Amphotericin B Liposome (Intravenous)

As both an antifungal and antiprotozoal medication, Amphotericin B liposomal complex is used for treating a variety of serious fungal and protozoan infections.


Amphotericin B liposomal complex, or simply, Amphotericin B liposome, works by inhibiting the growth of fungi that cause infections. It is usually given to patients who cannot tolerate, or do not respond well to, the conventional amphotericin treatment (Amphotericin B injection).

Amphotericin B liposome is only used for treating severe, life-threatening fungal infections such as visceral leishmaniasis and a certain type of meningitis in patients infected with the HIV virus. This medication is not used to treat minor fungal infections, such as a yeast infection of the esophagus, mouth, or vagina.

  • Protozoan infections

Amphotericin B liposome comes in the form of a suspension (liquid) and is to be administered intravenously (injected into a vein). The intravenous infusion is usually done once daily as per the doctor's instructions. It is normally injected slowly over a period of 2 hours. If the patient tolerates the initial doses well, the medication may be administered over a period of 1 hour. The dosages and length of treatment depend on how well your body tolerates the medication, the type of infection being treated, and your general health.

While receiving a dose of amphotericin B liposomal injection, you may experience a reaction. Such reactions typically happen 1- 3 hours after the infusion starts, and are more severe during the initial doses. Your doctor may prescribe other medications to alleviate these side effects.

Amphotericin B liposomal injection may be done in a hospital or at home. Your healthcare professional will show you how to infuse the medicine if you will be using amphotericin B liposome at home. Make sure you understand the instructions given and ask any questions you may have. Additionally, before using the medication, check the product visually for discoloration or particles. Do not use the liquid if either is found.

To treat certain infections, it may be necessary to use this medication for several weeks or months. Stopping the therapy too early may result in re-infection. Let your doctor know if your symptoms fail to improve or get worse while using amphotericin B liposome.

While receiving amphotericin B liposome, your blood pressure, breathing and other vital signs will be monitored closely. You may need to take frequent blood tests. Kidney and liver function may also need to be tested. It is therefore important that you keep your appointments with your healthcare professionals.

Missed dose:

If you happen to miss a dose, take it as soon you remember. You should, however, go back to the regular schedule if it's almost time for the next scheduled dose. Do not attempt to make up for the missed dose by double dosing.
