Boxed warning

Suicidality and Antidepressant Drugs

Antidepressants increased the risk compared to placebo of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults in short-term studies of major depressive disorder (MDD) and other psychiatric disorders. Anyone considering the use of clomipramine hydrochloride or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. Patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. Clomipramine hydrochloride is not approved for use in pediatric patients except for patients with obsessive compulsive disorder (OCD) (see WARNINGS, Clinical Worsening and Suicide Risk; PRECAUTIONS, Information for Patients; and PRECAUTIONS, Pediatric Use).

Key facts

Clomipramine is a tricyclic antidepressant. Per this US label (capsules), it is used to treat obsessions and compulsions in obsessive-compulsive disorder (OCD).

What it is used for

  • Treatment of obsessions and compulsions in OCD that cause marked distress, are time-consuming, or significantly interfere with social or occupational functioning
  • In children and adolescents, approved only for OCD

Dosing

  • Adults: start 25 mg daily, increased as tolerated to approximately 100 mg during the first 2 weeks; then gradually up to a maximum of 250 mg daily
  • Children and adolescents: start 25 mg daily; during the first 2 weeks up to 3 mg/kg or 100 mg, whichever is smaller; thereafter up to 3 mg/kg or 200 mg, whichever is smaller
  • During titration give in divided doses with meals; afterwards the total dose may be given once daily at bedtime
  • Steady state may take 2 to 3 weeks after a dose change; maintain on the lowest effective dose and reassess periodically

Contraindications

  • Hypersensitivity to clomipramine or other tricyclic antidepressants
  • MAOIs for psychiatric disorders concurrently or within 14 days (risk of serotonin syndrome)
  • Starting clomipramine in patients treated with linezolid or intravenous methylene blue
  • Acute recovery period after a myocardial infarction

Important warnings

  • Boxed warning: increased risk of suicidal thinking and behavior in children, adolescents and young adults; monitor closely for clinical worsening
  • Seizure was identified as the most significant risk; dose appears to be a predictor
  • Serotonin syndrome, particularly with other serotonergic drugs
  • Pupillary dilation may trigger angle-closure attacks in patients with anatomically narrow angles

Side effects

  • Commonly observed: dry mouth, constipation, nausea, dyspepsia, anorexia
  • Somnolence, tremor, dizziness, nervousness, myoclonus
  • Changed libido, ejaculatory failure, impotence, micturition disorder
  • Fatigue, sweating, increased appetite, weight gain, visual changes

Interactions

  • MAOIs, linezolid, methylene blue and other serotonergic drugs (e.g. triptans, tramadol, lithium, St. John's Wort): serotonin syndrome
  • Haloperidol increases plasma levels; enzyme inhibitors (e.g. cimetidine, fluoxetine) may increase and inducers (e.g. barbiturates, phenytoin) decrease levels
  • Drugs metabolized by or inhibiting CYP2D6 may raise tricyclic levels
  • May block the effects of guanethidine or clonidine; may increase phenobarbital levels

Pregnancy and breastfeeding

  • Pregnancy: use only if the potential benefit justifies the risk to the fetus; neonatal withdrawal symptoms have been reported
  • Nursing: found in human milk; decide whether to discontinue nursing or the drug
