Carbidopa/Levodopa XR Shortage Update: What Patients Need to Know in 2026

The Carbidopa/Levodopa XR Shortage: Where Things Stand in 2026

If you take Carbidopa/Levodopa XR for Parkinson's disease, you may have noticed something troubling: your pharmacy can't always fill your prescription. You're not alone. Carbidopa/Levodopa extended-release tablets have been in and out of shortage for years, and the situation continues into 2026.

In this article, we'll give you a clear picture of the current shortage, explain why it's happening, tell you what the medication costs right now, and share practical steps to find it in stock.

Is Carbidopa/Levodopa XR Still in Shortage?

Yes. As of early 2026, Carbidopa/Levodopa extended-release tablets remain on the American Society of Health-System Pharmacists (ASHP) drug shortage list. The shortage affects specific strengths and certain manufacturers — meaning some pharmacies may have one strength but not another, and availability can change from week to week.

The FDA is aware of the shortage and continues to work with manufacturers to increase supply. However, no specific resolution date has been announced.

Here's what the current picture looks like:

• 25 mg/100 mg ER tablets: Intermittently available. Some manufacturers (like Accord) have limited supply.
• 50 mg/200 mg ER tablets: Also affected. Availability varies by region and pharmacy.
• Immediate-release tablets: Generally available and not affected by the same shortage.
• Rytary (brand ER capsules): Available but significantly more expensive.

Why Is Carbidopa/Levodopa XR Hard to Find?

The shortage is the result of several overlapping problems:

Few Manufacturers

After the brand-name Sinemet CR was discontinued, only a small number of generic manufacturers continued to produce extended-release Carbidopa/Levodopa tablets. When one manufacturer experiences production issues, there aren't enough others to fill the gap.

Manufacturing Complexity

Extended-release tablets require specialized manufacturing processes — controlled-release coatings, precise formulation, and rigorous quality testing. These are harder to produce than standard immediate-release tablets, making the supply chain more fragile.

Raw Material Constraints

The active pharmaceutical ingredients (APIs) needed for Carbidopa and Levodopa must meet strict quality standards. Supply disruptions for these raw materials — whether from regulatory issues, factory shutdowns, or geopolitical factors — can slow production for months.

Growing Patient Demand

Approximately one million Americans live with Parkinson's disease, and that number is rising as the population ages. More patients need Carbidopa/Levodopa, putting additional pressure on an already constrained supply.

What Does Carbidopa/Levodopa XR Cost in 2026?

One of the frustrating side effects of a shortage is that prices can fluctuate. Here's what you can expect to pay:

• Generic Carbidopa/Levodopa ER tablets: The average retail price is $50 to $80 for a 30-day supply without insurance. With a GoodRx or SingleCare coupon, you can find it for as low as $29.
• Carbidopa/Levodopa immediate-release tablets: As low as $9 per month with a coupon — the most affordable option.
• Rytary (brand ER capsules): $800 to $1,500 per month without insurance. Manufacturer savings cards may reduce copays for commercially insured patients.
• Stalevo (generic Carbidopa/Levodopa/Entacapone): $54 to $100 per month with a coupon.

Are There New Options in 2026?

The Parkinson's treatment landscape continues to evolve. While no brand-new Carbidopa/Levodopa formulations have launched recently, here are some developments worth knowing about:

• Vyalev (Foscarbidopa/Foslevodopa) — A subcutaneous infusion approved for advanced Parkinson's patients with motor fluctuations. It delivers continuous Levodopa through a small pump worn under the skin. This is typically reserved for patients who don't respond adequately to oral medications.
• Duopa (Carbidopa/Levodopa enteral suspension) — An intestinal gel infusion delivered through a surgically placed tube. Also for advanced Parkinson's disease.
• Generic pipeline: Additional generic manufacturers may enter the extended-release tablet market, which would help ease the shortage. However, FDA approval timelines for generics can be unpredictable.

How to Find Carbidopa/Levodopa XR in Stock

Even during a shortage, Carbidopa/Levodopa XR is still being produced and distributed. The key is knowing where to look:

1. Use Medfinder

Medfinder lets you search for Carbidopa/Levodopa XR by your zip code and see which pharmacies near you have it in stock. It's the fastest way to find your medication without making dozens of phone calls.

2. Try Independent Pharmacies

Independent pharmacies often have better luck sourcing medications during shortages because they work with multiple distributors. They may be able to find stock that chain pharmacies can't.

3. Consider Mail-Order

Mail-order pharmacies like those offered through your insurance plan often have access to larger inventories. Just remember to plan ahead — shipping typically takes 7-14 days.

4. Ask Your Doctor About Switching Formulations

If you absolutely can't find the XR tablets, your neurologist can help you transition to an alternative. See our article on alternatives to Carbidopa/Levodopa XR for a full comparison.
