Does Taking Cymbalta Cause Drop In BP Level?

When I stand up my blood pressure is dropping, this morning I got up to fast, everything went yellow meaning my vision, I fell! In a few seconds I got up! My blood pressure has been to low for a few weeks now, but only when I stand up! I have had this before and was told to drink lots of water by my dr, these past few weeks the water does not seem to be helping, I have DDD, fibro, bum knees and hips, I take many different meds for these problems, the only new med that has recently been added is cymbalta, could cymbalta be causing the low blood pressure?
