Noxafil uses
Noxafil is an antifungal used to prevent invasive Aspergillus and Candida infections in high-risk patients, such as those who are severely immunocompromised. It is available with a valid prescription.
The oral suspension is used to treat fungal infections in the mouth and throat (thrush).
Noxafil formulations
Noxafil comes in an injection (18 mg/mL), oral tablets (100 mg), and an oral suspension (40 mg/mL).
Directions
Take Noxafil exactly as prescribed by your doctor. Carefully read the information that comes with your prescription. Talk to your doctor or pharmacist about any questions or concerns you may have.
Your doctor will determine which formulation to use, how much medication you should take, and how long your treatment will last based on the condition being treated.
Noxafil injection is typically administered by intravenous infusion over 30-90 minutes.
Noxafil tablets should be taken with food. They should not be broken, crushed, or chewed.
Noxafil oral suspension should be shaken well before use. Each dose should be taken during or within 20 minutes of a meal. If you are unable to eat a full meal, each dose should be taken with a liquid nutritional supplement or an acidic carbonated beverage.
If you miss a dose, take it as soon as you remember. However, if it’s almost time for the next dose, skip the missed dose and proceed with the regular dosing schedule. Do not double dose to make up for a missed dose.

- Noxafil injection should be refrigerated at 36°F to 46°F (2°C to 8°C).

Cautions
- Before you start treatment with Noxafil, talk to your doctor about:
- All the prescription and over-the-counter medications you take
- Your allergies
- Your current health problems and past medical history
- Your pregnancy or breastfeeding status
- Noxafil increases the drug levels of cyclosporine and tacrolimus in the body; dose reductions may be needed.
- Noxafil can cause a heart arrhythmia called QTc prolongation.
- Liver enzymes can increase.
- Patients with kidney problems should not use the Noxafil injection unless the benefits outweigh the risks.
- Noxafil can prolong the hypnotic or sedative effects of midazolam. Patients should be monitored and benzodiazepine receptor antagonists should be available.
Side Effects
Diarrhea, nausea, fever, vomiting, headache, coughing, and low blood potassium levels are some Nofaxil side effects. However, these are not all the side effects that can occur. Contact your doctor right away if you have side effects that bother you or won’t go away.
