XITYWELL 10MG Tablet works by increasing the level of a chemical called serotonin in the brain. This improves your mood, relieves anxiety, tension, and helps you sleep better. It has fewer side effects than older antidepressants. It usually takes 4-6 weeks for this medicine to work so you need to keep taking it even if you feel it is not working. Do not stop taking it, even if you feel better unless your doctor advises you to.
