Learn how to save money on Cardizem XR (Diltiazem ER) in 2026. Compare prices, find coupons, discount cards, and patient assistance programs.
If you've been handed a bill of $200 or more for Cardizem XR at the pharmacy counter, you might be wondering how a blood pressure medication can cost so much. Here's the good news: there are many ways to bring that price down dramatically — and in many cases, you can get generic Diltiazem ER for less than $15 a month.
This guide covers everything you need to know about the cost of Cardizem XR in 2026, from cash prices and insurance coverage to discount cards and patient assistance programs.
The cost depends on whether you're getting brand-name Cardizem XR or generic Diltiazem ER:
Brand-name pricing varies widely between pharmacies. Specialty and hospital-affiliated pharmacies sometimes charge more than retail chains.
Generic Diltiazem ER is one of the most affordable blood pressure medications available. If you're paying more than $20 a month for generic, you're likely paying too much.
Prescription discount cards are free to use and can save you 50–90% off the cash price of generic Diltiazem ER. Here are the most popular options:
GoodRx is the most widely known prescription discount service. A quick search for Diltiazem ER 240 mg shows prices as low as $4–$10 at many pharmacies. Visit goodrx.com to compare prices and get a free coupon.
SingleCare often matches or beats GoodRx pricing. Check singlecare.com for current prices on Diltiazem ER at pharmacies near you. Accepted at CVS, Walgreens, Walmart, and most major chains.
RxSaver by RetailMeNot compares prices across multiple discount programs at once, so you can find the absolute lowest price. Visit rxsaver.com.
Additional options include:
Pro tip: Prices vary between discount cards and between pharmacies. Always compare at least 2–3 options before filling your prescription. The cheapest pharmacy for GoodRx might not be the cheapest for SingleCare.
Walmart includes certain Diltiazem formulations on its $4 prescription list for a 30-day supply (or $10 for 90 days). Not all strengths or formulations may be included, so check with your local Walmart pharmacy or visit walmart.com for the current list. No insurance or discount card needed — just ask for the $4 price.
If you're uninsured, underinsured, or facing financial hardship, you may qualify for free or reduced-cost medication through patient assistance programs (PAPs):
The manufacturer of brand-name Cardizem, Bausch Health, has offered patient assistance programs for qualifying patients. Eligibility is typically based on income (usually at or below 200–300% of the Federal Poverty Level) and insurance status. Check bauschhealth.com for current program availability.
NeedyMeds.org maintains a comprehensive database of patient assistance programs, discount cards, and copay assistance for virtually every medication — including Diltiazem. Search for "Diltiazem" to see all available programs.
RxAssist.org is another resource for finding patient assistance programs. It's maintained by the National Alliance of State Pharmacy Associations and includes programs from pharmaceutical manufacturers, government agencies, and nonprofits.
RxHope.com helps patients connect with manufacturer-sponsored assistance programs. They'll help you navigate the application process.
If you're currently taking brand-name Cardizem XR and your doctor approves, switching to generic Diltiazem ER can save you $70–$300+ per month. Generic versions are therapeutically equivalent and contain the same active ingredient at the same strength.
Filling a 90-day prescription is almost always cheaper per pill than filling 30 days at a time. Many pharmacies offer significant discounts on 90-day supplies, and mail-order pharmacies are especially competitive for maintenance medications.
Online pharmacies often have lower overhead costs, which translates to lower prices:
If you have insurance, generic Diltiazem ER is typically covered as a Tier 1 or Tier 2 medication with copays ranging from $0 to $15. However, sometimes a discount card price is actually lower than your insurance copay — especially if you have a high-deductible plan. Compare both options at the pharmacy counter.
Many states offer prescription assistance programs for residents who meet income requirements. These can supplement or replace other discount options. Contact your state's Department of Health or search "[your state] prescription assistance program" online.
Here's a rough comparison of what you might pay through different channels:
As you can see, using a discount card or shopping around can reduce your cost by 90% or more compared to paying cash for the brand name.
Cardizem XR and generic Diltiazem ER are among the more affordable blood pressure medications available — especially when you use the right tools. Don't pay full cash price without first checking discount cards, comparing pharmacies, and asking about patient assistance programs.
