Learn why Nadolol is so hard to find in 2026. We explain the shortage causes, supply chain issues, and what you can do to get your prescription filled.
If you've been calling pharmacy after pharmacy trying to fill your Nadolol prescription, you're not imagining things. Many patients across the country are struggling to find this medication in stock, and the frustration is real. Whether you take Nadolol for high blood pressure, angina, or another condition, not being able to fill your prescription can feel stressful and even scary.
In this post, we'll explain what Nadolol is, why it's become difficult to find, and — most importantly — what you can do about it.
Nadolol (brand name Corgard) is a non-selective beta-blocker used to treat high blood pressure (hypertension) and chest pain (angina pectoris). It works by blocking the effects of adrenaline on your heart and blood vessels, which helps lower your heart rate, reduce blood pressure, and ease the workload on your heart.
Nadolol is unique among beta-blockers because it has a long half-life of 20 to 24 hours, which means most patients only need to take it once a day. It's also less likely to cause certain central nervous system side effects (like vivid dreams or depression) compared to other beta-blockers such as Propranolol, because it doesn't cross the blood-brain barrier as easily.
Nadolol comes in tablet form in strengths of 20 mg, 40 mg, 80 mg, and 160 mg. It is available as a generic, and the brand-name version Corgard is largely discontinued.
Over the past several years, the number of companies making generic Nadolol has decreased. When only a small number of manufacturers produce a medication, any disruption at one facility can create a ripple effect across the entire supply. Currently, companies like Amneal Pharmaceuticals and Greenstone LLC produce generic Nadolol, but the limited supplier base makes the market fragile.
Like many generic medications, Nadolol relies on active pharmaceutical ingredients (APIs) that are sourced from overseas. Global supply chain disruptions — from shipping delays to manufacturing slowdowns — have affected the availability of raw materials needed to produce Nadolol tablets.
Nadolol has experienced periodic shortages since 2019. Certain strengths, particularly the 80 mg tablet, have been harder to find than others. These shortages tend to come and go, which makes it unpredictable for patients and pharmacies alike.
Generic beta-blockers like Nadolol are inexpensive medications, which means the profit margins for manufacturers are slim. When production costs rise or demand fluctuates, some manufacturers may prioritize higher-profit drugs, leading to reduced Nadolol output.
Tools like Medfinder can help you search for pharmacies near you that currently have Nadolol in stock. Instead of calling dozens of pharmacies, you can check availability online in seconds.
Big chain pharmacies often run out of medications faster because they serve more patients. Independent pharmacies and compounding pharmacies sometimes have better luck sourcing drugs that are in short supply. It's worth calling a few local independents in your area.
If Nadolol remains unavailable, your doctor may be able to switch you to a similar beta-blocker. Options like Propranolol, Atenolol, Metoprolol, or Bisoprolol work in similar ways and may be easier to find. Learn more in our post on alternatives to Nadolol.
This is critical: never stop taking Nadolol abruptly without your doctor's guidance. Suddenly stopping a beta-blocker can cause rebound effects including worsening chest pain, heart attack, or irregular heartbeat. If you're running low and can't find a refill, contact your prescriber right away so they can help you taper safely or switch medications.
Here are a few proactive steps you can take:
Finding Nadolol in 2026 can be a challenge, but you're not without options. By understanding the reasons behind the shortage and taking proactive steps — like using Medfinder, trying independent pharmacies, and staying in close contact with your doctor — you can keep your treatment on track.
