The dosage should be initiated at a low level and increased gradually, noting the clinical response and any evidence of intolerance. Occurrence of drowsiness may require the administration of a major portion of the daily dose at bedtime or a reduction of dosage. DESYREL should be taken shortly after a meal or light snack. Symptomatic relief may be seen during the first week, with optimal antidepressant effects typically evident within two weeks. Twenty-five percent of those who respond to DESYREL require more than two weeks (up to four weeks) of drug administration.
Usual Adult Dosage
An initial dose of 150 mg/day in divided doses is suggested. The dose may be increased by 50 mg/day every three to four days. The maximum dose for outpatients usually should not exceed 400 mg/day in divided doses. Inpatients (ie, more severely depressed patients) may be given up to but not in excess of 600 mg/day in divided doses.
Dosage during prolonged maintenance therapy should be kept at the lowest effective level. Once an adequate response has been achieved, dosage may be gradually reduced, with subsequent adjustment depending on therapeutic response.
Although there has been no systematic evaluation of the efficacy of DESYREL beyond six weeks, it is generally recommended that a course of antidepressant drug treatment should be continued for several months.
