Welcome to HealthcareMagic forum,
You seems to be having pimples
on the back and FLUCOS 150 is NOT the medicine for that.Flucos is an antifungal medicine.Since you are 23 ys of age ,you can take Tab Azithromycin
(500mg) once daily for 3 days.This is to be taken 1 hr before food.Also start using nadibact cream locally over pimples in day .In night use Adaferin gel over pimples.Dermatologist
consultation would help you further.
