- Cyclosporin plasma concentrations should be monitored and appropriate dosage
adjustments made when used with amphotericin B or fluconazole.

- Antiviral therapy.

- Prophylaxis for Pneumocystis carinii pneumonia.

relapse after prior therapy. The success of prior therapy must have been documented
by negative CSF culture at the end of therapy.
