Hi there, thanks for asking. It is true this medication can cause mood swings. If you have found such a relation between your mood and the medication, you may consult your doctor to change the method of your prevention. Or if it is hard to find a substitute for this method, you may consult with your doctor to give you a medication (mostly from the class of SSRI
if there is no risk of bipolarity) or you may enrolled in some talk sessions to help you cope better with your probable difficulties. I wish you find a good way to deal with.
