EFFEXOR XR is known as an SNRI (serotonin and norepinephrine reuptake inhibitor) and is believed to help treat depression and the associated symptoms of anxiety by affecting the level of two chemicals in the brain-serotonin and norepinephrine. These two chemicals are thought to play a key role in depression and the associated symptoms of anxiety. Correcting the imbalance of these two chemicals may help relieve depression symptoms and the associated symptoms of anxiety-which can be a positive step toward getting your life back.
What about weight gain or jitteriness? In studies with EFFEXOR XR, there was a low incidence of weight gain or jitteriness (agitation).
Try to be patient about the treatment process. Just as depression, generalized anxiety disorder, and social anxiety disorder do not happen overnight, it takes time to feel better. It usually takes 6 to 8 weeks to feel the full benefits of EFFEXOR XR. Results may vary among individuals. But the best way to ensure that you return to feeling like yourself again is to take your medication every day, as instructed by your doctor.
The goal is to reduce or virtually eliminate your symptoms and get back to your life again. If symptoms of depression and associated symptoms of anxiety are interfering with your life, and you’re not where you want to be, ask your doctor about EFFEXOR XR, a treatment option that may help you get back to doing your favorite activities again.
