Worth asking your prescriber whether venlafaxine's small edge over SSRIs matters in your case, given it is also somewhat more likely to be stopped for side effects.
Reasonable evidence with real limitations. how we score evidence
Caveat on this rating: Limited to published trials, so publication bias cannot be excluded; funding source not verifiable from fetched records.
Pooling 26 randomized trials (5,858 participants), venlafaxine gave slightly higher remission (odds ratio 1.13, 95% CI 1.0-1.28) and response (odds ratio 1.17, 95% CI 1.03-1.34) than SSRIs, but about 41% more discontinuation for adverse events (odds ratio 1.41, 95% CI 1.10-1.79).

Questions
How strong is the evidence behind this?
Resolv rates this source "moderate evidence". Reasonable evidence with real limitations. It scores 68 out of 100 on our published rubric. One caveat travels with that badge: Limited to published trials, so publication bias cannot be excluded; funding source not verifiable from fetched records. The score is calculated from recorded facts about the source — study design, funding, publication venue, sample size, preregistration — not typed in by an editor.
What is the source for this?
Efficacy and tolerability of venlafaxine versus specific serotonin reuptake inhibitors in treatment of major depressive disorder: a meta-analysis of published studies — de Silva VA, Hanwella R (2012). Published in: Reputable peer-reviewed journal. DOI: 10.1097/YIC.0b013e32834ce13f. The full source is linked on this page so you can read it yourself.
Who paid for this research, and does that matter?
Study design: Meta-analysis of randomised trials. Funding: Funding not disclosed. Independence from the proponent is not recorded. Industry sponsorship is one of the most reliably measured biases in medicine, which is why funding carries real weight in the score rather than sitting in a footnote.
Is venlafaxine (Effexor), effexor FDA approved?
Yes — FDA approved for Major depressive disorder, Generalized anxiety disorder (extended-release only), Social anxiety disorder (extended-release only), Panic disorder (extended-release only). Approval is for a specific indication, not for everything the drug is prescribed for.
