Deep Vein Thrombosis (DVT) Support Group
Deep-vein thrombosis, also known as deep-venous thrombosis or DVT, is the formation of a blood clot ("thrombus") in a deep vein. It can be caused by something preventing blood from circulating or clotting normally. Join the support group if you are coping with DVT and find others who are going through the same challenges.
Here is a copy paste from of the side effects similar as to yours
http://www.drugs.com/sfx/eliquis-side-effects.html
common (1% to 10%): Dizziness, headache, fatigue, syncope,
Common (1% to 10%): Cataract, conjunctival hemorrhage, eye hemorrhageischemic stroke, vertigo
These occur in 1-10% of patients with side effects. The rate of side effects among users of Eliquis is not provided, thus I guess that these are overall pretty rare.
I recommend that you monitor these sympotms carefully and go to E&R if these get worse. Often, the side effects of medicines appear early in the treatment while the body is adjusting to the medicine, but then decrease or disappear over time. If they get suddenly worse, I would recommend that you go straight to E&R. As an example, if your vision gets suddenly really cloudy then this is most likely due to bleeding in the eye and needs immediate medical treatment.

I once had a doctor adamantly tell me that a drug he was prescribing wouldn't interact with my warfarin. The pharmacist disagreed and my INR was all over the place the next week or so that I was taking the new (short-term) med. When I saw the doctor again, he actually asked "Did it have an effect?" which made it obvious that he really didn't know ... even though he'd been so sure about it when I'd asked before. I stopped seeing him... just didn't like that kind of attitude when it came to my health.
Anyway, I agree that you might want to ask your pharmacist. Most often I have much better information than my doctor and her nurses do but the pharmacist is spot on whenever I ask him a question.

The big question to me, is whether Nattokinase is a strong enough anticoagulant to keep my clot from growing... if so, I would not consider any of the major anticoagulant drugs... but I am not sure, so am stressed about it... I will take the enzymes in some fashion, with or without Warfarin... because they are clot busters, 4X as strong as Plasmin... and actually help your natural Plasmin work (activate), which, as said, none of the majors do at all. All my Docs Poo-poo anything not Big Pharma. I am still not sure what I will do... but I hope this gives you food for thought...
