[|AI|]  Hello, welcome to Chat Doctor. Venlafaxine is used for anxiety and depressive disorder. It improves these symptoms by increasing serotonin and nor epinephrine neurotransmitters in brain. It usually takes 3-4 weeks for this medicine to show its effects. In initial few days this medicine can increase some anxiety symptoms for that short term benzodiazepines will be helpful. Side effects like diarrhea and Chat Doctor.  At initiation of treatment, suicidal ideation has also been reported with its use, so it is important to meet your psychiatrist urgently. Wish you all the best.
