Imdur - Does this medicine cause mood swings?

Emotional lability is considered a common side effect of this medication affecting 1% to 10% of patients.
Common to very common side effects if experienced subside within a week to 10 days approximately in most patients.

I recommend, that although, changes in mood, emotions, feelings, laughing, crying, etc. are as I mentioned considered a common side effect, if you experience emotional lability inform your Dr..
