TREATMENT Combination therapy

In keeping with American Academy of Child and Adolescent Psychiatry guidelines on treating OCD (Table 312), we start M on fluoxetine 10 mg/d. He also begins CBT. Fluoxetine is slowly titrated to 40 mg/d while M engages in learning and utilizing CBT techniques to manage his OCD.

The authors’ observations

The combination of CBT and medication has been suggested as the treatment of choice for moderate and severe OCD.12 The Pediatric OCD Treatment Study, a 5-year, 3-site outcome study designed to compare placebo, sertraline, CBT, and combined CBT and sertraline, concluded that the combined treatment (CBT plus sertraline) was more effective than CBT alone or sertraline alone.13 The effect sizes for the combined treatment, CBT alone, and sertraline alone were 1.4, 0.97, and 0.67, respectively. Remission rates for SSRIs alone are <33%.13,14

SSRIs are the first-line medication for OCD in children, adolescents, and adults (Table 312). Well-designed clinical trials have demonstrated the efficacy and safety of the SSRIs fluoxetine, sertraline, and fluvoxamine (alone or combined with CBT) in children and adolescents with OCD.13 Other SSRIs, such as citalopram, paroxetine, and escitalopram, also have demonstrated efficacy in children and adolescents with OCD, even though the FDA has not yet approved their use in pediatric patients.12 Despite a positive trial of paroxetine in pediatric OCD,12 there have been concerns related to its higher rates of treatment-emergent suicidality,15 lower likelihood of treatment response,16 and its particularly short half-life in pediatric patients.17

Clomipramine is a tricyclic antidepressant with serotonergic properties that is used alone or to boost the effect of an SSRI when there is a partial response. It should be introduced at a low dose in pediatric patients (before age 12) and closely monitored for anticholinergic and cardiac adverse effects. A systemic review and meta-analysis of early treatment responses of SSRIs and clomipramine in pediatric OCD indicated that the greatest benefits occurred early in treatment.18 Clomipramine was associated with a greater measured benefit compared with placebo than SSRIs; there was no evidence of a relationship between SSRI dosing and treatment effect, although data were limited. Adults and children with OCD demonstrated a similar degree and time course of response to SSRIs in OCD.18

Treatment should start with a low dose to reduce the risk of adverse effects with an adequate trial for 10 to 16 weeks at adequate doses. Most experts suggest that treatment should continue for at least 12 months after symptom resolution or stabilization, followed by a very gradual cessation.19
