USOfficial regulatory label· Adverse reactions· revised May 7, 2026[1]
4) ] Most common adverse reactions (≥3% and more common than with placebo) are: somnolence, dizziness, fatigue, nausea, and exacerbated insomnia. 1) To report SUSPECTED ADVERSE REACTIONS, contact Innogenix, LLC. gov/medwatch. 1 Clinical Trials Experience Adverse Reactions Resulting in Discontinuation of Treatment The data described in this section reflect exposure to Ramelteon Tablets in 5373 subjects, including 722 exposed for six months or longer, and 448 subjects for one year.
Six percent of the 5373 individual subjects exposed to Ramelteon Tablets 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 Ramelteon Tablets were somnolence, dizziness, nausea, fatigue, headache, and insomnia; all of which occurred in 1% of the patients or less.
Ramelteon Tablets 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 Ramelteon Tablets. 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. Table 1.

5 WARNINGS AND PRECAUTIONS Severe anaphylactic/anaphylactoid reactions: Angioedema and anaphylaxis have been reported. Do not rechallenge if such reactions occur. 1 ) Need to evaluate for comorbid diagnoses: Reevaluate if insomnia persists after 7 to 10 days of treatment.
2 ) Abnormal thinking, behavioral changes, complex behaviors: May include “sleep-driving” and hallucinations. Immediately evaluate any new onset behavioral changes. 3 ) Depression: Worsening of depression or suicidal thinking may occur.
3 ) CNS effects: Potential impairment of activities requiring complete mental alertness such as operating machinery or driving a motor vehicle, after ingesting the drug. 4 ) Reproductive effects: Include decreased testosterone and increased prolactin levels.
Effect on reproductive axis in developing humans is unknown. 5 ) Patients with severe sleep apnea: Ramelteon Tablets is not recommended for use in this population. 1 Severe Anaphylactic and Anaphylactoid Reactions Rare cases of angioedema involving the tongue, glottis or larynx have been reported in patients after taking the first or subsequent doses of Ramelteon Tablets.
Some patients have had additional symptoms such as dyspnea, throat closing, or nausea and vomiting that suggest anaphylaxis. Some patients have required medical therapy in the emergency department. If angioedema involves the tongue, glottis or larynx, airway obstruction may occur and be fatal.
Patients who develop angioedema after treatment with Ramelteon Tablets should not be rechallenged with the drug. 2 Need to Evaluate for Comorbid Diagnoses Since sleep disturbances may be the presenting manifestation of a physical and/or psychiatric disorder, symptomatic treatment of insomnia should be initiated only after a careful evaluation of the patient.
The failure of insomnia to remit after 7 to 10 days of treatment may indicate the presence of a primary psychiatric and/or medical illness that should be evaluated . Worsening of insomnia, or the emergence of new cognitive or behavioral abnormalities, may be the result of an unrecognized underlying psychiatric or physical disorder and requires further evaluation of the patient.
