Acne
"Please DO not use minocycline for acne. This drug caused me to contract psuedotumor cerebri (a pretty serious brain condition) I had been on my dosage of 100mg x2 per day for about a month. About two weeks in I began to have horrible headaches, which persisted throughout the whole day. One night the headache became so unbareable I needed to go into the ER. I was diagnosed with an intractable headache and send home after a few IV bags. My headaches persisted but I ignored them and thought possibly the heat was causing them. About 2 weeks after my first visit I began to have double vision. I called my doctor and they order a MRI immediately. The MRI showed a build up of pressure on my optic nerve, caused by minocycline."
