  • if you are pregnant, planning to become pregnant, or are breast-feeding

Some MEDICINES MAY INTERACT with Lunesta. Tell your health care provider if you are taking any other medicines, especially any of the following:

  • Lorazepam or rifamycins (eg, rifampin) because they may decrease Lunesta's effectiveness
  • Azole antifungals (eg, itraconazole, ketoconazole), benzodiazepines (eg, alprazolam), HIV protease inhibitors (eg, nelfinavir, ritonavir), macrolide antibiotics (eg, clarithromycin, erythromycin), nefazodone, olanzapine, opioid pain medicines (eg, oxycodone), perampanel, telithromycin, or tricyclic antidepressants (eg, amitriptyline) because they may increase the risk of Lunesta's side effects
  • Antihistamines (eg, chlorpheniramine, diphenhydramine), medicines for mental or mood disorders (eg, haloperidol, thioridazine), or medicines for seizures (eg, carbamazepine, phenobarbital, phenytoin) because the risk of their side effects, including drowsiness and decreased coordination, may be increased by Lunesta

This may not be a complete list of all interactions that may occur. Ask your health care provider if Lunesta may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.

How to use Lunesta:

Use Lunesta as directed by your doctor. Check the label on the medicine for exact dosing instructions.

  • Lunesta comes with an extra patient information sheet called a Medication Guide. Read it carefully. Read it again each time you get Lunesta refilled.
  • Take Lunesta by mouth. Do not take Lunesta with, or immediately after, a meal.
  • Lunesta works very quickly. Take it right before getting into bed. This will help to decrease the risk of falling and other side effects.
  • If you miss a dose of Lunesta and you are taking 1 dose daily at bedtime, skip the missed dose. Do not take the dose in the morning or take 2 doses at once.

Ask your health care provider any questions you may have about how to use Lunesta.

Important safety information:

  • Lunesta may cause drowsiness or dizziness. These effects may be worse if you take it with alcohol or certain medicines. Use Lunesta with caution. Do not drive or perform other possibly unsafe tasks after taking Lunesta. You may still feel sleepy the day after you take Lunesta. Avoid driving and performing other possibly unsafe tasks until you feel fully awake.
  • If your dose is 3 mg, continue to avoid driving and performing other possibly unsafe tasks the day after you take Lunesta. Do this even if you feel fully awake.
  • Do not drink alcohol while you are taking Lunesta. Do not take Lunesta if you drank alcohol earlier in the evening or before bed.
  • Check with your doctor before you use medicines that may cause drowsiness (eg, sleep aids, muscle relaxers) while you are using Lunesta; it may add to their effects. Ask your pharmacist if you have questions about which medicines may cause drowsiness.
  • Do NOT take more than the recommended dose or take for longer than prescribed without checking with your doctor.
  • Some patients taking Lunesta have performed certain activities while they were not fully awake. These have included sleep-driving, making and eating food, making phone calls, and having sex. Patients often do not remember these events after they happen. Such an event may be more likely to occur if you use a high dose of Lunesta. It may also be more likely if you drink alcohol or take other medicines that may cause drowsiness while you use Lunesta. Tell your doctor right away if such an event happens to you.
  • Do not take Lunesta unless you can get a full night's sleep (at least 7 to 8 hours) before you need to be active again.
  • If your symptoms do not get better within 7 to 10 days or if they get worse, check with your doctor.
  • When you stop taking Lunesta, you may notice some trouble sleeping the first few nights after the medicine is stopped. This usually goes away after 1 or 2 nights.
  • If you or your family notice any changes in your behavior (eg, more outgoing or aggressive behavior than normal, confusion, strange behavior, agitation), or if you have any unusual or disturbing thoughts, contact your doctor immediately.
  • Use Lunesta with caution in the ELDERLY; they may be more sensitive to its effects.
  • Lunesta should not be used in CHILDREN younger than 18 years old; safety and effectiveness in these children have not been confirmed.
  • PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Lunesta while you are pregnant. It is not known if Lunesta is found in breast milk. If you are or will be breast-feeding while you use Lunesta, check with your doctor. Discuss any possible risks to your baby.

When sleep medicines are used every night for more than a few weeks, they may lose their effectiveness to help you sleep. This is known as TOLERANCE. Sleep medicines should usually be used only for short periods of time, such as a few days and generally no longer than 1 or 2 weeks. If your sleep problems continue, contact your doctor.

When used for longer than a few weeks or at high doses, some people develop a need to continue taking Lunesta. This is known as DEPENDENCE or addiction.

If you stop taking Lunesta suddenly, you may have WITHDRAWAL symptoms. This may include unpleasant feelings. In more severe cases, you may have anxiety, abnormal dreams, nausea, or stomach upset.
