Generic antidepressants cost roughly $4 to $30 per month at most U.S. pharmacies, making them among the most affordable prescription medications available. Brand-name and newer antidepressants, however, can run hundreds or even thousands of dollars monthly. The total cost depends on which medication you’re prescribed, whether a generic version exists, and what kind of insurance you have.
Generic Antidepressants: The Lowest-Cost Option
The most commonly prescribed antidepressants have been available as generics for years, which keeps their prices low. Pharmacoeconomic data on widely used generics shows daily costs well under a dollar. Sertraline (the generic of Zoloft) runs roughly $0.30 to $0.66 per day, which works out to about $9 to $20 per month. Fluoxetine (generic Prozac) falls in a similar range at $0.33 to $0.99 per day, or roughly $10 to $30 monthly. Venlafaxine (generic Effexor), a commonly used SNRI, is even cheaper at $0.18 to $0.38 per day.
These prices vary based on your dose, since higher doses use more medication. Many large pharmacy chains and warehouse stores offer generic antidepressants on their discount drug lists, sometimes for as little as $4 for a 30-day supply. GoodRx and similar discount tools can also bring prices down to single digits per month, even without insurance.
Brand-Name and Newer Medications
Not every antidepressant has a cheap generic alternative. Newer medications that are still under patent protection cost dramatically more. Trintellix (vortioxetine) and Viibryd (vilazodone), for example, can cost $300 to $500 or more per month without insurance. Auvelity, approved in 2022, carries a similarly high list price. These medications work through slightly different mechanisms and are typically prescribed after older, cheaper options haven’t worked well enough.
If your provider recommends a brand-name antidepressant, it’s worth checking the manufacturer’s website. Most offer copay savings cards that can reduce costs to $10 to $50 per month for commercially insured patients. These programs usually don’t apply to government insurance like Medicare or Medicaid.
Clinic-Based Treatments Like Spravato
Esketamine (Spravato), a nasal spray given in a clinic under medical supervision, sits in a completely different price category. The medication alone runs $600 to $900 per dose, and once you factor in the required clinic monitoring (you must stay for at least two hours after each dose), a single session costs $1,000 to $1,500 or more. During the first month, when sessions happen twice a week, total costs can reach $8,000 to $12,000. Ongoing monthly maintenance typically runs $2,000 to $5,000. Spravato is reserved for treatment-resistant depression, and many insurance plans do cover it, though prior authorization and documented treatment failures are almost always required.
What Insurance Typically Covers
Most health insurance plans, including Medicare Part D, Medicaid, and employer-sponsored plans, cover antidepressants. Medicare specifically requires plans to cover drugs in several “protected classes,” and depression medications are one of them. That doesn’t mean every antidepressant is covered equally, though.
Insurance plans organize medications into tiers. Tier 1, which includes most generics, carries the lowest copay, often $0 to $15. Tier 2 covers preferred brand-name drugs at a medium copay, typically $20 to $50. Tier 3 and specialty tiers cover non-preferred brands and high-cost medications, where copays can climb to $50 to $100 or more, sometimes with coinsurance (a percentage of the drug’s cost) instead of a flat copay.
If your plan doesn’t cover the specific antidepressant your provider prescribes, you can often request an exception or ask your provider to submit a prior authorization explaining why that particular medication is necessary.
The Cost Beyond the Pill
The medication itself is only part of what you’ll spend. Getting and maintaining a prescription requires regular appointments with a prescriber, whether that’s a psychiatrist, psychiatric nurse practitioner, or primary care doctor. An initial psychiatric evaluation, which typically runs 60 to 90 minutes and includes your first prescription, costs around $250 to $400 without insurance. Follow-up medication management visits, usually 15 to 30 minutes every one to three months, run $100 to $200 per session out of pocket.
With insurance, these visits are usually covered as specialist or primary care copays, ranging from $20 to $60 depending on your plan. Some telehealth platforms offer lower-cost medication management, with monthly subscription models running $50 to $100 that include both the visit and the prescription.
How to Lower Your Costs
Your single biggest lever is whether you’re taking a generic. If cost is a concern, let your provider know upfront. Most people start on a generic SSRI or SNRI anyway, since these are first-line treatments with decades of evidence behind them. The price difference between a $7 generic and a $400 brand-name medication rarely reflects a proportional difference in effectiveness for most patients.
- Pharmacy discount programs: Walmart, Costco, and other retailers offer select generics for $4 to $10 per month without insurance.
- Prescription discount cards: GoodRx, RxSaver, and similar tools aggregate pharmacy prices and often beat insurance copays for generics.
- Patient assistance programs: Pharmaceutical manufacturers offer free or reduced-cost medication to people who meet income requirements, including for brand-name drugs.
- Mail-order pharmacies: Many insurance plans offer 90-day supplies through mail order at a lower per-month cost than filling 30 days at a retail pharmacy.
- Medicaid and state programs: If your income qualifies, Medicaid covers antidepressants with minimal or no copay in most states.
For the majority of people, the out-of-pocket cost of a generic antidepressant plus regular follow-up visits is manageable, often comparable to what you’d spend on a streaming subscription each month. The costs rise steeply only when brand-name medications or clinic-based treatments like Spravato become necessary, and even then, insurance and manufacturer programs can close much of the gap.
