acne
"I was prescribed first the Z-pack and took that for 5 days and then to continue by taking one minocycline 100 mg capsules (once a day) for adult cystic acne.  I was feeling fine the first week on minocycline but the second week, I had to completely take myself off the minocycline because I was miserable. First, it was sinus, then sinus headaches with blurry visions on and off.  Then my joints started hurting, especially in my hands and lower back.  I also felt dizzy when moving too fast from one position to another and started to feel like I was under a haze all the time. "
