Abrupt or gradual discontinuation of tricyclic antidepressants may precipitate withdrawal symptoms. The most common of these are general somatic or gastrointestinal distress, anxiety and agitation, sleep disturbance, akathisia, parkinsonism, paradoxical behavioral activation and mania. There are very few reports of withdrawal reactions following discontinuation of clomipramine since it has not been in use in the US until recently. 2 patients with withdrawal symptoms following discontinuation of clomipramine are presented. A 45-year-old man had general somatic symptoms, including headache, myalgia, weakness, fatigue (flu-like syndrome) and nervousness and insomnia after clomipramine, 75 mg/d, had been discontinued abruptly. All symptoms disappeared without treatment after 3 days. A 47-year-old woman presented mainly with severe insomnia, anxiety, agitation, jitteriness and tension after discontinuing a low dose of 25 mg/d of clomipramine. Symptoms disappeared after she started self-treatment with 50 mg/d of the drug. It is important to differentiate withdrawal symptoms from relapse of the primary psychiatric disorder.
