				Anyone switch from Arimidex to tamoxifen?
			 
 I just about cant stand another minute on Arimidex!
 The knee pain is horrible. I feel like I'm 100 years old. I have pain in my lower back too, but the knees are the worst.
 Moving helps and hurts...I have pain just laying in bed.
 
 After a year of trying to adjust, my onc switched me to tamoxifen. I haven't started taking it yet. I'm taking a week or two off to see how I feel without it.
 
 Anyone have experience switching with positive (or negative) results?
 
 Thanks

 Dee,
 I don't have experience with tamoxifen but someone else on the board had once noted that they take their pill at bed time and they've had no issues on it.  Sorry I can't offer more input but hopefully others will jump in and give their take on the matter.
 
 Good luck!

 Dee, I have not made that switch but I do have some experience with SEs from Arimidex.  It was darn near crippling the first time I took it.  I went off it for a month and restarted it and things were much better but ultimately, I discontinued it because I am not ER+ (I have a wacky HR status) and they aren't sure it will benefit my PR+ status.

 Hi Dee,
 Why wouldn't your Onc put you on another AI like letrozole or aromasin?  I was on tamoxifen for 4.5 years and hated every second.  I was on letrozole for 5 years the first time and 4 years this time so far.   Much better for me than tamoxifen, but everyone is different.

				Re: Anyone switch from Arimidex to tamoxifen?
			 
 Dee
 Trying a different Aromatase Inhibitor is an option. If the oncologist decides on Tamoxifen you have to be aware that Tamoxifen is an inactive prodrug. It becomes an active drug, Nor-Tamoxifen in your body using an enzyme called Cyp-2D6. Drugs that inhibit this enzyme prevent the formation of this active form.
 
 There are a lot of these drugs but many of the anti-depressants ie Prozac (Fluoxetine) Paxil (Paroxetine), and Wellbutrin (Bupropion) do this. So does Quinidine but Quinidine is a heart drug and I doubt you would be taking this.

				Re: Anyone switch from Arimidex to tamoxifen?
			 
 I was on Arimidex for 8 years. Had to stop because of complicated bone issues. Onc put me on Tamoxifen and I had no discernable side effects at all.
 Give it a shot!

 I had started on Arminidex and had to make a switch.  The headache pain was severe.  Onc then had me try another AI which was Femara which worked find.Wishing you best of luck with new treatment.
