Controlled trials of benzathine penicillin in the treatment of neurosyphilis are reviewed, as are recent case reports of benzathine penicillin failures. Although few well-controlled studies exist to document conclusively the efficacy of benzathine penicillin in the treatment of neurosyphilis, its use is recommended in selected situations.
