Get Celexa Online

Celexa (citalopram) is a selective serotonin reuptake inhibitor, or SSRI. It works by blocking the transporter that removes serotonin from the space between nerve cells, leaving more serotonin available to support mood regulation. It is FDA-approved for major depressive disorder in adults.

Most people begin to notice some improvement in sleep, appetite, or energy within one to two weeks. Meaningful improvement in mood typically takes four to six weeks of consistent use at a therapeutic dose. Your physician may adjust your dose if you have not responded adequately after several weeks.

Common side effects include nausea, dry mouth, drowsiness, increased sweating, tremor, and sexual dysfunction such as decreased libido or delayed orgasm. Many of these effects are mild and often improve after the first few weeks of treatment.

Celexa carries a boxed warning about increased risk of suicidal thoughts in children, adolescents, and young adults during the early weeks of treatment. In adults, higher doses (above 40 mg per day) have been associated with QT interval prolongation, a heart rhythm concern, so regular dosing limits are important. Your physician will review your cardiac history and current medications before prescribing.

Celexa can interact with several medications, including other antidepressants, blood thinners, certain antibiotics, and any drug that also prolongs the QT interval. Combining Celexa with other serotonergic drugs carries a risk of serotonin syndrome. Always share a complete medication list with your physician before starting treatment.

No. Stopping Celexa abruptly or too soon can cause discontinuation symptoms such as dizziness, irritability, and flu-like feelings, and may lead to a return of depression. Most guidelines recommend continuing antidepressant treatment for at least six to twelve months after achieving remission. Any changes to your dose should be done gradually under physician guidance.
