Been taking tamoxifen for about 9 months & in last couple of months noticed symptoms suspicious of diabetes , thirsty , peeing a lot & tiredness . I need to get it investigated , I'm not overweight nor at risk of diabetes . Only medication I take is tamoxifen , never occurred to me that there was link between tamoxifen & diabetes until I did some research , there is a well proven evidenced based link . Some articles talk about need for monitoring , especially if you are in 60s . Wondering if anyone else is experiencing this ? also feeling a bit angry , yet another example of side effects not explained or taken seriously .
