What Is Orgovyx? Uses, Dosage, and What You Need to Know in 2026

If you or someone you love has been prescribed Orgovyx (relugolix) for prostate cancer, you likely have a lot of questions. This comprehensive guide covers everything you need to know about Orgovyx as a patient: what it is, how it works, how to take it, what it costs, and what the research shows about its effectiveness.

What Is Orgovyx?

Orgovyx is the brand name for relugolix — a prescription medication approved by the FDA on December 18, 2020 for the treatment of adult patients with advanced prostate cancer. It is manufactured by Sumitomo Pharma America in partnership with Pfizer for U.S. commercialization.

Orgovyx belongs to a class of medications called GnRH (gonadotropin-releasing hormone) receptor antagonists. It is the first and only oral GnRH antagonist approved for prostate cancer in the United States. Before Orgovyx, all GnRH receptor antagonists required injections.

What Is Orgovyx Used For?

Orgovyx has one FDA-approved indication: the treatment of adult men with advanced prostate cancer. Specifically, it is used as part of androgen deprivation therapy (ADT) — a treatment approach that lowers testosterone to very low levels ("castrate levels") to slow or stop the growth of prostate cancer cells that depend on testosterone.

Orgovyx may be used in several prostate cancer settings, including:

Biochemical recurrence (rising PSA after surgery or radiation)

Newly diagnosed castration-sensitive metastatic prostate cancer

Advanced localized disease (locally advanced prostate cancer)

In combination with radiation therapy for high-risk or locally advanced disease

How Is Orgovyx Taken?

Orgovyx comes as a 120 mg film-coated tablet, light red in color and almond-shaped. Here's how it's taken:

Day 1 (Loading Dose): Take 3 tablets (360 mg) on the first day of treatment. This loading dose rapidly suppresses testosterone.

Day 2 onward: Take 1 tablet (120 mg) once daily, at approximately the same time each day.

With or without food: Orgovyx can be taken with or without food. Swallow tablets whole — do not crush, chew, or split.

Missed dose: Take it as soon as you remember. If more than 12 hours have passed, skip it and take your next dose at the regular time. Do not double up.

Interrupted treatment: If Orgovyx is stopped for more than 7 days and then restarted, the 360 mg loading dose must be repeated on the first day.

How Effective Is Orgovyx?

Orgovyx's effectiveness was established in the Phase 3 HERO trial, which enrolled 934 men with advanced prostate cancer. Key findings:

96.7% of Orgovyx patients maintained castrate testosterone levels (below 50 ng/dL) through 48 weeks, compared to 88.8% with leuprolide injections

56% of patients reached castrate levels by Day 4; 99% by Day 15

PSA levels dropped by 65% by Day 15 and by 83% by Day 29

54% lower incidence of major adverse cardiovascular events compared to leuprolide

55% of patients in a substudy returned to normal testosterone within 90 days after stopping treatment

Who Should NOT Take Orgovyx?

Orgovyx is contraindicated for people with:

Severe hypersensitivity (severe allergic reaction) to relugolix or any ingredient in the tablets

Use caution (discuss with your doctor) if you have:

Long QT syndrome or significant cardiovascular disease

Electrolyte abnormalities

Congestive heart failure

A female partner of reproductive potential (men must use contraception during treatment and for 2 weeks after stopping)
