Sertraline hydrochloride is a medication commonly prescribed to treat various mental health conditions, including depression, anxiety, and obsessive-compulsive disorder (OCD). It belongs to a class of drugs known as selective serotonin reuptake inhibitors (SSRIs), which work by increasing the levels of serotonin, a neurotransmitter that helps regulate mood. This medication is typically taken in pill form and can be prescribed for both adults and children. While it can be effective in managing symptoms, it may also cause side effects such as nausea, insomnia, or changes in appetite. It's important for patients to discuss any concerns with their healthcare provider.
