Antidepressant Medicines Used to Treat OCD
Selective serotonin reuptake inhibitors (SSRIs)
How It Works
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.
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.
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.
All medicines have side effects. But many people don't feel the side effects, or they are able to deal with them. Ask your pharmacist about the side effects of each medicine you take. Side effects are also listed in the information that comes with your medicine.

The U.S. Food and Drug Administration (FDA) has issued an advisory on antidepressant medicines and the risk of suicide. Talk to your doctor about these possible side effects and the warning signs of suicide.
What To Think About
Never suddenly stop taking antidepressants. The use of any antidepressant should be tapered off slowly and only under the supervision of a doctor. Abruptly stopping antidepressant medicine can cause negative side effects or a relapse into a depressive episode or anxiety disorder.
If other mental health problems (such as depression) are present along with OCD, other medicines (such as a mood stabilizer or an antianxiety or antipsychotic medicine) also may be needed to effectively treat the combined disorders.
SSRIs can be safer than tricyclic or tetracyclic antidepressants, because they don't cause death if taken in large quantities (overdose). SSRIs usually are well tolerated and effective. SSRIs also may be safer for older adults, because the side effects are more tolerable.
People with liver disease usually need lower doses of SSRIs.
Studies have found that 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.
SSRIs make bleeding more likely in the upper gastrointestinal tract (stomach and esophagus). Taking SSRIs with NSAIDs (such as Aleve or Advil) makes bleeding even more likely. Taking medicines that control acid in the stomach may help.1
Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
Advice for women
Women who take an SSRI during pregnancy have a slightly higher chance of having a baby with birth defects. If you are pregnant, you and your doctor must weigh the risks of taking an SSRI against the risks of not treating your anxiety disorder.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
