Sleep Medication Costs: Prescription vs OTC in Canada

The Cost of Sleepless Nights

Insomnia affects approximately one in three Canadian adults at some point, and chronic insomnia impacts about 10% of the population. The sleep aid market — both prescription and OTC — generates hundreds of millions in annual sales in Canada. But not all options are created equal in terms of effectiveness, safety, or cost.

OTC Sleep Aids

Antihistamine-Based

Product	Active Ingredient	Cost/Month	Effectiveness
ZzzQuil	Diphenhydramine 50mg	$12–$20	Short-term only
Unisom SleepTabs	Doxylamine 25mg	$8–$14	Short-term only
Benadryl	Diphenhydramine 25mg	$6–$12	Short-term only
Store-brand diphenhydramine	Diphenhydramine 25mg	$4–$8	Short-term only

Important: Antihistamine sleep aids are not recommended for long-term use. Tolerance develops within 1–2 weeks, and older adults face increased risk of confusion, falls, and cognitive impairment. The Canadian Geriatric Society specifically recommends against their use in seniors.

Melatonin

Product	Dose	Cost/Month	Evidence
Brand melatonin (Jamieson)	3–5mg	$8–$15	Moderate for sleep onset
Store-brand melatonin	3–5mg	$5–$10	Same efficacy
Slow-release melatonin	2–5mg	$10–$18	Better for sleep maintenance

Melatonin is most effective for circadian rhythm issues (jet lag, shift work) rather than chronic insomnia. It is safe for long-term use and very affordable.

Other OTC Options

Magnesium glycinate: $10–$20/month. Moderate evidence for mild insomnia.
Valerian root: $8–$15/month. Weak evidence; may help some people.
L-theanine: $12–$20/month. Limited evidence as a standalone sleep aid.
CBD oil: $40–$120/month. Limited evidence; not regulated as a sleep medication.

Prescription Sleep Medications

Short-Term Options (2–4 weeks)

Medication	Brand	Generic Cost/Month	Brand Cost/Month	Coverage
Zopiclone	Imovane	$8–$18	$40–$60	Covered (all provinces)
Zolpidem	Sublinox	$25–$40	$55–$80	Limited coverage
Temazepam	Restoril	$10–$20	$35–$55	Covered (most provinces)
Triazolam	Halcion	$12–$25	$45–$70	Covered

Zopiclone is the most commonly prescribed sleep medication in Canada and one of the cheapest at $8–$18/month generic. However, it is intended for short-term use (2–4 weeks) due to tolerance and dependence risks.

Longer-Term Options

Medication	Primary Use	Generic Cost/Month	Evidence for Insomnia
Trazodone 25–50mg	Antidepressant	$6–$15	Strong (off-label)
Mirtazapine 7.5–15mg	Antidepressant	$8–$18	Moderate (off-label)
Quetiapine 25–50mg	Antipsychotic	$10–$25	Moderate (off-label)
Gabapentin 100–300mg	Anticonvulsant	$8–$20	Moderate
Doxepin 3–6mg	Antidepressant	$12–$25	Strong (on-label in US)

Trazodone at low doses (25–50mg) is the most commonly prescribed long-term sleep medication in Canada. At $6–$15/month generic, it is both effective and affordable.

Suvorexant (Belsomra)

A newer dual orexin receptor antagonist:

Cost: $120–$180/month (no generic available)
Coverage: Limited; requires Special Authorization in most provinces
Evidence: Effective but expensive

Cost Comparison: Annual Treatment

Approach	Monthly Cost	Annual Cost
Store-brand melatonin	$5–$10	$60–$120
Generic zopiclone (short-term)	$8–$18	$96–$216
Low-dose generic trazodone	$6–$15	$72–$180
Brand suvorexant (Belsomra)	$120–$180	$1,440–$2,160
OTC diphenhydramine	$4–$8	$48–$96
CBT for insomnia (CBT-I)	$150–$250/session (6–8 sessions)	$900–$2,000 (one-time)

The Best Value Approach

Sleep experts recommend this order:

CBT for insomnia (CBT-I) — the gold standard with lasting results. Available free through some provincial programs (Ontario's BEACON, BC's BounceBack).

Generic trazodone ($6–$15/month) — effective, safe for longer-term use, covered by all provincial plans.

Melatonin ($5–$10/month) — useful for circadian issues, safe long-term, no prescription needed.

Generic zopiclone ($8–$18/month) — effective short-term while other approaches take effect.

Savings Tips

Avoid brand-name sleep aids. Generic zopiclone works identically to Imovane at a fraction of the cost.

Buy store-brand melatonin. Kirkland and Equate are 40–60% cheaper than branded products.

Use TransparentMedz to compare pharmacy prices on prescription sleep medications.

Ask about free CBT-I programs in your province before relying solely on medication.

Avoid long-term OTC antihistamines. They are not effective long-term and carry health risks.

The Bottom Line

Effective insomnia treatment does not have to be expensive. Generic trazodone and melatonin together cost under $25/month, and free CBT-I programs are increasingly available. Use TransparentMedz to find the lowest prices and talk to your doctor about the safest long-term approach.
