There could be two reasons, first one more likely is high dose divan you are receiving, it tends to decrease blood pressure. So should discuss with physician regarding lowering dose. Also, carvedilol also decrease BP. Secondly I need to know your ejection fraction because it is low then it can cause low blood pressure as well. So currently dose of divan should be reduced.
