Amphotericin B injection can cause serious side effects. It should only be used to treat potentially life-threatening fungal infections and not to treat less serious fungal infections of the mouth, throat, or vagina in patients with a normal immune system (body's natural protection against infection).
Talk to your doctor about the risks of receiving amphotericin B injection.
WHY is this medicine prescribed?
Amphotericin B injection is used to treat serious and potentially life-threatening fungal infections. Amphotericin B injection is in a class of medications called antifungals. It works by slowing the growth of fungi that cause infection.
HOW should this medicine be used?
Amphotericin B injection comes as a solid powder cake to be made into a solution and then injected intravenously (into a vein) by a nurse or a doctor. Amphotericin B injection is usually infused (injected slowly) intravenously over a period of 2 to 6 hours once daily. Before you receive your first dose, you may receive a test dose over 20 to 30 minutes to see if you can tolerate the medication. The length of your treatment depends on your general health, how you tolerate the medication, and the type of infection you have.
You may experience a reaction while you receive a dose of amphotericin B injection. These reactions usually happen 1 to 3 hours after starting your infusion and are more severe with the first few doses. Your health care provider may prescribe other medications to decrease these side effects. Tell your doctor immediately if you experience any of these symptoms while you receive amphotericin B injection: fever, chills, loss of appetite, nausea, vomiting, dizziness, breathing problems, or headache.
You may receive amphotericin B injection in a hospital or you may use the medication at home. If you will be using amphotericin B injection at home, your healthcare provider will show you how to infuse the medication. Be sure that you understand these directions, and ask your healthcare provider if you have any questions. Ask your healthcare provider what to do if you have any problems infusing amphotericin B injection.
If your symptoms do not improve or get worse while receiving amphotericin B, tell your doctor. If you still have symptoms of infection after you finish amphotericin B injection, tell your doctor.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
