Lustral, known generically as sertraline, is a medication primarily used in the treatment of major depressive disorder, anxiety disorders, obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), and premenstrual dysphoric disorder (PMDD), among other conditions. It belongs to a class of drugs known as selective serotonin reuptake inhibitors (SSRIs), which work by increasing the levels of serotonin, a neurotransmitter in the brain that helps maintain mental balance. Available in tablet and liquid form, Lustral is typically taken once daily, with or without food. Like all medications, it can have side effects, and its use should be closely monitored by a healthcare provider to ensure its benefits outweigh any potential risks.
