Anastrozole and ibandronic acid side effects

I was diagnosed with breast cancer in November 2020. I had 6 rounds of chemo (3 x EC and 3 x Docetaxel), I had a mastectomy in May 2021 then had herceptin injections. I was prescribed anastrozole and ibandronic acid which I have been taking for almost 2 years now. I didn't think I had any side effects from these tablets however, I have recently been diagnosed with high blood pressure (which having googled it can be a side effect of the pills) and also diabetes. My blood sugars are 114 which is more than double what it should be. Again, I googled it, and it said that there is a link between taking anastrozole and getting diabetes. 

Do you know if my recent diagnoses could be due to the pills I am on and should I stop taking them?

Thank you in advance

  • Hi Eiluj,

    Thank you for contacting us and welcome back to the online community. I’m Lorna one of the cancer information nurses specialists on the support line.

    I’m glad to hear that you have been recovering well following your treatment for breast cancer, but equally sorry to hear that you have developed high blood pressure and your blood sugars have been rising.

    You don’t mention if you have been diagnosed as being diabetic.

    It can be a worrying to discover that some medications can have unwanted side effects. Some treatments for breast cancer can cause an increase in blood pressure and blood sugars. This information may help.

    It’s difficult to say if these symptoms have been caused by anastrozole or ibandronic acid you should speak to your GP who can offer advice and support and monitor this for you. It might also help to talk to a Boots Macmillan Information pharmacist they are specially trained to give advice on any cancer medications you are currently taking.

    If you are thinking about stopping your medication you should speak to your consultant or clinical nurse specialist (if you have one) first. Everyone’s cancer diagnosis is different and it’s important that you understand what the risk would be if you do stop.

    I hope this was helpful but please know that you can call one of our nurses to discuss things further.

    Take care and best wishes,

    Lorna
