Why It Is Used
Antidepressants are used to relieve obsessive thoughts and subsequent compulsive behaviors in those who have obsessive-compulsive disorder (OCD).

FDA Advisories. The US 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 6 to 8 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 go through a trial of 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.
If you are pregnant or nursing, you and your doctor need to decide whether taking an SSRI is appropriate.
