If you are eligible to receive your Sustol prescription through the patient assistance program, your medication will be free. We charge a flat monthly service fee of $49 per medication to cover the cost of our services.

Am I eligible for Sustol patient assistance?

To be eligible for the Sustol patient assistance program, you will need to meet specific eligibility criteria set by the pharmaceutical company. At NiceRx, we review each Sustol enrollment application individually. The main factors considered are:

  • I am a permanent, legal resident of the United States or Puerto Rico
  • I am uninsured or my insurance doesn’t cover my medication
  • I meet certain income eligibility requirements

How do I apply for the Sustol patient assistance program?

Applying for the Sustol patient assistance program through NiceRx is simple. Begin by completing the enrollment application on our website. We will ask for details about your healthcare provider, your insurance plan, and your household income. This information is required by the pharmaceutical manufacturers that supply your medication. We may be able to help you access patient assistance for other medications as well as Sustol, so please tell us about any medications that you have been prescribed.

If we determine that you may be eligible for Sustol assistance, we will handle the full enrollment process on your behalf. We will work with your healthcare provider to prepare and submit all the documents required for you to enroll. If you are successfully enrolled in the Sustol patient assistance program, we will also request your Sustol medication refills on your behalf for up to 1 year. At the end of your enrollment period, we will contact you for updated details and seek to re-enroll you in the program.

Is NiceRx a Sustol coupon provider?

NiceRx does not provide Sustol coupons, discount cards or copay cards. We do not offer printable Sustol manufacturer coupons, Sustol discounts, rebates, Sustol savings cards, trial offers, or free samples.

What is Sustol?

Sustol (granisetron extended-release injection) is an FDA (U.S. Food and Drug Administration) approved medication manufactured by Heron Therapeutics, Inc. Sustol is a serotonin-3 (5-HT3) receptor antagonist indicated in combination with other antiemetics in adults for the prevention of acute and delayed chemotherapy-induced nausea and vomiting associated with initial and repeat courses of moderately emetogenic chemotherapy (MEC) such as cisplatin, or anthracycline and cyclophosphamide (AC) combination chemotherapy regimens.

What doses of Sustol are available?

Sustol is available as an extended-release Injection, in the following doses: 10 mg/0.4 mL in a single-dose, pre-filled syringe.

The recommended dosage in adults is 10 mg as a single subcutaneous injection at least 30 minutes before the start of emetogenic chemotherapy on Day 1. Do not administer more frequently than once every 7 days. Use for more than 6 months is not recommended. In patients with moderate renal impairment administer not more frequently than once every 14 days. Sustol is not recommended in patients with severe renal impairment.
