Why Is Dhivy So Hard to Find? [Explained for 2026]

If you've been prescribed Dhivy for Parkinson's disease and found yourself calling pharmacy after pharmacy with no luck, you're not alone. Dhivy is a relatively new, specialized formulation of carbidopa/levodopa — the gold-standard treatment for Parkinson's disease — and its availability can vary significantly depending on where you live and which pharmacy you use.

In this article, we break down exactly what Dhivy is, why it can be difficult to find, what's driving availability issues in 2026, and — most importantly — what you can do right now to get your prescription filled.

What Is Dhivy and Why Is It Different?

Dhivy (pronounced "divvy") is a brand-name carbidopa/levodopa tablet manufactured by Avion Pharmaceuticals. What makes it unique is its innovative tablet design: each tablet has three functional score lines, allowing it to be snapped cleanly into four equal segments. Each full tablet contains 25 mg of carbidopa and 100 mg of levodopa. Each quarter segment contains 6.25 mg of carbidopa and 25 mg of levodopa — the smallest precisely doseable unit of carbidopa/levodopa available on the U.S. market.

The FDA approved Dhivy in November 2021, and it became commercially available in February 2022. It was developed by two neurologists who recognized that Parkinson's patients often needed more precise dose adjustment than standard tablets allowed — particularly patients experiencing motor fluctuations who needed to fine-tune their levodopa dose in increments smaller than 50 mg.

Is Dhivy Actually in Shortage?

The short answer: Dhivy as a product is not on an official FDA or ASHP shortage list. However, that doesn't mean it's always easy to find. Here's what's actually happening:

Dhivy is a brand-name specialty product from a smaller manufacturer. Unlike generic carbidopa/levodopa — which dozens of manufacturers produce and virtually every pharmacy stocks — Dhivy is carried by a more limited number of pharmacies. Chain pharmacies like CVS, Walgreens, and Rite Aid may or may not stock it routinely. Independent pharmacies and specialty pharmacies may be better sources.

It's brand-only — no generic.

As of 2026, there are no FDA-approved generic versions of Dhivy. This means patients cannot be automatically switched to a generic equivalent that has the same unique four-segment design. Standard generic carbidopa/levodopa 25/100 mg tablets exist, but they do not have the same scoring technology and cannot be reliably divided into exact 6.25/25 mg quarter doses.

The broader carbidopa/levodopa supply picture.

While Dhivy's immediate-release formulation is relatively stable, the broader carbidopa/levodopa market has experienced significant disruption. Extended-release (ER) carbidopa/levodopa tablets remain on the ASHP drug shortage list as of early 2026. Orally disintegrating tablets (ODT) have been effectively discontinued after both Sun Pharma (December 2022) and Viatris (2021) stopped making them. This general supply stress around carbidopa/levodopa products creates confusion for patients and pharmacists alike.

Why Don't More Pharmacies Stock Dhivy?

There are several reasons why Dhivy may not be stocked at every pharmacy near you:

• Newer market entry: Dhivy only became commercially available in 2022. Newer products take time to penetrate the market and gain routine stocking across all pharmacies.
• Specialty manufacturer: Avion Pharmaceuticals is a specialty company, not a major generic manufacturer. Its distribution network may be narrower than large pharmaceutical companies.
• Low prescription volume: Pharmacies stock medications based on demand. If only a few patients in a given area are prescribed Dhivy specifically (rather than generic carbidopa/levodopa), the pharmacy has little incentive to keep it on the shelf.
• Insurance formulary gaps: Not all insurance plans prefer Dhivy. If insurers steer patients toward generic carbidopa/levodopa, pharmacy demand for Dhivy specifically stays low.

The Bigger Picture: Why Is Carbidopa/Levodopa Hard to Find in General?

Even beyond Dhivy's specific circumstances, the entire carbidopa/levodopa market has faced stress in recent years. Several forces are at work:

• Growing Parkinson's disease prevalence: The Parkinson's Foundation estimates nearly one million Americans are living with PD, and that number is rising as the population ages. More patients means more demand.
• Manufacturer consolidation: Several manufacturers have exited certain carbidopa/levodopa formulations. When fewer companies make a drug, supply is less resilient to disruptions.
• Thin profit margins for generics: Generic carbidopa/levodopa can cost as little as $9 per month. Those razor-thin margins mean manufacturers have little financial incentive to invest heavily in production capacity.
• The "eight Sinemet limit" barrier: Some pharmacies and insurance systems automatically flag prescriptions for more than eight carbidopa/levodopa tablets per day — based on original FDA labeling language. This creates an additional access barrier for patients with advanced Parkinson's who require higher doses.

What Should You Do If You Can't Find Dhivy?

If your usual pharmacy doesn't have Dhivy in stock, here are the most effective steps to take:

1. Use medfinder to locate it. Instead of calling dozens of pharmacies yourself, medfinder will contact pharmacies near you to find out which ones have Dhivy in stock and can fill your prescription. This saves hours of frustrating phone calls.
2. Ask your pharmacist to order it. Many pharmacies can order medications they don't routinely stock, often with a 1–2 day turnaround. Ask specifically if they can order Dhivy from their wholesaler.
3. Contact your neurologist or prescriber. Your doctor may be able to call ahead to pharmacies, submit a prior authorization if needed, or consider whether a bridge supply of generic carbidopa/levodopa 25/100 mg could work temporarily.
4. Try independent pharmacies. Independent and specialty pharmacies sometimes have better relationships with specialty manufacturers and may be able to source Dhivy more reliably than large chain pharmacies.
5. Start looking early. Don't wait until your last few pills. Start searching for your refill 10–14 days before you run out. This gives you time to locate Dhivy without creating a dangerous gap in your treatment.

A Warning: Never Stop Dhivy Abruptly

This is critical: never stop taking Dhivy or any carbidopa/levodopa product suddenly. Abrupt discontinuation can trigger a dangerous withdrawal syndrome similar to neuroleptic malignant syndrome, with symptoms including high fever, severe muscle rigidity, and confusion. If you cannot fill your prescription, call your neurologist immediately so they can help arrange a bridge supply or safe transition.

Is There a Generic for Dhivy?

As of 2026, there is no FDA-approved generic that replicates Dhivy's unique four-segment design. Generic carbidopa/levodopa 25/100 mg tablets are widely available from multiple manufacturers (Teva, Amneal, Sun Pharma, and others) and can serve as a therapeutic substitute — but they don't offer the same precision dosing capability. Talk to your neurologist before switching, since the quarter-segment dosing may be clinically important for managing your symptoms.
