What is this medicine?
How to Use This Medicine
To use this medication effectively, follow your doctor's instructions and read all accompanying information carefully. Take the medication within 30 minutes of bedtime, with or without food. Note that taking it with or immediately after a meal may delay its onset of action. If you continue to experience sleep difficulties after 7 to 10 days, consult your doctor.
It is crucial to take this medication only when you can devote a full night's sleep, lasting at least 7 to 8 hours, before resuming activities. This ensures your safety and the medication's effectiveness.

Store the medication at room temperature in a dry location, avoiding bathrooms. Keep it in a secure, inaccessible place, such as a locked box or area, to prevent accidental ingestion by children, other individuals, or pets. Dispose of unused or expired medication properly.

For guidance on disposal, consult your pharmacist, who may be aware of local drug take-back programs.
Missing a Dose
If you miss a dose, take it as soon as possible. However, if taking the missed dose would result in less than 7 hours of sleep before your next activity, skip the dose and resume your regular schedule. Do not take more than one dose of this medication in a 24-hour period.

Certain health conditions, such as narcolepsy (falling asleep unexpectedly) or liver problems.

Any medications, including prescription and OTC drugs, natural products, or vitamins, that you are currently taking. This is crucial because some medications, such as those used to treat HIV, infections, seizures, and other conditions, may interact with this medication.
* Note that this is not an exhaustive list of all potential interactions. Therefore, it is vital to discuss all your medications and health conditions with your doctor.
To ensure your safety, inform your doctor and pharmacist about all your medications, including prescription and OTC drugs, natural products, and vitamins, as well as any health problems you have. This will help determine whether it is safe to take this medication with your other medications and health conditions. Never start, stop, or change the dose of any medication without first consulting your doctor.
Precautions & Cautions
After taking this drug, avoid driving and other activities that require alertness for at least 8 hours, or until you feel fully awake. You may still experience drowsiness the day after taking this medication, which can impair your driving abilities and increase the risk of falling asleep while driving. If you feel excessively sleepy during the day after taking this drug and plan to drive, consult your doctor.
Do not exceed the prescribed dose or frequency of this medication. If your sleep problems persist, contact your doctor. Long-term use of this drug may lead to dependence.
Avoid consuming alcohol while taking this medication, and do not take it if you have had alcohol that evening or before bedtime. Before using marijuana, other forms of cannabis, or prescription or over-the-counter drugs that may cause drowsiness, consult your doctor.
Some individuals have reported performing tasks, such as driving, cooking, eating, or having sex, while not fully awake, often without recalling these events. If this occurs, inform your doctor.
If you regularly consume grapefruit juice or eat grapefruit, discuss this with your doctor, as it may interact with the medication.
This drug can cause drowsiness and reduced alertness, increasing the risk of falls, particularly in older adults. If you have concerns, consult your doctor. Additionally, if you have sleep apnea, chronic obstructive pulmonary disease (COPD), or other breathing problems, discuss the potential effects of this medication on your breathing with your doctor.
If you are 65 years or older, use this medication with caution, as you may be more susceptible to side effects.
Inform your doctor if you are pregnant, plan to become pregnant, or are breastfeeding, as you will need to discuss the benefits and risks of this medication for both you and your baby.
Overdose Information
Overdose Symptoms:
- Somnolence
- Fatigue
- Headache
- Dizziness
- Nausea
What to Do:
In case of overdose, contact a poison control center immediately (e.g., call 1-800-222-1222 in the US) or seek emergency medical attention. Treatment should be symptomatic and supportive. Gastric lavage or activated charcoal may be considered if appropriate.
Drug Interactions
Contraindicated Interactions
- Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin, ritonavir, cobicistat, indinavir, nelfinavir, saquinavir, telithromycin, conivaptan)
Major Interactions
- Moderate CYP3A4 inhibitors (e.g., fluconazole, diltiazem, erythromycin, verapamil, grapefruit juice) - reduce daridorexant dose to 25 mg
- Strong or moderate CYP3A4 inducers (e.g., rifampin, carbamazepine, phenytoin, phenobarbital, St. John's Wort, efavirenz) - avoid co-administration
Moderate Interactions
Confidence Interactions
Monitoring
Baseline Monitoring
Rationale: To rule out underlying sleep disorders (e.g., sleep apnea, restless legs syndrome) or psychiatric/medical conditions that may contribute to insomnia.
Timing: Prior to initiation of therapy
Rationale: To screen for depression or suicidal ideation, as insomnia may be a symptom of underlying depression, and treatment with hypnotics may unmask or worsen suicidal ideation.
Timing: Prior to initiation of therapy
Routine Monitoring
Frequency: Periodically, as clinically indicated
Target: Improved sleep onset, sleep maintenance, and daytime functioning
Action Threshold: Lack of efficacy may warrant re-evaluation of diagnosis or treatment plan.
Frequency: Regularly, especially during initial treatment
Target: Absence or minimal severity of side effects
Action Threshold: Persistent or severe adverse effects may require dose reduction or discontinuation.
Frequency: Regularly
Target: Absence of such behaviors
Action Threshold: If observed, discontinue daridorexant immediately.
Frequency: Regularly, especially in patients with pre-existing psychiatric conditions
Target: Stable mood and absence of suicidal ideation
Action Threshold: Prompt psychiatric evaluation and intervention if observed.
Symptom Monitoring
- Daytime somnolence
- Dizziness
- Headache
- Fatigue
- Nausea
- Abnormal dreams
- Sleep paralysis
- Hypnagogic/hypnopompic hallucinations
- Complex sleep behaviors (e.g., sleep-driving, sleep-eating, preparing and eating food, making phone calls, having sex, sleepwalking)
- Worsening depression
- Suicidal ideation or behavior
Special Patient Groups
Pregnancy
There are no adequate and well-controlled studies of daridorexant in pregnant women. Use during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Trimester-Specific Risks:
Lactation
It is not known if daridorexant is excreted in human milk. Daridorexant and its metabolites were present in the milk of lactating rats. Consider the developmental and health benefits of breastfeeding along with the motherβs clinical need for daridorexant and any potential adverse effects on the breastfed infant.
Pediatric Use
Safety and effectiveness have not been established in pediatric patients (under 18 years of age).
Geriatric Use
No dose adjustment is required based on age alone. However, elderly patients may be more sensitive to the effects of hypnotics and should be monitored for adverse reactions such as falls, dizziness, and cognitive impairment. The 25 mg dose should be considered if there are concerns about tolerability.
Clinical Information
Clinical Pearls
- Instruct patients to take Quviviq only when they are able to get a full night's sleep (at least 7 hours) before they need to be active again.
- Advise patients that Quviviq may cause next-day impairment, including impaired driving. Patients should be cautioned against driving or engaging in other activities requiring complete mental alertness until they know how Quviviq affects them.
- Assess patients for underlying medical or psychiatric conditions that may contribute to insomnia, as Quviviq treats the symptom of insomnia but not its underlying cause.
- Patients should be warned about the risk of complex sleep behaviors, which can occur with or without memory of the event. If such behaviors occur, the drug should be discontinued.
- Quviviq is not indicated for the treatment of narcolepsy.
Alternative Therapies
- Other Dual Orexin Receptor Antagonists (e.g., Suvorexant, Lemborexant)
- GABA-A receptor agonists (e.g., Zolpidem, Eszopiclone, Zaleplon, Temazepam)
- Melatonin receptor agonists (e.g., Ramelteon)
- Antidepressants with sedating properties (e.g., low-dose Doxepin, Trazodone)
- Cognitive Behavioral Therapy for Insomnia (CBT-I)
