The yeast infection candidiasis, or thrush, is fairly common. However, it can be more serious in people whose immune systems have been weakened by HIV infection. See Fact Sheet 516 for more information on thrush . Another opportunistic infection, cryptococcal meningitis , is discussed in Fact Sheet 503 . Fluconazole has been approved to treat both of these infections.
Some doctors also use fluconazole to treat other opportunistic infections caused by fungus.
Whenever you take medication, be sure to take all of the prescribed doses. 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.
