OverviewDosageSide EffectsInteractionsHalf-Life

Physicians most commonly prescribe Lexapro (escitalopram) to treat anxiety and depression, particularly related to the mental health disorders, Generalized Anxiety Disorder (GAD) and Major Depressive Disorder (MDD).

In some cases, however, physicians can prescribe Lexapro to treat Obsessive Compulsive Disorder (OCD), an anxiety disorder characterized by prolonged, excessive thoughts that result in compulsive behaviors.

Dosage

Lexapro doses for OCD may vary, depending on the individual’s symptoms, health history and sensitivity to side effects.

The FDA does not specifically outline exact Lexapro dosage for OCD cases, so it is critical to talk with your doctor about taking Lexapro for OCD, including any prior medications you have taken for symptoms. Your doctor may recommend seeing an OCD specialist or a psychiatrist to best determine if Lexapro is right for you.

Is Lexapro used to treat OCD?

One 2014 study concluded that selective serotonin reuptake inhibitors (SSRIs) are more effective in treating OCD in high doses, which typically exceed the doses recommended to treat Major Depressive Disorder (MDD). The study noted a 40mg dose of escitalopram (Lexapro) is often “needed” to treat OCD symptoms. This is different from doses for MDD, where higher doses, the study states, often result in higher side effects.

The same study also found that OCD patients treated with Lexapro—or a different SSRI—may take longer to adjust to the medicine, as well as require longer treatment with it.
