Treatment of Obsessive-Compulsive Disorder (OCD)

OCD is characterized by intrusive obsessional thoughts and compulsive rituals performed to reduce anxiety. It affects 2-3% of the population; exposure and response prevention (ERP) therapy combined with SSRIs is the gold standard treatment.

Managing Obsessive-Compulsive Disorder (OCD) effectively requires a combination of medical treatment, lifestyle modification, and regular monitoring. With a structured management plan, most people with Obsessive-Compulsive Disorder (OCD) can maintain a good quality of life and prevent serious complications.

First-Line Treatment Principles

✓Establish accurate diagnosis with standardised rating scales (PHQ-9, GAD-7, YMRS, PANSS)
✓SSRIs or SNRIs as first-line for depression, anxiety disorders, OCD, and PTSD
✓Lithium or valproate as mood stabilisers in bipolar disorder
✓Antipsychotics for schizophrenia; clozapine for treatment-resistant cases
✓Psychotherapy (CBT, IPT, DBT) as first-line or adjunct in most psychiatric conditions

Medications Used in Obsessive-Compulsive Disorder (OCD)

Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) used as a first-line treatment for depression, anxiety disorders, OCD, and PTSD.

SertralineSSRI

Sertraline is a selective serotonin reuptake inhibitor (SSRI) used as a first-line treatment for depression, anxiety disorders, OCD, and PTSD.

ParoxetineSSRI

Paroxetine is a selective serotonin reuptake inhibitor (SSRI) used as a first-line treatment for depression, anxiety disorders, OCD, and PTSD.

CitalopramSSRI

Citalopram is a selective serotonin reuptake inhibitor (SSRI) used as a first-line treatment for depression, anxiety disorders, OCD, and PTSD.

EscitalopramSSRI

Non-Pharmacological Management

•Psychotherapy: CBT for depression, anxiety, OCD, PTSD; DBT for borderline PD; ACT for chronic conditions
•Regular aerobic exercise: 150 min/week — reduces depression scores comparably to antidepressants in mild-moderate MDD
•Sleep hygiene: critical in depression, bipolar, and anxiety — circadian rhythm stabilisation
•Alcohol and substance avoidance: major driver of psychiatric deterioration
•Social support and peer support groups
•Mindfulness-based cognitive therapy (MBCT) to prevent MDD relapse
•Crisis planning: safety plan, emergency contacts, medication access

Treatment Goals

🎯Remission: PHQ-9 <5, GAD-7 <5; minimal/no symptoms for ≥2 months

🎯Functional recovery: return to work/study and social functioning

🎯Relapse prevention: maintenance therapy in recurrent disorders

🎯Quality of life improvement — patient-reported outcomes

🎯Safety: minimise suicide risk; substance use recovery

Monitoring Parameters

◆Validated symptom scales: PHQ-9 (depression), GAD-7 (anxiety), MADRS, YMRS — at each visit
◆Side effect monitoring: weight, metabolic parameters (antipsychotics), thyroid (lithium), LFTs (valproate)
◆Lithium levels: 5–7 days after initiation/dose change; then every 3–6 months when stable (target 0.6–1.0 mmol/L)
◆ECG: QTc monitoring with antipsychotics (ziprasidone, amisulpride, haloperidol)
◆Metabolic syndrome screening: waist circumference, BP, fasting glucose, lipids — annually on antipsychotics
◆AIMS for tardive dyskinesia (antipsychotics) — 6-monthly

Red Flags — When to Escalate

⚠Any of the characteristic symptoms of Obsessive-Compulsive Disorder (OCD) — even mild — in a high-risk individual
⚠Progressive worsening of early warning signs over weeks
⚠Laboratory abnormalities (e.g., blood sugar, inflammatory markers) without full symptoms
⚠Unexplained weight loss, night sweats, or fatigue persisting >2 weeks
⚠Strong family history of Obsessive-Compulsive Disorder (OCD) combined with new relevant symptoms
⚠Sudden worsening of Obsessive-Compulsive Disorder (OCD) symptoms despite established treatment

Escalation Criteria

→Active suicidal ideation with intent/plan → emergency psychiatric assessment; hospitalisation if risk confirmed
→Psychotic relapse in schizophrenia → urgent psychiatric review; consider clozapine if ≥2 antipsychotic failures
→Bipolar manic episode → inpatient; optimise mood stabiliser; antipsychotic augmentation
→Treatment-resistant depression (≥2 failed SSRI trials) → augmentation (lithium, aripiprazole), referral, TMS/ECT consideration

Special Populations

Pregnancy: SSRIs (sertraline preferred) generally acceptable; avoid paroxetine (cardiac defects); valproate contraindicated; specialist review

Elderly: lower starting doses; risk of QTc prolongation; avoid TCA (anticholinergic); falls risk with sedating agents

Adolescents: black-box warning — monitor for suicidality in first weeks of antidepressant treatment

Intellectual disability: behavioural approaches first-line; medication at lower doses; monitor for hidden side effects
