Celexa

Celexa is a prescription drug that is used to treat depression in adults. The drug works by balancing the levels of a certain chemical in the brain (serotonin). In addition to reducing the symptoms of depression, Celexa has also been shown to reduce the chances of a relapse. The medication comes in both tablet and liquid form, and is generally taken once a day. Possible side effects include nausea, dry mouth, sweating, and insomnia.

What Is Celexa?

Celexa® (citalopram hydrobromide) is a prescription medicine used for the treatment of depression (also known as major depression or clinical depression).
 
(Click Celexa Uses for more information on what it is used for, including possible off-label uses.)
 

Who Makes Celexa?

Celexa is manufactured by Forest Pharmaceuticals. Generic Celexa is made by several manufacturers.
 

How Does It Work?

Celexa is part of a class of drugs called selective serotonin reuptake inhibitors, or
 SSRIs for short. SSRIs, such as Celexa, act on a specific chemical within the brain known as serotonin. Serotonin is one of several chemicals used to send messages from one nerve cell to another.
 
As a message travels down a nerve, it causes the end of the cell to release serotonin. The serotonin enters the gap between the first nerve cell and the one next to it. When enough serotonin reaches the second nerve cell, it activates receptors on the cell and the message continues on its way. The first cell then quickly absorbs any serotonin that remains in the gap between cells. This is called "reuptake."
 
Normally, this process works without any problems. When the levels of serotonin become unbalanced, however, it can cause a variety of conditions, including depression. Celexa helps to block the reuptake of serotonin so more serotonin remains in the space between the brain's nerve cells. This gives the serotonin a better chance of activating the receptors on the next nerve cell.
 

How Effective Is It?

Studies have shown Celexa to be effective for depression treatment in adults. People who took it showed more improvement in depression symptoms compared to people not taking the medicine. Also, long-term studies have shown that fewer people taking it relapse (have their depression come back) than people not taking it.
 

When and How to Take Celexa

Some general considerations for when and how to take the medication include:
 
  • Celexa comes in tablet form and also in liquid form. It is taken by mouth usually once a day.
     
  • If it makes you drowsy, try taking it before bedtime. If it causes insomnia for you, try taking it in the morning.
     
  • You can take the medication with or without food. If it bothers your stomach, try taking it with food.
     
  • It should be taken at the same time each day to maintain an even level of the drug in your blood.
     
  • For the medicine to work properly, it must be taken as prescribed. It will not work if you stop taking it.
     

Dosing

The dosage that your healthcare provider recommends will vary depending on a number of factors, including:
 
  • Your age
  • Other medical conditions you may have
  • Other medications you may currently be taking.
     
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.

Side Effects

As with any medicine, there are possible side effects. However, not everyone who takes the medication will experience side effects. In fact, most people tolerate it well. When side effects do occur, in most cases they are minor and either require no treatment or can easily be treated by you or your healthcare provider. Serious side effects are less common.

Alternatives to Celexa

Depression, even in its most severe form, is highly treatable. As with many illnesses, getting depression treatment early is more effective and reduces the chance of recurrence.
 
The most common forms of treatment for depression are medication (antidepressants) and psychotherapy ("talk therapy"). In some cases of severe depression, healthcare providers may recommend electroconvulsive therapy (ECT). Some people may also try complementary or alternative treatments for depression (see Natural Remedies for Depression).
 
For most people, Celexa is quite effective at treating depression. It is also generally well-tolerated. However, side effects can occur, or the medicine may not work as well as needed. In these cases, your healthcare provider may recommend an alternative. Some example of substitute depression medications include:
