Do ED meds trigger mental illness symptoms?

I was talking to a Sista the other day and she informed me of several relationships that were in trouble. In all the cases the women were contemplating leaving or have already left their husbands. These marriages ranged in length from 2 years to about 60 years.

Unfortunately it was not surprising that the marriages were in trouble. The troubling issue was the cause of breakups. In each case, the husbands had demonstrated or had been diagnosed with mental problem, such as depression, paranoia, and hallucinations.

We wondered why it seems there are more cases than usual and only the men were inflicted. She posed a question that made me wonder, 'Could erectile dysfunction medication trigger mental illness symptoms?'. She had no evidence that any of the men had this ailment, it was just a thought since there is a bombardment of commercials for ED.

I have done some Googling and not have found anything to substantiate a positive response to that question, but then again there wouldn't be if no one has done the research.

So what do you think? Does this question have any merit?
