Ok, thanks for the reply.
Well, it seems that your husband has developed what is called as Akathisia ( extreme degree of retlessness ) , which is a common extrapyramidal side effect of anti psychotics ( olanzapine is an ani psychotic ) , and anti depressants such as venlafaxine .
Since venlafaxine 's dose has been increased in the past 8 days , plus he has already been placed on an anti psychotic such as olanzapine , so this has summed up to cause akathisia .
So, in this case , what is required is that you contact your psychiatrist and ask him to wean all the drugs , and eventually stop all drugs , most of the times after such stopping of drugs , akathisia on its own resolves , but , sometimes , a psychiatrist may put the patient on a benzodiazepine such as clonazepam or beta blocker such as propanolol , or many a times an anti histaminc such benadryl is also used to treat akathisia .
Kindly look at the links below for better understanding of akathisia and the treatment of it.
So, i suggest that you discuss this with your psychiatrist as soon as pssible , and get all the drugs ommiitted for sometime, but slowly tapering them to avoid withdrawal symptoms , and once the akathisia resolves , then these drugs shall be re introduced , but in smaller doses.
I hope this helps..
I wish your husband rapid recovery to the best of health.
