Starting LEXAPRO / Dosage Issues
continued from page 1
Below are the answers to frequently asked questions about the SSRI antidepressant
LEXAPRO (escitalopram oxalate). The answers are provided by HealthyPlace.com Medical
Director, Harry Croft, MD, a board-certified psychiatrist.
As you are reading these answers, please
remember these are "general answers" and not meant to apply to your
specific situation or condition. Keep in mind that editorial content is never a
substitute for a visit to a health care professional.
Q: When you first start LEXAPRO, what should
that feel like—physically and emotionally?
When first taking LEXAPRO, a patient might feel
little change, unless there are some initial side effects (which generally
disappear after 7 to 14 days). For most patients, it takes at least a week or
two before they feel any improvement. Full antidepressant effect may take 4
to 6 weeks.
In general, emotional improvement is gradual,
and realized by looking back over the past several days and noting "you know,
I am starting to feel less hopeless, despondent, and depressed." It is also
common to begin to have some "good" days only to have them followed by some
"not so good" ones. Patients should not feel discouraged by the "blue" days,
but rather encouraged by the "good ones", as they indicate that recovery
is beginning.
In clinical trials, LEXAPRO was shown to be well
tolerated by most people with many of the side effects disappearing in the first
few weeks.
The most common adverse events reported with
LEXAPRO vs placebo (approximately 5% or greater and approximately 2X placebo)
were nausea, insomnia, ejaculation disorder, somnolence, increased sweating,
fatigue, decreased libido, and anorgasmia. LEXAPRO is contraindicated in
patients taking monoamine oxidase inhibitors (MAOIs) or in patients with a
hypersensitivity to escitalopram oxalate or any of the ingredients in LEXAPRO.
Lexapro is contraindicated in patients taking pimozide (see
DRUG INTERACTIONS - Pimozide and Celexa). As with other SSRIs, caution is indicated in the
coadministration of tricyclic antidepressants (TCAs) with LEXAPRO. As with
other psychotropic drugs that interfere with serotonin reuptake, patients
should be cautioned regarding the risk of bleeding associated with the
concomitant use of LEXAPRO with NSAIDs, aspirin, or other drugs that affect
coagulation. Patients with major depressive disorder, both adult and pediatric,
may experience worsening of their depression and/or the emergence of suicidal
ideation and behavior (suicidality), whether or not they are taking antidepressant
medications, and this risk may persist until significant remission occurs.
Although no causal role for antidepressants in inducing such behaviors has been
established, patients being treated with antidepressants should be observed
closely for clinical worsening and suicidality, especially at the beginning of
a course of drug therapy, or at the time of dose changes, either increases or decreases.

side effects section.
Q: What if you miss a dose of Lexapro? How will that
make you feel and what should you do about it?
A: For most patients, one missed dose
of LEXAPRO doesn’t cause many symptoms. If it is the same day when you realize
you have missed a dose, take it then. If it is the next day, take the usual dose
for that day. In general, it is not necessary to "catch up" by taking extra doses
to make up for the one missed. Try not to miss doses of medication. Take them
daily and regularly for as long as your doctor prescribes. This may be for
several months after recovery from your depressive symptoms. This is to help
keep your depression from coming back.
One other word of caution: Always consult
with your physician before discontinuing your antidepressant medication.
Q: If you are switching from another antidepressant
to LEXAPRO or vice versa, what should you keep in mind? What is entailed in the
switchover? Can you switch from Celexa to LEXAPRO without a waiting period?
A: Although several antidepressants work by
increasing the effectiveness of the brain neurotransmitter serotonin, these
medications do not look alike structurally. Therefore, one SSRI may work in a
single patient, whereas another SSRI (working on the same brain "juice," serotonin)
may not work for that patient, and thus a switch may be necessary. Studies show
that up to 50% of patients not responding to one SSRI may respond to another.
In general, patients can be switched from one SSRI
to another without a waiting period in-between. This is no different for patients
on Celexa. However, due to serotonin discontinuation symptoms, it is probably best
to taper off one SSRI instead of just stopping it abruptly. I generally start patients
on LEXAPRO while I taper off the other antidepressant, but other physicians may suggest
tapering off the first, before starting the second. There is very little danger in
overlapping the drugs for a short time, however.
