Cryptococcal meningitis is a fungal infection of the tissues covering the brain and spinal cord. These tissues are called meninges.

Antifungal medicines are used to treat this form of meningitis. Intravenous (IV, through a vein) therapy with amphotericin B is the most common treatment. It is often combined with an oral antifungal medicine called 5-flucytosine.
Another oral medication, fluconazole, in high doses may also be effective against this infection, and may be prescribed later.
People who recover from cryptococcal meningitis need long-term treatment with medication to prevent the infection from coming back. People with weakened immune systems, such as people with AIDs, will also need long-term treatment to improve their immune system.
These complications may occur from this infection:
Amphotericin B can have side effects, including chills and stiffness, and sometimes kidney damage.
