Tamoxifen - rare severe allergic reaction

Hi everyone, I was taken off tamoxifen 4 weeks ago due to a rare severe allergic reaction . I took for just over 3 weeks and from the first tablet I felt extremely unwell, about 15 days in my throat started to swell and I had difficulty breathing, I started to get covered in hives at night (the hives seem to be heat sensitive) I was advised to continue taking by BC Nurse and gp. When I started my radiotherapy my radiologists could clearly see how poorly I was (just over 2 weeks later) told me to stop taking tamoxifen immediately! That was 4 weeks ago. I am still getting hives if I don’t take antihistamines. I have my ONC app tomorrow and wondered if any one has any advice on what to expect next, treatment wise? What questions you would ask? Thanks for reading everyone and look forward to hearing the advice you might have for me, big hugs Sarah xxxxxxx

Goodness Sarah, that sounds awful

 

As you cannot take tamoxifen, it is likely you will be offered one of the Aromatase Inhibitors (AI), which work in a different way but do a similar job.  My understanding is that if you are pre-menopausal they will probably want you to have zoladex injections (monthly) to put your ovaries to sleep (even if you have had chemo and they shot) and this can have its own side effects issues.  Some ladies choose, or are advised, to have their ovaries removed if this is the case rather than have the zoladex jabs/implants.  This is something you could discuss with your consultant.  Remember you have choices here, so don’t be afraid to ask questions.

 

You might also want to ask them how beneficial they believe the Tamoxifen or AI to be for you (e.g. if they use Adjuvant to calculate benefits) as this might impact the deicsion you and they agree on.

 

I hope you get some good advice and that whatever the outcome you keep well.

I think that’s a really good idea to ask about the ‘binding’ ingredients - I nearly suggested you ask that, but then changed my mind.  I know that here is a liquid form of tamoxifen avaialble for people who cannot take the tablets due to allergies/intolerances, so may be worth asking about that.

 

let us know how you get on.

Hi Sarah,

 

They can be so annoying these doctors!  One thing at a time, let’s do this before we think about that… and not realising we put two and two together to make a HUGE number.

 

The first thing to say is that three weeks won’t make any difference in the scheme of things, so try not to let that worry you (at the start it used to terrify me even if if it was a one day delay but I now understand better and am a lot less anxious - the difference 3 years makes!!)

 

Concentrate on getting rid of this abscess and keeping well, and when you go back to see him your list of questions will be so perfected that he has to answer!

 

Take care and don’t be afraid to ask more questions in the mean time x
