Lithium Carbonate can cost as little as $7 with the right coupon. Learn how to use GoodRx, SingleCare, and patient assistance programs to reduce your out-of-pocket costs in 2026.

Lithium Carbonate is one of the most affordable psychiatric medications available—yet many patients still pay more than they need to. The average retail price for a 30-day supply of generic Lithium Carbonate 300 mg tablets is approximately $30–$55 without insurance or discounts. With the right coupon or discount program, that same prescription can cost as little as $7–$13. Here is how to pay less.

How Much Does Lithium Carbonate Cost Without Insurance?

Prices vary by strength, formulation, quantity, and pharmacy:

300 mg tablets (30-day supply): $30–$55 retail; $7–$13 with GoodRx or SingleCare coupon

300 mg capsules (90-count): Retail around $31; as low as $6 with SingleCare

450 mg ER tablets (60-count): Retail around $45; as low as $9 with SingleCare

300 mg ER tablets (Lithobid brand, 30-count): $41–$55 retail; $5–$13 with GoodRx coupon for generic ER

These prices make generic Lithium Carbonate competitive even compared to Tier 1 insurance copays. In many cases, using a coupon at a preferred pharmacy is cheaper than your insurance copay—it is always worth comparing.

How to Use GoodRx for Lithium Carbonate

GoodRx is the most widely used prescription discount service in the U.S. Here is how to use it for Lithium Carbonate:

Go to goodrx.com and search "Lithium Carbonate"

Enter your dosage and quantity (e.g., 300 mg, 90 tablets for a 30-day TID supply)

Enter your zip code to compare prices at pharmacies near you

Select the lowest price and receive your coupon by text, email, or print

Show the coupon to your pharmacist at drop-off—before the prescription is filled

Important: You cannot use a GoodRx coupon simultaneously with Medicare or Medicaid. But if you have insurance that prices the medication higher than a GoodRx coupon, you can choose to use the coupon instead and pay cash.

SingleCare: Another Strong Option

SingleCare (singlecare.com) is a GoodRx competitor with similarly deep discounts on generic Lithium Carbonate. SingleCare coupons can bring the 90-count 300 mg capsule supply to as low as $6, and the 60-count 450 mg ER to around $9. Like GoodRx, SingleCare coupons cannot be combined with insurance. It is worth checking both services at your preferred pharmacy—prices can differ by a few dollars depending on the retailer.

Is Lithium Carbonate Covered by Insurance?

Yes—for most commercially insured patients, generic Lithium Carbonate is covered as a Tier 1 or Tier 2 drug, resulting in a copay of $0–$30 per fill depending on your plan. Most employer-sponsored plans, ACA marketplace plans, Medicaid, and CHIP cover lithium carbonate. Medicare Part D coverage varies by plan—check your specific plan's formulary, as some Part D plans place lithium on a higher tier or require step therapy authorization.

Patient Assistance Programs

Because Lithium Carbonate is a generic without a major brand manufacturer, there is no single-manufacturer patient assistance program (PAP) like those offered by Pfizer or AstraZeneca. However, several resources can help uninsured or underinsured patients:

NeedyMeds (needymeds.org): A comprehensive database of PAPs, disease-specific programs, and clinic resources that assist with medication costs. Lists programs even for generic drugs.

RxAssist (rxassist.org): A database of manufacturer PAPs and other drug cost assistance programs.

State pharmaceutical assistance programs: Many states offer drug assistance programs for low-income residents, especially those who do not qualify for Medicaid but are under a certain income threshold.

Community mental health centers: Federally Qualified Health Centers (FQHCs) and community mental health clinics often have access to 340B-priced medications, which can make lithium carbonate nearly free for qualifying patients.

90-Day Supply vs. 30-Day Supply: Save More with Bigger Fills

Filling a 90-day supply instead of monthly typically reduces your cost-per-day by 15–25%. If you are on a stable dose with current monitoring labs, ask your prescriber to write a 90-day supply. Mail-order pharmacies (often offered through your insurance) may also provide 90-day fills at the equivalent of just 2 monthly copays.

If cost is a barrier and you are also having trouble finding your specific dose in stock, medfinder can help you quickly identify which pharmacies carry your dose—and you can then use a GoodRx or SingleCare coupon there. See also: How to Find Lithium Carbonate in Stock Near You.

Frequently Asked Questions

With a GoodRx coupon, Lithium Carbonate 300 mg tablets can cost as little as $7.57 for a common quantity at major chain pharmacies—86% off the average retail price of approximately $55.25. The actual discounted price varies by pharmacy and quantity. Check goodrx.com with your specific dose and zip code for the most current pricing.

Coverage varies by plan. Some Medicare Part D plans do cover lithium carbonate, but GoodRx notes that in general, many standard Medicare Part D plans do not cover it. Check your specific plan's formulary at Medicare.gov or call your plan directly. If it is not covered, a GoodRx or SingleCare coupon may cost less than your out-of-pocket price through Medicare.

Because lithium carbonate is a generic medication without a major brand manufacturer, there are no single-manufacturer programs like for brand-name drugs. However, NeedyMeds.org and RxAssist.org list programs for generic drug assistance. Community mental health centers and Federally Qualified Health Centers often provide Lithium Carbonate at very low or no cost to qualifying patients through 340B drug pricing.

Compare both options. For most commercial insurance plans, generic Lithium Carbonate is a Tier 1 drug with a $0–$10 copay, which may be cheaper than even GoodRx prices. However, if your plan has a high deductible or places lithium on a higher tier, a GoodRx coupon starting at $7–$13 is worth using instead. You cannot combine GoodRx with insurance at the same time.

Yes. Filling a 90-day supply rather than monthly typically costs less per day—often equivalent to 2 months' worth of copays for 3 months of medication through mail-order pharmacy. You also avoid the risk of refill gaps. Ask your prescriber to write a 90-day supply if your lithium levels are stable and monitoring is current.
