From personal experience i have known times when i have become agitated/aggressive due to feeling that people didn't care or i wasn't being listened to/invalidated.
However i do believe that medication may sometimes be needed to facilitate the process of dialogue.
It should not however be something that replaces dialogue because it is seen as a quick fix solution compared to dialogue with the sufferer.

Unfortunately the modern trend for tick box evaluations whereby the client is seen as being his/her illness as opposed to the illness merely being a part of who he/she is coupled with a dogmatically hyperbolic belief in medication and shortage of resources/quality interaction with clients ensures that quick fix solutions are embraced at the expense of solutions that may take longer to implement but be more effective in the long run.

Medication is certainly not a universal psychological or psychiatric panacea though it does have more than a small part to play in treating people with mental illness.

Ideally it should be used cautiously, and when dialogue and therapy alone can make a positive and significant difference to an individual and their problem only as a means where necessary of facilitating that process.
