Cresemba Coupons & Prices

Looking for a Cresemba coupon? Cresemba (isavuconazonium sulfate) is a brand-name triazole antifungal used to treat serious, invasive fungal infections, and because there is no generic version, the price can be high. On this page you can enter your ZIP code above to see today's cash price at pharmacies near you and use the Rx.com discount coupon, which can help whether you are uninsured, on Medicare, or paying out of pocket. Below we explain what Cresemba is, how the manufacturer savings card compares with an Rx.com cash coupon, and how it stacks up against related antifungal medicines.

What is Cresemba and how does it work?

Cresemba is the brand name for isavuconazonium sulfate, a prodrug that the body converts into isavuconazole, an azole (triazole) antifungal. It is FDA-approved to treat invasive aspergillosis and invasive mucormycosis in adults 18 years and older. These are serious fungal infections that most often affect people with weakened immune systems. Cresemba comes as oral capsules and as an intravenous (IV) injection given in a healthcare setting.

Azole antifungals like isavuconazole work by blocking the fungus from making ergosterol, a key building block of its cell membrane, which stops the fungus from growing. Doctors sometimes also use Cresemba off-label to help prevent or treat other invasive fungal infections in immunocompromised patients, such as those with blood cancers or who have had a transplant. Any use should be directed and monitored by your prescriber.

Cresemba cost: manufacturer savings card vs. Rx.com cash coupon

There is no generic version of Cresemba available yet, so the brand-name price is what you will typically see. Astellas, the maker of Cresemba, offers a manufacturer savings card through its official site at activatethecard.com/cresemba. Manufacturer copay cards like this are generally limited to people with commercial (private) insurance and cannot be used if you have Medicare, Medicaid, or other government coverage. Terms, eligibility, and any savings limits are set by the manufacturer and can change, so check the official page for current details.

If you are uninsured, covered by Medicare, or the manufacturer card is declined at the pharmacy, an Rx.com cash coupon is a helpful alternative. It is a discount coupon that anyone can use instead of insurance. To compare, enter your ZIP above to see today's cash price with the Rx.com coupon at pharmacies near you. Astellas also runs patient support programs; you can learn about access and assistance options through the manufacturer's access and support resources.

Cresemba alternatives and related antifungals

Cresemba is one of several azole antifungals used for invasive fungal infections. The best choice depends on the specific infection, other medicines you take, and your prescriber's judgment. Related medicines you may see or want to price-compare include:

• voriconazole and its brand Vfend
• posaconazole and its brand Noxafil
• itraconazole
• fluconazole

Several of these are available as generics, which is often the biggest lever for lowering cost. Do not switch antifungals on your own, as they differ in what infections they treat and how they interact with other drugs. Talk with your provider about the right option for you.

Cresemba safety and side effects

Cresemba does not carry a boxed warning, but there are important safety points to know. It can affect the liver, so your provider may check your liver function, and it is used with caution in people with liver problems. It can cause harm to an unborn baby, so it should be avoided in pregnancy and effective contraception is advised. It should not be used by people with a known hypersensitivity to azole antifungals, and infusion-related reactions can occur with the IV form. Cresemba has important drug interactions through a liver enzyme called CYP3A4 and should not be combined with strong CYP3A4 inhibitors (such as ketoconazole) or strong inducers (such as rifampin, carbamazepine, or St. John's wort). It is also contraindicated in people with familial short QT syndrome.

Common side effects include nausea, vomiting, diarrhea, headache, elevated liver tests, low potassium (hypokalemia), constipation, and swelling in the arms or legs (peripheral edema). This is not a complete list and is not medical advice. Tell your provider about all medicines you take and any reactions you notice, and follow their guidance.
