New Prescription Sleep Medications in Canada: A Look at QUVIVIQ and Dayvigo

If you have struggled with insomnia for more than a few weeks, you have probably wondered what your options are beyond melatonin and the older sleeping tablets. Over the past few years, a new class of prescription sleep medication has reached Canadian patients. These are called dual orexin receptor antagonists, or DORAs, and the two main options available in Canada are QUVIVIQ (daridorexant) and Dayvigo (lemborexant).

This article walks through what DORAs are, how QUVIVIQ and Dayvigo work, where they are similar, where they differ, and what you should know before talking to your doctor or a sleep specialist in Alberta.

What is a DORA, and why does it matter for insomnia?

Most older prescription sleep medication works by sedating the brain. Benzodiazepines, the so-called Z-drugs like zopiclone, and off-label use of antihistamines all sit somewhere in that category. They can make you feel drowsy enough to fall asleep, but they often leave you groggy the next day, and many of them carry a real risk of dependence with long-term use.

DORAs take a different approach. Instead of pushing the brain toward sleep, they quiet the wake signal. Orexin is a brain chemical that helps keep you alert during the day. A dual orexin receptor antagonist temporarily blocks the orexin receptors at night so that natural sleep can happen on its own. Because DORAs act as wake blockers rather than sedatives, they are not designed to knock you out, and they are generally not associated with the next-day grogginess that older sedating sleep medications can cause. In the published literature, patients who stopped these medications abruptly, even after about a year of continuous use, did not experience rebound insomnia or withdrawal, so DORAs are not thought to cause dependence or tolerance and are not considered habit forming. As with any prescription, they should still be used under medical guidance. In recent Canadian and European insomnia guidelines, DORAs are considered a first-line medication option for the treatment of chronic insomnia.

There are currently three DORA sleep medications approved in North America. Belsomra (suvorexant) was the first, but it is not available in Canada. Dayvigo (lemborexant) and QUVIVIQ (daridorexant) are the two DORA sleep medications that Canadian sleep clinics now talk about.

QUVIVIQ (daridorexant) at a glance

QUVIVIQ is made by Idorsia and was approved by Health Canada in 2023 for the management of adult patients with insomnia characterized by difficulties with sleep onset, sleep maintenance, or both. Uptake in Canadian sleep practices has grown through 2025 and into 2026 as more clinicians have become familiar with the DORA class. In plain language, the indication covers adults who have trouble falling asleep, staying asleep, or experience both.

A practical feature of QUVIVIQ is that it is prescribed at a single starting dose, without the need for titration.

QUVIVIQ is taken once nightly, about 30 minutes before bedtime. Your prescriber will confirm the right approach for you and review how well it works and how you tolerate it.

Dayvigo (lemborexant) at a glance

Dayvigo is made by Eisai and is also approved in Canada for adults with insomnia, with a similar indication around sleep onset and sleep maintenance.

Dayvigo is started at a lower dose that can be titrated upward if needed, based on how well it works for you and whether you notice any next-day effects.

Like QUVIVIQ, Dayvigo is taken once nightly before bedtime.

How QUVIVIQ vs Dayvigo compare on the things patients ask about

Both medications are dual orexin receptor antagonists, and both are intended for adults with insomnia. The main difference between the two is how they bind to and block the orexin receptors. They reach the same goal, quieting the wake signal, but they get there in slightly different ways.

On efficacy, both QUVIVIQ and Dayvigo treat sleep onset insomnia (trouble falling asleep) and sleep maintenance insomnia (trouble staying asleep) with similar effectiveness, and neither is meaningfully better than the other for staying asleep through the night. The two medications do have different half-lives, but that difference is not clinically meaningful from an efficacy or side effect standpoint, because both work as non-sedating wake blockers rather than sedatives. The clearest practical difference is dosing: QUVIVIQ is given as a single starting dose without titration, while Dayvigo is started at a dose that can be titrated if needed.

Neither medication is universally better than the other. The right choice depends on the pattern of your insomnia, your daytime demands, other medications you take, and your medical history. That is the kind of conversation to have with a sleep specialist, not something to settle from a comparison chart.

Side effects to be aware of

The most commonly reported side effects for both DORAs include headache, daytime drowsiness or somnolence, and unusual or vivid dreams. Less commonly, some patients have reported sleep paralysis or brief muscle weakness when waking. These risks are part of why these medications require a prescription and a careful conversation about your full medical history.

If you drive, operate heavy equipment, or have a job that demands quick reaction times in the morning, your prescriber will want to talk about timing and dose. Alcohol and other central nervous system depressants should generally be avoided while taking either medication.

Are QUVIVIQ and Dayvigo available in Canada?

Yes. Both QUVIVIQ and Dayvigo are approved by Health Canada and available with a prescription in Canada. Daridorexant is the generic name for QUVIVIQ, and lemborexant is the generic name for Dayvigo. Belsomra (suvorexant), the other DORA in the class, is not available in Canada.

Coverage is a separate question. Canada’s Drug Agency (CDA-AMC) has issued reimbursement recommendations that affect whether some DORAs are covered by public drug plans, which means coverage under Alberta Blue Cross and other plans can change over time. Private insurance plans vary widely. Before filling a prescription, ask your pharmacy to check current coverage and out-of-pocket cost so there are no surprises.

How to know if a DORA might be right for you

If you have tried sleep hygiene changes, cognitive behavioural therapy for insomnia (CBT-I), and over-the-counter options like melatonin without lasting results, a DORA may be worth discussing with a sleep specialist. The same is true if you have been on an older sleep medication for a long time and want to talk through safer long-term insomnia treatment.

At The Sleep Institute, we look at the full picture, including your sleep history, any related sleep disorders such as sleep apnea, daytime functioning, and your goals. From there we can talk through whether a DORA, a different prescription approach, or a non-medication path makes the most sense for your situation.

Frequently asked questions

Is QUVIVIQ stronger than Dayvigo? Neither medication is stronger in a meaningful sense. Both are dual orexin receptor antagonists with similar effectiveness for both falling asleep and staying asleep. They bind the orexin receptors somewhat differently and have different half-lives, but that half-life difference is not considered clinically meaningful for how well they work or how you feel the next day.

Is daridorexant available in Canada? Yes. Daridorexant is the generic name for QUVIVIQ and is approved by Health Canada.

Is Dayvigo legal in Canada? Yes. Dayvigo is approved by Health Canada for the management of adult patients with insomnia.

What is the newest sleeping pill in Canada? At the time of writing, QUVIVIQ is the most recently introduced prescription sleep medication in the DORA class in Canada. The landscape continues to evolve, so confirm with your prescriber or pharmacist for the most current options.

Can I buy QUVIVIQ or Dayvigo over the counter? No. Both require a prescription. Any product sold over the counter is not a DORA.

What is the best prescription sleeping pill in Canada? There is no single best prescription sleeping pill in Canada for every patient. The right choice depends on your sleep pattern, daytime demands, other medications, and medical history. Recent Canadian and European guidelines now list the DORA class, including QUVIVIQ and Dayvigo, as a first-line option for chronic insomnia, but the decision should always be made with a prescriber who knows your case.

Are DORAs addictive or habit forming? Based on the published literature, no. Patients who stopped these medications abruptly, even after about a year of use, did not show rebound insomnia or withdrawal, so DORAs are not thought to cause dependence or tolerance. They should still be used under medical guidance.
