Fulvestrant injection will be given to you by your doctor or nurse. Try to keep your appointments so that you receive the injections on time.
The most common side-effects are feeling tired, feeling sick (nausea), and pain at the site of the injection.
A colpo d'occhio
Fulvestrant is an injection used to treat certain types of advanced or metastatic breast cancer in women.
It is an anti-oestrogen medicine that blocks breast cancer cells from using oestrogen to grow.
Injections are given every two weeks for the first three doses, then once a month into your bottom muscles.
Tell your doctor if you have liver or kidney problems, blood clotting issues, or if you could be pregnant.
Common side effects include feeling sick, tiredness, and pain at the injection site.
You must use contraception during treatment and for two years after.
Seek medical advice for leg pain/swelling (blood clot) or signs of an allergic reaction.
About fulvestrant
Tipo di medicinale | Un antagonista ormonale anti-estrogeno |
Utilizzato per | Cancro al seno nelle donne |
Chiamato anche | Faslodex® |
Disponibile come | Iniezione |
Fulvestrant is a hormonal breast cancer treatment. It is used to treat advanced cancro al seno and metastatic breast cancer. Advanced breast cancer is cancer which has progressed despite treatment, and metastatic breast cancer is cancer which has spread into other parts of the body.
Many breast cancers need the female hormone oestrogen to grow. The cells of these cancers have tiny areas called receptors on their surface, to which oestrogen can attach. They are called 'hormone receptor-positive' cancers. Fulvestrant works by blocking the receptors and this prevents oestrogen from reaching the cancer cells. This slows the growth of the cancer.
Before having fulvestrant
Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start having fulvestrant injections it is important that your doctor or nurse knows:
Se non hai ancora attraversato la menopausa, o se c'è la possibilità che tu possa essere incinta.
Se hai problemi con il funzionamento del tuo fegato, o problemi con il funzionamento dei tuoi reni.
If you have any blood clotting problems or bleeding disorders.
Se hai mai avuto una reazione allergica a un medicinale.
Se stai assumendo altri medicinali. Questo include qualsiasi medicinale che stai assumendo e che è disponibile per l'acquisto senza prescrizione medica, così come i medicinali a base di erbe e complementari.
How fulvestrant will be administered
Before you start the treatment, ask to read the manufacturer's printed information leaflet from inside the pack. It will give you more information about fulvestrant and it will also provide you with a full list of the side-effects which you could experience from having it.
Your doctor or nurse will give you the fulvestrant injection. He or she will give you an injection every two weeks to begin with (for the first three doses); after that it will be given once each month. It will be injected slowly over a couple of minutes into muscles in your bottom. For each dose, you will be given an injection into both buttocks.
Ottenere il massimo dal tuo trattamento
Try to keep your regular appointments with your doctor or clinic. This is so your doctor can check on your progress. You may need to have a blood test from time to time.
Fulvestrant injection contains a small amount of alcohol. This is usually harmless, but if you have ever had a problem with an addiction to alcohol, you should let your doctor know about this.
It is important that you do not get pregnant while you are having treatment with fulvestrant. Make sure you have discussed with your doctor which types of contraception are suitable for you and your partner. You should continue to use contraception for two years after your treatment has finished.
If you are due to have an operation, tell the person carrying out the treatment that you are having fulvestrant treatment.
If you buy any medicines 'over the counter', always check with a pharmacist that they are suitable to take alongside your prescribed medicines.

Importante: your doctor will discuss with you the possibility of more serious side-effects. These are listed below. You must let your doctor know straightaway if any happen to you:
Any pain or swelling in your lower leg. This is because taking fulvestrant can increase the risk of you developing a blood clot in your legs.
Any swelling of your face or throat, feeling short of breath, or a severe skin rash. These could be signs of an allergic-type reaction.
