Well I am not a professional but I am the wife of a 49 year old man who just committed suicide. A man who showed no signs whatsoever of depression, never treated for depression but was started on straterra two months ago, had irrational behavior, spoke with doctor increased the dosage, moods become worse, became violent, rage, abousive, I have two small children and was married for 21 years to him. Mid December we had a argument, he became violent, I left the home with the children, feared for their sagety. Later that night my husband committed suicide. Realize this was a man that loved us more than life, we had just purchased a new home. we were truly happy until Straterra was introduced. I am seeking the adivse of a pharmaceutical attorney.
