Antidepressant Cost: Generic SSRIs, Brand-Name Drugs, and GoodRx Savings

Generic sertraline costs $11 a month at Costco with GoodRx. The brand-name equivalent (Zoloft) costs $240 for the same dose at a retail pharmacy without a discount. These are the same molecule. The difference is entirely about whether you ask for generic.

Here’s what every major antidepressant actually costs — and how to pay less.

Generic SSRI Costs: The Affordable Tier

SSRIs (selective serotonin reuptake inhibitors) are the most commonly prescribed antidepressants. Nearly all have affordable generic versions that are chemically identical to the brand-name drugs.

SNRIs: The Next Tier

SNRIs (serotonin-norepinephrine reuptake inhibitors) are used for both depression and anxiety. Most have generic options, though some remain expensive.

Note: Pristiq (desvenlafaxine) has some generic competition but remains relatively expensive. Fetzima has no generic. Both are often pushed by pharmaceutical representatives, but for most patients, cheaper alternatives work comparably.

Other Antidepressant Classes

Bupropion (Wellbutrin) — Atypical antidepressant, also used for ADHD and smoking cessation. Generic bupropion SR/XL: $15–$40/month with GoodRx. Well-tolerated, no sexual side effects (unlike most SSRIs).

Mirtazapine (Remeron) — Noradrenergic antidepressant. Generic: $15–$30/month. Sedating at lower doses; useful for depression with significant insomnia or appetite loss.

Tricyclic antidepressants (amitriptyline, nortriptyline) — Older class, significant side effects but low cost: $10–$20/month generic.

Brand-only newer drugs:

• Trintellix (vortioxetine): $300–$600/month without insurance. No generic as of 2025.
• Auvelity (dextromethorphan/bupropion): $600–$900/month. No generic. Newer mechanism.

The “Medication Switching” Cost

Most people go through 1–3 antidepressants before finding the right fit. Each switch means:

• A follow-up prescriber visit to discuss the new medication ($150–$300 self-pay)
• A new prescription (cost depends on the drug)
• 4–6 weeks at therapeutic dose before evaluating effectiveness

Budgeting for 2–3 medication trials in the first year is realistic. With generic SSRIs at $10–$30/month each, the medication cost of switching is low. The prescriber visit cost is the bigger variable.

Insurance Coverage

Most insurance plans cover antidepressants as a Tier 1 (preferred generic) benefit. Your copay is typically $0–$10/month for generic SSRIs and SNRIs. Some plans have moved generic bupropion and escitalopram to a $0 copay as preventive care.

Brand-name antidepressants without generics (Trintellix, Fetzima) land on Tier 3 or Tier 4 formularies. Expect copays of $50–$150/month with insurance — still much less than retail, but significantly more than generics.

Prior authorization is sometimes required for brand-name antidepressants, especially on managed care plans. Your prescriber’s office typically handles this. If your first-line medications have been ineffective, document that in the prior auth request — it’s usually the key requirement for approval.
