Can't find Lupron Depot? Learn about real alternatives like Eligard, Zoladex, Trelstar, and Orgovyx that your doctor may prescribe instead.

When Lupron Isn't Available, You Still Have Options

If you or your doctor has been unable to find Lupron Depot in stock, you may be wondering: are there other medications that do the same thing? The short answer is yes — there are several alternatives that work through similar mechanisms and treat many of the same conditions.

That said, switching medications is a decision that should always be made with your healthcare provider. Different drugs have different formulations, dosing schedules, and insurance coverage. This guide will walk you through the most common alternatives so you can have an informed conversation with your doctor.

What Is Lupron and How Does It Work?

Lupron Depot (Leuprolide Acetate) is a GnRH (gonadotropin-releasing hormone) agonist manufactured by AbbVie. It's given as an intramuscular injection at intervals ranging from 1 to 6 months.

Here's how it works: GnRH agonists initially stimulate the pituitary gland to release hormones, but with continuous use, they actually shut down hormone production. This leads to dramatically reduced levels of testosterone (in men) or estrogen (in women). The result is a state of medical hormone suppression that's critical for treating conditions like:

  • Advanced prostate cancer — Reducing testosterone slows cancer growth
  • Endometriosis — Lowering estrogen shrinks endometrial tissue and reduces pain
  • Uterine fibroids — Estrogen suppression shrinks fibroids before surgery
  • Central precocious puberty — Pauses early puberty in children

For more detail, read our full guide on how Lupron works.

Alternative 1: Eligard (Leuprolide Acetate — Subcutaneous)

Eligard contains the exact same active ingredient as Lupron Depot — Leuprolide Acetate. The key difference is the delivery method: Eligard is injected subcutaneously (under the skin) rather than intramuscularly (into the muscle).

What it's approved for: Advanced prostate cancer

Available formulations:

  • 7.5 mg (1-month)
  • 22.5 mg (3-month)
  • 30 mg (4-month)
  • 45 mg (6-month)

Why it might work for you: Since Eligard uses the same drug, the therapeutic effect is essentially identical for prostate cancer patients. It may be easier to find because it's manufactured by a different company (Tolmar). However, Eligard is only approved for prostate cancer — it doesn't have FDA approval for endometriosis or fibroids.

Key consideration: Your doctor needs to write a new prescription. Lupron Depot and Eligard are not automatically interchangeable.

Alternative 2: Zoladex (Goserelin Acetate)

Zoladex is another GnRH agonist, but it uses a different active ingredient — Goserelin. It's delivered as a small implant injected under the skin of the abdomen.

What it's approved for:

  • Advanced prostate cancer
  • Breast cancer (premenopausal, hormone receptor-positive)
  • Endometriosis
  • Endometrial thinning before ablation surgery

Available formulations:

  • 3.6 mg implant (1-month)
  • 10.8 mg implant (3-month)

Why it might work for you: Zoladex has a broader range of approved indications than Eligard, making it a potential option for both cancer patients and women with endometriosis. It's manufactured by AstraZeneca, providing a different supply chain than AbbVie's Lupron.

Key consideration: While the mechanism is similar, Goserelin and Leuprolide are different drugs. Some patients may experience different side effect profiles.

Alternative 3: Trelstar (Triptorelin Pamoate)

Trelstar is a GnRH agonist that uses the active ingredient Triptorelin. It's given as an intramuscular injection, similar to Lupron Depot.

What it's approved for: Advanced prostate cancer

Available formulations:

  • 3.75 mg (1-month)
  • 11.25 mg (3-month)
  • 22.5 mg (6-month)

Why it might work for you: Trelstar is a direct alternative for prostate cancer patients and works through the same GnRH agonist mechanism. It's manufactured by Verity Pharmaceuticals/Debiopharm, offering yet another supply source independent of AbbVie.

Key consideration: Like Eligard, Trelstar is only approved for prostate cancer in the U.S. and wouldn't be a first-line alternative for endometriosis or fibroids.

Alternative 4: Orgovyx (Relugolix)

Orgovyx is a newer medication that represents a different approach. Instead of being a GnRH agonist, it's a GnRH antagonist — and it comes as a daily oral tablet. No injections required.

What it's approved for: Advanced prostate cancer

How it works: Unlike GnRH agonists that initially spike hormone levels before suppressing them (the "tumor flare" effect), GnRH antagonists like Orgovyx directly block GnRH receptors from the start. This means faster testosterone suppression without the initial flare.

Dosing: 360 mg loading dose on day 1, then 120 mg once daily

Why it might work for you: Orgovyx is ideal for prostate cancer patients who want to avoid injections entirely or who experience supply issues with injectable GnRH agonists. It also allows for faster testosterone recovery after stopping treatment. Studies suggest it may carry lower cardiovascular risk than injectable GnRH agonists.

Key consideration: Orgovyx requires daily pill-taking. It's generally more expensive than Lupron Depot on a monthly basis, and insurance coverage varies. It is not approved for endometriosis, fibroids, or CPP.

What About Patients With Endometriosis or Fibroids?

If you're being treated for endometriosis or uterine fibroids and can't find Lupron Depot, your options are somewhat different:

  • Zoladex is the closest alternative with FDA approval for endometriosis
  • Orilissa (Elagolix) — an oral GnRH antagonist specifically approved for endometriosis pain, also made by AbbVie
  • Myfembree (Relugolix/estradiol/norethindrone) — an oral combination approved for uterine fibroids and endometriosis

Talk to your gynecologist about which option makes the most sense for your specific situation.

Final Thoughts

Not being able to find Lupron is stressful, but you have real alternatives. The right choice depends on your specific condition, insurance coverage, and personal preferences.

Before making any changes, talk to your prescribing doctor. They can help you weigh the options and handle the insurance paperwork for a switch.

In the meantime, you can use Medfinder to check if Lupron Depot is available near you. And for the latest on supply issues, read our Lupron shortage update for 2026.

What is the closest alternative to Lupron Depot?

Eligard is the closest alternative because it contains the exact same active ingredient (Leuprolide Acetate) but is delivered subcutaneously instead of intramuscularly. However, Eligard is only FDA-approved for prostate cancer. For endometriosis, Zoladex (Goserelin) is the nearest alternative with FDA approval.

Can I switch from Lupron to an oral medication?

For prostate cancer, Orgovyx (Relugolix) is an oral GnRH antagonist that doesn't require injections. For endometriosis, Orilissa (Elagolix) is an oral option. For uterine fibroids, Myfembree is available as an oral tablet. Your doctor can determine if an oral option is appropriate for your condition.

Is Eligard the same as Lupron?

Eligard and Lupron Depot both contain Leuprolide Acetate and work through the same mechanism. However, they use different delivery systems — Lupron Depot is an intramuscular injection and Eligard is subcutaneous. They are not automatically interchangeable and require separate prescriptions. Eligard is only approved for prostate cancer.

Will my insurance cover a Lupron alternative?

Most insurance plans cover GnRH agonists, but coverage and prior authorization requirements vary by drug and plan. If you're switching due to a shortage, your doctor's office can often expedite a new prior authorization. Ask your insurance company about their preferred alternatives — some plans may actually prefer Eligard or Zoladex over Lupron Depot.
