I had a yeast infection n had sex with my partner now he has the same symptoms he took 3pills of 150g diflucan (fluconazole) hw long does it take to work?

Diflucan (fluconazole) . one dose for diflucan (fluconazole) is usually sufficient. If not eradicated after 2doses there is a resistant strain or wrong diagnosis. Results are usually seen within 3 days!
