Could Benadryl Allergy Liquigels cause A-FIB? I have a history of A-Fib and am on meds for it. My allergies are in full force so I started taking benadryl for the past few days, 1 or 2 liqui gels a day and this morning I went into A-fib.
Lady from NJ on Jan, 24, 2013:
I am a 57 year old lady from NJ. Never had any issues with my heart EVER till I took two Benedryl the other night and woke up in the morning with Atrial Fibrullation - heart beating 610 beats per minute, had to check into emergency room and the problems that ensued were horrible.
This stuff is DANGEROUS and it definitely CAUSED the ATRIAL FIBRULLATION however you spell it.
