Don't take it! Antibiotics will only make it worse. You need to cleanse your body, tone-down your stress levels and eat a healthy diet. If you take the Antibiotics it will damage your body even more and when your body becomes resistant to that particular anitbiotic (and it will!) your face will look so much worse.
Listen to your gut. Get a holistic Acne book and detox your body. I would suggest Acne No More at acnenomore.com and there are others that have been suggested here on this forum. Cleanse your bowels, kidney and liver. Rebalance your body and you will feel better then ever. Good luck and many blessings,
