Imipramine is a tricyclic antidepressant used to treat a condition called nocturnal enuresis (bed-wetting at night). It helps the bladder muscle to relax, while causing the smooth muscles at the bladder neck to contract, therefore increasing the ability to hold urine in the bladder.
It can also be used to treat symptoms of depression (low mood).
This medication may also be used for other conditions. Check with your healthcare professional if you are unsure why you are given this medication.
