Is Pristiq effective for treating depression?
Yes, Pristiq (desvenlafaxine) can be effective in treating depression. It is an antidepressant that works by increasing the levels of certain chemicals in the brain, like serotonin and norepinephrine, which help improve mood. Many people experience relief from depressive symptoms when using Pristiq, but it may not work for everyone. It's important to talk to a doctor to determine if it's the right treatment for you.
