After using proactive should my acne go away?

Maybe. If it fails, you should be able to get a rx. I start with topical Clindamycin with or without a retinoic acid derivative. If needed after a few weeks, consider adding an oral antibiotic such as Erythromycin or tetracycline / Minocycline as suitable for the individual. Dermatologists have the big guns -- accutane, lasers. Freedom from acne should be a person's right. Good luck.
