How should this medicine be used?
Citalopram comes as a tablet and a solution to take by mouth. It is usually taken once a day with or without food. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take citalopram exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
It may take a few weeks before you feel the full benefit of citalopram. Continue to take citalopram even if you feel well. Do not stop taking citalopram without talking to your doctor, especially if you have taken large doses for a long time. Your doctor probably will want to decrease your dose gradually.
