I am 44 and started taking Cymbalta in May for anxiety, depression, and lower back pain. So far, it has been a wonder drug. I feel so much better. My family is thankful, too. :) However, I have noticed a dramatic change in my period since started the drug. Previous to taking Cymbalta, my periods were like (and continue to be) clockwork -- always on time. They had slowed to approximately three days each and the discharge was normal to dark. However, since starting Cymbalta, my periods are more intense with more cramps and a flow that is bright red with some clots for about seven days. My question: Can Cymbalta change my menstrual cycle so quickly, and is it even the cause for the change in my period? Thanks!
