Dayvigo

How hard is it to find Dayvigo in stock?

Dayvigo (lemborexant) is a brand-name prescription sleep medication, and we've assigned a findability score of 72 out of 100. While Dayvigo is not currently on the FDA shortage list and is manufactured in adequate supply by Eisai, its brand-only status and relatively niche prescribing patterns mean not every pharmacy keeps it on the shelf.

Why It Can Sometimes Be Hard to Find

Dayvigo has no generic version — it's a brand-only medication with a list price of $294 for a 30-day supply. Some pharmacies, especially independents, may not stock it routinely due to lower demand compared to older sleep medications like zolpidem (Ambien) or trazodone. Pharmacies tend to stock what's most commonly prescribed, and Dayvigo is still building market share as a newer drug class.

Because it's a Schedule IV controlled substance, Dayvigo requires a prescription and may have ordering lead times at pharmacies that don't regularly carry it. However, most major chain pharmacies (CVS, Walgreens, Walmart) can order it within 1–2 business days.

What This Means for Patients

Unlike acute-need medications, insomnia treatment allows some planning time. If your pharmacy doesn't have Dayvigo in stock, request they order it or check nearby pharmacies. Medfinder can help you quickly locate pharmacies with Dayvigo in stock near you.

Who Can Prescribe Dayvigo?

Any licensed prescriber can prescribe Dayvigo, including:

• Primary care physicians — most commonly prescribe insomnia medications
• Sleep medicine specialists — for complex or treatment-resistant insomnia
• Psychiatrists — often prescribe when insomnia co-occurs with anxiety, depression, or other mental health conditions
• Neurologists — may prescribe for sleep disorders
• Nurse practitioners and physician assistants — can prescribe in all states

As a Schedule IV controlled substance, Dayvigo requires a prescription but does not have the same prescribing restrictions as Schedule II medications. Many telehealth platforms can also prescribe Dayvigo for insomnia after an appropriate evaluation.

Is Dayvigo a controlled substance?

Yes, Dayvigo is a Schedule IV controlled substance under the Controlled Substances Act. This is the same classification as other sleep medications like zolpidem (Ambien), eszopiclone (Lunesta), and the other DORA, suvorexant (Belsomra).

Schedule IV means the drug has a lower potential for abuse relative to Schedule III substances. Clinical studies of lemborexant showed low abuse potential, and there is no evidence of physical dependence or withdrawal symptoms at recommended doses. However, as with all controlled substances, prescriptions cannot be transferred between pharmacies in some states, and refill policies may vary.

Common Side Effects of Dayvigo

Most Common

• Somnolence/drowsiness — the most frequently reported side effect, more common at 10 mg than 5 mg
• Headache
• Fatigue
• Dizziness
• Abnormal dreams or nightmares

Side effects are generally dose-dependent — the 5 mg dose is better tolerated than 10 mg. Most side effects are mild and tend to improve with continued use.

Serious but Rare

• Sleep paralysis — temporary inability to move or speak while falling asleep or waking up
• Hypnagogic/hypnopompic hallucinations — vivid experiences when falling asleep or waking
• Cataplexy-like symptoms — brief episodes of muscle weakness
• Complex sleep behaviors — sleepwalking, sleep-driving, or other activities while not fully awake (rare but serious)
• Worsening depression or suicidal ideation — monitor closely in patients with depression

Next-Day Impairment

As a CNS depressant with a 17–19 hour half-life, Dayvigo can impair next-day driving and activities. This risk increases at the 10 mg dose. Patients should ensure at least 7 hours of sleep before activities requiring full alertness.

Final Thoughts on Dayvigo

Dayvigo represents a newer, targeted approach to treating insomnia that works fundamentally differently from the older sleep medications many patients and providers are familiar with. By blocking orexin-driven wakefulness rather than broadly sedating the brain, it offers a more physiologically natural path to sleep with a lower risk of dependence and no rebound insomnia.

The main barriers are cost (brand-only at $294+ retail, though GoodRx coupons bring it to ~$135 and the Eisai savings card can reduce copays to $0–$30) and pharmacy stocking (not every pharmacy carries it routinely). For patients whose insomnia hasn't responded well to generic options or who want to avoid the dependence concerns associated with benzodiazepines and Z-drugs, Dayvigo is worth discussing with a provider.
