Before using micafungin

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 micafungin, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to micafungin 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.

Pediatric

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of micafungin injection to treat candidemia, acute disseminated candidiasis, candida peritonitis and abscess, esophageal candidiasis, and prevent candida infections with stem cell treatment in children 4 months of age and older.

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of micafungin injection to treat candidemia, acute disseminated candidiasis, candida peritonitis and abscess without meningoencephalitis or ocular dissemination in children younger than 4 months of age. However, safety and efficacy of micafungin infection have not been established for the treatment of candidemia with meningoencephalitis or ocular dissemination in children younger than 4 months of age.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of micafungin injection in the elderly.

Breastfeeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

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. When you are receiving micafungin, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Using micafungin with any of the following medicines may cause an increased risk of certain side effects, but using both drugs may be the best treatment for you. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.

  • Nifedipine
  • Sirolimus

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.

Other medical problems

The presence of other medical problems may affect the use of micafungin. Make sure you tell your doctor if you have any other medical problems, especially:

  • Bleeding problems (eg, hemolysis or hemolytic anemia) or
  • Kidney problems or
  • Liver problems—Use with caution. May make these conditions worse.

Proper use of micafungin

A nurse or other trained health professional will give you or your child micafungin. Micafungin is given through a needle placed in one of your veins. Micafungin is given slowly, so the needle will have to remain in place for at least 1 hour.
