But since a month her acne has flared up again,it's mostly pus filled. Please tell, .how long do we have to take minolox(antibiotics) so that acne completely goes away? .if we stop taking the medicine will the acne always come back?then she can never stop the medicine .won't there be side effects? .is there any other way to cure pus filled acne problem? The doctor had also prescribed vitamin supplements for hairfall issue.Do these supplements also help in acne problem?
