Key takeaways:
Lunesta (eszopiclone) is a prescription sleeping pill that can help you fall and stay asleep. It’s a controlled substance, so it should be taken for the shortest amount of time possible.
The recommended starting Lunesta dosage is 1 mg by mouth, taken on an empty stomach right before bedtime. The maximum dosage is 3 mg at bedtime. Doses greater than 1 mg can increase the risk of experiencing impairment the next day.
If you think you’re taking too much Lunesta, or if you want to make sure your dose is safe, talk to your prescriber.
What’s the safest starting Lunesta (eszopiclone) dosage? It depends.
In 2014, the FDA announced that Lunesta’s manufacturer must lower the recommended starting dose. This is because Lunesta’s starting dose at the time — and higher doses of it — have been shown to affect alertness the next day in activities such as driving. This change resembles past recommendations to lower the bedtime dose for zolpidem (Ambien, Ambien CR, Edluar).
But how much Lunesta should you take? And what time should you take it? Here’s what you should know about Lunesta dosages.
Lunesta is used to treat insomnia (trouble sleeping) in adults. The recommended starting dosage of Lunesta is 1 mg by mouth, taken on an empty stomach right before bedtime. Take Lunesta only if you’re planning to stay in bed for at least 7 to 8 hours after taking it.
If needed, your prescriber may increase your Lunesta dosage up to a maximum of 3 mg at bedtime. But keep in mind that doses higher than 1 mg increase the risk of feeling impaired the next day, which can affect your ability to drive.
Keep in mind: Lunesta is a controlled substance, meaning that it has a risk of dependence and misuse. Because of this, it’s recommended to take the lowest effective dose for the shortest amount of time possible.
Certain people may be more sensitive to Lunesta’s effects, such as older adults. In these cases, a lower dose may be recommended. Lower doses are also advised for people with liver problems and those taking certain medications.
People ages 65 and older may be more likely to experience side effects from Lunesta. Because of this, experts recommend that people in this age group avoid Lunesta. But if your prescriber believes it’s appropriate for you, the recommended maximum Lunesta dosage is 2 mg for older adults.
Like many other medications, Lunesta is broken down in the liver. If you have liver problems, this can lead to higher Lunesta levels in the body. It’s recommended that people with severe liver problems take no more than 2 mg of Lunesta at night.
Some medications can interfere with how Lunesta is broken down in the liver, leading to higher levels and increased side effects. Similar to the adjustments above, the maximum recommended Lunesta dose is 2 mg if you’re taking one of these medications. Examples include:
Antibiotics, such as clarithromycin
Antifungals, such as ketoconazole
Some antiviral medications, such as Paxlovid (nirmatrelvir / ritonavir)
Antidepressants, such as nefazodone

Lunesta can interact with other medications and substances, including those that make you drowsy. Make sure your healthcare team has your current medication list to check for potential interactions. If needed, they can come up with a plan to manage them.
Some people are instructed to take Lunesta every night, while others take it only as needed. Here are some tips for what to do if you miss your Lunesta dose, depending on how you take it.
If you take Lunesta as needed: If you don’t take Lunesta on a regular schedule, skip the dose you missed. Take Lunesta the next time you think you’ll need it to help you sleep.
If you take Lunesta every night: If you forget to take a dose before going to bed, wait until the next evening to take your regularly scheduled dose. Avoid taking an extra or double dose to make up for a missed dose.
But if you wake up at night and still have at least 7 to 8 hours that you’re planning to sleep, you may be able to take the dose you missed. Your prescriber can provide specific recommendations for what to do if this happens.
Taking too much Lunesta is likely to worsen its side effects. You may experience worse drowsiness and extra grogginess or sleepiness the next day. In severe cases, you could have hallucinations, slowed breathing, and coma. If you take Lunesta with other medications that have similar effects, it’s even more risky.
If you or a loved one has taken too much Lunesta, contact a healthcare professional, or Poison Control at 1-800-222-1222, immediately. If the symptoms are severe or life-threatening, call 911 or go to the ER.
Lunesta should be taken immediately before bedtime, only once per day. If you take it too early, you might feel too sleepy before you’re ready to go to bed. Before taking a dose, make sure you have at least 7 to 8 hours before you need to get up the next morning.
Lunesta starts working quickly, which is why you should take it right before you go to bed. The medication will reach maximum levels in the body within an hour of taking it. Lunesta may take longer to work if you take it with or shortly after a high-fat meal. So it’s best to take it on an empty stomach.
During clinical trials, the most commonly reported Lunesta side effects were headaches, drowsiness, and unpleasant taste. Other common side effects included dry mouth, nausea, and infections.
