Zoldex Implants


Re: Zoldex Implants


Hi Blovesdreamies

Before the menopause, oestrogen is mainly produced in the ovaries.  Zoladex (Goserelin) switches off this production by interfering with hormone signals from the brain that control how the ovaries work. This is known as ovarian suppression.  When the drug is stopped, the ovaries will usually start to produce oestrogen again and most women will re-start their periods within three months to a year after finishing treatment.

If your daughter stopped the Zoladex at the end of last year, it may be that her periods are returning.   If she is still having Zoladex the reason for the bleeding should be checked by her treatment team.  Despite the current pandemic, GP practices and breast treatment teams are still available.  Most people are being offered a telephone appointment in the first instance so do get your daughter to phone her treatment team or breast care nurse to discuss this.

We have a number of services and support designed specifically for younger women that may be of interest to your daughter if she is not already aware of this.

If you or your daughter would like to talk this through or have any further questions, do call our Helpline. Your call will be confidential, and the number is free from UK landlines and all mobile networks.

The number is 0808 800 6000 (Text relay prefix 18001).

Our opening hours are Monday to Friday 9am - 4pm and 9am -1pm on Saturday. Out of hours you can leave a message and we will call you back when we next open.

Please be aware that we will be closed on Monday 25 May due to the bank holiday.

Best wishes

Zoldex Implants

Good morning.

My daughter is has been administering the  Zoldex monthly injections since her diagnosis in 2018.  She completed her treatment finally towards the end of last year.  Due to current circumstances speaking to a GP or Oncologists is not easy, and as this may not be an issue she is reluctant to call them.   Our question is whether or not it is normal to have period type bleeding, intermittently, whilst on this treatment.  She was 23 at diagnosis and now 26.   Her periods were very irregular prior to her diagnosis, and fertility treatment to freeze her eggs was not very successful (only 1 egg viable).  Should we be concerned about this odd and random bleeding as we were told ovarian suppression would stop periods.  Thank you.
