"solodyn was touted as being &#039;new&#039; from my dermatologist after i tried many other antibiotics (tetracycline, minocycline, and erythromycin all in various stages of potency). even though solodyn is really minocycline, it&#039;s a extended release version of the antibiotic which is supposed to give a more consistent stream into your body. 

after using the product for over six months i have noticed no further nodular outbreaks on my back or neck area. my chest has also calmed down about 80% from before (red nodes, cystic acne, now down to small red bumps here and there). it is expensive. "
