Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Canesoral.
General: If this is your first yeast infection, if you have frequent yeast infections or heart disease, if you have another yeast infection within 2 months after taking Canesoral, or if you have multiple sexual partners or change partners often, talk to your doctor or pharmacist before taking Canesoral. Canesoral should only be taken as a single dose.
The following symptoms are not caused by a yeast infection. Contact your doctor for treatment advice, if you experience them:
- abdominal pain
- discharge with a foul odour
- fever or chills
- lower back or shoulder pain
- nausea, vomiting, or diarrhea
- painful urination
If your symptoms have not improved in 3 days or disappeared in 7 days, contact your doctor.
Grapefruit juice: Taking fluconazole at the same time as drinking grapefruit juice may cause fluconazole to build up in the body and cause side effects. Avoid drinking grapefruit juice if you are taking Canesoral.
Intercourse and birth control: Vaginal intercourse should be avoided when women have a yeast infection. This will help reduce the risk of infecting your sexual partner(s).
Canesoral works in the body for several days after you take the dose. To avoid the risks of harm to the developing baby, if you are child-bearing age and may become pregnant, be sure to use an effective form of birth control for 7 days after taking Canesoral.
QT prolongation: Canesoral can cause changes in the electrical activity of the heart, called QT prolongation. If you have heart disease, abnormal electrolyte levels (e.g., potassium, sodium), or are taking other medications that can cause QT prolongation (e.g., quinidine, Amiodarone), discuss with your doctor how Canesoral may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Canesoral, and whether any special monitoring is needed.
Pregnancy: Canesoral should not be used during pregnancy unless the benefits outweigh the risks. Women who take fluconazole for vaginal yeast infections and who may become pregnant should useadequate birth control for seven days after a dose of fluconazole.
Breast-feeding: Canesoral passes into breast milk. If you are a breast-feeding mother and are taking fluconazole, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children and adolescents: The safety and effectiveness of fluconazole 150 mg capsules have not been established for the treatment of vaginal candidiasis in children under 12 years of age.
