About a year ago I was prescribed Dynacin or Minocycline for my acne. After a couple of months I noticed that I felt depressed, moody, and I started to break out in hives or rashes (not certain if drug caused). On top of that the medication did nothing for my acne! Save your money and stick to cleansing and treating acne with anything but oral antibiotics. Try these products: Cetaphil soap bar for cleansing, differin gel at night, and benzaclin or something with benzyl peroxide not more then 5% in the morning. Hope this helps!
