Uses for CanesOral
Fluconazole is used to treat serious fungal or yeast infections, including vaginal candidiasis, oropharyngeal candidiasis (thrush, oral thrush), esophageal candidiasis (candida esophagitis), other candida infections (including urinary tract infections, peritonitis [inflammation of the lining of the stomach], and infections that may occur in different parts of the body), or fungal (cryptococcal) meningitis. This medicine works by killing the fungus or yeast, or preventing its growth.
Fluconazole is also used to prevent candidiasis in patients having bone marrow transplants who receive cancer or radiation treatment.
This medicine is available only with your doctor's prescription.
Before using CanesOral
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 this medicine, the following should be considered:
Allergies
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine 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 fluconazole in children 6 months to 13 years of age. However, safety and efficacy have not been established in children younger than 6 months of age.
Geriatric
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of fluconazole in the elderly. However, elderly patients are more likely to have age-related kidney problems, which may require an adjustment in the dose for patients receiving fluconazole.
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.

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.
