Cidofovir

Cidofovir is an antiviral medication used to treat certain viral infections, particularly cytomegalovirus (CMV) retinitis in people with weakened immune systems. It works by interfering with the virus's ability to replicate its DNA, thereby preventing the spread of the infection. Cidofovir is administered through injections, often in a healthcare setting, and requires careful monitoring due to potential side effects like kidney damage. It is especially useful when other treatments are not effective and is an important option in managing severe viral infections in immunocompromised patients.
