Concerned about the side effects of anastrozole

Posted by tinalove @tinalove, Jan 31, 2016

I completed all treatments for breast cancer but now I am supposed to take hormone blocker, named anastrozole. im concerned about the side effects. Has anyone here taken it and did anyone have hair loss?

An ingredient can not fluctuate 20% according to my pharmacist husband.

He is so correct. Per the FDA website they must be the same dosage and strength to be FDA approved.

When I realized that my sudden major increase in side effects after one year on Anastrozole may have been related to a change in manufactured… I found a pharmacy where I could revert back to Anastrozole manufactured by Accord ( the original generic). My increased side effects faded back to the original manageable and mitigated ones… mostly joint stuff and interrupted sleep ( awake 2-3 hours in middle of night).

While figuring this out I found a route to try the BRAND ANASTROZOLE … ARIMIDIX !

Even less side effects and especially sleeping through the night!

Generics are not regulated by FDA… they have their own regulation body but the main ingredient ( Anastrozole in this case ) can vary up to 20% in either direction and fillers can be very different.

The BRAND is tightly regulated by FDA and cannot vary in ANY way from pill to pill.

The brand has worked for me.

This is not true as to generics. (From the FDA website) FDA-approved generic medicines work in the same way and provide the same clinical benefit and risks as their brand-name counterparts. A generic medicine is required to be the same as a brand-name medicine in dosage, safety, effectiveness, strength, stability, and quality, as well as in the way it is taken. Generic medicines also have the same risks and benefits as their brand-name counterparts.

I’ve been on anastrozole about9 months; after 4 months I had had enough of the side effects— joint pain, hot flashes, trigger thumbs— and had decided to ask my oncologist to change my AI when things got better… all but right knee pain at night on and off and occasional hot flashes. After reading responses here I checked my prescription label .. CVS had changed the manufacturer that they used. This one works for me..the difference is phenomenal.

I just posted a few days ago about how my issues started after my brand was switched. I had only minor issues my first 15 months with Anastrazole. Long story short, my digging showed that the first 15 months were Accord, and then I was switched to Breckenridge. Starting again on Accord after a month break. However my cancer provider tells me that my aggressive palpitations that went away after 9 days off of Anastrazole were NOT related to the meds. Hmmmm , we will see.

I can’t find any info on that. If that is true, that would be very dangerous and people would be getting very sick on generics…any generics. I know that different companies use different fillers. Also, some people just do better on brand. I am glad that you found a solution that works.

Best to you too
