Before Using amphotericin b
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For amphotericin b, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to amphotericin b or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Interactions with Medicines
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Interactions with Food/Tobacco/Alcohol
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
Proper Use of amphotericin b
Apply enough amphotericin B to cover the affected areas, and rub in gently.
Do not apply an occlusive dressing (airtight covering such as kitchen plastic wrap) over amphotericin b since it may cause irritation of the skin. If you have any questions about this, check with your doctor.
To help clear up your infection completely, it is very important that you keep using amphotericin b for the full time of treatment , even if your symptoms begin to clear up after a few days. Since fungus infections may be very slow to clear up, you may have to continue using amphotericin b every day for several months or longer. If you stop using amphotericin b too soon, your symptoms may return.
Do not use this product in your eyes.
