Celexa (citalopram) is a selective serotonin reuptake inhibitor (SSRI) antidepressant. It increases serotonin activity in the brain, which helps regulate mood. Celexa is good for treating depression and anxiety. Side effects are less likely to happen compared to other antidepressants; however, it is not the best choice for people with heart or liver problems.
Why is this drug prescribed?
Celexa is used to treat depression. Citalopram is in a class of antidepressants called selective serotonin reuptake inhibitors (SSRIs). It is thought to work by increasing the amount of serotonin, a natural substance in the brain that helps maintain mental balance. Citalopram is also sometimes used to treat eating disorders, alcoholism, panic disorder (condition that causes sudden attacks of extreme fear with no apparent cause), premenstrual dysphoric disorder (a group of physical and emotional symptoms that occur before the menstrual period each month), and social phobia (excessive anxiety about interacting with others). Talk to your doctor about the possible risks of using this medication for your condition.
Reasons to buy Celexa:
How should this medicine be used?
Celexa comes as a tablet and a solution (liquid) to take by mouth. It is usually taken once a day, in the morning or in the evening, with or without food. Take citalopram at around the same time every day. 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.
Your doctor may start you on a low dose of citalopram and gradually increase your dose, not more often than once a week.
It may take 1 to 4 weeks before you notice the full benefit of citalopram. Continue to take citalopram even if you feel well. If you suddenly stop taking citalopram, you may experience withdrawal symptoms such as mood changes, irritability, agitation, dizziness, numbness, tingling or electric shock-like sensations in the hands or feet, anxiety, confusion, headache, tiredness, nausea, sweating, shaking, and difficulty falling asleep or staying asleep. Do not stop taking citalopram without talking to your doctor. Your doctor will probably decrease your dose gradually.

There are several Celexa warnings and precautions to be aware of before taking this drug. For example, Celexa may not be safe to take during pregnancy. Also, people who take both Celexa and nonsteroidal anti-inflammatory drugs (NSAIDs) are at a higher risk for gastrointestinal bleeding. Before taking Celexa, be sure to tell your doctor if you have bipolar disorder, liver disease, or a history of suicide attempts.
