Alternatives to Chorionic Gonadotropin If You Can't Fill Your Prescription

When Your Prescription Can't Be Filled

You have a prescription for Chorionic Gonadotropin, and your pharmacy says they can't fill it. Maybe it's on backorder. Maybe they don't carry it at all. Either way, you need treatment — and you need to know what your options are.

The ongoing Chorionic Gonadotropin shortage has pushed many patients and providers to explore alternatives. The right substitute depends on your specific condition and why you were prescribed HCG in the first place. This guide covers the most common alternatives so you can have an informed conversation with your doctor.

What Is Chorionic Gonadotropin and How Does It Work?

Chorionic Gonadotropin — commonly called HCG — is an injectable hormone medication in the gonadotropin class. It mimics luteinizing hormone (LH), a key reproductive hormone.

In women, HCG triggers the final maturation and release of eggs from the ovaries (ovulation). This is why it's often called the "trigger shot" in fertility treatments like IVF and intrauterine insemination (IUI).

In men, HCG stimulates the Leydig cells in the testes to produce testosterone. It's commonly used alongside testosterone replacement therapy (TRT) to maintain testicular size and preserve fertility.

In boys with cryptorchidism (undescended testicles), HCG can promote testicular descent by stimulating testosterone production.

FDA-approved brands include Pregnyl, Novarel, and Ovidrel (the recombinant version). To learn more about the medication, see our guide on what Chorionic Gonadotropin is, its uses, and dosage.

Alternative 1: Ovidrel (Choriogonadotropin Alfa)

If you were prescribed urinary-derived HCG (Pregnyl or Novarel) and can't find it, Ovidrel is often the most direct substitute.

What It Is

Ovidrel contains Choriogonadotropin Alfa, a recombinant (lab-made) form of HCG manufactured by EMD Serono. Unlike Pregnyl and Novarel, which are derived from the urine of pregnant women, Ovidrel is produced using DNA technology, which gives it more consistent potency from batch to batch.

How It's Used

Ovidrel comes as a prefilled syringe (250 mcg/0.5 mL) for subcutaneous injection. It's primarily used as a trigger shot to induce ovulation during fertility treatment. The subcutaneous route makes self-injection easier for many patients.

Pros

• Prefilled syringe — no mixing or reconstitution required
• Subcutaneous injection (often more comfortable than intramuscular)
• More consistent potency due to recombinant manufacturing
• May have better availability than urinary-derived HCG

Cons

• Only available as a brand-name product (no generic)
• Typically more expensive — cash price ranges from $200 to $400+
• Primarily indicated for ovulation triggering; less commonly used for male hypogonadism

Who It's Best For

Women undergoing fertility treatment who need a trigger shot and can't find Pregnyl or Novarel. Talk to your reproductive endocrinologist about switching.

Alternative 2: Lupron Trigger (Leuprolide Acetate)

For patients in IVF cycles, a Lupron trigger is an increasingly popular alternative to an HCG trigger shot.

What It Is

Leuprolide Acetate (brand name Lupron) is a GnRH agonist. When given as a single dose at the right time in a fertility cycle, it causes a surge of natural LH from the pituitary gland, which triggers ovulation — similar to what HCG does.

How It's Used

Lupron trigger is given as a subcutaneous injection, typically 1–2 mg, timed 36 hours before egg retrieval. It's important to note that this only works if you haven't been using a GnRH agonist for suppression earlier in your cycle (it's most commonly used in antagonist protocols).

Pros

• Significantly reduces the risk of ovarian hyperstimulation syndrome (OHSS)
• Often more readily available than HCG products
• May be less expensive

Cons

• Only works in GnRH antagonist IVF protocols
• May require progesterone supplementation afterward
• Not a replacement for HCG in non-fertility uses (hypogonadism, cryptorchidism)

Who It's Best For

IVF patients at high risk for OHSS, or anyone in an antagonist protocol who can't find HCG.

Alternative 3: Clomiphene Citrate (Clomid)

While not a gonadotropin, Clomiphene Citrate (brand name Clomid) can be an alternative for some patients who were taking HCG.

What It Is

Clomiphene is a selective estrogen receptor modulator (SERM) that stimulates the pituitary gland to release more FSH and LH, which in turn promotes ovulation in women or increases testosterone production in men.

How It's Used

Clomiphene is taken as an oral tablet — no injections needed. For ovulation induction, the typical dose is 50–100 mg daily for 5 days. For men with hypogonadism, off-label doses typically range from 25–50 mg daily or every other day.

Pros

• Oral medication — no injections required
• Widely available and affordable (generic Clomiphene costs $10–$30 per cycle)
• Well-established safety profile

Cons

• Not a direct HCG replacement — different mechanism of action
• Cannot be used as an IVF trigger shot
• May cause side effects like hot flashes, mood changes, and visual disturbances
• Off-label for male use

Who It's Best For

Men looking for an alternative to HCG for testosterone support, or women with mild ovulatory dysfunction who don't require injectable gonadotropins.

Alternative 4: Menotropins (Menopur)

Menotropins (brand name Menopur) is another gonadotropin used in fertility treatment. It contains both follicle-stimulating hormone (FSH) and luteinizing hormone (LH) activity.

What It Is

Menopur is a purified preparation of gonadotropins derived from the urine of postmenopausal women. It's manufactured by Ferring Pharmaceuticals.

How It's Used

Menopur is injected subcutaneously or intramuscularly as part of ovarian stimulation protocols. It's used alongside HCG, not typically as a direct replacement for the trigger shot itself.

Who It's Best For

Patients whose fertility protocol requires gonadotropin stimulation. Menopur is part of the treatment pathway, not a standalone alternative to the HCG trigger.

Important: Always Talk to Your Doctor First

None of these alternatives should be started without your prescriber's guidance. The right substitute depends on:

• Your specific diagnosis (infertility, hypogonadism, cryptorchidism)
• Where you are in your treatment cycle
• Your medical history and risk factors
• What's actually available at pharmacies near you

Your doctor can also help you search for Chorionic Gonadotropin at different pharmacies. Tools like Medfinder can show real-time availability at pharmacies in your area, which may help you find the original medication before switching.

Final Thoughts

Not being able to fill your Chorionic Gonadotropin prescription is stressful, especially when you're in the middle of fertility treatment or managing a chronic condition. But you do have options.

Ovidrel is the closest direct substitute for most fertility uses. Lupron trigger is a strong option for IVF patients. Clomiphene offers an oral alternative for certain cases. And the original medication may still be available at a pharmacy you haven't tried yet — check our tips for finding it in stock.

The key is to act quickly, stay in close contact with your healthcare team, and know that alternatives exist. For a deeper dive into how HCG works, read our article on Chorionic Gonadotropin's mechanism of action.
