Why is Amantadine so hard to find? [Explained for 2026]

Why Is Amantadine So Hard to Find Right Now?

If you or a loved one takes Amantadine for Parkinson's disease, dyskinesia, or another condition, you may have hit a frustrating wall at the pharmacy: "We don't have it in stock." You're not alone. Across the country, patients are struggling to find Amantadine, and the problem has been getting worse heading into 2026.

In this article, we'll explain exactly why Amantadine is so hard to find, what's behind the shortage, and what steps you can take right now to get your medication.

What Is Amantadine and Who Needs It?

Amantadine is a prescription medication used to treat several conditions, including:

• Parkinson's disease — to help with stiffness, tremors, and movement problems
• Levodopa-induced dyskinesia — the involuntary movements that can happen as a side effect of Parkinson's treatment
• Drug-induced extrapyramidal symptoms (EPS) — movement side effects from certain psychiatric medications

It's available as a generic immediate-release (IR) form and under brand names like Gocovri and Osmolex ER for extended-release versions. For a complete overview of the medication, see our guide on what Amantadine is, its uses, and dosage.

The Main Reasons Amantadine Is Hard to Find

1. Major Manufacturers Stopped Making It

The biggest reason Amantadine is scarce is simple: key manufacturers pulled out. Both Strides Pharma and Teva Pharmaceuticals — two of the largest generic drug makers — discontinued their 100 mg Amantadine hydrochloride capsules. These weren't recalls for safety reasons. They were business decisions.

When large manufacturers stop producing a drug, the remaining companies can't always pick up the slack fast enough. This creates a gap between supply and demand that can last months or even longer.

2. Limited Number of Remaining Manufacturers

With fewer companies making generic Amantadine, the supply chain becomes fragile. If even one of the remaining manufacturers has a production delay, quality control issue, or raw material shortage, the ripple effects hit pharmacies nationwide.

3. Increased Demand

As the population ages, the number of people living with Parkinson's disease continues to rise. More patients need Amantadine, but the supply hasn't kept pace — especially with manufacturers dropping out.

4. Supply Chain Disruptions

Ongoing global supply chain challenges affect pharmaceutical manufacturing just like any other industry. Raw material sourcing, shipping delays, and production bottlenecks can all slow things down.

Which Forms Are Most Affected?

The shortage has primarily hit Amantadine 100 mg capsules — the most commonly prescribed immediate-release form. However, you may have better luck finding:

• Amantadine 100 mg tablets (different dosage form, same drug)
• Amantadine oral solution (50 mg/5 mL liquid form)
• Gocovri or Osmolex ER (brand-name extended-release versions, though these are much more expensive)

Talk to your doctor about whether switching to a different form could work for you.

What Can You Do If You Can't Find Amantadine?

Here are practical steps to take right now:

Use a Pharmacy Finder Tool

Tools like MedFinder let you search for pharmacies that currently have Amantadine in stock near you. This can save you hours of calling around. Learn more in our guide on how to find Amantadine in stock near you.

Call Multiple Pharmacies

Don't give up after one pharmacy says no. Try independent pharmacies, not just the big chains. Smaller pharmacies sometimes have access to different distributors and may have stock when others don't.

Ask About Different Forms

If capsules aren't available, ask your pharmacist or doctor about switching to tablets or the oral liquid. The active ingredient is the same — it's just a different delivery method.

Talk to Your Doctor About Alternatives

If Amantadine simply isn't available, your doctor may suggest a temporary or long-term alternative. Options depend on why you're taking Amantadine. Read our full breakdown of alternatives to Amantadine.

Don't Stop Taking It Suddenly

This is critical: never stop Amantadine abruptly without talking to your doctor. Suddenly stopping can cause a dangerous reaction called neuroleptic malignant syndrome (NMS), which can include high fever, muscle stiffness, and confusion. Your doctor can help you taper safely if needed.

Will the Shortage End Soon?

There's no official timeline for when the Amantadine shortage will fully resolve. The FDA is monitoring the situation, and remaining manufacturers may increase production over time. However, with multiple companies having exited the market, a quick fix is unlikely.
