Acetylcysteine in 2026: Where Things Stand

If you rely on Acetylcysteine (also known as NAC or N-Acetylcysteine) for a lung condition or have needed it in an emergency, the past few years of spotty supply have probably been nerve-wracking. The good news heading into 2026 is that the picture has improved significantly. Here's everything you need to know about the current state of Acetylcysteine availability, pricing, and what to do if you still can't find it.

Is Acetylcysteine Still in Shortage?

As of September 2025, the American Society of Health-System Pharmacists (ASHP) updated Acetylcysteine's shortage status to resolved. All marketed presentations of the oral and inhalation solution are currently reported as available from manufacturers including Somerset Therapeutics and others.

However, "resolved" doesn't always mean "easy to find." Some pharmacies — particularly smaller ones or those in rural areas — may still experience occasional stock gaps. Supply chains take time to fully normalize after years of disruption, and some pharmacies have adjusted their ordering habits, keeping less inventory on hand than they used to.

The IV formulation (Acetadote) has also stabilized, though hospital pharmacies may still see periodic tightness depending on regional demand.

Why Was Acetylcysteine Hard to Find?

Acetylcysteine has been on the ASHP drug shortage list since June 2011 — one of the longest-running shortage entries in the database. Several factors contributed:

• Manufacturing issues: A limited number of manufacturers produce Acetylcysteine. Production shutdowns, quality control problems, or delays at even one facility could ripple across the entire market.
• Regulatory uncertainty: The FDA's 2021 stance questioning whether NAC supplements qualified as dietary supplements caused disruption in the oral supplement market, though this was clarified in 2022.
• Increased demand: Growing interest in NAC for off-label uses — including antioxidant therapy, psychiatric support, and COPD management — pushed demand beyond what manufacturers planned for.
• Supply chain strain: Like many medications, Acetylcysteine was affected by broader pharmaceutical supply chain disruptions during and after the COVID-19 pandemic.

How Much Does Acetylcysteine Cost in 2026?

One advantage of Acetylcysteine being a generic medication is that it's relatively affordable compared to many drugs. Here's what you can expect to pay without insurance:

• Inhalation solution (10%, 30 mL): Starting around $14–$37
• Inhalation solution (20%, 90 mL): Around $22–$73
• IV solution (20%, 120 mL): $101–$206 (typically a hospital cost)
• Oral NAC capsules (600 mg, 60-count): $10–$25

Prescription discount cards from services like SingleCare and GoodRx can bring prices down further. SingleCare reports prices as low as $26.47 for a 30 mL vial of the 20% solution. For more savings strategies, see our guide: How to save money on Acetylcysteine.

Are There New Options in 2026?

While no brand-new formulations of Acetylcysteine have launched recently, the expanded availability of generic manufacturers has helped stabilize the market. Key developments include:

• Multiple generic manufacturers: Companies like Somerset Therapeutics, Fresenius Kabi, and American Regent all produce Acetylcysteine, reducing reliance on any single source.
• NAC supplement availability: After the 2021 FDA scare, NAC supplements are once again widely available from major supplement brands and online retailers.
• Compounding pharmacies: For patients who need specific formulations, compounding pharmacies remain an option to prepare customized Acetylcysteine solutions.
