Antidepressants are medications designed to help people who are experiencing symptoms of depression. They work by balancing chemicals in the brain, particularly those that affect mood, such as serotonin and norepinephrine. By improving these chemical levels, antidepressants can help lift a person's mood, increase energy, and enhance overall well-being. There are several types of antidepressants, including selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants. While they can be effective, it's important to remember that they may take several weeks to show results and can have side effects. Always consult a healthcare professional before starting or stopping any medication.
