Minocycline is believed to hamper reabsorption of cerebrospinal fluid in the brain, potentially creating intracranial hypertension and vision loss. In fact, doctors know about this side effect, and it has been well documented. For someone with already slowed venous flow and build-up of CSF (as a patient with CCSVI), this side effect could be even more harmful.
