Doses of less than 30 micrograms a day generally have been unsuccessful (1). Suboptimal responses have been reported on doses of up to 100 micrograms a day (1, 2). Better results have followed administration of still larger amounts—as much as 1,000 micrograms a day (3). Other schedules have been used, for example, 1,000 micrograms (1 milligram) once a week (3-7). In Table 1, we have...References1.
