Why is Sunosi so Hard to Find? [Explained for 2026]

You're not imagining it. Sunosi (solriamfetol) can be genuinely difficult to find at your local pharmacy. While there's no active FDA shortage of Sunosi, patients with narcolepsy or obstructive sleep apnea (OSA) often report calling multiple pharmacies before finding their prescription in stock. Here's why — and what you can do about it.

Is Sunosi Actually in Shortage?

As of 2026, Sunosi is not on the FDA's official drug shortage list. The FDA tracks shortages of medically necessary drugs and Sunosi does not currently appear there. However, not being in an official shortage doesn't mean it's easy to find. Several structural factors make Sunosi harder to locate than a typical medication.

Why Do Pharmacies Run Out of Sunosi?

Sunosi is a brand-name only medication — there is currently no generic version of solriamfetol available, and one is not expected until 2042. That means pharmacies must stock the brand-name product, which is more expensive and has a more limited supply chain than a widely genericized drug.

Here are the main reasons you might struggle to find Sunosi in stock:

Lower stocking volume: Sunosi is prescribed for a relatively narrow set of conditions (narcolepsy and OSA-related sleepiness). Pharmacies stock based on local demand, so smaller pharmacies may only keep a few bottles on hand — or none at all.

Schedule IV controlled substance rules: Sunosi is classified as a Schedule IV controlled substance (CIV) by the DEA. Pharmacies have strict inventory and ordering requirements for controlled substances, which can limit how much they keep on hand at any time.

Brand-only means higher cost: With a retail cash price around $1,100–$1,200 per month, pharmacies are more cautious about over-ordering expensive brand-name drugs that may not sell quickly.

Distribution chain: Sunosi is now distributed by Axsome Therapeutics (previously Jazz Pharmaceuticals), and transitional distribution periods can sometimes affect availability at certain wholesalers.

Insurance prior authorization delays: Most insurers require prior authorization before covering Sunosi, and many require step therapy (trying modafinil or armodafinil first). This means patients often can't pick up Sunosi right away even if the pharmacy has it.

Which Strengths of Sunosi Are Most Commonly Available?

Sunosi comes in two strengths: 75 mg and 150 mg film-coated tablets. The 75 mg tablet can also be split in half (it has a score line) to provide the 37.5 mg starting dose for OSA patients. In practice, availability varies by pharmacy — one location may have 75 mg in stock but not 150 mg, or vice versa. Calling ahead or using a pharmacy availability service is the most efficient way to find your dose.

What Are the Consequences of Missed Doses?

For people with narcolepsy or OSA, excessive daytime sleepiness (EDS) isn't just inconvenient — it's a safety issue. Missing doses of Sunosi can result in dangerous sleepiness behind the wheel, impaired work performance, and reduced quality of life. Clinical studies showed that Sunosi was not associated with withdrawal symptoms upon sudden discontinuation, but the return of EDS symptoms can be abrupt and disruptive.

How Does Sunosi Compare to Easier-to-Find Alternatives?

Generic modafinil and generic armodafinil are much more widely available because they've been on the market for many years and are manufactured by multiple companies. Pitolisant (Wakix) is brand-only but is not a controlled substance. Sodium oxybate (Xyrem/Xywav) is a Schedule II medication with even stricter controls. If you're consistently unable to fill Sunosi, talk to your doctor about whether an alternative might work for you. Check out our guide on

Tips to Find Sunosi in Stock Near You

If you're struggling to fill your Sunosi prescription, here are steps that can help:

Use medfinder: medfinder calls pharmacies near you to check which ones actually have your medication in stock, so you don't have to spend hours on hold.

Try specialty or mail-order pharmacies: Large mail-order pharmacies (like CVS Caremark or Express Scripts) often have more reliable stock of brand-name controlled substances.

Contact your prescriber early: Don't wait until you run out. Contact your doctor's office 2–3 weeks before you need a refill to allow time to locate stock.

Ask about the free trial voucher: Axsome Therapeutics offers a one-time 30-day free trial for patients with a valid prescription, which can buy time while you secure ongoing supply.

Expand your search radius: Pharmacies just 10–15 miles away may have stock when your closest location doesn't.
