Procainamide Shortage Update: What Patients Need to Know in 2026

Procainamide has been a lifesaving antiarrhythmic medication for over 70 years, but patients and caregivers are right to keep an eye on its availability. A past shortage rattled the supply chain, and the permanent discontinuation of oral formulations has created ongoing challenges for some patients. Here's a full update on procainamide's supply situation in 2026.

Current Procainamide Shortage Status (2026)

As of 2026, there is no active FDA-listed national shortage of procainamide hydrochloride injection. The drug is manufactured by multiple companies—including Amphastar Pharmaceuticals, Nexus Pharmaceuticals, and Pfizer—providing some redundancy in the supply chain.

However, patients and families should understand an important distinction: no national shortage does not mean universal availability. Procainamide is a specialty injectable drug primarily used in hospitals and emergency departments. Retail pharmacies rarely stock it, and access to compounded oral versions remains limited.

History of the Procainamide Shortage

In May 2017, the ASHP Drug Shortage Database documented a shortage of procainamide injection caused by manufacturing delays at Pfizer—at the time one of the primary suppliers. Hospitals and emergency departments across the country felt the impact, as this drug is often relied upon in acute cardiac events.

Nexus Pharmaceuticals stepped in by launching their version of procainamide injection in October 2017. By April 2018, ASHP confirmed that all marketed presentations of procainamide injection were available. The shortage lasted approximately 11 months—a significant disruption for a drug used in life-threatening situations.

The Oral Procainamide Situation: A Longer-Term Problem

While the injectable shortage was resolved, another availability issue has quietly persisted: oral procainamide tablets and capsules (Pronestyl, Procanbid extended-release) are no longer commercially manufactured in the United States. This is not an FDA shortage—it's a permanent market withdrawal.

Patients who were previously maintained on oral procainamide for long-term arrhythmia control now have two options:

Work with a compounding pharmacy to have oral procainamide prepared in capsule or liquid form (requires a special prescription and is not always covered by insurance)

Transition to an alternative antiarrhythmic medication under physician supervision (such as amiodarone, sotalol, or flecainide)

Why Procainamide Injection Is Still Difficult to Find at Pharmacies

Even without a formal shortage, patients who need procainamide outside of a hospital setting may struggle to locate it. The root cause is distribution: the vast majority of procainamide supply flows through hospital purchasing systems—not retail pharmacy chains.

If your doctor has prescribed procainamide for outpatient use, you may need to contact multiple pharmacies before finding one that stocks it. This is frustrating—but help is available.
