Isavuconazole belongs to the class of medications called antifungals. It is used for people 18 years of age and older to treat certain types of invasive (inside the body) fungal infections, specifically those caused by Aspergillus or Mucormycosis fungi.

Cresemba works by killing or stopping the growth of these types of fungi.

Cresemba may be available under multiple brand names and/or in several different forms. Any specific brand name of Cresemba may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of Cresemba may not be used for all of the conditions discussed here.

Your doctor may have suggested Cresemba for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking Cresemba, speak to your doctor. Do not stop taking Cresemba without consulting your doctor.

Do not give Cresemba to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take Cresemba if their doctor has not prescribed it.



Isavuconazole may be taken by mouth or given by intravenous (into a vein) injection.

The usual starting dose of Cresemba is 200 mg taken by mouth every 8 hours for 2 days (6 doses). After the first 6 doses, the usual dose is 200 mg taken once a day.

Capsules may be taken with food or on an empty stomach. They should be swallowed whole. Do not chew, crush, dissolve, or open the capsules.

Finish all Cresemba, even if you have started to feel better.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

It is important to take Cresemba exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store Cresemba at room temperature, protect it from light and moisture, and keep it out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

  • stop taking one of the medications,
  • change one of the medications to another,
  • change how you are taking one or both of the medications, or

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Medications other than those listed above may interact with Cresemba. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the Nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.



Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health.

Certain medications (e.g., Sotalol, quinidine, thioridazine, Chlorpromazine, Pimozide, moxifloxacin, Mefloquine, pentamidine, arsenic trioxide, probucol, Tacrolimus) can increase the risk of a type of abnormal heart rhythm called QT prolongation, and should not be used in combination with isavuconazole. You are more at risk for this type of abnormal heart rhythm and its complications if you:

  • are female
  • are older than 65 years of age
  • have a family history of sudden cardiac death
  • have a history of heart disease or abnormal heart rhythms
  • have a slow heart rate
  • have congenital QT prolongation
  • have Diabetes
  • have had a Stroke
  • have low potassium, magnesium, or calcium levels
  • have nutritional deficiencies

If you have heart disease and abnormal heart rhythms, or are taking certain medications, discuss with your doctor how Cresemba may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Cresemba, and whether any special monitoring is needed.

Drowsiness/reduced alertness: Isavuconazole may cause confusion, drowsiness, or dizziness, affecting your ability to drive or operate machinery. Avoid driving, operating machinery, or performing other potentially hazardous tasks until you have determined how you are affected by Cresemba.

Infusion related problems: You may experience reactions during the infusion of the intravenous formulation of isavuconazole. These can include Low Blood Pressure causing dizziness or feeling faint, tingling sensations, difficulty breathing, nausea, and headache. If you have a reaction during your infusion, tell your doctor, as the infusion may have to be stopped.

Liver function:  Isavuconazole may affect liver function. If you have liver problems, discuss with your doctor how Cresemba may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Cresemba, and whether any special monitoring is needed. Your doctor may want to test your liver function regularly with blood tests while you are taking Cresemba.

Skin reactions: In rare cases, people have had skin reactions when they have taken Cresemba. If you get a skin rash that worsens, or if you experience skin conditions such as peeling, shedding, or scaling of the skin, or any other unusual skin reaction, contact your doctor immediately.
