Rivastigmine Shortage Update: What Patients Need to Know in 2026

If you've had trouble filling your rivastigmine prescription recently, you may be wondering whether there's an official shortage. Here's the current status, the history of availability issues, and exactly what you can do if you're struggling to find this medication.

Current Rivastigmine Shortage Status (2026)

As of 2026, rivastigmine is not listed on the FDA's official Drug Shortage Database. Generic rivastigmine is manufactured by multiple companies, which generally provides supply resilience. However, that doesn't mean every patient can easily fill their prescription — localized shortages, stock gaps at individual pharmacies, and transitions between manufacturers can still cause real-world availability problems.

The Brand-Name Exelon Capsule Was Discontinued

One important change that has caused confusion: the brand-name Exelon oral capsule has been discontinued. Only generic rivastigmine capsules are now available. If your pharmacy used to fill the brand Exelon capsule and is now unclear about which generic to stock, that can look like a shortage — but it's really a transition issue. The Exelon Patch (brand transdermal) is still available, alongside multiple generic patch products.

Why Individual Pharmacies May Be Out of Stock

Even without a national shortage, patients frequently report difficulty finding specific rivastigmine strengths at their local pharmacy. The most common reasons:

Manufacturer supplier variability. With multiple generic manufacturers, your pharmacy's supplier may change, causing brief gaps.

Low stocking volume. Smaller pharmacies may keep minimal inventory of rivastigmine because it's a specialty dementia drug.

Patch strengths. The 4.6 mg/24h and 13.3 mg/24h patch strengths are less commonly stocked than the 9.5 mg/24h maintenance dose.

Growing demand. As the U.S. population ages, demand for all Alzheimer's medications is rising steadily.

History of Rivastigmine Availability Issues

Rivastigmine has not experienced the kind of dramatic national shortage seen with drugs like Adderall or GLP-1 medications. However, individual strength and formulation gaps have been documented over the years, particularly as the market shifted from brand-name to generic products. The discontinuation of the brand Exelon capsule was the most significant supply-side change in recent years.

What Patients Should Do Right Now

If you're having trouble finding rivastigmine, here's a practical action plan:

Don't wait until you run out. Start looking for your next refill at least 7–10 days before you run out.

Use medfinder. medfinder.com calls pharmacies near you on your behalf to find which ones have your medication in stock.

Call your doctor. If you've missed doses, don't restart without guidance — you may need to retitrate.

Ask about a different formulation. If one strength or form is unavailable, another may be in stock. For example, if the 9.5 mg/24h patch is out, ask if a different patch strength can be temporarily prescribed.

Consider mail-order. Mail-order pharmacies maintain larger inventories and are less subject to local stock variability. A 90-day supply through your insurance's mail-order option can provide peace of mind.

Ask about alternatives. If rivastigmine truly cannot be found, talk to your doctor about donepezil (Aricept) or another approved dementia medication as a substitute.

How to Monitor FDA Shortage Status

You can check the FDA's official drug shortage database at fda.gov/drugs/drug-safety-and-availability/drug-shortages. Search for "rivastigmine" to see if any new shortages are reported. The American Society of Health-System Pharmacists (ASHP) also maintains a shortage database at ashp.org/drug-shortages.

Bottom Line

Rivastigmine is not in an active FDA-declared national shortage as of 2026. However, localized pharmacy stock gaps are real and can disrupt treatment. Proactive planning — including early refills, pharmacy searching, and mail-order setups — is your best defense.
