From the Guidelines
The most effective treatment for Obsessive-Compulsive Disorder (OCD) is a combination of pharmacological and non-pharmacological approaches, with Exposure and Response Prevention (ERP) being the primary non-pharmacological treatment and selective serotonin reuptake inhibitors (SSRIs) being the first-line pharmacological treatment. The treatment of OCD involves both pharmacological and non-pharmacological approaches, often used in combination for optimal results. First-line pharmacological treatment typically includes SSRIs such as fluoxetine (20-80 mg/day), sertraline (50-200 mg/day), paroxetine (20-60 mg/day), fluvoxamine (100-300 mg/day), or escitalopram (10-40 mg/day) 1. These medications should be started at low doses and gradually increased, with treatment continuing for at least 10-12 weeks to assess efficacy, as indicated by recent guidelines 1. Patients should be maintained on effective doses for at least 12 months to prevent relapse. For patients with partial response to SSRIs, augmentation strategies include adding antipsychotics like risperidone (0.5-2 mg/day) or aripiprazole (2.5-15 mg/day), or clomipramine (25-250 mg/day). The primary non-pharmacological treatment is Exposure and Response Prevention (ERP), a specific form of cognitive-behavioral therapy where patients are gradually exposed to anxiety-provoking stimuli while preventing compulsive responses, as supported by recent studies 1. ERP typically involves 12-20 weekly sessions, with homework assignments between sessions. Other helpful approaches include cognitive therapy targeting dysfunctional beliefs, mindfulness-based interventions, and acceptance and commitment therapy. For treatment-resistant cases, more intensive options include intensive outpatient programs, partial hospitalization, residential treatment, or in rare cases, neurosurgical interventions like deep brain stimulation. Family involvement is crucial, as family members often inadvertently accommodate OCD symptoms. The combination of medication and ERP is considered most effective because SSRIs address the neurobiological aspects of OCD by increasing serotonin availability, while ERP helps patients develop new behavioral responses and cognitive patterns that break the obsession-compulsion cycle. Recent studies have also explored the use of computer-assisted self-help interventions without human contact, which may improve access to treatment for patients with OCD, as shown in a recent systematic review and meta-analysis 1. However, the effectiveness and adherence of these interventions require further examination. Key considerations in the treatment of OCD include:
- Patient adherence to between-session homework, such as carrying out ERP exercises in the home environment, which is a robust predictor of good short-term and long-term outcome with CBT 1
- The presence of comorbidities, which can impact treatment efficacy and choice of therapy
- The baseline severity of OCD, which can influence treatment response and the need for more intensive interventions
- The potential for relapse after discontinuing medication, which highlights the importance of maintenance treatment.

From the Research
Pharmacological Treatments
- The primary pharmacological treatments for Obsessive-Compulsive Disorder (OCD) are serotonin reuptake inhibitors, including clomipramine and selective serotonin reuptake inhibitors (SSRIs) such as fluvoxamine, fluoxetine, sertraline, and paroxetine 4, 5, 6, 7.
- These medications have been shown to be effective in reducing symptoms of OCD, with clomipramine and SSRIs being considered first-line agents 5, 6.
- For patients who do not respond to SSRIs, treatment options include switching to another SSRI or clomipramine, or augmentation with an atypical antipsychotic 5, 6, 7.
Non-Pharmacological Treatments
- Cognitive-behavioral therapy (CBT), specifically exposure and response prevention (ERP), is a highly effective non-pharmacological treatment for OCD 4, 6, 7, 8.
- CBT/ERP has been shown to be effective in reducing symptoms of OCD, and can be used in combination with pharmacological treatments for optimal results 7, 8.
- Other non-pharmacological treatments, such as repetitive transcranial magnetic stimulation and deep brain stimulation, may also be effective for refractory OCD, but further research is needed 8.
Treatment Strategies
- Treatment strategies for OCD often involve a combination of pharmacological and non-pharmacological approaches 5, 6, 7, 8.
- The choice of treatment depends on the individual patient's needs and circumstances, and may involve a trial of different medications or therapies to find the most effective approach 4, 5, 6, 7, 8.
- Pharmacogenomics and personalization of therapy may also play a role in reducing treatment resistance and improving outcomes for patients with OCD 7.
