Lunesta is the brand name for eszopiclone, a prescription sleep medication FDA-approved for the treatment of insomnia in adults. It was approved by the FDA on December 15, 2004, and is one of the few approved hypnotics with clinical evidence supporting use for up to 6 months.
Lunesta belongs to the class of medications called non-benzodiazepine sedative-hypnotics, often called Z-drugs. It is chemically distinct from benzodiazepines but works at the same GABA-A receptor complex. Lunesta addresses both difficulty falling asleep and difficulty staying asleep, making it effective for a wide range of insomnia presentations.
Generic eszopiclone is widely available from multiple manufacturers including Aurobindo Pharma, Dr. Reddy's Laboratories, and Camber Pharmaceuticals. In 2020, eszopiclone was the 232nd most commonly prescribed medication in the United States with more than 1 million prescriptions.

Lunesta (eszopiclone) works by acting as a positive allosteric modulator of GABA-A receptors — the brain's main inhibitory receptor system. GABA (gamma-aminobutyric acid) is the brain's primary "braking" neurotransmitter. By binding to GABA-A receptors alongside GABA and amplifying its effect, eszopiclone slows down neural activity and promotes sleep.
Unlike benzodiazepines, which broadly activate all GABA-A receptor subtypes, eszopiclone binds more selectively to subtypes primarily involved in sleep and sedation. Eszopiclone takes effect within approximately 30 minutes of ingestion, with peak blood levels reached in about 1 hour. Its half-life of approximately 6 hours provides nightlong sleep coverage.
Eszopiclone is primarily metabolized by the liver enzymes CYP3A4 and CYP2E1, which is why it has interactions with many medications that affect these enzymes, including certain antifungals, antibiotics, and antivirals.
1 mg — tablet
Starting dose for most adults and all elderly patients; FDA recommended starting dose as of 2014
2 mg — tablet
Intermediate dose; maximum dose for elderly patients (65+) and patients with severe hepatic impairment
3 mg — tablet
Maximum adult dose; most effective for sleep maintenance but highest risk of next-day impairment
As of 2026, Lunesta (eszopiclone) is not on the FDA's official drug shortage list and is generally widely available. Multiple generic manufacturers supply the U.S. market, which provides good supply resilience. medfinder rates eszopiclone's findability at 88/100 — meaning it is widely stocked with only minor, localized gaps.
However, patients do occasionally encounter difficulty finding specific doses (1 mg, 2 mg, or 3 mg) at particular pharmacies. This is more common with brand-name Lunesta, which is stocked far less widely than generic eszopiclone. As a Schedule IV controlled substance, pharmacies have ordering limits that create additional friction compared to non-controlled medications.
When your pharmacy is out of eszopiclone, medfinder calls pharmacies near you to check which ones have your specific dose in stock and texts you the results — saving you hours of phone calls.
Because Lunesta (eszopiclone) is a DEA Schedule IV controlled substance, it can only be prescribed by licensed healthcare providers who are registered with the DEA to prescribe controlled substances. This includes the vast majority of licensed prescribers.
Providers who commonly prescribe Lunesta:
Primary care physicians (family medicine, internal medicine)
Psychiatrists
Sleep medicine specialists
Neurologists (particularly sleep-focused)
Nurse practitioners (NPs) — in most states with full or restricted prescriptive authority for Schedule IV
Physician assistants (PAs) — in most states
Telehealth prescribing of eszopiclone is available through several platforms that specialize in sleep medicine or primary care. Patients should confirm the platform can prescribe Schedule IV controlled substances in their state. An appropriate prescriber-patient relationship must be established before eszopiclone can be prescribed.
Yes. Lunesta (eszopiclone) is classified by the DEA as a Schedule IV controlled substance under the Controlled Substances Act. This means it has recognized medical use but also potential for abuse, dependence, and addiction.
Practical implications for patients:
A new prescription from your doctor is required for each fill — unlike non-controlled medications, you cannot simply phone in a refill
Prescription transfers between pharmacies are restricted — most states allow only one transfer of a Schedule IV prescription
Early refills are typically not allowed until within a few days of running out
Sharing or selling Lunesta is illegal, regardless of reason
Long-term users may develop physical dependence, and abrupt discontinuation can cause withdrawal symptoms including rebound insomnia and anxiety. Always work with your doctor before stopping Lunesta after extended use.
Lunesta carries an FDA boxed warning — the most serious type — for complex sleep behaviors. This includes sleepwalking, sleep-driving, and other activities performed while not fully awake. Stop the medication and contact your doctor immediately if any such behavior occurs.
Common side effects include:
Unpleasant, bitter, or metallic taste in the mouth (most distinctive Lunesta side effect)
Headache
Next-day drowsiness or "hangover" feeling (especially at 3 mg dose)
Dry mouth
Dizziness
Nausea
Serious side effects requiring immediate medical attention:
Complex sleep behaviors (sleepwalking, sleep-driving) — boxed warning
Severe allergic reaction (angioedema — swelling of face, lips, tongue, throat)
Hallucinations or abnormal thoughts or behavior
Worsening depression or suicidal thoughts

Zolpidem (Ambien)
Closest therapeutic equivalent; also a Z-drug (Schedule IV); faster onset but shorter duration than Lunesta; available as IR and CR (extended-release) forms
Ramelteon (Rozerem)
Melatonin receptor agonist; not a controlled substance; no dependence risk; better for sleep-onset than sleep maintenance insomnia
Trazodone
Antidepressant used off-label for insomnia; not controlled; lower dependence risk; may be preferred for patients with co-occurring depression or anxiety
Suvorexant (Belsomra)
Orexin receptor antagonist; Schedule IV; different mechanism of action (blocks wakefulness signals vs. enhancing sleep signals); newer class of sleep medications

Alcohol
majorAdditive CNS depression; significantly increases risk of complex sleep behaviors, next-day impairment, and overdose. Completely avoid while taking eszopiclone.
Opioids (oxycodone, hydrocodone, morphine)
majorCombined CNS depression increases risk of respiratory depression, coma, and death. Requires close medical supervision if combined.
CYP3A4 inhibitors (ketoconazole, clarithromycin, Paxlovid/ritonavir)
majorReduce breakdown of eszopiclone, causing significantly higher blood levels and amplified side effects. Dose reduction required; max starting dose 1 mg.
Benzodiazepines (lorazepam, alprazolam, clonazepam)
moderateAdditive CNS depression; combined use at bedtime not recommended. Risk of excessive sedation and complex sleep behaviors.
Rifampin (CYP3A4 inducer)
moderateSignificantly reduces eszopiclone blood levels, potentially reducing effectiveness. May require dose adjustment.
Olanzapine
moderatePharmacodynamic interaction causing decreased psychomotor performance (decreased DSST scores). Use with caution.
High-fat/heavy meals
minorSlows absorption and delays onset of sleep effect. Take on relatively empty stomach at bedtime for best effect.
Lunesta (eszopiclone) is an effective, FDA-approved treatment for chronic insomnia backed by clinical evidence supporting use up to 6 months. It is particularly effective for patients who struggle with both falling asleep and staying asleep throughout the night. Generic eszopiclone provides the same clinical benefit as brand-name Lunesta at a fraction of the cost — as little as $7-$11 per month with discount programs.
As a Schedule IV controlled substance, Lunesta requires careful adherence to safe-use guidelines: always take it immediately before a full 7-8 hours of sleep, never combine with alcohol or other CNS depressants, use the lowest effective dose, and monitor for complex sleep behaviors. Long-term users should periodically reassess whether continued treatment is needed.
If you are prescribed eszopiclone and encounter difficulty finding it at your local pharmacy, medfinder calls pharmacies near you to find which ones have your specific dose in stock and texts you the results — so you can get your medication without making dozens of phone calls.
