Many people stop if they feel better. This is not a good idea. When this happens, the drug will stop working. For example, if you are taking fluconazole to fight thrush and you miss too many doses, the thrush in your body could develop resistance to fluconazole. Then you would have to take a different drug or combination of drugs to fight thrush.
Many doctors prefer to treat thrush with creams, or lozenges that dissolve in the mouth.
Thrush is much less likely to develop resistance when the treatment is applied directly to the infection instead of through the whole body. Fluconazole is available in several forms. It is also available in granules to prepare a liquid form, and as a liquid for intravenous use. The dose and the length of time you will take it depend on the type of infection you have. If you have had kidney problems, your doctor might need to reduce your dose of fluconazole.
