Question: Effexor and weight gain
|pain in the sunshine stat - Wed Dec 14, 2005 1:39 pm||
I have been on Effexor XR for over a year I am taking 225 mg, my diet has not changed and I am active. I do not have a routine excercise plan, but I never had one either. I have blown up in my belly midsection. Can Wellbutrin by perscribed with Effexor XR?

Venlafaxine (Effexor), a potent inhibitor of serotonin and norepinephrine reuptake, is sometimes prescribed for patients with psychomotor retardation, hypersomnia, or resistance to other antidepressants. A short-term study comparing venlafaxine (Effexor) with fluoxetine (Prozac) found no significant weight gain with either agent. Thus, like SSRIs and unlike mirtazapine, venlafaxine (Effexor) is less likely to cause weight gain in the short term, although there are not enough data to comment on its long-term effects.
You will need to discuss the possibility of changing your medication with your psychiatrist.
