Effectiveness
How Faslodex Affects PatientsFulvestrant is a drug that is injected directly into the muscle and works by blocking the effects of estrogen in the body. It does not have any estrogen-like effects itself.
How Faslodex works in the bodyFulvestrant works by stopping estrogen from attaching to cancer cells. It does this by attaching to the cells instead of estrogen, blocking the hormone from binding. It also breaks down the cells' estrogen receptors so they can no longer bind to the hormone. This prevents the growth of both tamoxifen-resistant and estrogen-sensitive breast cancer cells.

Faslodex Reviews: What are patients saying about Faslodex?
5Patient Review
4/4/2014 I've been using Faslodex for almost a year now and I'm really happy with it. The initial side effects were a bit much, but they lessened after each dose. Now the only issue I have is some soreness at the injection site, but even that goes away if I walk around on the day of treatment. My markers are almost normal now too, which is great. I'm enjoying everyday activities again and feeling good!
5Patient Review
10/27/2016 I started this treatment on 4/20/15. My tumor markers decreased sharply at first, but have since gone up slightly and have now steadied for the last 4 months, which is encouraging. I've had bouts of nausea and times when I am too tired to move, but these pass and the good times outweigh the bad. I remain active, walking the beach in morning and horseback riding on weekends. I have excellent nurses and have had no ill effects from the injections themselves or issues with the injection sites.
5Patient Review
6/5/2015 My diagnosis is stage four, but since I started receiving these injections twice a month (Faslodex + Xgeva), I haven't experienced any pain whatsoever - not even at the injection site!
5Patient Review
6/3/2014 After just six doses of this medication, my stage-three tumor has shrunk significantly. I've been getting 500mg each month and have had no issues other than the occasional pain at the injection site.

7/16/2014 I was originally diagnosed with breast cancer in 2005 and it came back in 2012. I started receiving shots about a year ago and all tumors have been shrinking since then. The shots need to be warmed up beforehand or the pain will last for two weeks. My doctor and nurse are very good at making me comfortable during the process. Shots are not fun, but they're working so I can't complain too much. I have CAT scans every four months
4.7Patient Review
1/19/2016 I've been on this medication for about two years now. The hot flashes are really bad—I wake up drenched in sweat most mornings. I also have issues with fatigue and pain at the injection site, as well as headaches. The symptoms vary from month to month, and I haven't been able to figure out any sort of pattern. Thankfully, though, the cancer hasn't spread elsewhere.
4.7Patient Review
12/1/2021 I've been getting Faslodex injections for a year now, and my oncologist says everything is going well. I get two injections per month; they hurt where they stick you, but using a heating pad seems to help quite a bit. The only other downside is that my urine smells bad for three days after the injection, but I much prefer this method of treatment to the pills I was taking before.
4.3Patient Review
2/16/2015 To reduce injection site pain, I take 2 ibuprofen an hour or more before the shots, AND immediately before the injection, I take one dose of the homeopathic remedy arnica montana 30C. This has been really effective for me in reducing pain around the injection site.
3.7Patient Review
10/16/2019 For a little over a week after this injection, I could smell something burning. It was quite intense and made the pain I was already feeling much worse.
3.3Patient Review
5/31/2021 Faslodex has some pretty gnarly side effects, like making your pee stink to high heaven for at least a week post-treatment. Additionally, it dried me out something fierce. And I don't just mean externally, but also vaginal dryness, dry eyes, and an incrediblydry scalp. Right now my sinuses are so bad I have a headache, drippy nose, andsinus pain.
2.7Patient Review
12/30/2019 It has kept me NED for going on 6 yrs now. Bad things are that if you have a bad back, it will aggravate it. More frequent UTI's and bad fatique. It also causes painful scar tissue.
1.7Patient Review
6/24/2015 Has anyone taken Vaslodex while travelling overseas? I have a layover that will last more than six hours and am wondering if this is safe.
1.7Patient Review
10/6/2018 Unfortunately, this drug did not work for me. My tumor doubled in size while taking it.
