Venlafaxine (Effexor) is a new antidepressant which is now being marketed 
by Wyeth-Ayerst.  I know little about the drug, but have seen ads and 
patient information sheets on it.  It inhibits re-uptake of both 
serotonin and norepinephrine, with low affinities for M1, H1, and alpha and 
beta adrenergic receptors.  It has "weak" DA reuptake inhibition.  It has 
"low" potential for drug interaction.  It's main side effects are 
hypertension (!), nausea, somnolence, dry mouth, dizziness, constipation, 
nervousness, sweating, anorexia, and abnormal ejaculation/orgasm.

I have not yet used it, so can't add much more.
