Mood changes on Lunesta: what to expect
Mood changes — anxiety, low mood, irritability, emotional blunting — are an under-recognised but important side-effect category for many medications. Whether Lunesta (Eszopiclone) at 1mg, 2mg, 3mg causes mood changes depends on Eszopiclone and the indication. This page focuses on the practical pattern, what is normal and what calls for review.
Documented mood effects of Lunesta
For some medications in Sleep Aids and Hypnotics, mood changes are part of the central indication. For others, mood changes are listed in the prescribing information for Eszopiclone as side effects in a small subset of users, sometimes appearing in the first weeks of therapy and resolving spontaneously. Eszopiclone is a positive allosteric modulator of the GABA-A receptor at a site close to the benzodiazepine binding site.
When mood changes need review
Mild irritability or transient low mood in the first weeks on Lunesta at 1mg, 2mg, 3mg is common and often improves. Persistent low mood, new anxiety that interferes with daily life, suicidal thoughts, or any sudden severe mood change warrants prompt review with the prescriber. According to current guidelines, suicidal ideation while starting any new medication should be treated as urgent.
