Antidepressant Costs in Canada: SSRI, SNRI, and Newer Options

The Cost Landscape for Antidepressants in Canada

Depression affects approximately 5.4 million Canadians, and antidepressant medications are one of the most commonly prescribed drug classes in the country. The cost difference between options is enormous — from as little as $5/month for a generic SSRI to $300+/month for newer treatments. Understanding the landscape can save you hundreds or thousands of dollars per year.

SSRIs: The First-Line Standard

Selective serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed antidepressants and offer the best value:

Bottom line: All generic SSRIs cost under $20/month and are covered by every provincial drug plan. If cost is a concern, start here.

SNRIs: When SSRIs Are Not Enough

Serotonin-norepinephrine reuptake inhibitors (SNRIs) are often prescribed when SSRIs are ineffective:

Generic SNRIs are slightly more expensive than SSRIs but still very affordable. Venlafaxine is the most cost-effective at $10–$25/month.

Atypical Antidepressants

Bupropion is notable for fewer sexual side effects and potential to help with smoking cessation. Trazodone is frequently prescribed off-label for insomnia at very low cost.

Newer and More Expensive Options

Esketamine (Spravato)

• Cost: $250–$400 per treatment session (twice weekly initially, then weekly/biweekly)
• Monthly cost: $1,000–$3,200 during initial phase
• Coverage: Limited; some private plans cover it after other treatments fail. Provincial coverage requires Special Authorization in most cases.
• Use: Treatment-resistant depression

Ketamine Infusions (Off-Label)

• Cost: $350–$600 per infusion at private clinics
• Typical protocol: 6 infusions over 2–3 weeks ($2,100–$3,600), then maintenance
• Coverage: Not covered by provincial plans. Some private insurance plans cover partially.

Psychedelic-Assisted Therapy (Emerging)

Psilocybin-assisted therapy is in clinical trials in Canada but not yet widely available. When it becomes available, costs are expected to be $1,500–$5,000 per treatment course due to the required therapeutic supervision.

How to Choose Based on Cost and Effectiveness

For most people, the decision tree looks like this:

Start with a generic SSRI ($5–$20/month). Sertraline and escitalopram have the best evidence profiles.

If the first SSRI fails, try a second SSRI or switch to a generic SNRI ($10–$35/month).

Add bupropion ($15–$30/month) as an adjunct if partial response.

Consider atypical options (mirtazapine, trazodone) for specific symptoms like insomnia or appetite loss.

Explore esketamine or ketamine only after multiple adequate trials of standard medications.

Savings Strategies

Always use generics. Switching from brand Cipralex to generic escitalopram saves $50–$65/month ($600–$780/year).

Use TransparentMedz to compare pharmacy prices. Generic antidepressant pricing varies by $5–$15 between pharmacies.

Request 90-day supplies to reduce dispensing fees from 12 to 4 per year.

Check provincial coverage. All provinces cover generic SSRIs and SNRIs. If you are uninsured, apply for your provincial drug program.

Pill splitting (with doctor approval): Some antidepressants cost the same regardless of dose. A 20mg escitalopram tablet split in half gives two 10mg doses at the price of one.

Do Not Let Cost Prevent Treatment

Untreated depression costs far more than medication — in lost productivity, relationship damage, and physical health consequences. With generics starting at $5/month and provincial coverage available, there is no financial reason to go without treatment. Use TransparentMedz to find the best price and talk to your doctor today.

The Bottom Line

Generic SSRIs and SNRIs are remarkably affordable in Canada. The vast majority of people with depression can find an effective, well-tolerated medication for under $25/month. Save the expensive newer treatments for cases where standard medications have truly failed.
