Reviews for Anastrozole to treat Breast Cancer
Review by Jacklink (taken for 2 to 5 years):
Arimidex (anastrozole): I've been on Arimidex for 4 years. Side effects are insomnia, joint pain, painful sex or no interest in sex, forgetfulness, anxiety and depression. One year to go and hopefully I will not have to take it. Maybe still on it because of a family history of breast cancer.

anastrozole: I have been taking Anastrozole for 1 and half years now for breast cancer. I have been having problems with my hands, stiffness of legs, short of breath, insomnia, thinning hair, weight gain and really bad hot flashes. I am going to ask my doctor about my chances of returning breast cancer if I stop taking this or try something else.
Arimidex (anastrozole): Took tamoxifen 9 months. Extreme bruising. Switched to Arimidex. After 4 weeks, extreme pain in hand. Next severe headaches. Each month brought increased pain in thumbs, hand, feet, long leg bones. Joints hurt, wrists weaken every month. After 10 months became depressed and had insomnia. Finally, had enough and stopped. Within, 2 weeks long bone pain went away. I still have some knee pain, trigger finger, and wrist weakness and its been 3 months. Doctor switching to Aromasin next month.

Review by Roxanne&Philo (taken for 1 to 6 months):
Arimidex (anastrozole): I started taking the medication in March 2013 after chemo on the fall of 2012 and then radiation in Jan-Feb of 2013. I am experiencing joint and muscle pain. But as a migraine sufferer, it's a walk in the park. Whatever works to cure this cancer, I'm up for everything and anything.

Arimidex (anastrozole): Been taking Arimidex for nearly 6 years now. Side effects for me are joint & bone pain, weird feeling in my chest that wakes me up. Weight gain, hair thinning & occasional hot flushes. I take calcium tabs and alendronic acid for my bones. Apart from that I'm grateful to be alive.

Arimidex (anastrozole): I have had the hot flashes, and the weight gain. Not much of the other side effects so far. Not willing to keep gaining the weight, talked to my oncologist but he says the weight gain is not from the Arimidex. I know better, I have always been very very careful with my weight and going on this medication is the only time I have had the weight gain. I stopped it for 5 weeks and lost, went back on the Arimidex and the weight came back. I work out 5 to 7 days a week so I am very active.

anastrozole: 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.

Arimidex (anastrozole): Started taking Arimidex in June and have lost 45lbs. Vomiting and diarrhea have left me homebound. I keep starting and stopping this pill. Oncologist thinks I'm crazy, but when I stop the pill the vomiting and diarrhea stop. Just stopped taking it before Christmas and I'm feeling so much better. Have had two lumpectomies and a mastectomy. Don't want the cancer to return, but the side effects are too much for me.

Arimidex (anastrozole): I've been on Arimidex 4 years and 1 month, prior to which I took Tamoxifen for 5 months. During the first year I developed a frozen shoulder, which my oncologist said could be due to the Armidex, extreme joint stiffness which gradually subsidized and ended after 9-12 months, intense hot flashes which as of this year are lessening, insomnia, vision issues (detached retina - but am also very myopic), pronounced facial aging, dry skin (am 57 years old) and thinning hair. I also experienced depression and mood swings beginning 3 months after the start of Arimidex. I never took medication for it but am finding that it has also gradually lessened over the last 1 1/2 yrs.

Review by Trick NOT Treat (taken for 2 to 5 years):
Arimidex (anastrozole): I have been on Arimidex for 4 years 4 months. I have had the hot flashes, vision issues, bone density weakening, joint pain and stiffness, depression, mood changes, insomnia, back and bone pain, thinning nails (of already thin nails), weakness in hands and now, my hair in breaking off and drying out. My doctor wants me to hold on to the end of the 5 years. Not sure I can.

anastrozole: I was on Tamoxifen for 3 years until I had to have a hysterectomy and then my doctor switched me to Anastrozole. I only have 3 more months to go and I am marking the days off on my calendar. I have gained 30 pounds, my grip strength is gone. My hands and feet tingle often during the day. My joints hurt all the time. I can't begin to tell you how my lower back feels. If I sit for too long my joints get stiff and it's hard for me to get going. I will stick it out.

anastrozole: I have been taking anastrozole for almost 5 years this is my last 3 weeks. I have had side effects such as mild aches and pains, hair thinning, arthritis which I am not sure is due to the medicine but it did come on very soon after starting it. Serious lack of concentration and confused at times and in the last few months tingling in my left hand which is now in the wrist. I did feel extremely tired for the first year or so but it hasn't been all bad although I will be pleased to take the last one at the end of April 2012.

anastrozole: I have been on this medication for 4 months and have gained 20 lbs. I have terrible hot flashes and am tired all the time. I have not experienced joint pain as others have, but the weight gain is very uncomfortable. I am having a double mastectomy in 2 months and hope I don't have to take this afterwards.

Arimidex (anastrozole): I have been on Arimidex for just over a year and have experience basically no side effects. The only issue I have is my left hand and fingers tingle occasionally at night - enough to waken me, however, the doctor thinks it has more to do with Carpel Tunnel Syndrome - which I never had before. I am going to be 70 years old soon, am in excellent health and shape as I work with a personal trainer. Life is Good!

Arimidex (anastrozole): I started taking Arimidex about 4 - 5 months ago as a breast cancer patient. I'm supposed to take it for 5 years. The side-effects I've experienced are: insomnia, hot flashes, headaches, weight gain, joint pain, and severe loss of grip in both hands. My hands are stiff in the morning and evening, it's just crazy. Well, even throughout the day. I asked my oncologist about this and he said it was arthritis, which I do NOT believe. The onset was too quick. It was about 6 weeks after I started taking the Arimidex then the hand stiffness showed up.

anastrozole: I have been on Arimidex for 3 years and about 1 year of the generic Anastrozole. I had a horrible time at first with hot flashes and night sweats and also joint pains. But now after about 4 years I am doing a lot better. Hardly any hot flashes and night sweats. The joint pains have also subsided but I have started a walking program everyday that I really believe has helped me. I have gained about 20lbs in the past 4 years that I am trying to get off. I really think it is due to menopause and also the medicine.

Arimidex (anastrozole): Within a month of taking Arimidex. I had so much joints pain, I mention to my oncologist and he said it was arthritis, I said "No way" arthritis does not show up in one month" I stopped taking it after 1 1/2 years. I could not endure the pain.

Arimidex (anastrozole): Have been on Arimidex for 7 years as my oncologist says that the trial period has only been up to 5 years and she wants me to continue as extra insurance. The only side effect that I have noticed beginning about a year ago is hair thinning, and it is starting to bother me. Three of my friends who had started taking Arimidex the same time I did and who had other oncologists, were taken off the drug after 5 years. They had noticed hair thinning during the time they were taking the drug and it has reversed since they stopped usage.

Arimidex (anastrozole): I am starting my 4th year on Arimidex and have had wonderful results. I have had no side effects at all. I am now over 70 and am active and otherwise healthy. I am looking forward to many more years of continued good health.
