Leuprolide (Lupron Depot) has been hard to find since 2020. Learn why this critical medication is in short supply and what you can do about it in 2026.

If You're Struggling to Find Leuprolide, You're Not Alone

You've been prescribed Leuprolide — also sold as Lupron Depot, Eligard, or Fensolvi — and your pharmacy tells you it's out of stock. You call another pharmacy. Same answer. You start to worry, because this isn't a medication you can simply skip.

Whether you need Leuprolide for prostate cancer, endometriosis, uterine fibroids, or central precocious puberty, a gap in treatment can have real consequences. The good news: there are concrete steps you can take right now to find it. But first, let's understand what's going on.

What Is Leuprolide?

Leuprolide is a gonadotropin-releasing hormone (GnRH) agonist — a synthetic hormone that works by suppressing the body's production of testosterone and estrogen. It's administered as an injection, most commonly as a depot (long-acting) formulation given every one, three, four, or six months at a doctor's office.

Leuprolide is sold under several brand names:

  • Lupron Depot — the most widely prescribed brand, made by AbbVie
  • Eligard — a subcutaneous depot formulation
  • Fensolvi — a newer 6-month subcutaneous option
  • Camcevi — a 6-month subcutaneous emulsion
  • Lupron Depot-Ped — the pediatric formulation for precocious puberty

It's used to treat conditions where suppressing sex hormones is beneficial, including advanced prostate cancer, endometriosis, uterine fibroids, and central precocious puberty in children.

Why Is Leuprolide So Hard to Find?

The Leuprolide shortage isn't new — it's been an ongoing issue since 2020. Here are the main reasons it's still difficult to find in 2026:

1. Complex Manufacturing Process

Lupron Depot uses a specialized depot microsphere technology that slowly releases the drug over weeks or months. This formulation is significantly harder to manufacture than a simple liquid injection. The complex production process means there are very few facilities worldwide capable of making it, and any disruption — equipment failure, quality issues, or regulatory holds — can ripple through the supply chain for months.

2. Limited Number of Manufacturers

AbbVie is the primary manufacturer of Lupron Depot, and there is no FDA-approved generic version of the depot formulation in the United States. While generic leuprolide acetate exists as a daily injection (5mg/mL vial), the depot formulations that most patients rely on remain brand-only. This means there's no backup manufacturer to pick up the slack when AbbVie faces production challenges.

3. Supply Chain Fragility

The pharmaceutical supply chain for specialty injectable medications is inherently fragile. Raw material shortages, shipping delays, and distribution bottlenecks can all contribute to gaps in availability. Leuprolide's cold-chain storage requirements add another layer of complexity.

4. Increasing Demand

Demand for Leuprolide has grown as its uses have expanded. Beyond its original prostate cancer indication, it's now widely used for endometriosis, fibroids, gender-affirming care, and fertility treatments. More patients competing for a constrained supply means more frequent stockouts at individual pharmacies.

What You Can Do Right Now

If you can't find Leuprolide at your usual pharmacy, here are practical steps to take:

Use Medfinder to Check Real-Time Availability

Medfinder tracks pharmacy inventory in real time, so you can see which pharmacies near you actually have Leuprolide in stock — without spending hours on the phone.

Call Independent and Specialty Pharmacies

Large chain pharmacies often face the same supply issues simultaneously. Independent pharmacies and specialty pharmacies sometimes have access to different distribution channels and may have stock when the big chains don't.

Ask Your Doctor About Alternative Formulations

If you can't find the specific Lupron Depot strength you need, ask your provider whether a different formulation might work. For prostate cancer patients, alternatives like Eligard, Camcevi, or even Zoladex (Goserelin) may be options. For endometriosis, the oral GnRH antagonist Elagolix (Orilissa) may be considered.

Plan Ahead

If your next injection is due in a few weeks, start looking now rather than waiting until the last minute. Ask your doctor's office to order the medication in advance through their specialty distributor, which often has more reliable access than retail pharmacies.

Contact AbbVie Directly

AbbVie's support line can sometimes help locate available inventory or connect patients with specialty pharmacies that have stock. For Lupron Depot-Ped, call 1-855-LUPRON-P (1-855-587-7667).

What About Cost?

The Leuprolide shortage has also put pressure on prices. Brand-name Lupron Depot costs approximately $2,146 to $2,250 per monthly injection without insurance, and the 6-month formulation can exceed $13,000. If cost is a barrier on top of availability issues, check out our guide on how to save money on Leuprolide, including manufacturer copay cards and patient assistance programs.

Final Thoughts

The Leuprolide shortage is frustrating, but it's not hopeless. By using tools like Medfinder, working closely with your healthcare provider, and exploring alternative formulations and pharmacies, you can improve your chances of getting the medication you need without dangerous gaps in treatment.

Is there a generic version of Lupron Depot?

There is no FDA-approved generic version of the Lupron Depot (depot/long-acting) formulation in the US. Generic leuprolide acetate is only available as a daily subcutaneous injection (5mg/mL), which is not the same as the monthly or multi-month depot injections most patients use.

How long has the Leuprolide shortage been going on?

The Leuprolide shortage has been tracked by ASHP since 2020. While there have been periods of improvement, supply disruptions have continued intermittently through 2025 and into 2026, particularly for the 3.75mg, 11.25mg, and 22.5mg depot formulations.

Can I switch from Lupron Depot to Eligard if Lupron is unavailable?

Eligard contains the same active ingredient (leuprolide acetate) but is a subcutaneous injection rather than intramuscular. Your doctor may be able to switch you, but the dosing and administration are different. Eligard is primarily labeled for prostate cancer, so it may not be appropriate for all indications. Always consult your prescriber before switching.

What happens if I miss my Leuprolide injection due to a shortage?

Missing a scheduled Leuprolide injection can allow hormone levels to rise again, potentially worsening your condition. For prostate cancer patients, testosterone may rebound. For endometriosis patients, symptoms may return. Contact your doctor immediately if you're at risk of missing a dose — they can help find alternative sources or adjust your treatment plan.
