancer returning!"

For Breast Cancer "After quitting Anastrazole/Arimidex for five weeks and then starting it up again, I saw my oncologist. Told her the joint pain had disappeared completely while off the med and then started up again within a week after starting to take it again. Told her I was scared to stop taking it and she said it was completely up to me. Tamoxifen not quite as effective and has its own set of side affects. So, that concerns me. In a quandary and need to make a decision. Joint pain back to the near intolerable stage. Keep telling myself "just a bad day", "too much moving around", "it will get better" or "I can take it". But don't think I can. Will switchto the Tamoxifen. Keep u posted . God bless, Ladies."

For Breast Cancer "I started taking arimidex in March of 2015 after being diagnosed with bilateral stage 1 Invasive DC. After lumpectomies, I received 30 radiation treatments , but no chemo needed. I have had many side effects including Depression, joint pain, insomnia, nausea, numbness in my left hand fingers. I was determined to stay with it. Two weeks ago I ended up in the ER with hip pain so severe I was vomiting and crying. I actually have a very high tolerance for pain. I saw my oncologist today, he said we want to improve your quality of life not hinder it. He took me off the arimidex and will start me on something else in 4 weeks. It was so nice to have a doctor actually listen and want to work with me. I hope I tolerate my new med better."

For Breast Cancer "Age 66. I had Stage IIA breast cancer, two tumors in the right breast, hormone receptive. I had a double mastectomy and seven lymph nodes removed (clear, thank God!). I dodged the Chemo bullet, but the side effects from the Anastrazole are terrible. Brain fog, fatigue, weight gain, severe hot flashes and now such joint pain and tendonitis of the hamstring that I walk with a limp. Got a cortisone shot ten days ago. Seemed to help some, but the pain came back with a vengeance after a week. I can hardly drive, which is required for my job (hospice chaplain). I have to work. Oncologist advised today that I go off for a week to see if the leg pain improves. If it goes away after not taking it for a week, I'll have difficult decisions to make."

For Breast Cancer "May 2014 underwent a lumpectomy stage 1 breast cancer. Clear margins, no lymph nodes issues. 20 treatments radiation. Oncologist started letrizole. 3 months terrible joint pain/difficulty rising . Oncologist then prescribed anastrozole. Vaginal dryness, no sex drive, nose cavity dry, NO joint pain. Insomnia. Difficulty loosing weight. 10,000 steps daily I loose! Take Vit D, calcium and others daily. SLIGHT bone loss last image, oncologist recommended PROLIA. Near end of taking anastrozole -6 more months to 5 years. After researching this drug take lifetime, shot 2 times a year, $1,800.00 yr to insurance or not! Advise from 3 health care specialist friends, going for second opinion DR that read my bone scan, I followed their strong advise to not take PROLIA. Felt the side effects researched/told were very severe / not worth the risk. More spinach, kale, calcium in food, and load bearing exercise. Hang tough ladies!"

For Breast Cancer "I have been on this medication for half a year. I was on tamoxifen for 3 and a half years but after I had my ovaries removed was moved onto anastrozole. Since starting my entire body hurts. My bones my hands my joints everything. Have been backwards and forwards to doctors who have not been much help, aside from the the pain emotionally it makes me worry I have cancer somewhere else. Some days I can hardly get out of bed with it. Some days the pain is just an ache other times just sharp pains that can be anywhere. I am preserving though, I figure I would rather have the pain that get cancer back so if this helps at all it will all be worth it. There are days that I am not so positive but only got a year to go... I am 44."
