The obvious sharp marginal trend reversal of Venlafaxine Total Prescriptions in 2004 to 2006 correlates with: -

2 “NICE Clinical Guidelines 23: Depression” published December 2004, issued new guidelines for treatment with Venlafaxine; 220.127.116.11 restricting treatment initiation to specialist mental health medical practitioners and in 18.104.22.168 reinforcing that venlafaxine treatment should only be managed under supervision of specialist mental health medical practitioners.
Both 22.214.171.124 and 126.96.36.199 recommendations were surreptitiously deleted from the revised prescribing advice issued 31 May 2006 at which point increasing venlafaxine prescription trends resumed.
