Get the latest Amantadine shortage update for 2026. Learn which forms are affected, what the FDA is doing, and how patients can find their medication.
The Amantadine shortage that began affecting patients in 2024 continues into 2026. If you depend on this medication for Parkinson's disease, dyskinesia, or other conditions, this update covers everything you need to know — what's happening, why, and what you can do about it.
As of early 2026, Amantadine remains in limited supply at many pharmacies across the United States. The shortage primarily affects:
The FDA and the American Society of Health-System Pharmacists (ASHP) continue to track the situation. While not every pharmacy is affected, many patients report difficulty filling prescriptions, especially in certain regions.
The shortage stems from several overlapping factors:
The largest driver of the shortage is that Strides Pharma and Teva Pharmaceuticals both discontinued their Amantadine hydrochloride 100 mg capsule products. These were business decisions — not safety recalls. With two major manufacturers out, the remaining producers haven't been able to fully meet demand.
Generic medications like Amantadine often have thin profit margins. This means fewer companies are motivated to enter or expand production, even when demand rises. The economics of generic drug manufacturing are a systemic problem that affects many medications beyond Amantadine.
The number of Americans living with Parkinson's disease is increasing as the population ages. The Parkinson's Foundation estimates that nearly 1 million people in the U.S. live with the condition, with that number projected to rise. More patients means more prescriptions and more demand for drugs like Amantadine.
Pharmaceutical supply chains remain under stress from global disruptions affecting raw materials, shipping, and production schedules. Even small delays at one point in the chain can create downstream shortages.

The FDA monitors drug shortages and works with manufacturers to address supply gaps. Their role includes:
However, the FDA cannot force a company to manufacture a drug. The agency works within its regulatory authority to encourage resolution, but timelines depend on industry decisions.
While 100 mg capsules are most affected, other forms may still be available:
| Form | Availability | Notes |
|---|---|---|
| 100 mg capsules (generic) | Limited | Most affected by the shortage |
| 100 mg tablets (generic) | Better availability | Same drug, different form |
| Oral solution (50 mg/5 mL) | Generally available | Good option if you can't find solid forms |
| Gocovri (ER capsules) | Available | Brand-name; significantly more expensive |
| Osmolex ER (ER tablets) | Available | Brand-name; requires prior auth from many insurers |
Talk to your doctor about whether a different form could work for you.
If you still have Amantadine, plan ahead. Refill your prescription as early as your insurance allows — typically 7 days before your supply runs out. If you're on a 30-day supply, consider asking your doctor about switching to a 90-day mail-order prescription.

If the time comes when you truly can't find Amantadine in any form, your doctor can work with you on alternatives. We've outlined the options in our guide on alternatives to Amantadine.
We can't stress this enough: do not suddenly stop taking Amantadine. Abrupt discontinuation can trigger neuroleptic malignant syndrome (NMS), which can be life-threatening. If you're running low and can't find more, call your doctor immediately to discuss a safe plan.
Shortages can sometimes drive up costs, especially if you need to switch to a brand-name product. Here are ways to keep costs manageable:

There is no confirmed date for when the Amantadine shortage will fully resolve. As long as the number of manufacturers remains limited, supply will likely stay tight. However, as demand becomes more visible and advocacy grows, there's hope that additional manufacturers may enter the market.
