I recently had a pulmonary embolism that caused a bit of lung damage, and so I was prescribed blood thinners by my doctor to prevent another blood clot from forming in the future. But when I went to fill my prescription, I was stunned at the cost. Both Xarelto and Eliquis cost me around $300 for a three-month supply. That may not seem like a lot to some, but I am retired and living on a fixed income. I have to skimp on my medications or give up other necessities in order to be able to afford them.
