Assessment ⬆ ⬇

Assess for signs and symptoms of infection (elevated WBC, fever, rhonchi/congestion, cough/sputum) before and periodically during therapy.
Obtain specimens for culture before instituting therapy. Therapy may be started before results are obtained.
Assess for signs and symptoms of hypersensitivity reactions (fever, malaise, fatigue, muscle or joint aches, skin pain or rash, blisters, peeling, oral lesions, conjunctivitis). Discontinue therapy and provide supportive care.
Assess for signs and symptoms of HF and/or left ventricular dysfunction (dyspnea, rales, peripheral edema, weight gain). If signs and/or symptoms of HF occur, discontinue therapy.
Monitor for signs and symptoms of hepatic impairment (abnormal LFTs, jaundice, fatigue, dark urine, pale stools) or pancreatitis (abdominal pain, nausea, vomiting); discontinue if severe and provide supportive care.
Monitor for symptoms of peripheral neuropathy (numbness/tingling in hands and feet) or hearing loss. If symptoms develop, discontinue therapy.

Lab Test Considerations:

Verify negative pregnancy test before starting therapy.
Monitor LFTs and bilirubin before and periodically during therapy, especially in patients with pre-existing hepatic impairments. Discontinue if abnormal values persist or worsen.
- Monitor serum potassium. May cause hypokalemia.

Implementation ⬆ ⬇

Do not interchange capsules and oral solution. Only oral solution is effective for oropharyngeal candidiasis. Oral solution is not recommended for initial treatment of patients at risk for systemic candidiasis.
Administer with a full meal to minimize nausea and vomiting and to increase absorption.
- Do not administer with antacids or other medications that may increase gastric pH; may decrease absorption of itraconazole.
PO: Administer capsules with food, preferably a full meal.DNC: Swallow capsules whole; do not chew, crush, or break capsules. Do not interchange with other itraconazole products.
Oral Solution: Administer without food if possible. Swish solution in mouth vigorously, 10 mL at a time, for several seconds; then swallow.

Patient/Family Teaching ⬆ ⬇

Explain purpose and side effects of isavuconazonium to patient. Instruct patient to take medication as directed, even if feeling better. Doses should be taken at the same time each day. Advise patient to read Patient Information before starting therapy and with each Rx refill in case of changes.
May occasionally cause drowsiness, dizziness, or blurred vision. Caution patient to avoid driving or other activities requiring alertness until response to medication is known.
Instruct patient to notify health care professional immediately if signs and symptoms of liver dysfunction (unusual fatigue, ↓ appetite, nausea, vomiting, jaundice, dark urine, or pale stools), HF (shortness of breath, swelling, weight gain), or peripheral neuropathy (numbness/tingling in hands feet) occur.
Advise patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to consult with health care professional before taking other medications.
Advise patient to use sunscreen and wear protective clothing to prevent photosensitivity reactions.
May cause hearing loss; usually resolves when treatment is stopped, but can persist. Advise patient to discontinue therapy and notify health care professional if any hearing loss symptoms occur.
Rep: May cause fetal harm. Advise females of reproductive potential to use effective contraception during therapy and for 2 mo after last dose and to avoid breastfeeding during therapy. Advise patient to notify health care professional if pregnancy is planned or suspected.
