I think my tinnitus is a side affect of anti-depressant medication. It is listed as a possible side affect. I tend not to notice it if I am busy on other things but comes evident usually at night while relaxing. I think in my case the tinnitus is caused by an over stimulation of brain neurotransmitters caused by the drug Imipramine for depression. Taking paracetamol reduces it by about 90% for 3 to 4 hours. However, would not recommend taking the paracetamol too often. learning to try and not focus on the tinnitus is probably best method of treatment. I imagine though that tinnitus may be caused by different things and everyone is individual so paracetamol may be not work for others.
