Lexapro is a prescription drug commonly used for treating depression and generalized anxiety disorder. As part of a class of drugs called selective serotonin reuptake inhibitors, it works by helping to block the reuptake of a chemical in the brain called serotonin. The medicine is available in both tablet and liquid form, and is not approved for use in children. Common Lexapro side effects include nausea, insomnia, and headache.
Lexapro is part of a class of drugs called selective serotonin reuptake inhibitors, or
SSRIs for short. SSRIs 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. But when the levels of serotonin become unbalanced, it can cause a variety of conditions, including depression. Lexapro helps to block the reuptake of serotonin so that more 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.
Effects of Lexapro
Several clinical studies have shown Lexapro to be effective at treating depression and generalized anxiety disorder. Also, a long-term study has shown that it can help prevent depression relapse.
When and How to Take It
Suggestions on how and when to take Lexapro include the following:
Lexapro comes in both tablet and liquid form. It is taken by mouth, usually once a day.
If you experience drowsiness, try taking it before bedtime. If it causes insomnia, 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.
Take the drug at the same time each day to maintain an even level in your blood.
For this medicine to work properly, it must be taken as prescribed. It will not work if you stop taking it.
Dosing Information
The dose of Lexapro your healthcare provider recommends will vary, depending on a number of factors, including:
Your age
The medical condition being treated
Other medical conditions you may have
Other medications you may be taking.
As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
As with any medicine, side effects can occur. However, not everyone who takes this medicine will experience side effects. If side effects occur, they are often minor and either require no treatment or can easily be treated by you or your healthcare provider. Serious side effects are less common.
Make sure to tell your healthcare provider about all other medicines you are taking, including prescription and non-prescription medicines, vitamins, and herbal supplements.
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, Lexapro is quite effective at treating depression. It is also generally well tolerated. However, side effects may occur or the medicine may not work as well as needed. In these cases, your healthcare provider may recommend an alternative medication. Some examples of substitute depression medications include:
Other selective serotonin reuptake inhibitors (SSRIs)
Lexapro should be stored at room temperature, away from moisture and heat. Both the tablets and liquid should be kept in airtight containers. Keep this drug -- and all medications -- out of the reach of children.
What Should I Do If I Miss a Dose?
If you do not take your Lexapro as scheduled, take your missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take a double dose.
