CoKAzNReBel: the good news is, presuming your heart was OK before, will likely recover back to normal. I know 'cause I've been there. Same symptoms. Started with fainting, then in the hospital they figured out it was ventricular tachycardia and prolonged QTC. Loperamide was the only drug I was on (no cimetadine). There are at least two published cases that I know of in the literature where this has happened as a result of megadosing loperamide. This is absolutely true. Stay away from the lope. It's not worth it.
