The conditions are that the tumor is locally advanced or metastatic (when it spreads to other parts of the body), previously treated with an antiestrogen – regardless of whether postmenopause occurred naturally or was artificially induced.
In addition, this medication can also be used in combination with Palbocyclib. In this case, treatment is indicated for women in the same conditions as before, but who have breast cancer positive for the hormone receptor (RH) and negative for the receptor for human epidermal growth factor 2 (HER-2).
It is also necessary that, in this case, they have undergone previous treatment with endocrine (hormonal) therapy.
What is the mechanism of action of the active ingredient Fulvestranto?
The active ingredient Fulvestranto acts as a competitive substance, that is, it binds to the estrogen receptor and inhibits tumor growth in cases of breast cancer.
It prevents the production of estrogen, the generic name for hormones responsible for ovulation and the development of “female characteristics”. This is because this is one of the most responsible for the occurrence of breast cancer.
In this way, the substance causes estrogen to be temporarily eliminated from the body and thus stops the tumor from developing.
Is Faslodex hormone therapy? -Yeah . As mentioned in the previous topic, Fulvestranto (active ingredient of Faslodex) acts by inhibiting / blocking the effects of the hormone estrogen in the body.
Thus, Faslodex can be classified as hormone therapy – because the category includes medications that act by blocking or interfering with hormone production.
How does the package insert indicate applying Faslodex?
Faslodex is an injectable medication, applied intramuscularly (directly into the muscle). The package insert indicates that the injection is prepared and administered by a health professional, with medical supervision and in an appropriate environment.
In addition, the application must be carried out in the buttock region and done slowly – care is also necessary on the part of the professional due to the proximity to the sciatic nerve.
There are also indications that Faslodex can be administered in conjunction with Palbocyclib (drug substance). However, in this case, it is necessary for patients to be previously treated with LHRH agonists (gonadotropin-releasing hormone).
It is worth mentioning that, when used in combination, it is necessary to pay attention to the recommendations on the package insert of both – considering that they may have divergences, including in the dose. What should always be evaluated by a doctor.
Regarding the dosage in cases of monotherapy, the package insert recommends that 500mg be administered intramuscularly in 2 injections of 5mL (one in each buttock).
The interval of 1 month must be respected and an additional dose of 500mg is required after 2 weeks of the initial dose.

Treatment with hormone therapy is just one of the possible treatments for breast cancer. It is also common for people with the disease to need more invasive treatments, such as radiation therapy or surgery.
However, if precautions are taken properly (self-examination and medical follow-up for annual examinations, such as
mammography ), it is possible to discover the disease earlier.
Thus, it is often possible to perform non-invasive treatments, for example, the use of medications such as Faslodex.
