Cardizem Shortage Update for 2026

If you've been hearing about Cardizem shortages and wondering whether it affects your prescription, you're in the right place. The Diltiazem supply picture in 2026 is nuanced — some forms are harder to get than others, and the situation has evolved over the past several years. Here's what you need to know.

Is Cardizem Still in Shortage?

The answer depends on which form of Diltiazem you need:

• Oral Diltiazem (tablets and capsules): Generally available. Most patients taking Cardizem, Cardizem CD, Cardizem LA, Tiazac, Cartia XT, or generic Diltiazem by mouth should be able to fill their prescriptions — though specific formulations or strengths may be temporarily out of stock at certain pharmacies.
• Injectable Diltiazem (IV): Still in a long-running shortage that began in June 2015. This is a hospital product used for emergency heart rate control. As of early 2026, Hikma has vials on allocation and Pfizer supplies are intermittent. This is one of the longest drug shortages in American history — over 10 years and counting.

So while the headline "Cardizem shortage" is technically about the injectable form, the ripple effects can sometimes make oral formulations harder to find at specific pharmacies.

Why Is Diltiazem Hard to Find?

Several factors contribute to supply issues:

• Manufacturer exits. Akorn Pharmaceuticals shut down entirely in 2022, removing one of only a few injectable Diltiazem producers from the market.
• Non-interchangeable formulations. Diltiazem extended-release products (CD, LA, XR, XT) are not automatically substitutable. If your specific product is out, your pharmacy can't just give you a different ER version.
• Supply chain fragility. Generic drug manufacturing operates on thin margins. When one supplier has a production issue, it can take months to recover, and other manufacturers may not have capacity to fill the gap.
• Stocking decisions. Pharmacies stock based on demand patterns. Less common strengths (300 mg, 420 mg) may not be routinely stocked.

How Much Does Cardizem Cost in 2026?

The cost of Diltiazem depends on whether you're paying cash, using insurance, or have a discount card:

• Generic Diltiazem IR (immediate-release) tablets: $9-$20/month with discount coupons from GoodRx or SingleCare. Without coupons, retail cash prices run $50-$75 for a 30-day supply.
• Generic Diltiazem ER (extended-release) capsules: $15-$60/month with coupons. Without coupons, cash prices range from $55-$225 depending on strength and formulation.
• Brand-name Cardizem: $300-$500+/month. Most patients don't need the brand — generic works the same way and is much cheaper.
• With insurance: Generic Diltiazem is typically a Tier 1 or Tier 2 drug, with copays of $0-$15/month on most plans.

Are There New Options in 2026?

While no fundamentally new Diltiazem products have launched recently, the market continues to evolve:

• Multiple generic manufacturers (Teva, Mylan, Lupin, Aurobindo, and others) continue to produce oral Diltiazem, keeping prices competitive.
• Discount programs from SingleCare, GoodRx, and RxSaver offer prices as low as $9/month for generic Diltiazem, making it accessible even without insurance.
• If Diltiazem isn't available, well-established alternatives like Verapamil, Amlodipine, and Metoprolol are widely stocked and affordable.

How to Find Cardizem in Stock Right Now

If your pharmacy is out of your specific Diltiazem formulation, here's what to do:

1. Search Medfinder to find pharmacies near you with Diltiazem in stock.
2. Call independent pharmacies — they often source from multiple wholesalers.
3. Ask your pharmacist to backorder or transfer your prescription to a pharmacy that has stock.
4. Talk to your doctor about switching formulations or trying a therapeutic alternative if your specific product is consistently unavailable.
5. Refill early — request your refill 7-10 days before you run out to give yourself a buffer.

Final Thoughts

The Cardizem supply situation in 2026 is manageable for most patients taking oral forms, but it pays to plan ahead. The injectable shortage is a long-standing crisis that primarily affects hospitals. If you take oral Diltiazem and are having trouble filling your prescription, use Medfinder, work with your pharmacist, and keep your doctor in the loop. Your heart medication is too important to leave to chance.
