Hycamtin Shortage Update: What Patients Need to Know in 2026

If you've been prescribed Hycamtin (topotecan) and are worried about shortages, you're right to stay informed. Hycamtin has had supply challenges in the past, and oncology drugs in general are frequently affected by manufacturing disruptions, supply chain issues, and demand surges. Here is the most current information available for 2026, along with what you should do if you're having trouble filling your prescription.

Current Hycamtin Availability in 2026

As of early 2026, there is no active nationwide FDA-listed shortage of topotecan. Generic topotecan intravenous vials (4 mg) are available from multiple manufacturers, including companies like Mylan, Teva, and Sun Pharmaceutical. The IV formulation administered in infusion centers is generally accessible through hospital pharmacies and specialty pharmacy distribution channels.

However, the oral capsule formulation — 0.25 mg and 1 mg capsules that patients take at home for SCLC — may be more difficult to find at retail pharmacies. This is not necessarily a national shortage; it reflects the fact that oral Hycamtin is a specialty medication stocked only at specialty pharmacies, not general retail chains. Individual patients can still experience difficulty accessing it depending on their insurance, location, and which specialty pharmacy their plan works with.

A History of Hycamtin Supply Challenges

Hycamtin has not been immune to supply disruptions. In March 2017, Novartis experienced a shortage of Hycamtin oral capsules in both the 0.25 mg and 1 mg strengths. The American Society of Health-System Pharmacists (ASHP) listed this shortage, and Novartis did not provide a public reason for the disruption. The shortage was ultimately resolved in October 2017 when Novartis made capsules available with new National Drug Codes (NDCs).

More broadly, oncology drug shortages are an ongoing concern in the United States. According to the FDA, there were approximately 270 drugs in shortage as of March 2025, with roughly 8% being chemotherapy agents. Shortages of cancer drugs are particularly serious because treatment delays can directly affect patient outcomes.

Why Do Oncology Drug Shortages Happen?

Understanding why shortages happen can help you prepare and respond faster. The main causes include:

Manufacturing quality issues — Problems at a manufacturing facility can cause production halts

Limited-source dependency — Some drugs are made by only one or two manufacturers, making the supply fragile

Active pharmaceutical ingredient (API) shortages — The raw material to make the drug may become scarce

Low profit margins — Older generic chemotherapy drugs often have thin margins, reducing incentive to maintain large buffer stocks

Demand surges — A sudden increase in patients needing a drug can outpace supply

How to Check If There Is a Current Hycamtin Shortage

The most authoritative sources for drug shortage information include:

FDA Drug Shortage Database — updated regularly by the FDA

ASHP Drug Shortage Resource Center — maintained by the American Society of Health-System Pharmacists

Your oncologist's office — oncology practices are often the first to know about supply disruptions affecting their patients

What to Do If You Can't Find Hycamtin

If you're having trouble filling a Hycamtin prescription — whether due to a shortage or simply because it's hard to find at retail pharmacies — here are your immediate action steps:

Call your oncologist's office — They can often source chemotherapy through clinical channels not available to retail pharmacies.

Ask for generic topotecan — Generic versions from multiple manufacturers may be available even if brand-name Hycamtin is not.

Use medfinder — medfinder calls pharmacies near you to find which ones have topotecan in stock and can fill your specific prescription.

Discuss alternative therapy — If topotecan is genuinely unavailable, your oncologist can discuss whether lurbinectedin (Zepzelca), irinotecan, or another regimen is appropriate.

Don't Panic — Act Quickly

Even when shortages occur, oncology teams have experience managing them. Speak to your care team early and often, and don't wait until you've run out to start problem-solving. For more information, read our guide on alternatives to Hycamtin if your prescription can't be filled.
