More and more articles are coming out regarding medicines with side effects that cause mental illness. Did you know that Nexium, Klonipin, Singulair, Advair, Accutane, to name only a few all have side effects of mental illness? I was a victim of an arthritis medicine that caused symptoms of Bipolar for over a year, depression and suicidal thoughts. I encourage anyone who is taking any perscription medicine to read all of the side effects, you may find that you are not mentally ill. you are just being effected by your medicine.
