"beware this drug! i experienced the most horrendous mood swings and extreme anxiety while on this drug. the side effects took a while to develop but once they did it was truly unbearable. i had no idea why my personality was changing so drastically. it was truly terrifying. i wasn&#039;t making the connection between this drug and my highly elevated emotions. i told my dr. on a whim about my terrible anxiety/mood swings and he immediately took me off of kariva. within a week i was feeling back to my normal self. it has now been 4 months off of kariva and i have not had one mood swing or case of anxiety. i would never recommend this drug to anyone. as far as i&#039;m concerned, it should be taken off the market permanently."
