Questions & Answers

Where to buy arimidex or femara over the counter in the U.S.?

You can not buy arimidex and femara without prescription in the US, Canada, UK and most other countries in the world. You need to get a prescription for cancer drugs from your doctor before being able to access the meds. If you have a prescription, Walgreens, CVS, Walmart or any other online pharmacy will sell drugs for you.



I have been taking Arimidex for 1.5 years. At first the only side affect I had was night sweats. Now I am wearing a wig as I have hair loss, my mouth is always dry, my eyes burn due to dry eyes, my knees hurt and I get weird sensations in my toes. Wondering if it is really helping enough to have these side effects.


I have been taking arimidex for 2 months. Within the first two weeks my osteoarthritis has deteriorated from tolerable to barely able to walk. I can not stand for long periods. My knees get stiff each time I sit. I have received a series if Ortho visc injections and am hoping for a miracle. I must keep working for insurance coverage. I have vision changes, chest and muscle pain,also. I have added fosamax due to the risk of calcium loss since I was diagnosed with osteopenia at the same time as stage 1 breast cancer. I am expertiencing more fatigue with arimidex than after radiation. I am not sure if I can tough this out for five years!


Femara worked great for me. I had many unsuccessful attempts with Chlomid, injectibles and two rounds of IVF. After many failed attempts and/of losses we conceived and carried full term with Femara!

After having a dr prescribe hormones for me for 12 yrs even tho I only had a partial hystromectomy I developed breast cancer. When it was found I was a advanced stage 3 with a tumor just short of a size 8,in my chest wall and left lymnodes. After massive chemo for 6 months it shrunk to a size 2, then came the double masectomy and nodes removed followed by 30 hits of heavy radiation. This all began in may of 2013 and now in October of 2015 in total remission. I am so thankful to my Drs et however the side effects of all of the treatments and continued treatment of Letrozole are awful. I feel 90 and have sudden bouts where I can't breathe and hurt all over. I hate it.
