While I don't doubt that those medications could cause mood problems and actions because of them, I do wonder how many people felt depressed or had had suicidal feelings in their past before the studies began. I have bipolar disorder as well, and have had suicidal thoughts before medicated and while on meds (when the levels were too low) and I (personally) don't blame my medications. My asthma medication happens to list wheezing as a side effect, but how many people with asthma were already wheezing?
