Thank you for your post.
A dry mouth and metallic taste in the mouth are not listed as a common side effect of tamoxifen. However, quite a few women on our forum have reported having a dry mouth while taking tamoxifen. You may find this link on tips for helping a dry mouth, useful to read. It might also be helpful to speak to your GP to see if they can offer any advice about how what may help.
Most people usually start to notice any side effects after a few weeks and they start to reduce or stop after a few months. Constipation can be side effect and it’s possible that the gurgling and the rumbling you have is due to constipation. It’s understandable that you are want to avoid having further problems with constipation. There are a few things you can do yourself to help in addition to what you’re already doing by drinking plenty and being as active as possible. You may also find it helpful to make an appointment with your GP and ask whether some laxatives may help, if you’re not using them already.

After my lumpectomy in January I was prescribed Anastrozole, but after only two weeks I had to stop taking it because it made me so ill and I was suffering dreadfully from anxiety and severe panic attacks. I’ve recently gone back to see my oncologist and asked to be prescribed Tamoxifen, because with the aid of CBT and Escitalopram my anxiety has improved. However, after only 4 days I find I have a very dry, metallic mouth - is this normal? I have also found that my stomach seems to be constantly gurgling and rumbling. I did suffer badly with severe constipation while I was having radiotherapy and it feels a bit like that, but I now drink plenty of water and I try to be as active as I can as I don’t want to go down that route again. Could you shed any light on this.
