Struggling to find Carbidopa/Levodopa XR at your pharmacy? Learn why this Parkinson's medication is in short supply and what you can do in 2026.
You've been taking Carbidopa/Levodopa XR for months — maybe years — to manage your Parkinson's disease symptoms. Then one day your pharmacy tells you they can't fill your prescription. You call another pharmacy. Same answer. Suddenly, something that was routine becomes stressful.
If this sounds familiar, you're not imagining things. Carbidopa/Levodopa extended-release tablets have been affected by ongoing supply issues, and many patients across the country are struggling to find their medication in 2026.
In this article, we'll explain exactly what Carbidopa/Levodopa XR is, why it's so hard to find right now, and — most importantly — what you can do about it.
Carbidopa/Levodopa XR is an extended-release tablet used to treat the motor symptoms of Parkinson's disease. It combines two active ingredients:
The "XR" or "ER" (extended-release) formulation is designed to release the medication slowly over several hours, giving patients smoother symptom control and fewer ups and downs throughout the day. It's sometimes referred to as Sinemet CR, though the brand-name version has been discontinued and only generic versions remain.
For a deeper look at this medication, see our guide on what Carbidopa/Levodopa XR is, including uses and dosage.
There's no single reason Carbidopa/Levodopa XR is hard to find — it's a combination of factors that have built up over time. Here are the main ones:
After the brand-name Sinemet CR was discontinued by its manufacturer, the supply of extended-release tablets shifted entirely to generic drugmakers. Only a handful of companies — including Accord and Sun Pharma — produce these tablets. When even one manufacturer experiences a disruption, it can ripple across the entire supply chain.
Producing extended-release formulations is more complex than making immediate-release tablets. The specialized coatings and manufacturing processes involved mean that quality control issues or raw material shortages can slow production. These disruptions have been recurring in the pharmaceutical industry since the early 2010s.
As of 2025, Carbidopa/Levodopa extended-release tablets are listed on the American Society of Health-System Pharmacists (ASHP) drug shortage database. Certain strengths and NDCs (National Drug Codes) are in limited supply. This is an ongoing, recognized problem — not just a local issue at your pharmacy.
Parkinson's disease affects roughly one million Americans, and that number is expected to grow as the population ages. More patients needing Carbidopa/Levodopa means more pressure on an already strained supply.
