Alternatives to Leuprolide if You Can't Fill Your Prescription

When Leuprolide Is Unavailable, What Are Your Options?

If you've been trying to fill your Leuprolide prescription and keep hitting dead ends, you're not alone. The ongoing Leuprolide shortage has left many patients scrambling — and wondering whether there's something else that could work.

The answer, in most cases, is yes. There are several medications in the same drug class or with similar effects that your doctor may consider. But switching medications isn't something to do on your own — it requires a conversation with your prescriber about your specific condition, treatment history, and what's available.

Here's what you need to know about the alternatives.

What Is Leuprolide and How Does It Work?

Leuprolide (brand names Lupron Depot, Eligard, Fensolvi, Camcevi) is a gonadotropin-releasing hormone (GnRH) agonist. It works by continuously stimulating GnRH receptors in the pituitary gland, which — counterintuitively — causes the pituitary to stop producing luteinizing hormone (LH) and follicle-stimulating hormone (FSH) after an initial surge.

The result: testosterone drops to castrate levels in men, and estrogen drops to postmenopausal levels in women. This makes it effective for hormone-sensitive conditions like prostate cancer, endometriosis, uterine fibroids, and central precocious puberty.

For a full overview, see our guide on what Leuprolide is and how it's used.

Alternative 1: Goserelin (Zoladex)

Drug class: GnRH agonist

How it's given: Subcutaneous implant injected into the abdominal wall every 1 month (3.6mg) or every 3 months (10.8mg).

Approved for: Advanced prostate cancer, breast cancer, endometriosis, and endometrial thinning before surgery.

Key differences from Leuprolide: Goserelin uses a small solid implant (about the size of a grain of rice) rather than a liquid depot injection. It's administered subcutaneously rather than intramuscularly. Some studies suggest Goserelin may be slightly better at maintaining consistently low testosterone levels compared to Leuprolide.

Availability: Goserelin (Zoladex) is manufactured by AstraZeneca and has generally maintained more stable supply than Lupron Depot. It may be a good option if Leuprolide is unavailable.

Alternative 2: Triptorelin (Trelstar, Triptodur)

Drug class: GnRH agonist

How it's given: Intramuscular injection every 1 month (3.75mg), every 3 months (11.25mg), or every 6 months (22.5mg). Triptodur is a 6-month formulation specifically for central precocious puberty.

Approved for: Advanced prostate cancer and central precocious puberty.

Key differences from Leuprolide: Triptorelin works through the same mechanism as Leuprolide and is given as a similar depot injection. It's considered clinically equivalent for prostate cancer treatment. Triptodur offers a 6-month option for pediatric patients with CPP, which can be an important alternative when Lupron Depot-Ped is unavailable.

Availability: Manufactured by Verity Pharmaceuticals (Trelstar) and Arbor Pharmaceuticals (Triptodur), these products have different supply chains than Lupron Depot, so they may be available when Lupron is not.

Alternative 3: Degarelix (Firmagon)

Drug class: GnRH antagonist (not an agonist)

How it's given: Subcutaneous injection. Initial dose: two 120mg injections, then 80mg monthly.

Approved for: Advanced prostate cancer.

Key differences from Leuprolide: This is an important distinction — Degarelix is a GnRH antagonist, not an agonist. It blocks GnRH receptors directly rather than overstimulating them. The major clinical advantage is that Degarelix does not cause the initial testosterone flare that occurs with GnRH agonists like Leuprolide. This makes it particularly useful for patients with symptomatic metastatic disease where a flare could be dangerous (spinal cord compression, urinary obstruction).

Limitation: Only approved for prostate cancer, and requires monthly injections (no 3-month or 6-month option). The injection can cause injection-site reactions more frequently than Leuprolide.

Alternative 4: Relugolix (Orgovyx)

Drug class: GnRH antagonist (oral)

How it's taken: One tablet by mouth daily (120mg after a 360mg loading dose on day 1).

Approved for: Advanced prostate cancer.

Key differences from Leuprolide: Relugolix is the first and only oral GnRH antagonist approved for prostate cancer. No injections required. Like Degarelix, it does not cause a testosterone flare. In clinical trials, it achieved castrate testosterone levels faster than Leuprolide and showed a lower rate of cardiovascular events. Testosterone recovery after stopping treatment is also faster.

Limitation: Currently only FDA-approved for prostate cancer. Must be taken daily (compared to monthly or less frequent injections with depot formulations). May interact with certain medications including P-glycoprotein inhibitors.

Other Options by Condition

For Endometriosis

• Elagolix (Orilissa) — An oral GnRH antagonist specifically approved for endometriosis. Not affected by the Lupron shortage. Taken as a daily pill.
• Goserelin (Zoladex) — Approved for endometriosis and may be available when Lupron Depot is not.
• Norethindrone acetate — A progestin-only option for endometriosis that doesn't suppress hormones as aggressively.

For Central Precocious Puberty

• Triptorelin (Triptodur) — A 6-month intramuscular injection for CPP.
• Histrelin (Supprelin LA) — A subcutaneous implant that provides 12 months of GnRH suppression. Surgically implanted in the upper arm.

Important: Don't Switch on Your Own

While all of these medications work to suppress sex hormones, they are not interchangeable without medical supervision. Doses, administration routes, monitoring requirements, and insurance coverage vary. Your doctor needs to evaluate:

• Your specific diagnosis and treatment goals
• How well you've responded to Leuprolide
• Any contraindications to the alternative medication
• Insurance coverage and prior authorization requirements

Final Thoughts

If you can't find Leuprolide, don't panic — but don't delay either. Talk to your doctor about the alternatives listed above, and use Medfinder to check whether Leuprolide or its alternatives are in stock near you. The most important thing is that you don't go without treatment.
