Clinical Trials Experience
Adverse Reactions Resulting in Discontinuation of Treatment
The data described in this section reflect exposure to ROZEREM (ramelteon) in 5373 subjects, including 722 exposed for 6 months or longer, and 448 subjects for one year.
Six percent of the 5373 individual subjects exposed to ROZEREM (ramelteon) in clinical studies discontinued treatment owing to an adverse event, compared with 2% of the 2279 subjects receiving placebo. The most frequent adverse events leading to discontinuation in subjects receiving ROZEREM (ramelteon) were somnolence, dizziness, nausea, fatigue, headache, and insomnia; all of which occurred in 1% of the patients or less.
ROZEREM (ramelteon) Most Commonly Observed Adverse Events
Table 1 displays the incidence of adverse events reported by the 2861 patients with chronic insomnia who participated in placebo-controlled trials of ROZEREM (ramelteon) .
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in clinical trials of other drugs, and may not reflect the rates observed in practice. The adverse reaction information from clinical trials does, however, provide a basis for identifying the adverse events that appear to be related to drug use and for approximating rates.
