Side effects registered for Venlafaxine

The FDA has forced safety related drug labelling changes regarding Efexor.
Please refer to
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.
