Side effects registered for Venlafaxine

The FDA has forced safety related drug labelling changes regarding Efexor.
 
Please refer to http://www.fda.gov/medwatch/safety/2000/mar00.htm#effexo
The changes acknowledge the existence of severe discontinuation problems which are both dose and time related and that the evidence of the problems has been obtained from a retrospective survey of the clinical trials database.

This would tend to indicate, in our opinion, that venlafaxine should be considered as a second line antidepressant for resistant depression.

Caution should be used in the elderly, those at risk of CVAs or the hypertensive.

About 40% of patients taking venlafaxine suffer nausea and vomiting; thought to be dose related i.e. more severe with higher doses.
