What is the most effective way to drink fluconzole 150 mg to treat yeast infection. 1 pill 150 mg every other day, or every three days?

Every day. There is a common treatment for mild or uncomplicated vaginal candidiasis ('yeast infection) that calls for a single (one time) dose of 150 mg of flucanazole. I recommend you follow your doc's rx. If given multiple doses - more benefit if taken every day, but should not take for more than 3 to 5 days. I commonly give 100 mg per day for thrree days in a row and find it effective.
