The treatment of TB meningitis is isoniazid, rifampicin, pyrazinamide and ethambutol for two months, followed by isoniazid and rifampicin alone for a further ten months.  Steroids are always used in the first six weeks of treatment (and sometimes for longer).  A few patients may require immunomodulatory agents such as thalidomide. Treatment must be started as soon as there is a reasonable suspicion of the diagnosis.  Treatment must not be delayed while waiting for confirmation of the diagnosis.
