Below is a summary of the dosage, administration, reconstitution and
storage details for Fungizone 50mg Powder for Sterile Concentrate.
Reference should be made to the Summary of Product Characteristics
for full prescribing information.
Adults and children: Fungizone should be administered by
intravenous infusion over a period of 2-4 hours. Reduction of the
infusion rate may reduce the incidence of side effects. In rare instances
infusion times of up to 6 hours may be necessary. Initial daily dose
should be 0.25 mg/kg of body weight gradually increasing to a level of
1.0 mg/kg of body weight depending on individual response and
tolerance. Within the range of 0.25-1.0 mg/kg the daily dose should be
maintained at the highest level which is not accompanied by
unacceptable toxicity.
In seriously ill patients the daily dose may be gradually increased up
to a total of 1.5 mg/kg. Since amphotericin B is excreted slowly,
therapy may be given on alternate days in patients on the higher
dosage schedule. Several months of therapy are usually necessary; a
shorter period of therapy may produce an inadequate response and
lead to relapse.
When commencing all new courses of treatment, it is advisable to
administer a test dose immediately preceding the first dose. A volume
of the infusion containing 1mg (i.e. 10mL) should be infused over 2030 minutes and the patient carefully observed for at least a further 30
minutes. It should be noted that patient responses to the test dose
may not be predictive of subsequent severe side effects.
Whenever medication is interrupted for a period longer than seven
days, therapy should be resumed by starting with the lowest dosage

level, i.e. 0.25 mg/kg of body weight and increased gradually.
Safety and effectiveness in paediatric patients have not been
established through adequate and well-controlled studies. Systemic
fungal infections have been treated in paediatric patients, with reports
of side effects similar to those seen in adults.
Under no circumstances should a total daily dose of 1.5 mg/kg be
exceeded. The recommended concentration for intravenous infusion
is 10 mg/100 mL.
Elderly: No specific dosage recommendations or precautions.
Reconstitute as follows: An initial concentrate of 5 mg amphotericin B
per ml is first prepared by rapidly expressing 10ml sterile water for
injection, without a bacteriostatic agent, directly into the lyophilized
cake, using a sterile needle (minimum diameter: 20 gauge) and syringe.
Shake the vial immediately until the colloidal solution is clear. The
infusion solution, providing 10mg/100mL is obtained by further dilution
(1:50) with 5% Glucose Injection of pH above 4.2. The pH of each
container of Glucose Injection should be ascertained before use.
Commercial Glucose Injection usually has a pH above 4.2; however, if
it is below 4.2 then 1 or 2 ml of buffer should be added to the Glucose
Injection before it is used to dilute a concentrated solution of
amphotericin. The recommended buffer has the following
Dibasic sodium phosphate (anhydrous) 1.59 g
Monobasic sodium phosphate (anhydrous) 0.96 g
Water for Injections BP q.s. to 100 mL
The buffer should be sterilised before it is added to the Glucose
Injection, either by filtration through a bacterial filter, or by autoclaving
for 30 mins at 15 lb pressure (121°C).

5. How to store your medicine
Keep this medicine out of the sight and reach of children.
Unopened product will be stored in a refrigerator (2-8°C) in the
pharmacy and should not be used after the expiry date shown on the
This medicine will be prepared in a special area before the doctor or
nurse gives it to you. After being mixed together the medicine will be
kept for no more than 8 hours at room temperature (25°C) or 24 hours
in a refrigerator (2-8°C). It should be stored protected from light.

Aseptic technique must be strictly observed in all handling, since no
preservative or bacteriostatic agent is present. Do not reconstitute
with saline solutions.
The use of any diluent other than the ones recommended or the
presence of a bacteriostatic agent in the diluent may cause
precipitation of the amphotericin. Do not use the initial concentrate or
the infusion solution if there is any evidence of precipitation of foreign
An in-line membrane filter may be used for intravenous infusion of
amphotericin; however the mean pore diameter of the filter should not
be less than 1.0 micron in order to assure passage of the amphotericin
Other preparations for injection should not be added to the infusion
solution or administered via the cannula being used to administer
Fungizone. The use of Fungizone by other routes has been
documented in the published literature:
Bladder irrigation/instillation (eg candiduria): Continuous irrigation
with 50mg Fungizone in 1 litre sterile water each day until urinary
cultures are negative. Intermittent use of volumes of 100-400mL
(concentrations of 37.5-200 mcg/mL) has also been reported. The
urine should be alkalinized (with potassium citrate) and antifungal
ointment applied to the perineal area.
Lung inhalation (eg pulmonary aspergillosis): 8-40 mg amphotericin
B (nebulized in sterile water or 5% Glucose) has been given daily in
divided doses. Concurrent eradication of oral and intestinal yeast
reservoirs is recommended.

Intrathecal (eg coccidiodal meningitis): Patients who do not
respond to fluconazole or itraconazole would be candidates for
intrathecal amphotericin B therapy with or without continuation of
azole treatment. The intrathecal dosage of amphotericin B normally
ranges between 0.1mg and 1.5mg per dose, administered at intervals
ranging from daily to weekly, beginning at a low dosage and increasing
the dosage until the appearance of patient intolerance. Amphotericin
B is irritating when injected into the CSF.
Other: Other uses of solutions prepared using Fungizone include local
instillations for the treatment of fungal infections of the ear, eye,
peritoneum, lung cavities and joint spaces.
Vials of powder for reconstitution should be stored in a refrigerator.
Reconstituted: After reconstitution with 10 mL sterile Water for
Injections the concentrate
(5 mg/ml) should be stored protected from light. Chemical and
physical in-use stability has been demonstrated for 8 hours at up to 25
°C and 24 hours at 2-8 °C.
From a microbiological point of view, due to the absence of any
microbial preservative, the product should be used immediately. If not
used immediately, in-use storage times and conditions prior to use
are the responsibility of the user. These would normally not be longer
than 24 hours at 2-8 °C unless reconstitution has taken place in
controlled and validated aseptic conditions. It is not intended as a
multidose vial. Any unused material should be discarded. Solutions
prepared for intravenous infusion (i.e. 10 mg or less amphotericin per
100 mL) should be used promptly after preparation.
