Welcome to Just answer !
Well you see almost all the anti depressants including effexor come with a warning before use that they may in rare users arouse suicidal ideas/thinking and even lead to suicidal attempts ( mostly inpulsive in nature ), irrespective of whether he /she is suffering from an underlying brain trauma.
So yes efffexor too can be linked to impulsive suicidal attempts , which is rare but possible , however brain injury has no established role or link in this, not yet.
And in such a case scenario i will suggest that the person shall be brought off effexor , which in fact being given at a very high dose , another reason which may proppelled the person to suicidal attempt and this effexor shall be replaced by another anti depressant like remeron or wellbutrin.
I am mentioning below a link , kindly go through it as it will enlighten you more about the link between effexor and suicidal ideas and attempts , albiet in rare cases.
Lastly i will conclude by saying that the possibility of the link between effexor and suicidal ideation should not be ta***** *****ghtly and so should be brought to light in front of the treating doctor so that he /she can make the necessary changes in the drug regime by looking and ruling out or in this possibility.
I hope this helps..
Wish you all the best.
