Thank you for your quick response and taking the time to send this update. Per the Eliquis -- I have been taking it for several years now and grateful to have it. I do take it in the AM and PM about 12 hours apart. There's been an MD change since it was prescribed but I do stay in contact with the MDs on these issues. Your advice to do so was spot on! However my current MD seems to take a more casual approach on these issues. My issue with the lightheadedness with Eliquis in the AMs has not been on going ... current focus is the Atorvastatin for several recent issues per that lately. Will check out the factors with women after I send this . And again thank you for the quick reply, the referral to more information and your concern.
