How It Works
Antidepressants improve mood by affecting
the levels of a chemical messenger in the brain (neurotransmitter) called serotonin.
Why It Is Used
Antidepressants are used to relieve
obsessive thoughts and subsequent compulsive behaviors in those who have
obsessive-compulsive disorder (OCD).
How Well It Works
Research shows that certain
antidepressants improve symptoms of OCD and help balance brain chemicals.

FDA Advisories. The U.S. Food and Drug Administration (FDA)
has issued:
- An
advisory on antidepressant medicines and the risk of
suicide. The FDA does not recommend that people stop using these medicines.
Instead, a person taking antidepressants should be watched for
warning signs of suicide. This is especially important
at the beginning of treatment or when doses are changed.
- A
warning about the antidepressants Paxil or Paxil CR
and birth defects. Taking these medicines in the first 12 weeks of pregnancy
may increase your chance of having a baby with a birth defect.
What To Think About
For children and adolescents with
OCD, treatment combining
cognitive-behavioral therapy with antidepressants
(SSRIs), such as sertraline, works better than only taking medicine.
Cognitive-behavioral therapy alone also works well, but it works better if it
is combined with medicine.1
You may
start to feel better within 1 to 3 weeks of taking antidepressant medicine. But
it can take as many as 12 weeks to see more improvement. If you have questions
or concerns about your medicines, or if you do not notice any improvement by 3
weeks, talk to your doctor. It is possible that one of the medicines will work
better for you than another. You may have to try several medicines before you
find the right one.
If other mental health problems (such as
depression) are present along with OCD, additional medicines (such as a mood
stabilizer or an antianxiety or antipsychotic medicine) also may be needed to
effectively treat the combined disorders.
Studies have found daily
use of SSRIs may increase the risk of bone fracture in adults over age 50. Talk
to your doctor about this risk before taking an SSRI.
If you are
pregnant or nursing, you and your doctor need to decide whether taking an SSRI
is appropriate.
