Why Is Disulfiram So Hard to Find? [Explained for 2026]

If you've been prescribed disulfiram and walked away from the pharmacy empty-handed, you're not imagining things. Since mid-2024, disulfiram has been listed on the ASHP drug shortage database, with at least one major presentation confirmed unavailable. For patients in alcohol use disorder (AUD) recovery, a gap in this medication can put sobriety at serious risk.

This article explains exactly why disulfiram is difficult to find in 2026, which specific presentations are affected, and what your practical options are right now.

What Is Disulfiram and Why Does It Matter?

Disulfiram — once sold under the brand name Antabuse — is one of only three FDA-approved medications for alcohol use disorder. It works by blocking the enzyme aldehyde dehydrogenase (ALDH2), causing a highly unpleasant physical reaction (flushing, nausea, vomiting, rapid heartbeat, and more) whenever alcohol is consumed. This aversion effect is the entire point: it makes drinking deeply uncomfortable, helping motivated patients stay sober.

Unlike naltrexone or acamprosate — both first-line AUD treatments — disulfiram doesn't reduce cravings. Instead, it acts as a chemical deterrent. Patients who are truly committed to sobriety and want an enforceable accountability tool often turn to disulfiram for exactly that reason.

Is Disulfiram Actually in Shortage Right Now?

Yes. The American Society of Health-System Pharmacists (ASHP) created a disulfiram shortage alert in July 2024, and it was updated in May 2025, indicating the situation had not fully resolved. Specifically, the Chartwell 500 mg tablet (NDC 62135-0432-90, bottle of 90 count) has been listed as unavailable. Alvogen also has at least one presentation unavailable, with no resupply date provided.

While there are four total presentations of disulfiram on the U.S. market, having one or more unavailable creates real gaps — especially when pharmacies that stock a particular manufacturer's product suddenly can't reorder it. Patients get caught in the middle.

Why Is Disulfiram Hard to Find? The Root Causes

Several factors combine to make disulfiram an unusually fragile part of the pharmaceutical supply chain:

• Few manufacturers. Disulfiram is an old, inexpensive generic drug. Only a handful of manufacturers produce it. When one has a production issue, supply quickly tightens across the country.
• Brand discontinuation. The brand-name Antabuse was discontinued. While generics filled the gap, the transition reduced the number of reliable supply pipelines.
• Low market incentive. Generic disulfiram retails for around $120-$157 for a 30-day supply, but discount cards push the price to under $40. Low profit margins mean manufacturers have little financial incentive to invest in production capacity.
• Concentrated generic manufacturing. Much of U.S. generic drug manufacturing happens at a limited number of overseas facilities. Ingredient shortages, regulatory issues, or production slowdowns at one site can affect multiple drugs simultaneously.
• Uneven pharmacy stocking. Because disulfiram is a niche AUD medication, many pharmacies — especially smaller ones — don't stock it routinely. You may find it at some chains and not others, even in the same zip code.

Which Disulfiram Presentations Are Affected?

The confirmed unavailable presentations as of the most recent ASHP update include:

• Chartwell 500 mg tablets (NDC 62135-0432-90, 90-count bottle) — listed as unavailable
• At least one Alvogen presentation — unavailable with no resupply date provided

The 250 mg tablet is more widely available than the 500 mg. If your provider can write for 250 mg and you need the equivalent dose, it may be easier to fill. Always check with your prescriber before changing doses.

What Happens If You Can't Fill Your Disulfiram Prescription?

For patients in recovery, a medication gap is never trivial. If you cannot fill disulfiram:

1. Contact your prescriber immediately. Do not simply stop taking disulfiram without guidance. Your doctor may be able to switch to naltrexone or acamprosate while you search.
2. Call multiple pharmacies. Availability varies block by block. Major chains, independent pharmacies, and compounding pharmacies may all have different stock.
3. Ask about a different manufacturer. If one brand's 500 mg is out, another manufacturer's 250 mg or 500 mg may be in stock at the same or different pharmacy.
4. Consider a compounding pharmacy. In some cases, a licensed compounding pharmacy can prepare disulfiram when commercial supply is unavailable. Discuss this with your prescriber.

How medfinder Can Help

Rather than calling pharmacy after pharmacy on your own, medfinder does the legwork for you. You tell us the medication, dosage, and your location — medfinder contacts pharmacies near you to find which ones can actually fill your prescription. Results come directly to your phone via text. It's a fast, practical solution when disulfiram is hard to find in your area.

Will the Disulfiram Shortage Resolve?

Drug shortages for inexpensive generics like disulfiram can be unpredictable. There is no publicly stated resupply date for the unavailable Alvogen presentation. Supply may improve if another manufacturer ramps production, but there is no guarantee of timing. The best approach is to stay informed, keep your prescriber in the loop, and use tools like medfinder to locate available stock.
