Diflucan (Fluconazole) Dosage and Usage , Overdosing, Miss a Dose
Diflucan (fluconazole) is an antifungal medication used for the treatment of fungal skin infections, vaginal and oral candidiasis, thrush, and other fungal infections. It may be used to treat an existing infection, or as a prophylaxis that will prevent a fungal infection. As a prophylaxis, it is given to persons with a weakened immune system, especially AIDS patients, persons who are undergoing chemotherapy or cancer treatment, and persons who are about to receive an organ or bone marrow transplant.
Diflucan is a prescription medicine, hence only a doctor can prescribe it for a patient that he has examined and considers to be someone who can safely take the drug. People with liver, heart or kidney problems generally are not prescribed diflucan because the drug may aggravate their medical condition. Pregnant women and breastfeeding mothers are also not given diflucan because it may harm their baby. Furthermore, people taking certain medications that unfavorably interact with diflucan are given other antifungals instead.
It is also the doctor who determines the proper dosage and the form by which diflucan is to be administered. The drug may be taken as a tablet, as an injection, or as a suspension. The diflucan daily dosage varies depending on the specific type of infection and the purpose (for treatment or as prophylaxis).
For vaginal candidiasis, the diflucan daily dosage may be 150 mg/day over a course of two weeks. For prophylaxis, the diflucan daily dosage will not apply; instead, a weekly dose of 150 to 300 mg may be administered. The same weekly dosage may be used for resistant fungal skin infections. Meanwhile, more severe and systemic fungal infections, such as meningitis, will require greater dosages. In these cases, a diflucan daily dosage of 500 to 600 mg/day may be appropriate. In very severe cases, as much as 800 mg/day diflucan daily dosage may be called for.
Children require different dosages from adults. The pediatric dosage often ranges from 6 to 12 mg/kg/day. Suspension liquids are generally preferred over the tablet form for children.
For both children or adults, a larger initial dose may be given, usually double or 150% of the subsequent amounts to be given. This is called the “loading dose.” For example, an initial loading dose of 200 mg of diflucan may be given on the first day, and then on the succeeding days, the diflucan daily dosage will be 150 mg/day.
It is always the doctor who determines the correct dosages, and the patient must strictly adhere to the doctor’s instructions. He should not take more or less than what is prescribed, nor for a longer or shorter time than the duration specified. The symptoms of infection may subside five or six days after the treatment with diflucan was started, but if the prescription is for two weeks, then the drug must be taken for two whole weeks.
If a dose is missed, the person must take the medicine as soon as he remembers to take it. But if he remembers close to the time when the second dose is to be taken, then he should take only one dose, not two. Double dosing is dangerous, and it should be avoided. With diflucan, it is safer to under-dose than to overdose. If there is an overdose—often marked by mental confusion or unusual behavior—the person must seek medical help right away.
