medication

Good morning everyone I have to have a rant. Today i went and got my new prescription of Arimidex and guess what it has gone up. Give me  break I work full time, used my private health cover for all my treatment so out of pocket as not all covered. Ok my choice but I have to take this drug for 10 years and it keeps going up, what do you do. I tried Tamoxifon it is cheaper and for 2 months but made me feel anxious and if you listen to my husband a bitch. I feel better on Arimidex even with all the joint pain. I feel like I can't win a trick why are these drugs so expensive. This has really pissed me off as I feel I'm being penalised continually
Thanks for listening.
