"i went to dermatologist because of some minor adult acne on my chin and was prescribed minocycline 100mg one a day. well come nov 1 will be 1 month in, and the very couple of acne i had on my chin has tripled plus i now have it on my cheeks, which i never had a problem before. plus i have had some side effects as well, including dizziness, nauseas and yeast infection. it was prescribed to me for 3 months. i will stick with it for another 2 mths and see what happens. as of right now i am disappointed, but am hoping to see positive results in next 2 mths."
