Started on diazepam today how long does it take to work struggling with extreme anxiety i am taking for last three weeks 50mg sertraline?

Quick Relief: Diazepam is an anti anxiety drug that usually works right away. It is often used on a short term basis until your other medication starts to work. Talk to your doctor. You may need to increase the dose of your sertraline. The sertraline helps both depression and anxiety. It is usually a long term drug and can take up to 8 weeks to start to work. Hope this helps. Best wishes!
