Generic carbamazepine costs roughly $80 to $200 at full retail price, depending on your dosage, formulation, and how many tablets you need. But almost nobody should pay that sticker price. Free discount coupons can bring the cost down to as little as $27 to $48 for a typical supply, making this one of the more affordable anticonvulsant medications even without insurance.
Retail Price by Formulation
The most commonly prescribed version is the 200mg immediate-release tablet. At full retail, 180 tablets runs about $196. Chewable tablets in the same strength cost around $163 for 90 tablets, and the liquid suspension (450 mL) lists at roughly $88.
Extended-release tablets cost more per pill. The per-unit price for extended-release carbamazepine starts around $0.43 per tablet, compared to $0.18 to $0.29 for immediate-release. That difference adds up quickly over a month, especially at higher doses. If your doctor has you on the extended-release version, expect a 60-tablet supply of 200mg ER tablets to run about $27 to $43 with a discount coupon, depending on the pharmacy.
Prices Vary Significantly by Pharmacy
Where you fill your prescription matters more than you might expect. For a 60-count supply of carbamazepine ER 200mg, coupon prices at major chains break down like this:
- Walgreens: around $27
- CVS: around $29
- Walmart: around $43
For the immediate-release 200mg tablet (180 count), Walmart with a coupon comes in around $41, while CVS runs closer to $43. Smaller or regional chains sometimes beat the big names. Raley’s, for example, has been listed as low as $27 for that same 180-tablet supply.
How Discount Coupons Change the Math
Prescription discount programs like GoodRx dramatically reduce what you actually pay. For the most common version of carbamazepine, a free GoodRx coupon drops the price from roughly $168 to about $38, a 77% reduction. Paid membership tiers (like GoodRx Gold) can push that even lower, to around $27.
Here’s what coupon pricing looks like across formulations:
- 200mg tablets (180 count): around $38
- 100mg chewable tablets (180 count): around $32
- 200mg chewable tablets (90 count): around $48
- Oral suspension, 100mg/5mL (450 mL): around $31
These coupons are free, don’t require insurance, and work at most major pharmacies. You simply show the coupon (printed or on your phone) when you pick up your prescription. The pharmacist applies it at the register.
Generic vs. Brand Name
Carbamazepine is the generic form of Tegretol. Generic pricing starts as low as $0.13 to $0.33 per tablet for the 200mg strength, which puts a 100-tablet supply in the $13 to $33 range at the lowest available prices. Brand-name Tegretol is rarely prescribed today since the generic is widely available and identical in active ingredient. If your prescription specifies brand name for any reason, expect to pay substantially more.
There’s also Equetro, a brand-name extended-release capsule version used specifically for bipolar disorder. Equetro offers a copay card that provides up to $100 off a 30-day supply, $150 off a 60-day supply, or $200 off a 90-day supply for eligible patients. That card is designed for people with some insurance, though, so it may not help if you’re paying entirely out of pocket.
Getting Carbamazepine for Free
If you’re uninsured and can’t afford even the discounted price, Novartis (the manufacturer of Tegretol) runs a patient assistance foundation that provides certain medications at no cost. To qualify, you need to reside in the U.S., be treated by a licensed healthcare provider on an outpatient basis, and meet income guidelines. You’ll need to submit proof of income and complete an application with your provider. Decisions typically come back within four weeks.
Only you, a legal guardian, or a caregiver can enroll you in the program. Insurance companies and pharmacies cannot apply on your behalf. If you have government insurance, you may still be eligible, but people with private insurance generally are not.
Keeping Your Long-Term Costs Down
Since carbamazepine is a medication most people take continuously, small per-tablet savings compound over time. A few strategies are worth considering. First, always compare prices across at least three pharmacies using a discount tool before filling. Second, ask your doctor about the immediate-release formulation if you’re currently on extended-release, since the per-pill cost is roughly half (though dosing frequency increases, so this is a clinical decision, not just a financial one). Third, buying larger quantities tends to reduce the per-unit cost. The per-tablet price at 1,000 tablets can drop to $0.18 compared to much higher per-unit costs for smaller fills.
Wholesale ingredient prices for carbamazepine have been softening through 2025, with North American prices dropping about 15% in one recent quarter due to strong generic supply and lower institutional demand. That trend favors stable or slightly lower retail prices going forward.
