Cosopt can cost up to $220 without insurance. Learn how to save with generic pricing, discount coupons, and patient assistance programs in 2026.
If you've been shocked by the price of Cosopt at the pharmacy counter, you're not alone. Brand-name Cosopt can cost $140 to $220 for a single 10 mL bottle without insurance. For a medication you need every single day to protect your vision, those costs add up fast.
The good news? There are several ways to dramatically reduce what you pay for Cosopt or its generic equivalent, Dorzolamide/Timolol. In this guide, we'll walk through every option — from generic substitution and discount coupons to patient assistance programs.
Here's what you can expect to pay out of pocket in 2026 without insurance or coupons:
That's the retail price. But almost nobody should be paying retail — keep reading for how to bring those numbers way down.
The single most important thing you can do to save money on Cosopt is to use the generic version. Generic Dorzolamide/Timolol contains the exact same active ingredients in the exact same concentrations as brand-name Cosopt. The FDA considers them therapeutically equivalent.
The price difference is dramatic:
That's a savings of $120 to $200 per bottle. If your prescription currently says "Cosopt," ask your doctor or pharmacist about switching to the generic. In most states, your pharmacist can automatically substitute the generic unless your doctor specifically writes "dispense as written."
Even for the generic, prices vary wildly between pharmacies. A discount coupon can cut the cost significantly. Here are the best options for Dorzolamide/Timolol in 2026:
GoodRx shows prices at pharmacies near you and provides free coupons. Generic Dorzolamide/Timolol starts at approximately $10-$15 at many pharmacies with a GoodRx coupon. Visit goodrx.com to compare prices.
SingleCare offers coupons for Dorzolamide/Timolol starting at approximately $15 for a 10 mL bottle. Available at most major pharmacies. Visit singlecare.com to get a coupon.
Additional coupon programs that may offer savings on Dorzolamide/Timolol include:
Important: Discount coupons cannot typically be combined with insurance copays. Compare your insurance copay to the coupon price and use whichever is lower. Your pharmacist can run both to see which saves you more.
If you're uninsured or underinsured and struggling to afford your medication, patient assistance programs (PAPs) may provide Cosopt or its generic at no cost or very low cost.
Merck, the manufacturer of brand-name Cosopt, offers a patient assistance program for eligible patients who cannot afford their medications. Eligibility is typically based on income and insurance status.
NeedyMeds is a nonprofit that maintains a database of patient assistance programs, discount cards, and other resources. Search for "Dorzolamide" or "Cosopt" on their website to find available programs.
RxAssist is another comprehensive database of patient assistance programs. It includes both manufacturer programs and independent charitable organizations that help patients afford prescription medications.
The nonprofit organization Prevent Blindness maintains a detailed list of financial assistance resources specifically for glaucoma patients, including eye drop assistance programs and links to manufacturer PAPs.
If you have insurance, generic Dorzolamide/Timolol is on most formularies as a Tier 1 or Tier 2 medication, meaning it should have a low copay (often $5-$20 per fill). Check your plan's formulary or ask your pharmacist what your copay would be.
If your plan covers brand Cosopt but at a higher tier, ask your doctor to write for the generic instead.
Many insurance plans offer lower copays for 90-day supplies through their mail-order pharmacy. This can save you money and reduce the hassle of monthly refills. Ask your insurance company about mail-order options.
Pharmacy prices for the same medication can vary by 50% or more. Use Medfinder or GoodRx to compare prices at pharmacies near you before filling your prescription. Costco pharmacies, Walmart, and independent pharmacies often have the lowest cash prices.
If you're between refills or trying a new medication, ask your ophthalmologist if they have samples of Cosopt or an alternative. Many practices keep samples of glaucoma medications that they can provide at no cost for short-term use.
Costco and Sam's Club pharmacies often offer significantly lower prices on generics — and you don't need a membership to use their pharmacies in most states. A 10 mL bottle of generic Dorzolamide/Timolol may cost as little as $10-$15 at these locations.
No one should have to choose between their vision and their budget. With generic Dorzolamide/Timolol available for as little as $10 to $15, discount coupons from GoodRx and SingleCare, and patient assistance programs for those in financial hardship, there are real options to make Cosopt affordable.
Start by asking your pharmacist for the generic, compare prices using discount coupons, and explore patient assistance programs if you need additional help. Your vision is worth protecting — and cost shouldn't be the barrier.
