My partner has been taking Apixiban for 18 months after being diagnosed with a blood clot on his lung. He has been fine on this drug apart from the fact he has had a couple of fainting attacks. The only common denominator is he has had a couple of pints, and has got up from bed to go to the toilet when the faints have happened! He goes down with such a crash and then feels very hit and clammy. Has anyone else had a similar experience whilst on this drug.
